Chesapeake Bay Program
The Chesapeake Bay Program is a unique regional partnership leading and directing
the restoration of the Chesapeake Bay since 1983. The Chesapeake Bay Program
partners include the states of Maryland, Pennsylvania and Virginia; the District of
Columbia; the Chesapeake Bay Commission, a tri-state legislative body; the U.S.
Environmental Protection Agency (EPA), which represents the federal government; and
participating citizen advisory groups.
In the 1987 Chesapeake Bay Agreement, Chesapeake Bay Program partners set a goal
to reduce the nutrients nitrogen and phosphorus entering the Bay by 40 percent by the
year 2000. In the 1992 Amendment to the Chesapeake Bay Agreement, partners
agreed to maintain the 40 percent goal beyond the year 2000 and to attack, nutrients
at their sourceupstream in the tributaries. The Chesapeake Executive Council, made
up of the governors of Maryland, Pennsylvania and Virginia; the mayor of
Washington, D.C.; the EPA administrator; and the chair of the Chesapeake Bay
Commission, guided the restoration effort in 1993 with five directives addressing key
areas of the restoration, including the tributaries, toxics, underwater bay grasses, fish
passages and agricultural nonpoint source pollution. In 1994 partners outlined
initiatives for habitat restoration of aquatic, riparian and upland environments;
nutrient reduction in the Bay's tributaries; and toxics reductions, with an emphasis on
pollution prevention.
The 1995 Local Government Partnership Initiative engages the watershed's 1,650
local governments in the Bay restoration effort. The Chesapeake Executive Council
followed this in 1996 by adopting the Local Government Participation Action Plan
and the Priorities for Action for Land, Growth and Stewardship in the Chesapeake
Bay Region, which address land use management, growth and development, stream
corridor protection and infrastructure improvements. A 1996 riparian forest buffers
initiative furthers the Bay Program's commitment to improving water quality and
enhancing habitat with the goal of increasing riparian buffers on 2,010 miles of stream
and shoreline in the watershed by the year 2010.
Since its inception, the Chesapeake Bay Programs highest priority has been the
restoration of the Bays living resources -its finfish, shellfish, bay grasses, and other
aquatic life and wildlife. Improvements include fisheries and habitat restoration,
recovery of bay grasses, nutrient reductions and significant advances in estuarine
science.

BIOLOGICAL AND LIVING RESOURCES
MONITORING DATA
INTRODUCTION
The 2000 User's Guide is intended to help data users to access and use biological and
living resources monitoring data collected in the Chesapeake Bay and its tidal tributaries. This
guide describes many of the biological and living resources databases currently available through
the Chesapeake Information Management System in standardized structures and formats (CIMS
databases). It describes where the data and data products reside and how to obtain them. For
the first time, this guide also includes guidance for calculating standard ecosystem indicators and
summary statistics derived from the monitoring data.
Chesapeake Information Management System
In 1996 the Chesapeake Executive Council adopted the Strategy for Increasing Basin-
wide Public Access to Chesapeake Bay Information. This strategy calls for partners in the
Chesapeake Bay Program to develop the Chesapeake Information Management System (CIMS).
CIMS will electronically link a variety of information about the Bay and rivers and make this
information available electronically through the Internet to anyone, from students, to scientists to
citizens. The information targeted for distribution through CIMS includes technical and public
information, educational material, environmental indicators, policy documents and scientific data.
(See Figure 1.)
As a result of the CIMS initiative the various federal, state, academic and non-
governmental organizations are working to establish a system of distributed databases. In the
ideal system, a CIMS database would be created, managed, reside with, and be made directly
available from the data originator's institution on an Internet server. All the data would eventually
be retrievable from a single web site. This system has several advantages over a single data
repository. Primarily, the people with the most expertise and knowledge about the data-trie data
originators-will manage the data. Additional advantages include reduced costs due to elimination
of intermediate data handling at a central repository, and decreased the time between collection
and release of the data.
Chesapeake Bay Program Data Center
The EPA CBP presently maintains a Data Center at its main office in Annapolis,
Maryland. The Data Center provides data management, GIS and technical support to program
participants to accomplish the goals agreed on by the Chesapeake Executive Council. The Data
Center manages computer hardware and software, provides user support and training for these
computer resources, acquires and stores data sets and provides analytical support for CBP
activities. The CBP Data Center is intended to be one of many geographically distributed data
centers in the Chesapeake Bay Watershed as the CIMS network evolves. Recipients of Data
Center services are the CBP subcommittees, CBP resource managers and the watershed's
scientific community and stakeholders.
The primary information and data analysis system for the Annapolis Data Center are a
network of web, database and GIS servers, running on the Microsoft NT platform. Other high-
level computing needs are met with a variety of UNIX workstations. Routine staff computing
Introduction
-------
needs are met with the multiple-networked IBM compatible workstations. The DEC Alpha 3800
Computer (CHESIE), which was the heart of the CBPO information processing system for many
years, was retired in September of 1999.
The Information Pyramid
During the development of the current CBP data management philosophy, it was
recognized that information used by the Bay Program is not exclusively monitoring data. Five
basic kinds of information were identified as being collected, used or generated by the CBP
participants. These types of data were identified and described in detail in the 1996 Chesapeake
Bay Program document Chesapeake Bay Program Information Management Requirements and
Recommendations (EPA Contract Number 01-08833-07-3872-005). The data types can be
described as follows:
Technical Data - Field sampling and laboratory results
Raw Data - Original field sampling and laboratory results
Primary Data - Information submitted and exchanged as is by data providers
Chesapeake Bay Program Data - Information reviewed (e.g. QA/QC) and processed
according to CBP standards and specifications
Maps and Analyzed Data - Summary results from data analysis including ecosystem
indicators, graphics and maps.
Status and Trends - Highly summarized data designed to tell a story about the health of
the Bay.
Publication - Technical reports, technical publications and summary reports based on
analyzed data.
General Information - News accounts, press releases, fact sheets and information
summaries based on results from data analysis.

The 1999 Users Guide to CBP Biological and Living Resources Monitoring Data
The Living Resources Biological Monitoring Data Management Program
The Biological Monitoring Data Management Program (BMDMP) has traditionally focused
on the lower levels of the information pyramid, the Technical Data and the Analyzed Data. Data at
these levels consists of:
Raw data: Typically the original field and laboratory results of monitoring programs. Data
are collected and managed offsite by the data originators and not available from the
CBP data center.
Primary data: Delivered to the CBP Data Center by the data originators. Many data sets
are currently available from the Data Center "as is" with their existing documentation. A
long-term goal of the CBP Data Center is to work with the data originators to produce
primary data sets that meet or come close to CIMS standards and specifications, and to
de-emphasize use of primary data in favor of "CIMS data."
CBP Data: CBP monitoring databases or CIMS compliant databases which are available
through the CIMS partners. All CIMS-compliant databases follow common data
dictionaries and data reporting standards. Biological and living resources point data
become CIMS data after they are placed in uniform, relational databases. Prior to
loading data into the databases, data are rigorously checked for duplicate fields, outliers,
erroneous data and other errors, and problems in the data are resolved with the data
providers. Biological and living resources point data in CIMS database structures are
currently stored in relational databases and as comma or pipe delimited, ASCII flat files
on CBP Data Center Servers and the CBP-CIMS Internet home page.
Ecosystem Indicator data: Databases of technical indicators derived from monitoring
data are now becoming available. The information is calculated from water quality,
biological and living resources CBP databases using accepted algorithms and/or CIS
methods. These forms of the data are expected to be most useful to CBP participants
and resource managers.
The BMDMP has had a major influence on the establishment of CIMS and continues to
be a major contributor to the CIMS effort. The BMDMP has helped establish CIMS standards for
data dictionaries, data documentation and uniform relational database designs. This document is
part of the CIMS data management guidance. The BMDMP has helped to improve the ability of
data generators to produce quality data and establish a number of data generators as distributed
CIMS data sites. In the future the BMDMP will be placing an increased emphasis on
development of more data analysis tools, creating indicators and document level information.

MONITORING DATA CURRENTLY AVAILABLE
THROUGH CIMS
Chesapeake Bay Program and Historical Monitoring Point Data
These data are collected as part of the CBP monitoring program are described briefly
below. Point data are data collected at a single point that can be referred to by a single latitude
and longitude. All of the 1984-present phytoplankton, zooplankton and benthos monitoring data
for the Maryland and Virginia CBP monitoring programs are currently available from the CBP-
CIMS Internet home page. Plankton and benthos data are submitted by generators in
standardized table structure suitable for loading into the relational databases. The Biological
Monitoring Data Manager rigorously QA/QC's the data, loads them into the CIMS relational
database structure, and updates the data documentation provided. The data are published
through an on-line searchable database or as comma or pipe delimited, ASCII flat files in single
calendar year file. Scripts to convert ASCII files into SAS files, data in alternate formats and/or
data on media (disk, tape or CD) are by request.
All CBP funded plankton monitoring data (phytoplankton, zooplankton and fluorescence)
are routinely updated in six-month increments. Data collected between January and June of the
current calendar year are added to the databases in December of the same year. Data collected
between July and December are added to the database by May of the following year. CBP
benthic monitoring data are updated annually. The previous year's data are available by July of
the following year. Selected historical data sets are also being included in the online databases.
Historic data are being provided to the CBP Data Center on an ongoing basis; please contact the
Biological Data Manager (See Appendix D) for details and data set availability. The URL of the
CBP-CIMS world wide web pages is at http://www.chesapeakebav.net/. FTP data access is also
available at ftp://ftp.chesapeakebay.net./Pub/. File structures (i.e. field names, definitions and
attributes) for the currently available data on the FTP Site provided in Appendix A. Field names
and attributes for data from the on-line databases are provided in Appendix B. A complete list of
CIMS-compliant field names for biological and living resources data sets, and their definitions and
units, are also provided in Appendix B. An explanation of field values and definitions of the
parameter codes used in the CIMS databases are contained in Appendix C. A list of CBPO Data
Center contacts are provided in Appendix D. A complete list of general CIMS data reporting
standards and living resource specific data reporting formats for CBP monitoring data submitters
are included in Appendix E.

something, e.g., a line representing a mapped stream or a point representing a known fish
passage. Interpreted data are raw data that have been manipulated to represent something else,
e.g., monitoring station water quality data that have been interpolated and averaged over three
years to give a picture of conditions throughout the Bay. Summarized data are those that have
been aggregated to represent a value for a larger spatial area. The current version of Bay Atlas
includes the following living resources-related data.

Living Resources and Biological Monitoring Databases Accessible
through CIMS
The CBP partners are working together as part of the CIMS initiative to develop a system
of distributed databases to better utilize the rapid expansion of the Internet and the advancement
of data management practices. In the envisioned distributed database system, data will be
collected, managed and maintained by the data originator. Several distributed databases and
information resources currently exist for Chesapeake Bay data. The following sites represent data
publication provided via the data originator's Internet server.
Chesapeake Bay Submerged Aquatic Vegetation Aerial Surveys
The Chesapeake Bay SAV data were compiled by the VIMS from 1:24,000 scale aen'al
photography. Years for which data exist are 1971; 1974; 1978; 1979 (Maryland only); 1980 and
1981 (Virginia only); 1984 through 1987; and 1989 through 1998. SAV data for 1999 will soon be
available. Also available from VIMS is the Tier I data layer, which is a compilation of the historical
SAV data listed above from 1971 through 1990. The SAV data files are in Arc/Info (ESRI,
Redlands, CA) export format. Data files are served as both PKZIP compressed files for use on
IBM-compatible personal computers and tar.Z compressed files for use on UNIX platforms. Each
file contains both the .eOO Arc/Info export file and also a .bet metadata file. The Internet address
for the VIMS SAV home page is:
http://www.vims.edu/bio/sav/index.html
Chesapeake Bay Chlorophyll Remote Sensing Project
The objective of the remote sensing program is to improve the monitoring of
phytoplankton response to nutrient reductions in the Bay. The distribution of phytoplankton in
estuaries and coastal waters is characterized by high spatial and temporal variability. Thus it is
difficult to quantify phytoplankton in these regions using measurements from ships alone.
Therefore, the National Oceanographic and Atmospheric Administration (NOAA) started a remote
sensing program in 1989 with the goal of determining concentrations of chlorophyll using
measurements of ocean color from aircraft. These data have been enumerated using the Ocean
Data Acquisition System (ODAS), a relatively simple ocean color instrument that was developed
in the mid-1980s by NASA's Goddard Space Flight Center. Since 1997 the remote sensing
SEAWIFS aircraft simulator (SASH) instrument has been implemented for improved
measurements. The Internet address for the ODAS home page is:
http://noaa.chesapeakebav.net/odas sas.html
Virginia Fishery Independent Seine and Trawl Surveys
VIMS has conducted annual trawl and seine surveys since 1955. The primary objective
of the survey is to monitor trends in the abundance of juveniles in about 20 recreationally,
commercially and ecologically important finfish and invertebrates. Since 1955, the trawl survey
has sampled waters from the mouth of the Chesapeake Bay north to the freshwater interfaces of
the James, York, and Rappahannock rivers. Samples from about 60 stations are collected every
month. At each station, a 30-foot-wide shrimp trawl is towed for five minutes.
A seine survey for juvenile striped bass was initiated in 1967, but was briefly suspended
between 1973 and 1980, due to lack of funding. An indexes of abundance has been calculated
every year since 1980 and this is the second longest continuous striped bass index in the U.S.

Environmental Monitoring and Assessment Program (EMAP) Data
The EPA's Environmental Monitoring and Assessment Program (EMAP) is a research
program dedicated to developing the tools necessary to monitor and assess the status and trends
of national ecological resources. EMAP's goal is to develop the scientific understanding for
translating environmental monitoring data from multiple spatial and temporal scales into
assessments of ecological conditions and forecasts of the future risks to the sustainability of our
natural resources. EMAP's research supports the National Environmental Monitoring Initiative of
the Committee on Environment and Natural Resources (CENR). The EMAP program provides
both point data sets and GIS databases for its study areas. EMAP data for the Chesapeake Bay
Region (the Virginian Province) and the rest of North America are available at:
http://www.epa.gov/emap/
Multi-Resolution Land Characteristics (MRLC) Land Cover
The EPA publishes Multi-Resolution Land Characteristics (MRLC) land cover data.
MRLC data were derived from the classification of Landsat Thematic Mapper satellite imagery
acquired between 1991 and 1993. The data are in grid cell format with a resolution of 30 meters.
The MRLC data are separated into 15 classes: water, low-intensity developed, high-intensity
residential, high-intensity commercial/industrial, hay/pasture, row crops, other grass, evergreen
forest, mixed forest, deciduous forest, woody wetland, emergent herbaceous wetland, and three
classes of bare. A land cover map of the Chesapeake Bay watershed based on the MRLC data
is available at http://www.chesapeakebay.net. Metadata can be viewed at the MRLC web site.

NASA LANDSAT Imagery
The missions of the LANDSAT series are part of NASA's Earth Science Enterprise
(ESE), which is being built to continue the flow of global change information to users worldwide.
Scientists use LANDSAT satellites to gather remotely sensed images of the land surface and
surrounding coastal regions for global change research, regional environmental change studies
and other civil and commercial purposes. LANDSAT 7, the current mission, will provide repetitive,
synoptic coverage of continental surfaces; spectral bands in the visible, near-infrared, short-wave
and thermal infrared regions of the electromagnetic spectrum; spatial resolution of 30 meters (98-
feet); and absolute radiometric calibration. No other current or planned remote sensing system
matches this combination of capabilities. The data from LANDSAT 7 is being distributed under a
cooperative arrangement with the US Geological Survey and can be obtained at:
http://landsat7.usgs.gov/
National Wetlands Inventory Data
National Wetlands Inventory (NWI) data are published by the U.S. Fish and Wildlife
Service. Each data layer comprises the Arial equivalent of one 7.5' quad (1:24,000 scale) map.
The wetlands are classified according to the Cowardin, et al. (1979) wetland classification
scheme. The wetlands are delineated from photo interpretation of aerial photography, mapped
on stable-base copies of 7.5' quad sheet overlays and either manually digitized or scanned. The
dates of photography used are highly variable and range from the early 1970s through the early
1990s. Of the 1,336 7.5' quads that are wholly or partially contained within the Chesapeake Bay
watershed, 1,211 are available, 33 are in the process of being completed and 92 are expected to
be completed by 2001. NWI data can be downloaded in ARC Export or DIG formats via
anonymous FTP. The data are organized by USGS 250K map names, so it is advisable to have
a USGS index book for the state in which desired quads are located in order to find which 250K
directory to access. Metadata are available at the NWI web site. The NWI home page is:

Information Access through the Chesapeake Bay Program-Chesapeake
Information Management System Home page
A major component of the development of the CIMS network has been to establish user
interfaces for information retrieval. The primary user interface is the data users world wide web
browser. Users can search and download databases, summary statistics and indicators, data
documentation, key data management documents and data inventories from several servers via
the CBP-CIMS home page. Using the CBP-CIMS web site, biological monitoring data can be
obtained geographically, chronologically and programmatically. Customized data sets are
generated when a data user submits search criteria (time, geographic location, data type, etc.) to
a monitoring database. Once search results are returned to the user, they can be saved as a
delimited ASCII flat file. Frequently requested data sets also have been provided on an FTP site.
In the future, routine monitoring data will be accessible through the GIS based Bay Atlas web
application. This interface enhancement will allow for geographic and graphical analysis of data
on line. Other CBP databases and data management "tools" (e.g. QA/QC programs,
documentation, and conversion tables and algorithms to calculate indicators) are being added to
the home page server in installments.
CBP-CIMS FTP Access (Point Data Only)
Data users needing complete copies of the living resource point databases and data
documentation files may directly access ASCII flat file versions of these data through anonymous
FTP. The flat files contain the same data available from the searchable databases however, data
is also provided in preselected subsets for immediate download. The subdirectories in

USING MONITORING DATA
Data availability and demand for data access have grown at exponential rates due to the
e>ctensive development of the Internet. The combination of increased data access and new mechanisms
to store and distribute data have radically changed data management. Providing adequate guidance to
data users on correctly handling the databases and interpreting the data is a challenge. Unsatisfactory
results may be due to the use of data that are unsuitable for the analysis, incorrect manipulation of data
sets or incorrect interpretation of the information in a database.
Please read the data documentation files. Before you use data, become aware of the original
objective(s) and sampling design of a study or monitoring program as well as the database structure. The
data documentation files explain the details of sample collection and processing and the structure of the
data files for each study. All of the data documentation sets have been written with the end data user in
mind. They assume that a user has no previous knowledge of the data collection program. The
biological data sets described in this document are typically either from large-scale monitoring programs
or intensive, targeted studies. The Chesapeake Bay monitoring programs and other long-term efforts are
intended to detect changes and/or trends in the status of living resources on a large scale. They were
designed to be used in a wide variety of analyses. These monitoring programs do not have a spatial or
temporal scale fine enough to answer many site or time-specific questions. However, they are useful in
answering complex, Baywide questions. Another portion of the data sets, predominantly the historic data
sets, are targeted studies. These studies were originally designed to answer specific scientific or resource
management questions on a fine scale. Therefore, sampling design, analytical protocol or site selection
criteria may preclude or obscure elements of the data set critical for your analytical questions.
This section provides guidance on how to merge related files from the CBP-CIMS interface and
subsequently work with monitoring data. The Chesapeake Bay Program relational database structures
and formats have been discussed in other sections of this document. Actual field names and attributes
appear in Appendix A and on-line in the individual data set documentation files. A list of possible CBP
field names for biological and living resources data, and their definitions and units, are provided in
Appendix B. Appendix C contains definitions of parameter and look-up codes used in the databases.
In the development of Baywide zooplankton and phytoplankton indicators, it became necessary to
understand the degree of comparability inherent in the data collected and analyzed by different
laboratories. Until that time, a program of regular quality assurance /quality control and split-sample
comparisons were not part of either the phytoplankton or zooplankton long-term monitoring programs. In
1998 a split-sampling project compared results of the Maryland and Virginia mesozooplankton,
microzooplankton and phytoplankton long-term monitoring programs. The various methodologies used
for plankton enumeration had some biases that have serious implications in Bay analysis and are
important for data users to be aware of.
CBP Phytoplankton and Picoplankton Monitoring Data
The Virginia and Maryland files may be combined with no special preparation. The taxon and
event files can be merged by linking on the following fields:

LAYER
The following is a list of known sampling biases and common user errors for these data.
1) The Virginia sample enumeration technique includes a special effort to identify smaller, rare species
below 8 microns in size. Please account for these extra species when combining Maryland and
Virginia data. A list of the rare species is provided in the on-line data set documentation.

1999 Users Guide to CBP Biological and Living Resources Monitoring Data
2) The species Merismopedia and.Agmenellum have been determined to be synonymous. The currently
accepted literature name for this species is Merismopedia., As of January 1999 all programs will
switch to the accepted species name. The Maryland monitoring program has previously used the
Agmenullum name.
3) The Virginia plankton program has a picoplankton enumeration component. The Maryland monitoring
program currently lacks this element. Therefore Maryland has counted organisms as either micro
flagellates or unidentified blue-green spheres that Virginia omits because they are accounted for in
the picoplankton analysis.
a) Maryland counts all visible small green flagellated cells as microflagellates. Virginia includes these
organisms as phytoplankton only if they appear to be autotrophic.
b) Maryland counts all small non-flagellated blue-green spheres as unidentified Microcycstis species.
Virginia omits these organisms from their phytoplankton counts.
4) The Maryland program counts individual cells when blue-green trichomes are observed. The Virginia
program counts only whole trichomes. After January 1999 the Virginia program adapted the
Maryland protocol.
5) Composite samples: It should be noted that the CBP sampling protocol utilizes composite samples.
There are no samples for individual depths.
6) NODC Codes and TSNs: All species were assigned National Oceanographic Data Center, Version 8
(NODC) species codes and permanent Integrated Taxonomic Information System (ITIS) Taxon Serial
Numbers (TSN) where available. The NODC taxonomic code is a hierarchical system of numerical
codes used to represent the scientific names of organisms. The code links the Linnaean system of
biological nomenclature to a numerical schema that facilitates modern methods of computerized data
storage and retrieval. Additionally, each recognized species is given a unique ITIS permanent TSN.
The TSN value does not change regardless of changes in taxonomic classification over time. NODC
codes are not currently being updated.
7) Virginia picoplankton counts: Picoplankton counts are available for Virginia waters only. The data
files are structured the same as for phytoplankton data. The count data are provided in the taxon file
and are identified taxonomically as Autotrophic Picoplankton.
8) Maryland SAMPLE_ NUMBER: Note that the Maryland SAMPLE_NUMBERs are sample identifiers;
they are not synonymous with a replicate number. Please perform a count of SAMPLE_NUMBER
by STATION, SAMPLE_DATE, LAYER and SOURCE to determine the number of replicate samples
taken at a station.

CBP Fluorescence Monitoring Data
The horizontal and vertical files may be used with no special preparation
The following is a list of known sampling biases and common user errors for these data.
1) The Maryland horizontal fluorescence data between 1984 and 1998 (excluding the special Potomac
survey) and all Virginia horizontal fluorescence collected by Old Dominion University between 1991
and 1997 had station latitudes and longitudes estimated through an interpolation process. The
latitudes and longitudes are at best approximations of actual positions in the field. Please see
FORMULAS, CALCULATIONS AND CONVERSIONS in the Data Documentation for detailed
explanation of how the positions were estimated. This method of locating position does not meet
EPA sampling position policy since sampling locations were not measured with a Global Positioning
System (GPS). Inaccuracies in the estimated station locations may be problematic in mapping or
ground truthing applications.
2) Locations for the horizontal Potomac fluorescence, horizontal fluorescence collected by the Virginia
Institute of Marine Sciences, and the Maryland and Virginia Vertical Fluorescence surveys were
determined with Loran-C and should be less problematic.
3) The Maryland Fluorescence data were resubmitted due to errors in the calculation of fluorescence
values. Do not use data with an R_DATE prior to May 31,1995.

The microzooplankton and mesozooplankton taxon files can be merged if the following sample volume
correction is made to the mesozooplankton:
1) The mesozooplankton taxon counts and total counts must be converted to liters before the sets can
be merged. Mesozooplankton counts are reported in organisms per cubic meters. Microzooplankton
counts are reported in organisms per liter. The conversion is:
DEN_M3 71000 = DEN_L
The following is a list of known sampling biases and common user errors for the microzooplankton data.
1) Virginia has used the classical definition of microzooplankton as being zooplankton 20-200 um in
size. Maryland considers barnacle nauplii, polychaete larvae and cladocerans to be mesozooplankton
and does not count any organisms from these groups. These organisms are enumerated in the
Maryland mesozooplankton program. Maryland also counts the non-loricate cilliates and tintinnids
that are less than 20 um in size. The Virginia size cutoffs for tintinnids and non-loricate ciliates are
based on widths while Maryland's size categories are based on length. After January 1999 Virginia
adopted the Maryland method of enumerating all ciliates and does not drop any cilliates from counts
that are less than 20 m in width. The Virginia group of oligotrichs was renamed non-loricate cilliates.
The following table lists the differences between Maryland and Virginia in defining various taxonomic

2) Not paying attention to the life stage column is another common error. These data sets will have
multiple records for the same species that differ by the life stage. An empty life stage column means
the taxon counted were adult organisms.
3) NODC Codes and TSNs: All species were assigned National Oceanographic Data Center, Version 8
(NODC) species codes and permanent Integrated Taxonomic Information System (ITIS) Taxon Serial
Numbers (TSN) where available. The NODC taxonomic code is a hierarchical system of numerical
codes used to represent the scientific names of organisms. The code links the Linnaean system of
biological nomenclature to a numerical schema that facilitates modern methods of computerized data
storage and retrieval. Additionally, each recognized species is given a unique ITIS permanent TSN.
The TSN value does not change regardless of changes in taxonomic classification over time. NODC
codes are not currently being updated.
4) Maryland Microzooplankton SAMPLE_ NUMBER: Note that the Maryland microzooplankton
SAMPLE_NUMBERs are sample identifiers; they are not synonymous with a replicate number.
Please perform a count of SAMPLE_NUMBER by STATION, SAMPLE_DATE, LAYER and SOURCE
to determine the number of replicate samples taken at a station.
5) CBP monitoring program components collect composite samples. There are no samples for individual
depths.
The following is a list of known sampling biases and common user errors for the mesozooplankton data.

4) Prior of 1999 the Coefficient of Variance Separation method (Alden, etal 1982) used by ODU to sieve
mesozooplankton before counting them consistently lost small individuals (e.g. Bosmina) and narrow
individuals (e.g. Acartia copepodites) through the 202 um mesh sieve. Therefore, Virginia counts prior
to 1999 underestimate the actual abundances of many taxa. In 1999 a 64 um sieve was added to
capture the smaller/narrower taxa. Split sampling efforts to confirm the comparability of the Maryland
and Virginia mesozooplankton counts are nearly complete. Please contact the living resources data
manager for details of the split sampling comparisons and final report. The final report will include
correction factors for the pre-1999 Virginia data counts of common species. These correction factors
must be applied before any Baywide analysis is attempted.
5) Between 1989 and 1998, Versar Incorporated ceased macrozooplankton (amphipods, shrimp, etc.).
Also in 1998, In addition, all samples, after the standard hierarchical counting technique, were filtered
through an 850 micrometer sieve. Mesozooplankton that were retained in the 850 micrometer sieve
that were not previously identified in the subsamples and/or macrozooplankton were counted and
identified.
6) The 1998-1999 split sampling results showed some differences in taxonomic identifications between
Maryland and Virginia. These differences will be more thoroughly described in the final report. Please
contact the living resources data manager for details of the split sampling comparisons and final
report.
Known sampling biases and common user errors in using the mesozooplankton and microzooplankton
data in combination include:
1) Copepod nauplii were counted in both the mesozooplankton and microzooplankton samples and are
included in both data sets. The smaller mesh size (<44u) of the net used to collect microzooplankton
samples in Maryland and the whole water sample collection method in Virginia are more efficient in
retaining the smallest copepod nauplii. Therefore, the microzooplankton estimates of copepod nauplii
density are considered by the principal investigators to be more accurate. Remove the copepod
nauplii in the mesozooplankton files prior to merging the micro- and mesozooplankton files.
2) Barnacle nauplii were reported in the Virginia mesozooplankton data from January 1985 through
December 1992. After January 1993 barnacle nauplii were reported only in the microzooplankton
data.
CBP Benthos Monitoring Data
These data sets require merging to be fully functional. The Virginia and Maryland CBP
monitoring programs and the historic files may be combined with no special preparation. There are two
types of sampling event files presented with the benthic monitoring data- the event and biota event files.
The event data files contain records for all sampling events, which have occurred as part of the benthic
monitoring program. This includes all instances where water quality, sediment or biota data were
collected. The biota event files contain only event records for sampling events where biota samples were
analyzed for content. Note: Not all-sampling events had biota data collected or have had the biota

Protocols in the Maryland CBP benthos monitoring program diverge significantly from those in the
Virginia CBP benthos monitoring programs and the historic data sets. The Maryland benthic monitoring
program has changed its criteria for selecting sampling locations several times in the course of the
program, going from fixed sites, to randomly stratified sites, to a mixture of the two. As of January 1996
Virginia also has added a random site selection component to their monitoring program. It is critical to
read the data documentation file before attempting to use either the Maryland or Virginia benthic
monitoring data. Below is a brief outline of the differences between the Maryland and Virginia CBP
programs.
Maryland CBP Benthic Monitoring Program
1) Multiple sampling schemes: fixed stations, sites randomly selected for identified strata and
combination random strata and fixed site sampling. Sampling sites are not associated with any
standard CBP monitoring stations. Analysts must use a geographic mechanism to relate stations
(e.g., CBP Chesapeake Bay segmentation scheme, centroids). A unique station naming convention
was developed to account for the various site selection processes.
2) Multiple sampling gears. Sampling gear artifacts vary in data.
3) Changing sampling frequencies. Sampling frequency varies from 7 to 10 times annually, and occurs
in the spring, summer and fall.
4) Major change in biomass methodology in 1989. (See data documentation.)
5) Chemical analyses performed on sediment samples varied by date.
6) Surface to bottom water column hydro casts were made at each site.
7) Maryland SAMPLE_ NUMBER: Note that the Maryland SAMPLE_NUMBERs are sample identifiers;
they are not synonymous with a replicate number. Please perform a count of SAMPLE_NUMBER
by STATION, SAMPLE_DATE, LAYER and SOURCE to determine the number of replicate samples
taken at a station.
Virginia CBP Benthic Monitoring Program
1) A fixed site sampling scheme was used from 1985-1995. Most of the fixed stations corresponded
with regular CBP monitoring stations. The data, therefore, has direct iocational linkages to plankton,
zooplankton and water quality data sets. In 1996 a random strata component was added to the fixed
site sampling. These sampling sites are not associated with any standard CBP monitoring stations.
Analysts must use a geographic mechanism to relate stations (e.g., CBP Chesapeake Bay
segmentation scheme, centroids). A unique station naming convention was developed to account for
the various site selection processes.

2) One sampling gear used from 1985-1995. Multiple gears were employed after 1995.
3) Sampling was performed quarterly from 1985-1995. After 1995 to present, sampling is conducted
twice a year.
4) Water quality data for bottom of water column only.
5) In 1996 a Sediment Profile Camera Imaging Program was added. Image summary data is available
on-line, actual imagery is available by request from the living resources data manager.
Historic Benthic Data Sets
Most of the historic benthic data sets were "targeted studies". This means they were concentrated
around areas of resource management interest such as power plants and industrial sites. Some of the
studies were meant as baselines to examine the environmental effect of the operation of these facilities
before and after they went operational. Other studies were begun after a power plant or industrial sites
was operational and were designed to determine how much damage had been done to an area. These
studies frequently did not measure all the parameters found in current monitoring data sets and do not
include biomass determinations.
The following is a list of known sampling biases and common user errors for this data.
1) Using either the Maryland or Virginia CBP monitoring data without understanding the use of both
fixed, randomized and hybrid site sampling protocol, adapted in various stages of the program.
2) NODC Codes and TSNs: All species were assigned National Oceanographic Data Center, Version 8
(NODC) species codes and permanent Integrated Taxonomic Information System (ITIS) Taxon Serial
Numbers (TSN) where available. The NODC taxonomic code is a hierarchical system of numerical
codes used to represent the scientific names of organisms. The code links the Linnaean system of
biological nomenclature to a numerical schema that facilitates modern methods of computerized data
storage and retrieval. Additionally, each recognized species is given a unique ITIS permanent TSN.
The TSN value does not change regardless of changes in taxonomic classification over time. NODC
codes are not currently being updated.
3) In the CBP monitoring data, benthic biomass values are determined on a per taxon basis. See
documentation for Maryland methodology changes.

ECOSYSTEM IN DICATORS
Teams of Bay Program scientists and natural resource managers have worked to develop
indicators of Chesapeake Bay ecosystem health. These indicators are calculated using monitoring data
and provide an indication of how well the various biological communities are functioning. The technical
indicators will be used primarily to interpret and communicate monitoring results. Scientists and managers
will find these summaries useful for a quick overview of Chesapeake Bay monitoring data. The indicators
are expected to provide quantitative information on food chain responses to toxic load reductions in the
Chesapeake Bay. Indicators are also potentially useful in ongoing efforts to develop biocriteria and
restoration targets for state waters. There are number of technical indicators for various trophic groups
currently under development or peer review.
The Benthic Index of Biotic Integrity (BIBI)
The Chesapeake Bay Benthic Index of Biotic Integrity (BIBI) initially released in 1997 (Weisberg
et al. 1997) was meant to be a tool for assessing benthic living resource conditions. Since its introduction,
the index has been used in a variety of restoration and habitat targeting efforts (Dalai et al. 1999). The
BIBI makes a good integrator of long-term environmental conditions because benthic organisms have
limited mobility and their responses to stress are well documented. The current indices are both habitat
and seasonally dependent Therefore, data must be selected for time of the year and preclassified for
habitat conditions.
A series of summary statistics or metrics are first calculated for all sites. The current summary
statistics are as follows:
Shannon-Weiner Species Diversity Index
Total Species Abundance
Total Species Biomass
Percent Abundance of Pollution-Indicative Species
Percent Abundance of Pollution-Sensitive Species
Percent Biomass of Pollution-Indicative Species
Percent Biomass of Pollution-Sensitive Species
Percent Abundance of Carnivores and Omnivores
Percent Abundance of Deep Deposit Feeders
(Note that not all metrics are valid for use in all habitat regimes.) Depending on salinity and bottom type
regime, the selected summary statistics are scored on a ranking of 1, 3 or 5. Pristine sites receive a 5,
slightly degraded sites are ranked a 3, while severely degraded sites receive a score of 1. Lastly, the
summary statistics are combined into a single RGI value for the benthic community at each site by
averaging the scored index metrics.
Data Preparation:
Generally speaking for the Chesapeake Bay, benthic monitoring data in mainstem and tidal tributaries of
Maryland and Virginia are comparable. While there have been major differences in sampling site
selection over the course of the program, there have not been major differences in how samples have
been collected or analyzed. Therefore, the data can be combined for Baywide status and trend work with
few caveats.
33
Indicators
-------
1999 Users Guide to CBP Biological and Living Resources Monitoring Data -
Seasonal selection:
The current BIBI and RGI are summertime indices. For purposes of calculating the B-IBI, summer is
defined as July 15 - September 30. Therefore, part of the first step in all data selection procedures is to
select data for sampling events occurring during the summer period.
Determine Habitat Areas:
Benthic communities differ significantly according to habitat. Therefore, indices and goals were designed
to be calculated by habitat area. The major factors affecting the compositions of benthic communities in
the Chesapeake Bay are salinity and sediment composition. For these indices the classic Venice System
is slightly modified for salinity classification. Sediments are classified by the silt-sand content. Sediments
having less than 40 percent silt-clay content are defined as sand. Sediments with greater than a 40
percent silt-clay content are considered mud habitats.
Bottom Type Classification:
Habitat is determined by a long-term average of the data collected concurrently with the biological
sample.
Step 1) Data are extracted from the SEDIMENT_TABLE for the parameter SILT_CLAY content.
Step 2) For each station an arithmetic mean SILT_CLAY content value is determined.
Step 3) AH stations are classified for sediment content based on the resulting average SILT_CLAY
values. All sites with an average SILT_CLAY value of less than 41 percent are classified as a sand (S)
habitat. All other sites are classified as mud (M) habitats.
0-40 % Silt-Clay
>40 % Silt-Clay
Sand
Mud
Table 5. Sediment Classification System
Salinity Type Classification:
In the calculation module of the CBP benthic database, habitat is classified by a long-term average of all
available salinity data collected concurrently with the biological sample.
Step 1) Data are extracted from the WATER_QUALITY_TABLE for the parameter SALINITY where
SAMPLE_DEPTH is equivalent to station TOTAL_DEPTH.
Step 2) For each Station a arithmetic mean SALINITY content value is determined.
Step 3) All stations have their average AVERAGE_SALINITY values classified based on the ranges.

Combining the Habitat Type Classification:
In the next stage of the CBP benthic database, bottom habitat is grouped into seven major habitat
classifications based on the combination of salinity and sediment classes. The currently used bottom
habitat classes are as follows:
*Tidal Fresh Sand and Mud
Low Mesohaline Sand and Mud
*Oligohaline Sand and Mud
High Mesohaline Sand
Polyhaline Sand
High Mesohaline Mud
Polyhaline Mud
Table 7- Benthic Index of Biotic Integrity Habitat Classifications
NOTE: The current BIBI and RGI technique were found to be most accurate in high salinity areas and
decreasing in value as salinity decreases. It is not recommended to calculate these indices for oligohaline
and tidal fresh water areas even though the published protocol does provide metrics and scoring criteria
for these regions.
Taxon equilibration:
These indices are based on observations about fauna that indicate current benthic conditions. All
data sets must be standardized by applying uniform taxonomic identifications to the data. Eliminate taxa
not sampled quantitatively or taxa groups not truly indicative of benthic conditions. Such groups include
algae, vertebrates (fish larvae), pelagic invertebrates and epifauna. See Table 8 for the list of currently
omitted Epifaunal species (For More Details See- Chesapeake Bay Benthic Community Restoration
Goals, 1994- Appendix B). Also eliminate any fragments or juvenile organisms from the counts.
Summary Statistics:
Calculate Total Species Abundance:
The metric of total species abundance is calculated by a computing a simple arithmetic mean of the total
normalized species abundance.
Step 1) Calculate the number of organisms present in each sample normalizing the number or organisms
to number of organisms per meter squared of surface area.
Step 2) Sum the corrected total abundance of all organisms by STATION and SAMPLE_DATE.
Step 3) Divide the grand sum of species abundance by the total count of SAMPLE_NUMBER (or number
of replicate samples taken per station on a given date.

^
Step 3) Sum the corrected total abundance of carnivores and omnivores by STATION SAMPLE DATE
and SAMPLE_NUMBER. The current list of assigned feeding guilds is given in Table 15.
Step 4) Divide the sum of carnivore and omnivore taxa abundance by the sum of total species abundance
by STATION, SAMPLE_DATE and SAMPLE_NUMBER to determine the percent PI abundance by
replicate. *
Step 5) Sum all of the percentages by STATION and SAMPLE_DATE.
Step 6) Divide the grand sum of carnivore and omnivore abundance percentages by the total count of
SAMPLE_NUMBER (or number of replicate samples taken per STATION on a given SAMPLE DATE)
and multiply by 100 to get a final percentage.
Percent Abundance of Deep Deposit Feeders:
The Percent Abundance of Deep Deposit Feeders is computed by summing total abundance and total
abundance of deep deposit feeding taxa and determines a simple percentage.
Step 1) Calculate the number of organisms present in each sample normalizing the number or organisms
to number of organisms per meter squared of surface area.
Step 2) Sum the corrected total abundance of all organisms by STATION, SAMPLE_DATE, and
SAMPLE_NUMBER (replicate number if applicable).
Step 3) Sum the corrected total abundance of deep deposit feeders by STATION, SAMPLE_DATE and
SAMPLE_NUMBER. The current list of assigned feeding guilds is given in Table 15.
Step 4) Divide the Deep Deposit Feeding taxa abundance by the sum of Total species abundance by
STATION, SAMPLE_DATE and SAMPLE_NUMBER to determine the percent PI abundance by replicate.
Step 5) Sum all of the percentages by STATION and SAMPLE_DATE.
Step 6) Divide the grand sum of deep deposit feeders abundance percentages by the total count of
SAMPLE_NUMBER (or number of replicate samples taken per STATION on a given SAMPLE_DATE ),
and multiply by 100 to get a final percentage.
Scoring the Results:
Scoring the summary statistics to calculate BIBI values can be done in one of two ways: 1) by
comparing sites of unknown quality to reference sites or benchmarks or 2) comparing scoring sites
based on established benchmarks for an estuarine system. Benchmarks or" Restoration Goals" for the
Chesapeake Bay were initially established in 1997 by the site comparison procedure. Monitoring data are
now measured against these goals to determine progress.
Scoring by Reference Sites:
Reference sites are the unimpacted or least-impacted sites within a habitat type. They are used
as a basis for comparison. In the establishment of the current index, reference sites were site that
showed no chemical contaminant impact or significant low oxygen events. (For more details see-
Chesapeake BayBenthic Community Restoration Goals, 1994 and Weisberg et al. 1997)

A value of 5 is assigned to a site whose conditions approximate reference sites, a score of 3 is
given to sites that slightly deviate from reference conditions. A value of 1 is assigned for sites deviating
greatly from the reference site conditions. The values for each of the above metrics are then compared to
the values for the reference site by habitat area with the Kolmogorov-Smirnov test. Threshold values
were established as the 5th and 50th median percentile value for the Shannon-Weiner species diversity
index, abundance of pollution indicative taxa and abundance of pollution sensitive taxa. Total abundance
and biomass respond biomodally and are scored on the bimodal scale. Values of 95 percent were scored
as 1, greater than 5 but less than 95 percent were scored as 3 and values greater than 25 but less than
75 percent were scored as 5.
Table 11. Benthic Index of Biotic Integrity Scoring Percentiles
Not all summary statistics are valid for use in all habitat areas see Table 13 for complete listing of
appropriate metric usage.
Scoring by Reference Benchmarks:
Scoring metrics with respect to established benchmarks (Weisberg et al. 1997) is the protocol
used in the BIBI values in the CBP-CIMS benthic database. The metrics are currently scored based on
appropriate usage in habitat areas (Table 13) and value ranges (Table 14).
Calculating the Benthic Restoration Goal:
To determine if a site's benthic community meets the benthic restoration goal, each metric is first
compared to established benchmarks (Table 12) and scored. The mean value of the scored metrics is
then calculated. If the mean value is equal to or greater than 3, the site meets the restoration goal. An
overall score or BRGI values can then calculated by deriving a mean value for the individual BIBI values
available. All sites with BRGI values of 3 or greater are considered to have met minimum restoration goal.
Values of less than 3 are further broken down into categories of marginally degraded and severely
degraded (Table 14).

APPENDIX B - B IOLOGICAL AND LIVING RESOURCES
DATA DICTIONARY
December 1999
This data dictionary is the source of terms used in defining data in the CIMS living resources and
biological databases. Its purpose is to provide consistency within the CIMS databases by making
data submittal and retrieval compatible among institutions that participate in the program. This
dictionary will be expanded as new parameter and field names are required. Institutions
submitting data to the CBP monitoring database should use these variable names whenever
possible so that names and units of measure are consistent within the CBP monitoring database.
Some of the terms in this dictionary will be subject to change as the Chesapeake Bay Information
Management System implements data dictionary consolidation among monitoring programs.
Each entry in this appendix lists the dictionary term name, a brief term description, and whether a
term is an attribute or value in as attribute field, a data type and field length.

Table C-3. Original Chesapeake Bay Program Segment Designation (CB SEG85).
As part of the geographic referencing of stations, each station is described with a CBP segment
code describing in which segment a station is located. It is based upon the original 1985
segmentation scheme. Due to controversy about the segmentation systems, these codes were
modified for the 1997 CBP nutrient reevaluation (CB_SEG87) and again for better representation
of living resources in 1998 (CB_SEG98). The currently accepted CB_SEG85 values and
descriptions are as follows:

Table C-4. The 1998 Chesapeake Bay Program Segment Designation (CB SEG98>.
AS part of the geographic referencing of stations, each station is described with a CBP segment
SDOC 'ng 'n Which Se9ment a Cation is located. Due to controversy about the original
(Ub_SEG85) and 97 Nutrient Reevaluation (CB_SEG97) segmentation systems, these codes
were modified for better representation of Living Resources in late 1998 (CB_SEG98). Segment
names did not differ from CB_SEG97 however boundaries were modified. Contact a Living
Resources GIS Specialist for details

Table C-19. NOAA Species Code (NODCCODE) and ITIS Taxon Serial Numbers (TSN).
CIMS databases uses the Interagency Taxonomic Identification System (ITIS) Taxon Serial
Numbers (TSN) for species identification within the database. For species with no TSN values,
temporary Chesapeake Bay TSN is generated until a species can be submitted to ITIS for
recognition. The use of the standardized TSN codes among all Bay Program databases will
allows for queries by species from multiple state and national biological databases.
TSN: Each species has been given its ITIS TSN. The ITIS is a partnership of federal agencies
working to improve the organization of, and access to, standardized nomenclature. As part of this
system a national, easily accessible database with reliable information on species names and
their hierarchical classification has been established. The database is reviewed periodically to
ensure high quality with valid classifications, revisions and additions of newly described species.
As part of this effort all Federal agencies have been asked to adopt the use of TSN codes which
assign each recognized species a permanent number. The TSN allows a species to be tracked
over time regardless of changes in name and taxonomic classification. TSN also provides a
uniform key field for database development and species identification across multiple
organizations. When used in conjunction with the NODC, the TSN overcomes the problem of
numeric changes in the NODC code whenever species are reclassified.
Temporary codes are assigned to taxa that are recognized in the scientific literature but have not
been assigned an NODC code and a TSN. The value BAYXXXX has been assigned to all taxa
without TSN. A temporary NODC code is developed for each unassigned taxon based on its
known taxonomy and its species name. For example, the beginning couplets of the NODC code
which reflect the known phylogeny of an unassigned taxon are combined with letters from its
species name to form a temporary code.
NODC CODE: All species on the list have been assigned at least partial National
Oceanographic Data Center (NODC) Taxon Codes (Version 8.0). The NODC Taxon Code is a
hierarchical system of numerical codes used to represent the scientific names and phylogeny of
organisms. The code links the Linnaean system of biological nomenclature to a numerical
schema that facilitates modem methods of computerized data storage and retrieval. An NODC
code contains a maximum of 12 digits partitioned into two-digit couplets. Each couplet represents
one or more levels of the taxonomic hierarchy. For example,
Digit Represents
1-2 Phylum
3-4 Class and/or Order
5-6 Family
7-8 Genus
9-10 Species
11-12 Subspecies
Codes and Lookup Tables 92
-------
The 1999 Users Guide to CBP Biological and Living Resources Monitoring Data
One drawback of the NODC code is that a code will changes over time to reflect current changes
in taxonomic classifications. However, it provides data analysts with a very useful tool for sorting
organisms into taxonomic groups.

The 1999 Users Guide to CBP Biological and Living Resources Monitoring Data
CBP Guidelines and Policies
This section discusses the guidelines and policies that must be followed by all agencies
participating in data and information collection, processing and submittal to the Chesapeake Bay
Program. This includes not only the agencies contracted for CBP work, but also any agency that
the contracting agency has involved in these activities. The CBP has adopted these guidelines
and policies in order to improve coordination, compatibility, standardization and information
access throughout the Program. In addition to these guidelines and policies, any activities funded
with federal government funds, must also adhere to applicable Federal Information Processing
Standards (FIPS) (http://www.itl.nist.gov/div897/pubs/).
Deliverables
Grantees and contractors are required to submit deliverables in electronic format, whether or not
this requirement is specified in the grant or contract. Electronic deliverables include reports,
graphics, spreadsheets, imagery, data files, audio and digital video products. Deliverables must
be submitted on time as specified in the grant or contract. All data and information funded by CBP
agencies, whether direct CBP funding or indirect (matching funds), are the property of the CBP.
All data and information funded directly or indirectly by the CBP is public information and shall be
made available to the public, unless there is a grant or contract condition that specifies otherwise.
In addition, source data that are collected and processed in the creation of a deliverable should
also be submitted, if practical. Final details about how data and information must be submitted
must be arranged with the CBP Grant or Contract Officer.
Deliverable text is preferred in WordPerfect 6.1 format. Microsoft Word or PageMaker formats are
also acceptable, depending on the product. Graphic images for reports are preferred as TIF
format. Images for web publication are preferred as GIF or JPEG format. GIS files are preferred
as ARC/INFO noncompressed export (.EDO) or ArcView (shape) formats. All deliverables must
have companion metadata.
Locational Data Policy
The CBP adheres to the EPA's locational data policy which requires consistent use of
latitude/longitude coordinates to identify the location of entities. All data, containing spatial and/or
specific geographic locations, collected or assembled under a grant or contract vehicle, for use by
the CBP, or to be served on the Internet via the Chesapeake Information Management System
(CIMS), must have latitude and longitude information for each entity. Projects not creating or
reporting spatial data, but confined to a given project location(s), shall include the
latitude/longitude of the location(s) within the study/final report.
In accordance with CBP locational data policy, data generators/servers and grant/contract
recipients agree to ensure that latitude and longitude coordinates (given in degrees and decimal
degrees) are provided for all sites for which data are collected and are accurate to the level
required for the purpose of the application of the data. Field measured locations shall be accurate
to the best practical geographic positioning method. Currently, Differential Global Positioning
System (GPS) equipment can reliably provide locational coordinates accurate to within 10-25
meters (5 decimal places in decimal degrees), and is the preferred method of point location
determination. Applications such as station monitoring locations should provide locational data
with accuracy to that level. Other applications, such as digitizing points or watershed boundaries
from mylar-media maps, cannot provide accuracy better than that of the original map, and can not
match the accuracy of GPS or surveyed locations. Remote sensing platforms can now collect
sub-meter resolution data (6 decimal places in decimal degrees). Therefore, it is required that

-------
The 1999 Users Guide to CBP Biological and Living Resources Monitoring Data
metadata be provided for all data and must include a measurement of the accuracy of the
coordinates and the original source material and methods for obtaining the coordinates. Use of
the draft EPA "MAD" (Method. Accuracy, Description) (Appendix A) codes to document the
locational accuracy of an entity (e.g., outfall, station, watershed boundary) is recommended. It is
the responsibility of data generators/providers to provide coordinates accurate to the level that is
practical for the intended application and to document the accuracy of those coordinates.
The data generator/provider/server further agrees to document, in writing, that locational data
were derived using an approved method and recorded in accordance with federal regulations and
other EPA requirements, noted in the "Authorities" section of the EPA's policy. Grantees shall
include in their application an assurance to comply with this requirement. Contractors must
comply with this requirement, and the contract workplan must include a discussion of the method
for complying with this requirement.
Map Coordinate Datum Policy
The CBP has adopted the policy that all data generated or collected for, submitted to the CBP or
served on the Internet via CIMS shall utilize the North American Datum 1983 (NAD83) horizontal
reference and the North American Vertical Datum 1988 (NAVD88) vertical reference. Most likely,
organizations have been using NAD27 horizontal reference since USGS maps were historically
created using this reference. The requirement to use NAD83 will require conversion of latitudes
and longitudes using NAD27 to NAD83. Metadata reporting requires specification of the
horizontal and vertical datum where applicable.
Map Coordinate Projection Guidelines
The CBP has adopted the policy that the standard projection for geographic information system
(GIS) files maintained at the CBPO shall be UTM Zone 18 (meters) for all data within the
Chesapeake Bay Basin. For larger or national GIS data files, the standard projection for GIS files
maintained at the CBPO shall be Albers Conical Equal Area (meters). This policy was established
to provide consistency in computing distance and area calculations, map shapes, and to facilitate
database design and maintenance, and based on the recommendation of USGS. GIS and data
files containing spatial data, must have coordinates reported as latitude and longitude (decimal
degrees) as per the Locational Data Policy. Ideally, it is requested that information containing
projected coordinates, also report coordinates in UTM Zone 18. GIS files submitted to the
Program or served by CIMS participants, are preferred in ARC/INFO noncompressed export or
ArcView Shape format for compatibility with the majority of the Chesapeake Bay Program GIS
databases. Partner organizations who have historically maintained GIS files in another projection
or coordinate system are exempt from this policy (unless they are developing or providing data
products as part of a Bay Program initiative) since the effort to convert large historical holdings
would be prohibitive.
Metadata Policy
The CBP has adopted the policy, consistent with Presidential Executive Order #12906, that all
data generated or collected using federal funds, submitted to the Chesapeake Bay Program, or
served on the Internet via CIMS, shall be accompanied by metadata (descriptive information
about the data, often referred to as documentation) that fully conforms to the Federal Geographic
Data Committee's requirements for metadata. Metadata created for CBP shall also be delivered
to the EPA or another federal clearinghouse as a requirement to fulfilling this policy and related
grant or contract conditions. The FGDC guide for creating metadata is the Content Standards for
Digital Geospatial Metadata Workbook (http://www. mews.org/nsdiAffdocuments).
Submitters' Guidelines 118
-------
The 1999 Users Guide to CBP Biological and Living Resources Monitoring Data
The CBP also has adopted the policy -that all data generated or collected using federal funds,
submitted to the CBP or served on the Internet via CIMS, shall adhere to the National Biological
information Infrastructure's (NBII) Metadata Standard, where applicable. The NBII Metadata
btandard, popular for environmental programs, provides extensions to the FGDC Metadata
Standard for documenting biological data and information. Currently this standard, the Draft
Content Standard for National Biological Information Infrastructure Metadata, is in draft form
(http://www.nbs.gov/nbii/non-spatial.html). FGDC is reviewing how these and other extensions
can be added to the FGDC standard so that the standard is useful to a larger user population.
Chemistry extensions would also be quite useful for CBP use.
Data to be accessed on the Internet via CIMS must follow the CIMS Metadata Reporting
Guidelines established by the CBP. These guidelines were established to facilitate entering
consistent, accurate metadata to ensure the information about the Chesapeake Bay will be easily
available, and used appropriately. The CIMS Metadata Reporting Guidelines also accessible on
the CIMS Internet web page.
Common Station Names Guidelines
The CBP has adopted the guideline that all data generated or collected for, submitted to the CBP
or served on the Internet via CIMS, should use a consistent set of common station names for
identifying and reporting monitoring station locations. It is the data provider's responsibility to
comply with this guideline. The purpose of this guideline is to create a master table of station
names, to the extent possible, to reduce confusion among cooperating agencies. The station
names table, maintained on the CBP web site, should serve as the master list. Updates to this
table that are required by data submitters shall be coordinated with the CIMS Technical
Information Access Team to maintain a consistent stations names list.
Common Data Dictionary Guidelines
The CBP has adopted the guideline that all data generated or collected for, submitted to the CBP
or served on the Internet via CIMS should use the CBP common data dictionary for defining all
data elements and units of measure. It is the data provider's responsibility to comply with this
policy. The purpose of this guideline is to create one data dictionary, to the extent possible, to
reduce confusion among cooperating agencies. Updates required by data submitters to the
dictionary shall be coordinated with the CIMS Technical Information Access Team to maintain
one consistent data dictionary.
Common Database Design Guidelines
The Chesapeake Bay Program has adopted the guideline that all data generated or collected for,
submitted to the Chesapeake Bay Program, or served on the Internet via CIMS should utilize the
CBP common database design for managing data. It is the data provider's responsibility to
comply with this guideline. Its purpose is to use common database designs, to the extent
possible, to simplify data formatting and sharing. Modifications to the common database design
shall be coordinated with the CIMS Technical Information Access Team to maintain consistency
in the database structure. If the CBP agencies do not have a pre-defined database that is
acceptable for the work being conducted, the grantee/contractor should work with the funding
agency to develop a database design that suits the requirements of the work, while maintaining
maximum compatibility with other CBP database designs.

The 1999 Users Guide to CBP Biological and Living Resources Monitoring Data
Calendar Date Policy
The CBP has adopted the standard that all data generated or collected for, submitted to the CBP
or served on the Internet via CIMS should adhere to the Federal Information Processing
Standard, Representation for Calendar Date and Ordinal Date for Information Interchange (FIPS
PUB 4-1).
This standard states, "For purposes of electronic data interchange in any recorded form among
U.S. government agencies, National Institute of Standards and Technology (NIST) highly
recommends that four-digit year elements be used." The year should encompass a two-digit
century that precedes, and is contiguous with, a two-digit year-of-century (e.g., 1999, 2000, etc.).
In addition, optional two-digit year time elements specified in ANSI X3.30-1985(R1991) should
not be used for the purposes of any data interchange among U.S. government agencies.
Therefore, it is required to report and store all dates using four digits for the year. In addition to
facilitating data sharing, this requirement reduces the complications of processing date data after
the millennium rollover at year 2000.
Common Method Codes Guidelines
The CBP has adopted the guideline that all data generated or collected for, submitted to the CBP
or served on the Internet via CIMS should utilize the CBP Method Codes tables, which are
defined in the Guide to using CBP Water Quality Monitoring Data and The 2000 Users Guide to
CBP Biological and Living Resources Monitoring Data, as well as in the actual CBP relational
database tables. It is the data provider's responsibility to comply with this guideline. Its purpose is
to use standardized method codes, to the extent possible, to simplify data coding and sharing.
The methods used by monitoring agencies and analytical laboratories are critical in providing
accurate measurements. Knowing the field and laboratory methods used is critical during analysis
and reporting, therefore capturing the methods is a high priority during database development.
Modifications to the CBP Method Codes shall be coordinated with the CIMS Technical
Information Access Team to maintain consistency in the table contents. If CBP agencies do not
have a pre-defined method code that is acceptable for the work being conducted, the
grantee/contractor should work with the funding agency to develop method codes that suits the
requirements of the work, while maintaining maximum compatibility with other CBP codes.
Numeric Data Reporting Guidelines
The CBP has adopted the guideline that all data generated or collected for, submitted to the CBP
or served on the Internet via CIMS should report numeric data elements at the same level of
precision as that of the original measurement. The exact precision of recorded values must be
maintained. This guideline has a significant impact on data analysis and the decisions made
based on these analyses.
Values should not be zero-filled to greater precision than actually recorded. For instance, if the
measured value is 0.03, then the reported value should be 0.03 and not 0.030, which would imply
precision to the third decimal place. For values that are recorded as below or above detection, a
detection flag (in a separate data field) shall be used to identify the value as below or above the
detection limit of the method, and the value shall be reported as the detectable limit. Values
should be reported as zero, only if the measured or recorded value is zero. Values that are
missing shall be reported as missing or null or nil, to identify values that were sampled but where
no value was obtained. Missing, null, or nil values are different than those that were never
sampled, which should be recorded as a blank field, if they are recorded at all. It is the
Submitters'Guidelines 120
-------
The 1999 Users Guide to CBP Biological and Living Resources Monitoring Data
responsibility of the data submitter to record in the metadata, how measurements are coded, as
well as the accuracy of the measurements.
It is important to note that some software tools used in data processing may represent the data
internally with more precision than the original measurement, and/or may round the value. For
instance, even though a value of 0.3 was entered, the value may be stored and reported as
0.299999.
Taxonomic Data Reporting Guidelines
The CBP recognizes that access to consistent, scientifically credible taxonomic information is
essential to many Program activities. The CIMS Technical Information Team recognizes that the
National Integrated Taxonomic Information System (ITIS) program is best equipped to provide
this kind of taxonomic standardization and support. ITIS is a partnership of federal agencies
formed to satisfy their mutual needs for scientifically credible taxonomic information. ITIS
provides taxonomic data and a directory of taxonomic expertise that will organize and provide
access to, standardized nomenclature support a national taxonomic inventory system. Therefore,
in order to facilitate the need for uniform quality taxonomic information exchange within the
Chesapeake Bay Program and other national programs, the ITIS Standards have been adopted.
Therefore the CBP requires that data submitters and CIMS partners serving data on the Internet
should utilize the ITIS TSNs for species identification. Detailed information about ITIS and
access to its taxonomic database can be found at URL:
http://www.itis.usda.gov/plantproj/itis/index.html .

Background
This document is one of several CBP products designed to implement the
management goals set forth in the Living Resources Monitoring Plan (Chesapeake
Bay Program Agreement Commitment Report, July 1988) and adopted by the
Executive Council. As catted for in the 1987 Chesapeake Bay Agreement, the
plan provides a framework for a baywide, living resources monitoring program
based on existing programs. The plan was viewed as one step towards the goal of
fully integrating living resources, habitat and water quality monitoring.
The plan specifically charges the CBP with instituting a data
management and reporting system for the living resources monitoring program.
The system would build on the facilities of the existing CBP Computer Center
and ultimately provide:
* A large quantity of consistent data of known quality, in standardized formats
and structures;
4 Ready access to the data for analytical and reporting purposes; and
4 thorough data documentation.
The plan recognizes that monitoring programs cannot achieve their
ultimate goals of providing information to the Bay community and serving the
restoration and management of the Bay if their data are inaccessible, poorly
managed, inadequately documented or not analyzed or reported in a timely
manner.
In response to the charge, and to a restructuring of the Bay Program
Computer Center in 1993, the Living Resources Subcommittee hired three staff
persons to continue implementing a data management and reporting system for
biological and living resources monitoring data. These staff are responsible for:
creating, maintaining and updating key databases and CIS coverages; facilitating
use of the databases and coverages and providing data analysis support to the
Living Resources Subcommittee and other CBP participants. Contact the Living
Resources Subcommittee coordinator at 1-800-YOURBAYfor more information.
