     The U.S. Environmental Protection Agency is pleased to present you
an account of our research and management projects presently underway in
the Chesapeake Bay Program.  This report covers currently funded projects
that are being conducted for the period from October 1, 1977 through
October 15, 1981 and should guide the reader to a better understanding of our
program.  "The Chesapeake Bay Program - Project Summaries" is written in
nontechnical terms for the general public; it is designed to give the reader
an overview of the steps being taken by the CBP to identify and resolve some
of the Bay's water quality problems.
     The report begins with an introductory statement on program authority,
funding, organizational structure, objectives and study areas.  General
information on seven study areas follows.  Specific features of all ongoing
research projects in each study area, including basic objectives, scientific
approach and expected products,  comprise the main body of the text.  Should
you desire more detailed information on any of these projects, please contact
the Project Officer cited in the report.
     Any study program of this complex a nature requires the help and coopera-
tion of the public, Bay users, governmental (Federal, state and local) and
scientific communities.  We are fortunate to be working in an environment
         <*•
where these diverse sectors are pulling together to achieve a common goal —
a better Bay for present as well as future generations.  The time and effort
they have given is greatly appreciated.

                               INTRODUCTION







     The Chesapeake Bay, one of the largest estuarine systems in the world,




encompasses some 7,000 miles of shoreline and a surface area of about




4,300 square miles.  The Bay receives its major freshwater input from the




Susquehanna, Patuxent, Potomac, James and Rappahannock Rivers.  It serves as




a recreational resource, home for oysters, crabs and fish, a source for




minerals and cooling waters, a channel or transportation link and a natural




assimiliative sink for waste disposal.




     Recognizing that the Chesapeake Bay is a unique and fragile national




resource subject to heightened competition among potential users as Bay-area




populations continue to expand rapidly, the 94th Congress authorized EPA




to conduct an indepth study of the Chesapeake Bay to assess the principal




factors having adverse impacts on its environmental quality and to direct and




coordinate a program of research and abatement that will, efficiently address




those factors.




     EPA implemented this initiative through the Chesapeake Bay Program (CBP)




which is focused upon (1) identifying and improving governmental coordination




and participation, (2) coordinating pollution research to identify source,




transport, fate, physical properties and control alternatives, (3) developing




and maintaining a two-way dialogue with the Bay public to assure that the




Government is responsive to the interests of the citizens, and (4) directing




all phases of data management from collection through analysis and information




dissemination.




                                      1

-------
     In keeping with the traditional partnership atmosphere that has character-

ized the GBP from its outset,  EPA and representatives from the State Water

Control Board in Virginia and  the Water Resources Administration in Maryland,

along with Bay area citizens,  met during October 1977 for a 3-day workshop to

define the future research areas for the Program.  The purpose was to identify

Bay-area environmental problems and define a management structure for the Bay

Program that ensured the continued and full involvement of the State agencies

and the public throughout all  phases of the Program.

     The significant products  of that intensive workshop were:  (1) the

identification of 10 problem areas threatening the environmental health of

the Chesapeake Bay, and (2) the definition of a management structure that

includes EPA, State personnel  and interested citizens on a hierarchical

series of committees and work groups that range from policy setting to

working staff level arrangements.

     In the technical program areas, 10 major study areas were identified:



     (1)  High Priority

          (a)  Toxics
          (b)  Eutrophication
          (c)  Submerged Aquatic Vegetation

     (2)  Medium Priority

          (a)  Shellfish Bed Closure
          (b)  Fisheries Modification
          (c)  Dredging and Spoil Disposal
          (d)  Hydrologic Modifications

     (3)  Low Priority

          (a)  Wetlands Alteration
          (b)  Shoreline Erosion
          (c)  Water Quality Effects of Boating and Shipping.

-------
     Because of funding limitations, the Program has, to date, focused upon




the high priority areas.  They are described in more detail in the body of




the text.  In addition to the program areas outlined, the separate category




of data management was funded to provide information storage/retrieval




services for all aspects of the Program.

TOXICS PROJECTS

-------
                            TOXICS PROGRAM  AREA








     Toxic  substances represent an obvious  threat to the stability and




continued use of Chesapeake Bay resources.  Recognition of the role of




toxics in the ecological health of the Bay  system requires a thorough




understanding of the chemical, physical, and biotic dynamics that form the




total estuarine system.  Definitive information on sources, pathways, and




fate of toxic substances is scarce, and where available, is usually limited




to specialized problems in restricted areas.  The Chesapeake Bay Program is




filling this information gap by studying toxic substances from industrial,




agricultural and aerial sources and their behavior within the estuarine




system.




     Accumulation of toxics in food chains  and the potential health/economic




effects are a primary concern.  The toxics  study effort is addressing this




concern by developing a baseline inventory  of the abundance and distribution




of toxics in the sediments, pore water, water column, and biota.  Comprehensive




research tasks are being conducted to assess both natural and anthropogenic




sources of toxic chemicals in sediments, water, and biota and to determine




their rates of transport and transformation within the Chesapeake Bay




system.  Identified problem areas will receive intensive investigation, and




study results will serve to delineate management options to reduce environ-




mental hazards.

OBJECTIVES:
     This is a companion project  of work being performed by the Virginia
Institute for Marine Science  for  Virginia waters under grant number R806001
(page 22).  This project has  three objectives:  (1) determining the distribu-
tion and physical properties  of Bay sediments, (2) identifying sites of
erosion and deposition in the Upper Bay, and  (3) developing a total sediment
budget for the Bay.  This study is concerned  with the Maryland portion of the
Chesapeake Bay, and also provides a coordinating base for other Maryland
Geological Survey efforts in  the  Toxics Program.


SCIENTIFIC APPROACH:
     Surficial sediment  samples are collected from a 1 kilometer grid
network that spans the Maryland portion of the Bay.  These samples are
analyzed for various  physical, chemical and mineralogical characteristics.
The field program is  separated into two simultaneous operations:  nearshore
(water depths less than  3 meters), and offshore (water depths in excess of
3 meters).

     Comparisons between historical and contemporary bathymetric data for
this portion of the Bay  will  help identify areas of erosion/deposition by
mapping changes in water depth due to accumulation/removal of material.


PRODUCTS:
     Study products include  baseline mapping of sediment features, mapping
of erosional/depositional  patterns, and a total sediment budget for the
Bay.  Detailed features  will be  plotted at a scale of 1:20,000; regional
effects will be plotted  at a scale of  1:40,000.  Support documentation will
be available in both tabulated and computer-compatible forms.

    Share	  14,361
  TOTAL	$158,126
OBJECTIVES:
     This  project  seeks to perform a geochemical survey of  sediments  in
select portions  of  the Chesapeake Bay that will:  (1)  establish  the present
trace metal composition of Bay sediments, (2) allow estimation of  the deposi-
tional flux of individual trace metals to the Bay bottom, and  (3)  permit
compilation of an  improved trace metal mass balance.


SCIENTIFIC APPROACH:
     Samples of  surficial bottom sediment are secured along approximately
15 east-west traverses  spaced equally along the entirety of the  Bay.   The
resulting sample set  is analyzed for trace metal content via atomic absorption
spectrometry.  Quality  assurance techniques will reference all measurements
to the National  Bureau  of Standards industrial river sediment standard.

     About 15 sediment  cores from selected stations throughout the Bay will
be analyzed by Pb£lO  deposition rate determinations.  Vertical profiles  of
trace elements are  determined by plasma emission spectroscopy.  These  data
allow a cross-check of  surface sediment analysis and also serve  to establish
historical changes  in the profile.

     The bulk of sample collection is performed by the Maryland  Geological
Survey, grant number  R805965 (page 21) and the Virginia Institute of Marine
Science, grant number R806001 (page 22).


 PRODUCTS:
     Final products  of  this  study include maps depicting the present chemical
quality of Bay sediments with respect to selected trace metals;  a report
will discuss trace metal sources, transport and sinks in the light of experi-
mental findings.

 OBJECTIVES:
     The objective is to provide analytical data to assist in determining
the concentrations of up to 12 trace  elements in the waters of the Bay.


 SCIENTIFIC  APPROACH;
     Several methodologies (graphite  furnace atomic absorption, isotope
dilution spark source spectrometry, neutron activation analysis) will be
used to identify and quantitate a variety of elements.  Collection of samples
is on a regular 1 kilometer grid covering the entire Bay.  Grid locations and
dates of sampling are coordinated with  sampling operations of other projects
to obtain data of maximum value in developing a model of the Bay.  At each
location both top and bottom samples  will be taken and filtered to give
suspended particulate and dissolved metal samples.  In addition discharges
into the Bay from the Potomac and Rappahannock Rivers will be sampled to
provide data on sources  and amounts of metals entering the Bay.

     The elements chosen for initial  work are copper, lead, zinc, cadmium,
manganese,  molybdenum, nickel,  chromium, tin, mercury, arsenic and selenium.

     Additional samples  will be collected at each site for storage in a
sample bank.


 PRODUCTS:
     Products include  data  on  the concentrations of 12 key trace elements  on
the top and bottom  of  the water column at precisely defined locations in the
Bay.

OBJECTIVES;
     The objective of this  project  is to establish a system to detect,
identify, and quantify toxic  organic compounds of significance in the water
column, :n sediments, and in  mollusk tissues from the Chesapeake Bay.
SCIENTIFIC  APPROACH:
     The first year is devoted  to  technique development (chemical procedures,
apparatus, software development).  Samples of sediment and raollusks are
collected once the first year and  semiannually thereafter.  Water samples are
collected twice the first year  and seasonally thereafter.  Sampling stations
are distributed throughout the  Bay.

     An online computer system  performs the bulk of the data management
tasks.  The gas chromatrographic/mass spectra data will contain information
on both identified components (i.e., those on the EPA consent decree priority
pollutants list) and unidentified  components.  The program takes note of both
classes of compounds, allowing  assessment of accumulations of recognized
toxics and maintaining a capability  to perceive alarming rates of increase in
other compounds that may force  identificatioa and further action.
PRODUCTS:
     Study results will include  a  baseline depiction of the abundance and
distribution of toxic organics  in  the water column, sediments, and mollusks
of the Bay system.  Additionally,  some previously unknown toxic organics may
be identified.  Finally, the  availability of a functioning surveillance
system for these toxic compounds will assist in making resource management
decisions.

   End   -  6/30/80
OBJECTIVES;
     Interstitial water is a vehicle by which trace metals, nutrients, and
soluble sediment constituents may be transported  across  the sediment/water
interface.  The four major project objectives are:   (1)  characterization
of the composition as well as variations in the chemistry of interstitial
water as a function of sediment type and position along  the salinity gradient,
(2) identification of sediment particle mineralogy,  (3)  interpreting the
reactions that occur between the solid phases and the  interstitial waters
that control concentrations of dissolved species  in  the  system, and
(4) determining the mechanisms as well as assessing  the  extent of transfer
across the sediment/water interface.
SCIENTIFIC APPROACH:
     Approximately 100 sediment cores  are  being  collected along a series of
east-west transects of the Bay.  Each  core yields  10 samples spaced evenly
over the topmost meter of sediment.  Interstitial  water is squeezed from each
of the samples.  Residual (squeezed) mud is analyzed for carbon content,
sulfur content, and mineralogy^  Each  interstitial water sample undergoes
electrode analyses (pH,  Eh,  pS~).  The Maryland  Geological Survey laboratory
analyzes each sample for trace metals, silica, and sulfate.  Professor S.Y.
Tyree Jr., of the College of William and Mary  (project number R805966, page 27),
performs analyses for alkalinity,  major cations, and nutrients.


PRODUCTS:
     This study will provide:   (1)  a  baseline assessment of trace metals and
nutrients in the interstitial  waters  of  Bay  sediment, (2) an evaluation of
the significance of bottom sediment as a source of nutrients and metals to
the estuary, (3) data necessary to  correlate sediment chemistry with metals
content of benthic fauna,  and  (4) data necessary to the modeling of trace
metal behavior in the estuarine environment.

     This project  provides analytical support  to  the Interstitial Water
Chemistry Project  (grant number R805963,  page  26) by performing chemical
analyses on the  pore water samples collected by the Maryland Geological
Survey.
SCIENTIFIC  APPROACH:
     Interstitial water samples will be assayed for ion concentrations of
chloride,  nitrate, nitrite, phosphate,  sulfate, sulfite, sodium, potassium,
ammonium,  calcium, magnesium, fluoride  and  hydrogen carbonate (alkalinity).
Hydrogen carbonate is determined by an  acid-base titration.  All other ions
are determined by ion chromatography.


PRODUCTS:
     Concentrations of each of the 13 critical  ions will be assembled into
10-member vertical profiles for the 100 sediment cores of the Interstitial
Water Chemistry  Project.

OBJECTIVES:
     This project evaluates the role  of  suspended sediment on the budget of
toxic substances in the Chesapeake  Bay.   There are four major study objectives:
(1) to make a seasonal characterization  (chemical, physical) of suspended
sediment in the water column in the main portion of  the Bay and in selected
major tributaries, (2) to determine exchanges of particle-associated toxics
between selected tributaries and the  main body of the Bay for average condi-
tions as well as for more extreme levels of  river discharge, (3) to evaluate
various models of transport for particle-associated  toxics, and (4) to
establish rates and patterns of movements and deposition of particle-associated
toxics.


SCIENTIFIC APPROACH:
     Monthly field surveys provide  data  on  suspended sediment concentrations
along the main axis of the Bay and  at  the mouths of major tributaries.
Quarterly cruises survey exchanges  of  sediment between tributaries and main
Bay as well as develop the relationships between suspended sediment and fluid
mud (coordinated with the Virginia  Institute of Marine Sciences' fluid mud
project number R806002,  page 29).   Basic measurements include:  suspended
sediment concentration (optical,  gravimetric), water temperature and salinity,
dissolved oxygen, particle carbon and  nitrogen, elemental composition of
particulate matter, and  chlorophyll-A  concentrations.


PRODUCTS:
     The project will result in an  evaluation of suspended sediment as a
transporting agent for toxics.   It  will  also identify sources and sinks of
toxics in various sediment types to aid  quantification of the sediment
budget.

OBJECTIVES:
     This study,  which is  a  companion  study of grant number R805959
(page 28),  investigates the  role  of  suspended sediment and fluid mud in the
fate of toxic metals  in the  Chesapeake Bay system.  Of primary interest are:
(1) spatial and temporal patterns of toxic metals in suspended sediments,
(2) preferential  states of suspended sediment (i.e., clay, organic matter,
etc.)  for  toxic  metals, and (3)  rates and routes of contaminant transport
from source to sink.
SCIENTIFIC APPROACH:
     A series of field  observations will determine the Bay-wide distribution
of metal contaminants over  a  seasonal cycle of changing sediment influx and
saline mixing.  Concentrations  of  selected metals are measured in the organic
and inorganic fractions of  suspended material through the water column and in
near-bed fluid mud.  Pertinent  environmental measurements of salinity, pH,
turbidity, and dissolved oxygen are also taken.  Mobility of suspensions and
contaminants at the  mud/water interface are monitored over two tidal cycles.


PRODUCTS:
     The study will  produce  an evaluation of the role of suspended sediments
and fluid mud in transporting toxics allied to sources and sinks and will
allow quantification of  this portion of the sediment budget.  The study will
also establish a baseline  for documenting future accumulations and depletions
of toxic metals.

OBJECTIVES:
     This study is concerned with the  Maryland portion of the Bay and is
coordinated with a similar study being conducted by the Virginia Institute of
Marine Science (grant number R805982,  page  31).  This study investigates the
relationship of benthic fauna to bottom sediments and seeks to infer the role
of benthic fauna in augmenting the exchange of dissolved material across the
sediment—water interface.


SCIENTIFIC  APPROACH:
     The Maryland portion of the Bay will be surveyed for principal physical
and biogenic structures, sediments,  benthic fauna, and characteristics of
the overlying water column.   Boxcore samples of bottom sediments will undergo
a wide range of analyses (from standard  chemical and physical tests to
X-radiography).  These analyses will:   (1) define the diversity and abundance
of the organisms, (2) relate specific animals  to certain biogenic structures
(burrows, tubes, etc.), and  (3) provide  physical and chemical information on
the sediment.


PRODUCTS:
     This study will provide a three-dimensional picture of the benthic
environment which, when correlated  with  the results of the interstitial water
projects, will provide a better picture  of the role of benthic organisms in
the exchange of toxic-laden material  across the sediment-water interface.

OBJECTIVES:
     This project seeks  to  identify the causes of oyster mortality in the
Chester River.
SCIENTIFIC APPROACH:
     The study is  conducted  in three concurrent parts:  (1) Biotoxicity
assays are conducted  at  each potential point discharge source for toxics.   A
3-1/2-month field  program  arrays a test population of oysters in the Chester
River; the test population is periodically compared to a control population.
A more detailed study employs direct exposure of crayfish and finfish to
effluents from suspected toxic discharge sources over a 96-hour period.
Patterns of morbidity and  mortality are then used to locate effluents poten-
tially responsible for oyster mortality in the estuary.  (2) Chester River
water, sediment, and  shellfish are assayed, combining gas liquid chromatography
with mass spectrometric  detection.  (3) The role of tin (organic as well as
inorganic) as a contributor  to oyster mortality is investigated by analyzing
water, sediment, and  oyster  tissues.  Each sample is examined for tin by
atomic absorption  spectrometry, for total viable aerobic bacteria, for
tin-resistant aerobic bacteria, and for ability to form organic tin compounds.
Bacterial cultures are analyzed for total organo tin compounds using atomic
absorption techniques.


PRODUCTS:
     This study will  attempt to locate and identify the agents causing the
anomalous oyster mortality and to develop control strategies to correct the
situation if appropriate.

 OBJECTIVES:
     The objective  of  this project is to identify industrial discharges of
toxic chemical  effluents in the Chesapeake Bay Basin.   A point source assess-
ment will be performed  in order to determine the amount of wastewater effluent
discharged, and the identity and concentration of possible toxic materials in
respective effluent streams.

     Both major and minor dischargers will be identified with respect to
industrial and  chemical factors.
 SCIENTIFIC  APPROACH:
     Industrial  discharges into the Chesapeake Bay Basin in  the states of
Virginia and Maryland will be studied.  Each discharger  will be identified by
NPDES permit number, location, basin, SIC code, discharge rate and mode of
discharge either direct or via a POTW.

     A chemical  inventory will be made of major dischargers  located within
the fall line of the Chesapeake Bay.


 PRODUCTS:
     A priority list of discharges will be developed.   An  inventory of
constituents of each major effluent will be compiled  in hardcopy and computer
magnetic tapes.

            SUBMERGED AQUATIC VEGETATION  PROGRAM AREA







     Submerged Aquatic Vegetation (SAV) occupies an important position in




the ecology of the Chesapeake Bay system.   SAV provides food, shelter,




habitat and breeding areas for finfish, shellfish,  waterfowl and species of




the lower trophic levels.  SAV beds act as sediment traps and wave breakers




that serve to improve bottom stability, reduce turbidity and retard shoreline




erosion.  In recent years there has been a sharp decline in the abundance of




SAV in the Bay system; this has caused alarm because it seems to correlate




wLth the overall ecological health of the Bay and may be an indicator of




significant environmental damage to the Bay system.




     A management plan for SAV must await a clear definition of the cause-and-




effect relationships that bear upon the problem.  To this end, the Chesapeake




Bay Program is addressing the Impact of water quality factors upon SAV and




those living resources known or suspected to be dependent upon SAV.  Study




products will identify, and where possible quantify, important ecosystem




functions that SAV performs in the Bay system.   These results will provide




the knowledge base from which water quality management alternatives will be




developed for the enhancement of SAV and associated living resources.

OBJECTIVES:
     This study,  a  companion project of grant number R805951  (page  36),  seeks
to (1) establish  an inventory of SAV distribution and species concentration
in Maryland waters, and  (2) assess the usefulness of archival aerial  photog-
raphy for estimating trends in distribution and abundance in  the  Bay.


SCIENTIFIC APPROACH;
     Aerial photography  and photointerpretation are utilized  to establish a
data baseline.   Photographs of the submerged aquatic vegetation are taken to
match the United  States  Geological Survey's quad sheet scale  of  1:24,000
and quality control is assured by consideration of the following  factors:
(1) SAV growing season,  (2) turbidity, (3) atmospheric haze,  (4)  wind condi-
tions, (5) sun  angle, and  (6) tide stage.  Field samples are  collected to
provide ground  truth verification of the photointerpretation  process.


PRODUCTS:
     Study products  include:   (1) a current inventory of SAV in Maryland
waters in the form of maps  showing distribution of SAV with species  annotation,
and (2) an assessment of  trends in SAV populations in selected areas where
usable historic  photography is available.

OBJECTIVES:
     There are three project  objectives:  (1) to map the present distribution
of SAV beds in the saline  portions of the Bay in Virginia, (2) to determine
changes in SAV distribution in  parts of the Lower Bay over a 40-year period,
and (3) to map SAV distribution in selected freshwater portions of the
subestuaries.  A companion study (grant number R8055977, page 35) is being
conducted by The American  University.


SCIENTIFIC APPROACH:
     Mapping of present distributions  is performed from aerial photography
of all SAV beds in the  saline  Lower Bay at a scale of 1:24,000.  A single
demonstration study of  freshwater  species of SAV in selected turbid freshwater
portions of the subestuaries is  included.  Species differentiations and
environmental conditions are verified  through surface examinations of represen-
tative SAV beds utilizing skindiving observations on selected transects.
Historical aerial  photography  for  a maximum of six saline areas and possible
freshwater areas,  obtained for years from 1937 to 1977, is compared with the
new photography to assess trends.


PRODUCTS;
      Products  include a report and a series  of maps of  the Lower Chesapeake
 Bay  showing:   (1) present distribution and  abundance of SAV,  (2) acres of SAV
 in the Lower Chesapeake Bay, and (3)  trends  of historical SAV changes in
 selected  areas.

 OBJECTIVES:
     This project  continues  the  research of grant number R805951 (page 36)
and will:  (1)  identify  those  areas in the Lower Chesapeake Bay that contain
stands of SAV with emphasis  on the saline regions, (2) obtain high-quality
aerial imagery  of  those  areas  that contain significant SAV, (3) delineate SAV
species type and distribution  in areas which have dense SAV, and (4) determine
if significant  alterations have  occurred in comparison to the similar study
conducted in 1978.  This work  is similar to work performed by the Chesapeake
Bay Foundation  (grant  number X-QO-3202-01, page 38) for the Maryland portion
of the Bay.


SCIENTIFIC APPROACH:
     The survey will be  conducted  in  two phases.  The initial phase will
survey the Lower Bay to  identify areas containing SAV.  Areas with significant
coverage (greater than 10 percent) will be noted for inclusion in the second
stage.  The second stage will  photograph the SAV in the significant zones at
an image scale of 1:24,000.  Corroborative surface missions will be conducted
in areas shown to have SAV coverage in excess of 40 percent.  Species present,
abundance, sediment type,  and  salinity will be recorded.  Representative
specimens will be submitted  to the National Herbarium for confirmation of
species.  Data will be mapped  on USGS topographic quadrangles, and the area
of SAV beds computed.   The 1979 data will be compared to data collected in
1978 to identify changes in  SAV distribution and will aid in the design of
the 1980 distribution  and abundance project.


PRODUCTS;
     Study products include  maps of SAV for 1979 with supporting documentation
and changes in SAV that  have occurred between 1978 and 1979.

      Aerial reconnaissance will be conducted to identify areas that are
 significantly vegetated. Photographs will be taken of significantly vegetated
 areas at a scale of  1:24,000.  SAV distribution and abundance maps will be
 developed for areas  showing  significant change from the 1978 inventory.
 Quality control will be  assured by consideration of the following factors:
 (1) SAV growing season,  (2)  turbidity, (3) atmospheric haze, (4) wind conditions,
 (5) sun angle,  and  (6) tide.  Field samples will be collected to provide
 ground verification  of the photointerpretation process.  The results of this
 inventory and subsequent comparison with the 1978 study will assist in
 designing the 1980  distribution and abundance project.


 PRODUCTS:
      Project results will  include:   (1) a current inventory of SAV in Maryland
waters in the form of maps  with  species annotation, of areas showing significant
distribution changes of SAV since  1978, and  (2) an estimate of trends in SAV
populations from 1978 to 1979.

OBJECTIVES:
     The project investigates the  feasibility of obtaining scientific infor-
mation for Chesapeake Bay management  from  stratigraphic analysis of sediments.
Changes in SAV populations,  eutrophication, and sedimentation rates are
defined over past time periods of  a few  hundred years or more and correlated
with natural events and human activity.


SCIENTIFIC APPROACH:
     Core samples of Bay sediments,  5 centimeters  in  diameter and up to
2 meters in length, are collected from undisturbed locations in three parts
of the Bay; Susquehanna flats and Furnace Bay  in the  Upper Bay, Eastern Bay
in the mid-Bay region, and Hungar's  Creek on the Eastern Shore at the Lower
Bay.  The cores are examined to determine the  most appropriate fossil indica-
tors of SAV and eutrophication.  Cores are split for  analyses which will
provide for extraction of SAV fossils, and for analyses for total organic
carbon, sedimentary chlorophyll, pollen and diatoms.   Cores taken from the
Bay proper are split and analyzed by pollen and Pb2io to compare the dating
methods.  Historical and meteorological dates  are  compiled for correlation
with data obtained from the core analyses.  The present study is considered
to be a feasibility study for a more detailed  program, grant number R806680
(page 40).  The effort also includes the design of a  statistically reliable
sampling procedure for further work.


PRODUCTS:
     Results of the project include vertical profile descriptions of SAV.
populations, biomass and sedimentation  rates for the period of time covered
by the extracted cores.   There  will be  a  report describing methodologies and
correlating the data on  long-term changes in SAV, eutrophication and sedimen-
tation rates to natural  events  (such  as hurricanes) and to man's impact on
the Bay during these periods.

OBJECTIVES:
     This project expands the work done  by  the  feasibility study conducted
under grant number R805962 (page 39).  The  project will study the natural
cycles of SAV and diatom populations  over several hundred years, and correlate
deviations from these cycles resulting from human impacts or natural events.
Sedimentation rates will be studied and  relationships to the natural events
and land use changes will be established.


SCIENTIFIC  APPROACH:
     Core samples of Bay sediments,  5  centimeters in diameter and up to
2 meters in length, collected from undisturbed locations in four areas of the
Bay are to be examined for fossil  indicators of SAV and eutrophication.  The
cores are split for analysis of SAV  fossils, total organic carbon, pollen and
diatoms.  Historical and meteorological  data are to be compiled for correlation
with core data.  Bay sediment samples  will  be collected from the Patuxent and
Choptank subestuaries in the Upper Bay,  and the York and Ware subestuaries in
the Lower Bay.  Additional long cores  (~12 m) will be analyzed from two
locations - one in the Upper Bay and one in the Lower Bay - to compare
changes in pre- and postsettlement core  sections.


PRODUCTS:
     There will be a report describing  methodologies and relating the data
on long-term changes in SAV, eutrophication  and  sedimentation rates to
natural events and to man's impact on the  Bay during these periods.  Data
will be computerized showing vertical profile descriptions of SAV populations,
eutrophication and sedimentation rates  for the time periods covered by the
extracted cores.

OBJECTIVES;
     This project is aimed at developing  a  technology for establishing and
propagating eelgrass (Zostera marina)  and for  determining the impact of
herbicides on the grass.   A subobjective is  the  definition of biological and
cultural factors affecting eelgrass propagation.
SCIENTIFIC  APPROACH:
     Research into the biology and  propagation of eelgrass is conducted
through field studies and sampling  of  beds on the eastern and western shore
of the Lower Bay, including biomass measurements and in-situ seed germination
experiments.  Laboratory, greenhouse and  field studies are made to determine
optimal procedures for storing and  germinating seeds, culturing seedlings and
transplanting seedlings and wild plants.  The effects of herbicides on eel-
grass are studied through field investigations of herbicide (atrazine in
particular) levels in selected Virginia Bay eelgrass areas, especially during
and after storm surges.  There will be an investigation of controlled dosing
of eelgrass beds with herbicides in specially constructed enclosures.  Rela-
tions between herbicide loadings and natural suspended sediments are also
investigated.  Sublethal effects of herbicides will be investigated at the
physiological level.
PRODUCTS;
     The project will result in  a  set  of computer-stored data, compatible
with other SAV data in the Chesapeake  Bay Program.  A report will be prepared
containing a thorough discussion of methodologies, project results and the
implications of the results for  the Bay ecosystem.

OBJECTIVES:
     Project objectives are:   (1)  to  identify  toxicity and stress levels of
herbicides, turbidity and their  synergistic effects on SAV, (2) to examine
critical pathways and mechanisms of herbicides and turbidity in relation to
SAV, (3) to identify the ecological function of SAV,  (4) to evaluate economic
and energetic costs and benefits of various watershead practices, (5) to
develop nutrient, sediment and herbicide  budgets for  the Patuxent and Choptank
subestuaries, and (6) to evaluate  management options  for controlling causative
factors in the decline of SAV.
SCIENTIFIC APPROACH:
     This project proceeds from microscale  to macroscale studies at four
levels:  (1) microcosmic laboratory  studies  of  impacts of turbidity, herbicides
and nutrients on SAV, (2) similar studies in eight specially constructed
1/8-acre ponds, (3) field sample collection  and investigation of SAV-environment
relations of representative Bay sites,  and  (4)  regional studies to investigate
land use/pollutant interactions, simulating  them mathematically in a model of
the environmetal decisionmaking process.  The hierarchical approach of this
project allows for collection and interpretation of data and testing of
hypotheses in situations of increasing  realism  and increasing complexity.


PRODUCTS:
     The project will attempt to:   (1)  determine  the  factors leading to the
decline of SAV in the Bay, (2) describe the  dependence of commercially
valuable Bay animal species upon SAV, and  (3)  result  in an ecological model
of SAV that accounts for changes in its distribution  and abundance in the
Bay.  SAV management options will be evaluated, based upon watershed utiliza-
tion practices in the Choptank and Patuxent  subestuaries.

OBJECTIVES:
     This project will qualitatively  and  quantitatively investigate the
functional ecological relationships in  submerged seagrass communities in the
Lower Chesapeake Bay.  The resulting  data and experimental approaches should:
(1) enhance basic understanding,  and  (2)  establish criteria for environmental
assessment.


SCIENTIFIC APPROACH:
     The project is divided into 4 subgroups.   These  subgroups are:  (1) pro-
ductivity, nutrient cycling and associated  microbial  metabolic activity
in eelgrass communitites,  (2) interaction involving resident consumers,
(3) higher level consumer  interactions,  and (4) ecosystem modeling.  The
approach is experimentally oriented to quantify and describe processes that
determine overall biotic community behavior.   The  research will use a team
approach concentrating on  a single site  for intensive study.  The resulting
collection of studies will generate data to assist in designing simulation
studies.  These, in turn,  will be used to evaluate specific interactions in
relation to overall system dynamics.


PRODUCTS:
     Anticipated products  include:   (1) quantification of the relative
resource value of SAV habitats,  (2)  knowledge of how SAV communities interact
with the entire Bay ecosystem,  (3) determination of the use of SAV habitats
by fish and wildlife of  importance to man,  (4) understanding of the life-
support processes which  underlie  the resource values, and (5) understanding
of the effects of loss of  SAV habitats on Bay resources.

     A final report will also include a detailed description in tabular and
graphic form of:  (1) conceptual  and simulation model versions, (2) data
requirements and output  characteristics as well as sensitivity analysis of
each version, and (3) identification of controlling or governing parameters
and perturbation studies.

OBJECTIVES;
     This project seeks to test the hypothesis  that beds of SAV (1) contain
significantly larger number of invertebrates  than adjacent unvegetated areas,
(2) harbor significantly greater concentrations of juveniles of commercially
valuable fishes and grass shrimp,  and (3)  serve as shelters for juvenile
fishes and grass shrimp where  predator efficiency is lower than in unvegetated
areas.


SCIENTIFIC  APPROACH:
     The approach is divided into two  categories:   (1) repetitive day and
night field sampling of vegetated and  nonvegetated  sites arid (2) laboratory
tank experiments using known numbers of  grass  shrimp and a predator in SAV
planted in bare sand (control) tanks.

     Sampling locations and nearby control  sites have been established in a
high salinity Zostera marina meadow near the mouth  of the York River in
Virginia and in a lower salinity Ruppia  marltima meadow near Parson's Island,
Maryland.  Day and night trawls have been taken in  the Maryland and Virginia
test and control sites.

     The laboratory experiment utilizes  two large (236 gallon) tanks to
establish predator efficiency.  An additional  series of identical experiments
will be carried out using artificial SAV to determine whether nonliving
sources may provide protection for grass shrimp.


PRODUCTS:
     The products will include data and graphs  of  abundance,  species richness
and size-frequency distributions at each of the sampling  sites. __. Estimates of
the degree of protection from predation provided by  different densities and
species of SAV will also be developed.

PROJECT PERIOD:
   Begin -  7/10/78
   End   -  7/09/79
OBJECTIVES:
     This project assesses the potential  impact of industrial effluents and
the combination of industrial effluents and herbicides on SAV.  Since little
is known about the toxicity of industrial wastes to marine organisms, the
study is to determine for selected  effluents, what fraction, organic or
inorganic, contains the toxic factor.


SCIENTIFIC APPROACH;
     Waste samples collected in the Bay were shipped by air and received at
the Gulf Breeze Laboratory the same day.  Tests were begun immediately for
chemical and biological assays.  Complex  waste samples were passed through an
XAD resin column to remove dissolved organic matter.  The purged, inorganic
fraction was then subfractioned into heavy and nonheavy metal portions using
Dowex strongly basic anion and cation  exchange resins.  Bioassays were
subfractionated into compounds extractable with acetone under acidic, basic
and neutral conditions.

     Test species were:  Zostera marina,  Thalassia testudinum, and Skeletonema
costatum.  SAV's were exposed to the toxicants in a 4-liter reaction kettle
fitted with a false bottom.  Seagrass  planted in sand in the kettles were
then observed after exposure to waste  concentrations of 25, 50, 75 and
100 percent.


PRODUCTS;
     The project produces empirical data  which will be useful in assessing
the impact of effluents on SAV.

OBJECTIVES;
     This project has two primary objectives:   (1) to determine if small-craft-
induced water turbulence leads to measurable  increases in suspended sediment
and to determine the preferred measurement  techniques, and (2) to determine
the effects of recreational boating  on  suspended sediments.
SCIENTIFIC APPROACH:
     Sediment resuspension due to small  craft induced water motion was
measured by:  (1) gravitation analysis of  suspended sediment, (2) light
extinction as measured by photometer  and (3) light scattering as measured by
transmissiomter.  Effects due to  vessel  passage were compared to values
obtained prior to vessel passes at several locations, primarily on the Rhode
River, Upper Chesapeake Bay,  and  chosen  to allow changing one variable at a
time.  Variables include water depth, sediment type, and boar type.

     Laboratory measurements  were made to  determine average velocity and
turbulence intensity due to propeller effects alone, and results will allow
an estimate of the Reynold's  stress.  This stress, when combined with data on
critical stresses for sediment resuspension, may allow prediction of the
stress distribution as a function of  depth and propeller immersion.  Measure-
ments were made using open channel flume,  a laser-Doppler anemometer, and
Fourier analyzer.

     Recreational boating effects on  suspended sediments were determined by
comparison of controlled and  uncontrolled  shallow estuarine environments.
Water transparency was measured by:   (1) gravimetric determination of suspended
solids, (2) determination of  beam transmittance, and (3) use of the Sechi
Disc.
PRODUCTS:
     The products include data correlating the effects of small craft passage,
recreational boating (waterskiing), weather, and tidal current on suspended
sediment, as well as the subsequent effect of suspended sediment on SAV.

SCIENTIFIC APPROACH:
     Historic data on migratory waterfowl habitat and feeding patterns will
be compiled.  Current distribution and feeding patterns will be evaluated
through aerial surveys and  surface verification.  The approach for the second
objective will involve a variety of graphical and statistical analyses of
data collected by CBP/SAV researchers, detailed discussions of research
results, and comparisons of these results with current and past research done
outside the CBP.

EUTROPHICATION PROJECTS

-------

-------
                      EUTROPHICATION PROGRAM AREA







     The process of nutrient enrichment,  frequently called eutrophication,




was first used to describe an advanced state in a natural process of aging




and succession in freshwater lakes.  Eutrophic means "well nourished" or




enriched in dissolved nutrients and generally implies high productivity as




well.  Excessive enrichment occurs when the resulting aquatic conditions




preclude some potential use, thereby having undesirable consequences.  Such




an excess can arise from either natural or cultural causes.  Enrichment in




estuaries can have both subtle and gross  effects which are distinctly different




from those which occur in freshwater systems.




     The undesirable effects of eutrophication in an estuarine environment




are much better understood than the possible desirable effects.   It is amply




documented that reduced levels of dissolved oxygen have occurred in the Upper




Bay and its headwaters.  It is also well  known that undesirable algal species




have started to displace desirable species which serve as food for higher




organisms in some of the Bay's principal  tributaries.  However,  little is




known about the contribution of nutrient  enrichment to possibly higher yields




of finfish and shellfish and other products derived by man from the Chesapeake




Bay system.




     Even if it were possible to assume that the undesirable effects of




eutrophication by far outweigh its contribution, the program is still faced




with the problem of devising cost-effective control strategies for nutrients.
                                     48

-------
This however requires a thorough understanding of nutrient sources, particu-




larly quantification of the relative contribution of point and nonpoint




sources.




     This program is designed to take a new look at the eutrophication




question and to assure that eutrophication does not interfere with a maximi-




zation of beneficial uses of the Chesapeake Bay system.  Presumably, if




eutrophication is controlled, society will receive some possible long-range




benefit.  A higher level of nutrient control should result in more benefits;




however, higher control levels have greater costs.  The costs to implement




the particular control strategy should be justified by the benefits derived




from reducing the eutrophication level.

OBJECTIVES;
     The objectives of this  program  are:   (1) to provide a summary of the
fundamentals of nutrient  enrichment  as  related to the Chesapeake Bay specif-
ically and estuaries in general,  (2)  to describe nutrient enrichment of the
Bay from a historical as  well  as  contemporary perspective, (3) to apply and
improve existing indicators  and indices for nutrient enrichment for the Bay,
(4) to explore and express  the relationships between the nutrient enrichment
and the consequences in the  ecosystem as well as to Bay users, and (5) to
define the related needs  for future  research and monitoring of conditions in
the Chesapeake Bay.
SCIENTIFIC APPROACH:
     The project workplan calls  for  an  extensive literature survey, a thorough

OBJECTIVES;
      The  project includes detailed investigations of  sediment, nutrient, and
 pesticide loadings in the surface waters of the Pequea  Creek Basin.  The
 project is one of fout evaluating five watersheds in  Maryland, Virginia and
 Pennsylvania.  Emphasis will be on obtaining runoff rates  from the various
 land  use  categories in this Basin, a high yielding agricultural area of the
 lower Susquehanna River.


SCIENTIFIC  APPROACH;
      The  established pattern of data collection in the  study area  Ls to be
 continued.  The automated sampling station at the downstream limit of the
 study area from the previous year will be retained.   Five  new automated
 stations  will be established in small areas of single land uses representative
 of  the lower Susquehanna River Basin.  Samples will be  collected during all
 storm runoff periods at all six stations.  Four storms  during the  year will
 be  manually sampled in conjunction with automatic sampling to define changes
 in  concentrations of constituents with the rise and fall of the stream during
 storms.   Periodic baseflow, precipitation and soil samples will also be
 collected.
PRODUCTS:
     This project will provide further field verification  information about
 links between agricultural practice and resulting  sediment-nurient-pesticide
 loading of surface water courses.  This information  will aid  in assessing
 the contribution of nonpoint source discharges  of  these materials  from the
 lower Susquehanna River Basin to the Bay system.

OBJECTIVES;
     Utilizing the  field  data collected in the watershed studies in Maryland,
Pennsylvania and Virginia,  this study seeks to (1) evaluate the relative
effectiveness and basic accuracy of existing computer models as tools for
the management of eutrophication in subestuaries of Chesapeake Bay and
(2) provide information on  the most cost-effective combination of models
tested.
 SCIENTIFIC APPROACH:
     The approach uses  computer model simulations to help identify factors
affecting eutrophication  in  the Bay and to get a better understanding of
how various point and nonpoint sources and water quality processes affect
eutrophication of the subestuaries and nutrient loadings to the Bay.  Models
describing urban and rural nonpoint-source nutrient loading, stream transport,
and estuarine processes will be linked into compatible sets.  These sets will
be calibrated and tested  to  determine their accuracy in projecting real-life
scenarios.  Steps will  be taken as follows:  (1) develop criteria for selecting
analytical tools necessary for effective management of eutrophication in the
Bay, (2) develop an inventory of models to be tested and recommend operational
procedures for their use, (3) calibrate the sets of models selected, and
(4) test each set of models  and transfer the technology to EPA and the State.
 PRODUCTS:
     The products of this  study will include (1) a summary report giving
present estimates of net nutrient  loadings to the Bay and (2) an assessment
of the usefulness of computer modeling in predicting and evaluating nutrient
loadings including estimates of costs of running the various models.

OBJECTIVES:
     This project evaluates the  water  quality (chemical and biological)
of the Chesapeake Bay and selected  subestuaries.  Water quality information
will be correlated with LANDSAT  imagery.  A helicopter-borne water quality
sampling system will be evaluated.


SCIENTIFIC  APPROACH:
     Program modeling requirements will  guide the selection of locations for
water samples. The helicopter-borne water quality monitoring system will
record depth, pH, conductivity/salinity, temperature and dissolved oxygen.
Those measurements will be compared with LANDSAT observations made during
selected overpasses.   The resulting data will be compared for accuracy and
will be used in evaluating physical,  biological and oxygen-related parameters,
as well as concentration of toxicants and levels of nutrients.


PRODUCTS:
     The products of this study  will  include:  (1) a statement of the relative
efficiencies and reliability of  helicopter versus LANDSAT water quality
monitoring, and (2) data which will be used to refine Bay models developed  to
assist policymakers in answering questions related to the pollution control
in the Bay system.

                ENVIRONMENTAL MANAGEMENT PROGRAM  AREA






     In authorizing the Environmental  Protection Agency  to undertake the




Chesapeake Bay Program study,  Congress specifically directed the Agency to




examine Bay management.   Three  priority research tasks  have been identified as




vital to a better understanding  of  the factors affecting and influencing the




Bay decision process.   They are:  (1)  identify, review and catalog regional




water resources management agencies,  (2) review and catalog Bay management




agencies, and (3) analyze the  effectiveness  of present Bay management mechanisms.




     This series of research tasks  will assure that all  the related components




of the Bay Program work together smoothly  and efficiently to achieve the




objective of a better  Bay.  The  Environmental Management Program includes




tasks to support and refine the  existing management strategies and to analyze




alternative scenarios  for Bay  management.

OBJECTIVES;
     This study pursues  three objectives:  (!) to describe the  present
system of environmental  management at all levels for the Chesapeake;  Bay,
(2) to propose  alternative management systems where warranted,  and (3)  to
estimate the costs  and benefits of such changes.
SCIENTIFIC APPROACH:
     Resources  for  the Future and the Conservation Foundation will  assist  the
Environmental Law Institute in performing three major tasks:   (1) identify
Federal,  interstate,  state, and local government agencies  involved  with Bay
management,  (2) describe  the roles of each agency in managing the Bay, and
(3) develop  procedural and institutional alternatives that will  improve
environmental management  of the Bay.  All major tasks will be undertaken
within the context  of researching management relative to the  technical areas
of Toxics, Eutrophication and Submerged Aquatic Vegetation.
PRODUCTS:
     The results  of  this  study will serve to coordinate the separate  study
areas (Toxics,  Eutrophication, Submerged Aquatic Vegetation,  Public Partici-
pation) into an integrated management plan for maintaining the  quality  of the
Chesapeake Bay  system.

                           STATE PARTICIPATION




     Representative agencies from both Maryland and Virginia State  governments




support the Chesapeake Bay Program by providing key coordination links  on both




inter- and intrastate levels.  At this time the states are concentrating  on




assessing Bay user needs, identifying and reviewing existing programs,  and




designing and implementing new programs when necessary.




     The close coordination and involvement by the states  allows both the State




government and the Chesapeake Bay Program office to most efficiently allocate




their resources in identifying and resolving the Bay water quality  problems.

PUBLIC PARTICIPATION PROJECTS

-------
                         PUBLIC PARTICIPATION






     Citizens, by being active and  concerned about community issues,  play




an important role in influencing both the direction and magnitude of  govern-




ment actions.  The process of public participation results in two immediate




benefits:  (1) government leaders become aware of and more responsive to




public concerns, and (2) the citizens can better understand the efforts




undertaken by government in response to problems.




     The Chesapeake Bay is fortunate to have a public that is actively




concerned about the environmental health of the Bay.  The programs described




under Public Participation are designed to facilitate a two-way communication




flow between the citizens in the Bay area and the Chesapeake Bay Program




management.

OBJECTIVES:
     The objectives of the Public Participation Program are: (1) to raise the
level of public awareness concerning the  environment of the Chesapeake Bay,
(2) to increase the public's understanding  of  the Chesapeake Bay Program and
its goals and objectives, (3) to provide  Chesapeake Bay Program management
with citizen input concerning the Bay,  (4)  and to involve the public in the
Program's decisionmaking process.


SCIENTIFIC APPROACH:
     During the first year of the Public  Participation Program, a variety of
communication approaches were used to facilitate a better understanding by
the public of the activities and goals of the Chesapeake Bay Program and to
give the Bay Program management a clear understanding of the citizen's
priorities, needs and concerns regarding  the Bay.  Specific actions taken
include:  (1) a 16-member Citizens Steering Committee was established,
(2) seven forums were sponsored, (3)  presentations on the Bay Program were
delivered at 37 citizen meetings, (4) a 52-minute film was produced and
telecast by Bay-area stations, (5) a  slide presentation was developed and has
been used at each of the meetings, and (6) a bimonthly newsletter was mailed
to 5,000 individuals.  Numerous fact  sheets, brochures, flyers, newsletters,
press releases and posters have also  been developed and widely circulated.


PRODUCTS:
     While the level of citizen awareness  is  difficult  to measure without
sophisticated and extensive opinion polls,  public exposure to the information
stream and management exposure to the  CSC  and Bay citizens both suggest that
the level of mutual understanding has  been raised.

OBJECTIVES:
     This project continues the work of the  first-year program executed under
project number T900748 with the objectives of:   (1) raising the level of
public awareness and understanding of the Chesapeake Bay Program's goals and
objectives, and (2) providing program management with citizen input concerning
the Bay and the Bay program.


SCIENTIFIC APPROACH:
     The Citizen's Program for the Chesapeake  Bay, Inc.  (CBCP) has established
an office in Hampton, Virginia and one in Baltimore, Maryland to enable it to
effectively reach Bay citizens.  A network of  staff located regionally around
the Bay enables CPCB to have grass roots  contact with organizations and
individuals.  CPCB is working closely with other public  participation efforts
(i.e., 208, CZM, Corps of Engineers,  Sea  Grant) to achieve a necessary level
of coordination and to eliminate duplication.


PRODUCTS:
     The CPCB effort has maintained  a Citizens Steering Committee whose
function is to advise EPA on the  conduct  of  the Chesapeake Bay Program.
Other products include the continuation and  enhancement of the 1st year
activities and Steering Committee reports, posters, a miniproject program, a
newspaper supplement on the Bay Program,  a computerized mailing list of
organizations and individuals interested  in  the Bay, a multiprogram exhibit,
a set of radio and television public service announcements and workshops
designed to acquaint the public with the  Bay Program and give them an oppor-
tunity to become involved in it.

                        DATA  MANAGEMENT  PROJECT






     In the process of evaluating the ecological  health  of  an  estuarine




system such as the Chesapeake  Bay,  large  and  complex  sets of data are generated




and must be maintained.  Scientists and researchers rely heavily on both data




interpretation and computer modeling techniques to  better understand the




interrelationships of the factors affecting the Bay.




     Data management must provide for software design, implementation, and




system operations necessary to support the  complex  data  sets developed through




Chesapeake Bay Program projects.
