1.0 INTRODUCTION
The Fernandina Beach, Florida Ocean Dredged Material Disposal Site (ODMDS) was
investigated by the U.S. Environmental Protection Agency (EPA) during 2005 as part of a
monitoring study of dredged material disposal at the site. One aspect of this evaluation was
benthic community characterization, which was accomplished via sample collection by EPA
personnel and laboratory and data analysis by Barry A. Vittor & Associates, Inc. (BVA).
The Fernandina Beach ODMDS is located approximately 7 nautical miles east of
Fernandina Beach, FL and 8.5 nautical miles northeast of the St. Johns River entrance channel.
Six benthic monitoring stations were located within the disposal area and six stations were
located just outside this area (Table 1, Figure 1).
2.0 METHODS
2.1 Sample Collection And Handling
A modified-Young grab (area = 0.04 m2) was used to collect bottom samples at each of
twelve stations (Figure 1). Six stations were located within the ODMDS and six were positioned
outside the ODMDS. Macroinfaunal samples were sieved through a 0.5-mm mesh screen and
preserved with 10% formalin on ship. Macroinfaunal samples were transported to the BVA
laboratory in Mobile, Alabama. Samples were also collected at each station for sediment texture
analysis.
2.2 Macroinfaunal Sample Analysis
In BVA's laboratory, benthic samples were inventoried, rinsed gently through a 0.5-mm
mesh sieve to remove preservatives and sediment, stained with Rose Bengal, and stored in 70%
isopropanol solution until processing. Sample material (sediment, detritus, organisms) was
placed in white enamel trays for sorting under Wild M-5A dissecting microscopes. All
5
-------
macroinvertebrates were carefully removed with forceps and placed in labeled glass vials
containing 70% isopropanol. Each vial represented a major taxonomic group (e.g. Oligochaeta,
Mollusca, Arthropoda). Oligochaetes were individually mounted and cleared on microscope
slides prior to identification. All sorted macroinvertebrates were identified to the lowest practical
identification level (LPIL), which in most cases was to species level unless the specimen was a
juvenile, damaged, or otherwise unidentifiable. The number of individuals of each taxon,
excluding fragments, was recorded. A voucher collection was prepared, composed of
representative individuals of each species not previously encountered in samples from the region.
Each sample was analyzed for wet-weight biomass (g/m2) for the major taxonomic
groups identified. After identification, each taxonomic group was kept in separate vials and
preserved in 70% isopropyl alcohol. A biomass technician removed the organisms from a vial,
placed them on a filter paper pad, gently blotted them with a paper towel to remove moisture,
placed them in a tared weighing pan, and weighed the pan to the nearest 0.1 mg using a Mettler
Model AG-104 balance.
3.0 DATA ANALYSIS METHODS
3.1 Assemblage Analyses
All data generated as a result of laboratory analysis of macroinfauna samples were first
coded on data sheets. Enumeration data were entered for each species according to station and
replicate. These data were reduced to a data summary report for each station, which included a
taxonomic species list and benthic community parameters information. Documentation of BVA's
standard QA/QC procedures and results for this project are available upon request.
Several numerical indices were chosen for analysis and interpretation of the
macroinfaunal data. Infaunal abundance is reported as the total number of individuals per station
6
-------
and the total number of individuals per square meter (= density). Taxa richness is reported as the
number of taxa represented in a given station collection.
Taxa diversity, which is often related to the ecological stability and environmental
"quality" of the benthos, was estimated by Shannon's Index (Pielou, 1966), according to the
following formula:
s
H' = - 2 pipi)
i=l
where, S = the number of taxa in the sample,
i = the i'th taxa in the sample, and
pi = the number of individuals of the i'th taxa divided by the total number of
individuals in the sample.
Taxa diversity within a given community is dependent upon the number of taxa present
(taxa richness) and the distribution of all individuals among those taxa (equitability or evenness).
In order to quantify and compare the equitability in the fauna to the taxa diversity for a given
area, Pielou's Index J' (Pielou, 1966) was calculated as J' = H'/lnS, where InS = H'max, or the
maximum possible diversity, when all taxa are represented by the same number of individuals;
thus, J' = H' /H' max. An additional measure of richness, Margalef's D, was calculated as
(s-l)/ln(n), where s = number of taxa and n = total number of individuals (Pielou 1966).
Univariate comparisons (ANOVA) of biomass, taxa richness and density were made
assuming that each station within and outside the ODMDS were replicates.
3.2 Cluster, ANOSIM and SIMPER Analyses
Cluster analysis was performed on the benthic macroinvertebrate data by calculating the
Bray-Curtis similarity coefficient for all pairs of sampling stations, after having transformed (e.g.
7
-------
square root, lne) the original taxa abundances (Clarke and Gorley 2003). Clusters were formed
using the group-average linkage method between similarities. A non-parametric multi-
dimensional scaling (MDS) was then performed on the similarity matrix generated by the cluster
analysis. MDS represents sample stations in 2-dimensional space such that the relative distances
apart of all points were in the same rank order as the relative dissimilarities of the samples as
calculated by the Bray-Curtis coefficients. Points close together in an MDS plot represents
sample stations that were very similar in taxa composition and points that were far apart
represent very different assemblages (Clarke and Gorley 2003).
The ANOSIM (Analysis of Similarities) test was calculated to assess assemblage
differences between samples within and outside the ODMDS using the Bray-Curtis similarity
matrix. Subsequently, the SIMPER test was used to identify which taxa accounted for any
observed differences between assemblage groups. The ANOSIM and SIMPER tests were
calculated using PRIMER (Clarke and Gorley 2003).
4.0 HABITAT CHARACTERISTICS
Sediment data for the 12 stations are given in Table 2 and Figure 2. Bottom sediments at
stations outside the ODMDS averaged > 98% sand. Sediments inside the ODMDS at Stations
F04, F08 and F09 averaged > 97% sand, while Stations F05, F06 and F10 had significant gravel
fractions (20%, 18% and 39%, respectively). In a 1989 benthic survey of the ODMDS, the outer
five stations surveyed averaged >93% sand, while three stations inside the ODMDS had >75%
sand and two other stations inside the ODMDS had significant gravel fractions (>21%) (Table
2).

5.0 BENTHIC COMMUNITY CHARACTERIZATION
5.1 Faunal Composition, Abundance, And Community Structure
A total of 2251 organisms, representing 255 taxa, were identified from the 12 stations
(Table 3). Polychaetes were the most numerous organisms present representing 58.9% of the
total assemblage, followed in abundance by bivalves (13.3%), malacostracans (10.2%) and
gastropods (6.0%). Polychaetes represented 45.1% of the total number of taxa followed by
malacostracans (23.5%), bivalves (11.4%) and gastropods (9.0%) (Table 3). The percent
abundance of major taxa at each station is given in Table 4 and Figure 3. Station F01 outside the
ODMDS was dominated by annelids (polychaetes), while the remaining stations outside the
ODMDS were dominated by a mixed annelid/mollusk assemblage. Three stations within the
ODMDS (F04, F05, F10) were dominated by annelids (polychaetes). Station F06 was dominated
by a mixed annelid/mollusk assemblage and Station F09 by a mixed annelid/malacostracan
assemblage (Table 4, Figure 3).
Wet-weight biomass data for the major taxonomic groups is summarized for each station
are given in Table 5 and Figure 4. Biomass at Stations F01, F02, F03, F11 and F12 outside the
ODMDS had a wet-weight biomass <0.5 g/m2, while Station F07 had a weight-biomass of
2.1544 g/m2 due to the abundance of arthropods (Table 5). Biomass at Stations F04, F08 and F09
inside the ODMDS had wet-weight biomass < 0.1 g/m2. Biomass at Stations F05 and F06 was
dominated by mollusks, while biomass at Station F10 was dominated by both annelids and
mollusks (Figure 4). The average biomass inside the ODMDS was 0.9566 (SD = 0.9194) and
0.5564 (SD = 0.5873) outside the ODMDS. There was no significant difference, however, in
biomass between stations inside and outside the ODMDS (F = 5.32, P = 0.44, df = 1,8).
9
-------
The dominant taxon collected from the 12 Fernandina ODMDS stations was the
polychaete, Bhawania heteroseta, representing 5.2% of the total number of individuals (Table 6).
Other dominant taxa collected included the polychaete Family, Maldanidae (LPIL) and the
polychaetes, Prionospio cristata, Mediomastus (LPIL) and Polygordius (LPIL) representing
4.9%, 4.6%, 3.9% and 3.1% of the total assemblage, respectively (Table 6). The chordate,
Branchiostoma (LPIL) was the most widely distributed taxon being found at 67% of the stations
(Table 6). Those taxa representing more than 5% of the assemblage at each station are given in
Table 7. In general the stations outside the ODMDS were dominated by a mixed assemblage of
polychaetes, bivalves and gastropods, while the assemblages within the ODMDS were
dominated by various polychaete taxa (Table 7).
Taxa richness data for the 12 ODMDS stations are given in Table 8 and Figure 5. Taxa
richness ranged from 20 taxa/station at Station F03 to 50 taxa/station at Station F01 outside the
ODMDS and from 20 at Station F08 to 88 at Station F05 inside the ODMDS. Taxa richness
averaged 34.0 taxa/station outside the ODMDS and 54.0 taxa/station inside the ODMDS. There
was no significant difference in taxa richness between stations inside and outside the ODMDS (F
= 4.965, P = 0.196, df= 1, 10).
Density data for the 12 ODMDS stations are given in Table 8 and Figure 6. Densities
ranged from 625 organisms/m2 at Station F07 to 3800 organisms/m2 at Station F01 outside the
ODMDS and from 1025 organisms/m2 at Station F08 to 17875 organisms/m2 at Station F10
inside the ODMDS. Densities averaged 2025.0 organisms/m2 outside the ODMDS and 7354.2
organisms/m2 inside the ODMDS. There was no significant difference in density between
stations inside and outside the ODMDS (F = 4.965, P = 0.113, df = 1, 10).
10
-------
Taxa diversity and evenness for the ODMDS stations are given in Table 8 and Figures 7
and 8. Taxa diversity (H') showed a similar range of variation outside and within the ODMDS
and averaged 3.09 and 3.24, respectively (Table 8). Taxa evenness (J') also exhibited a similar
range of variation outside and within the ODMDS and averaged 0.90 and 0.86, respectively. The
community indices showed considerable uniformity between stations. There was no predictable
pattern in community indices between stations within and outside the disposal area (Figures 7
and 8).
5.2 Cluster, ANOSIM and SIMPER Analyses
Cluster analysis of the 12 ODMDS stations is given in Figure 9. There were two main
clusters of stations; the first cluster included all of the stations outside the ODMDS except for
Station F11 and Stations F04 and F08 from within the ODMDS; the second cluster included
Stations F05, F06 and F10 from within the ODMDS and Station F09 and F11 from outside the
ODMDS. Stations F05, F06 and F10 clustered together and the assemblages probably reflected
the fact that the sediment at these stations was distinct from that found at the other stations
(gravelly sand and sandy gravel vs sand). The results of the MDS analysis are given in Figure 10.
The groupings in the MDS reflect the major groupings found in the cluster analysis. Stations
F05, F06 and F10 again were in a tight grouping reflecting similar biological assemblages;
Station F09, Fll and F07 were outliers, while the remaining stations had similar assemblages
(Figure 10).
The results of the ANOSIM reflect the general similarity in assemblages between stations
within and outside the ODMDS: Global R = 0.109, significance of R = 18.2% - these data
indicate that the null hypothesis that the assemblages within and outside the ODMDS are similar
11
-------
should be accepted. The results of the SIMPER analysis which list those taxa contributing to the
dissimilarity between stations within and outside the ODMDS are given in Appendix I.
6.0 2005 vs. 1989 COMPARISONS
Biological data collected from the disposal site in 2005 can be compared to data collected
from the same site in 1989 (Barry A. Vittor & Associates, Inc. 1990). Sediment texture data
from 1989 and 2005 are summarized in Table 2 and Figure 11. Sediment composition at the 5
stations sampled outside the ODMDS in 1989 was variable: sand was found at Stations F6 and
F12, silty sand at Station F1 and slightly gravelly sand at Stations F2 and Fll. Sediment
composition at the 6 stations outside the ODMDS sampled in 2005 was >97% sand. Sediment at
stations within the ODMDS in 1989 was also variable with sand at one station, slightly gravelly
sand at two stations and gravelly sand at two stations. In 2005, three stations had sandy
sediments (F04, F08, F09), two had gravelly sand sediments (F05 and F06) and one had sandy
gravel sediments (F10).
One biologically significant difference between the 1989 and 2005 events was in the total
number of samples taken. In 1989, fifteen replicates were taken (using a 0.0079 m2 diver core) at
each of the ten stations for a total of 147 samples (3 samples were lost during processing)
compared to a single sample taken with a modified Young grab (0.04 m2) at each of the 12
stations in 2005 for a total of 12 samples. The discrepancy in the number of samples taken has a
potentially biologically significant effect on the number of taxa collected as well as the overall
abundance of the taxa.
In 1989, 15823 individuals representing 423 taxa were collected from 147 samples
collected at the 10 stations. Annelids (polychaetes) were the dominant taxa collected
representing 46% of the individuals and 40% of the taxa collected. Dominant polychaetes
12
-------
included the Family Serpulidae, Exogone dispar, Parapionosyllis longicirrata, Bhawania
heteroseta and Polygordius (LPIL). Arthropods represented 7% of individuals and 29% of taxa
collected. Dominant arthropods included the ostracod, Reticulocythereis sp. A and Acetes sp. A
and Glyptoplax (LPIL). Mollusks represented 42% of the individuals and 25% of the taxa.
Dominant mollusks included Crassinella lunulata and Gouldia cerina. The dominant annelid and
mollusk taxa collected in 2005 were similar to those collected in 1989 (Table 6). The arthropod
dominants between 1989 and 2005 were different, probably due to chance (147 samples were
analyzed in 1989, but only 12 in 2005) and the low abundances of this group in both years.
In 1989, stations inside the ODMDS had significantly higher taxa richness and density
than stations outside the ODMDS (Table 9, Barry A. Vittor & Associates, Inc. 1990). Taxa
richness inside the ODMDS averaged 29.5 taxa/station and 19.6 taxa/station outside the
ODMDS, while densities averaged 19152.2 organisms/m2 inside and 7746.0 organisms/m2
outside the ODMDS (Table 9). In 2005 taxa richness was higher both inside (54.0 vs. 29.5) and
outside (34.0 vs. 19.6) the ODMDS than in 1989. In 1989 densities were higher both within
(19152.2 vs. 7354.2) and outside (7746.0 vs. 2025.0) the ODMDS than in 2005. However,
comparisons of taxa richness and density between 1989 and 2005 are problematic due to
differences in sampling methodologies.
