ABSTRACT (Continue on reverse sides if necessary and identify by block number) 
This report gives biological and physical oceanographic data from base- 
line work, and studies of dredged and undredged sediments before and after 
dredging (9-meter contour) for beach nourishment at Panama City Beach, Florida 
These studies were designed to show major short-term environmental effects of 
offshore dredging and included analyses of hydrology, sediments, and benthos.

Hydrological measurements were limited to water temperature and salinity. 
Analysis of surface sediments included particle-size distribution, carbon chem- 
istry, and statistical properties of mean grain size, sorting, skewness, and 
kurtosis. Average and extreme periods of water temperature and salinity were 
recorded. Regional nearshore sediments proved to be fine sand, containing less 
than 1 percent silt-clay, that was moderately well to well sorted, symmetrical 
to coarsely skewed, and leptokurtic. Total carbon content averaged less than 
0.30 percent, and most of that occurred in the form of carbonate deposits. Over 
a postdredging study period of 1 year, sediment samples from borrow pits showed 
little variation from these general features. 


In studies of the benthos, 362 species and 58,068 individuals were recorded 
among 14 invertebrate phyla and bony fishes. Dominant groups by species and 
abundance included annelida, mollusca, and arthropoda (crustacea). Faunal com- 
parisons between dredged and undredged areas were made on the basis of species 
richness and abundance, the Shannon-Weaver index of diversity (H'), Pielou's 
index of equitability (J'), Morisita's index of faunal similarity (together with 
matrices and classification diagrams derived from that index), and two statisti- 
cal derivations, based on diversity and abundance data, that were designed to 
show sample-to-sample faunal variations and the time period required for faunal 
recovery in borrow pits. Information obtained from these procedures showed that 
recovery began soon after dredging and was complete, or nearly so, within 1 year, 


These results were similar in most respects to those from study of offshore 
dredging elsewhere in comparable geographic settings. Even so, the need for 
close association between ecological research and coastal engineering programs 
is emphasized.

BENTHIC COMMUNITY RESPONSE 
TO DREDGING BORROW PITS, 


PANAMA CITY BEACH, FLORIDA

I. INTRODUCTION 


1. Background. 


On the gulf coast of northwestern Florida, at Panama City Beach, major 
environmental alterations over the past 10 years have provided an exceptional 
opportunity to determine the degree and duration of these alterations 
associated with the practice of dredging and beach nourishment. Historically, 
these events have included the development of several engineering plans, the 
intervention of a major hurricane, an emergency dredging and beach restoration 
program, and several ecological studies related to disturbances caused by both 
the hurricane and the dredging. 


In 1970, the Senate Committee on Public Works acknowledged an urgent need 
for beach erosion control and hurricane protection at Panama City Beach. This 
critical situation was referred to the U.S. Army Engineer District, Mobile, 
for study. In 1975, the Mobile District completed a feasibility report that 
contained recommendations for beach nourishment and maintenance along 29.8 
kilometers of shoreline from the entrance to St. Andrew Bay, west to Philips 
Inlet (Wilson, 1975). During preparation of the report, the U.S. Army Coastal 
Engineering Research Center (CERC) sponsored a research program to determine 
ecological changes that could be expected from the dredging and coastal 
construction work. This investigation, which was conducted by the National 
Marine Fisheries Service (NMFS) between November 1974 and October 1975, 
involved the study of hydrology, sediments, and benthic fauna at two offshore 
stations, and at five stations on each of nine nearshore transects. Emphasis 
was placed on diversity; abundance, and distribution of bottom-dwelling 
invertebrates which are directly affected by dredging and redistribution of 
sediments (Saloman, 1976). 


Before this investigation was completed, Hurricane Eloise struck Panama 
City Beach (25 September 1975). Winds up to 185 kilometers per hour and seas 
estimated at 9 meters caused severe erosion and extensive property damage 
(Saloman, 1976; Salsman and Ciesluk, 1978). In winter months that followed, 
high wind and waves associated with periodic cold fronts caused further shore- 
line erosion. 


In anticipation of the storm, and realizing the opportunity to measure 
large-scale environmental changes alongshore, NMFS conducted an intertidal 
benthic survey that consisted of faunal sampling before the storm and during 
a l-month period after the storm. The pattern of faunal disruption and re- 
covery recorded in this unique study provided considerable insight into the 
sequence of population changes to be expected in the proposed beach nourish- 
ment program (Saloman and Naughton, 1977). 


In the next year (July-August 1976), the Corps of Engineers funded an 
emergency dredging operation to restore the most ravaged beach areas and 
established berms to provide temporary protection against storms normally 
occurring during fall and winter seasons. Numerous borrow areas, 305 to 610 
meters offshore (6- to 9-meter depth) were dredged and about 306,000 cubic 
meters of sand was pumped ashore at 23 distribution sites (U.S. Army 
Engineer District, Mobile, 1976). 


At the same time, NMFS again conducted studies of the nearshore environ- 
ment over a 3-month period prior to dredging, during dredging, and for about 
6 months after dredging was completed. Benthic sampling sites were selected 
in nourishment areas and in unrestored areas. The location of the three 
nourishment areas coincided with the location of benthic base-line data 
collected in 1974 (Saloman and Naughton, unpublished data). 


Based on emergency nourishment experience and the analysis of the 
Hurricane Eloise data collected, the Mobile District revised original plans 
for shoreline protection and maintenance at Panama City Beach. The revised 
plan included berm enlargement on the beach front and additions to height and 
width of backbeach dunes. Consequently, the volume of sand estimated for 
original construction was increased from 4 to 8 million cubic meters; and 
borrow areas formerly selected at 9-meter depths were relocated seaward along 
the 18-meter bottom contour (Wilson, 1976). 


Onshore, the environmental impact of this latest plan can probably be 
predicted to a high degree of accuracy on the basis of findings in NMFS beach 
surveys in 1974 and 1976. Briefly stated, the results of these investigations 
showed that shallow, subtidal and intertidal faunas recover rapidly following 
major disturbances (natural or man-induced). A more recent study funded by 
CERC provides additional information on the long-term environmental effects 
of dredging in offshore borrow areas at Panama City Beach (Culter and Mahadevan, 
1982). A study of short-term environmental effects of dredging in offshore 
borrow areas at Panama City Beach is the subject of the present report. 


2. Purpose. 
This report provides a comprehensive analysis of benthic data from studies 


designed to show short-term environmental effects of offshore dredging during 
the emergency restoration project at Panama City Beach in July-August 1976. 


It is based on comparisons of hydrological, sedimentological, and biological 
data from collections at stations A and B in base-line studies that began in 
1974 (Saloman, 1976), and from control and experimental samples taken by NMFS 
in undredged bottom and borrow areas over a 20-month period between April 1976 
and November 1977. 


II. STUDY AREA 


Panama City Beach is located on the northwestern gulf coast of Florida 
about 145 kilometers east of Pensacola. The study area covers 35 kilometers 
and extends from West Pass at the entrance to St. Andrew Bay, to Philips Inlet 
(Fig. 1). The beach's sugarlike sand and exceptionally clear water are major 
attractions for about 2 million visitors annually. Tourism is a great economic 
asset and most of the beach has been developed to accommodate tourists and 
provide various types of recreation. 


Regional meteorological and oceanographic conditions were described by 
Salsman and Ciesluk (1978). Climate is humid and subtropical. Average summer 
and winter air temperatures are 28° and 12° Celsius, with about the same water 
temperatures at respective seasons. Winds are 20 kilometers per hour or less 
at most times, and rarely exceed 37 kilometers per hour. From spring through 
late summer, the net wind direction is southerly, but between September and 
January, the direction shifts to northerly. Waves are usually about 0.9 
meter; tides are diurnal, and tidal amplitude is normally about 0.6 meter; and 
tidal currents are generally below 4 kilometers per hour. However, during 
tropical storms and ahead of cold fronts, strong winds off the gulf produce 
waves, tides, and currents far greater than average. Even in less severe 
weather, beach sand is easily eroded because of its fine texture (0.1- to 0.2- 
millimeter median diameter). Seaward, a series of parallel sandbars protects 
the beach to some extent, but beyond, the featureless bottom slopes rather 
quickly to a 15-meter depth at 1.6 kilometers from shore. At greater depths, 
sediments are somewhat coarser and widely scattered limestone reefs appear in 
low relief. 


III. SAMPLING STATIONS AND RATIONALE 


The sampling data in this report were collected in about 9 meters of water 
at stations located offshore of Panama City Beach. As a matter of convenience, 
and for clarity, these stations have been separated into three groups since 
there were differences in their locations, sampling procedures, and objectives. 


The first group includes stations A and B (Fig. 2) of the preconstruction 
investigation of 1974-75. Station A was located seaward of the Fiesta Motel 
about midway between West Pass and Philips Inlet. Station B was seaward of the 
Roundtowner Motel, which is just east of Philips Inlet. The sampling schedule 
at these stations consisted of an initial collection in November 1974, and 
subsequent quarterly collections in February, May, and August 1975. Both were 
sampled before beach nourishment to determine seasonal environmental conditions 
(base-line data) in the zone designated for dredging (Saloman, 1976).

The second group contains station 1 (Fig. 2), located seaward of Treasure 
Island Motel (near the eastern end of the study area), which had two collect- 
ing areas--one at the borrow site and the other a short distance away on 
undredged bottom. Samples were taken from the designated borrow site before 
dredging in April, June, and July 1976. Then 2 days after dredging (10 August 
1976), concurrent sampling was started inside and outside the borrow pit. 
Sampling in both the pit (experimental samples) and adjacent to it (control 
samples) continued on a weekly schedule for 1 month. Samples were taken twice 
the next month, and then monthly thereafter until the study was concluded in 
November 1977. These samples were collected to record diversity and abundance 
of benthic fauna at a specific dredge site before dredging started, and then, 
over time, to compare population characteristics of control samples with 
experimental samples. 


The third group includes stations 1, 2, 3, 4, 5, and 6 for one-time 
sampling only inside and outside borrow pits during July 1977--about 12 months 
after dredging (Fig. 2). The six stations were located seaward of the follow- 
ing landmarks: station 1, Treasure Island Motel; station 2, Sun and Swim Motel; 
station 3, Hilton Holiday Inn; station 4, Sandpiper Motel, station 5, Peppertree 
Condominium (now Landmark Condominium); and station 6, Blue Dolphin Motel. 

These collections provided a comparison of fauna in control and experimental 
samples from a number of borrow pits for an evaluation of short-term recovery 
within a period of 1 year. Throughout this report, samples from stations A 
and B, and preconstruction samples from station 1, are referred to as base- 
line or control samples; all other samples from outside borrow pits are called 
control samples, and all samples from within borrow pits are designated 
experimental samples. 


IV. SAMPLING AND ANALYTICAL PROCEDURES 


1. Hydrology. 


Surface water temperature and salinity measurements were recorded in each 
sampling period at stations A and B, and on a monthly schedule over the 
duration of sampling at station 1. Temperature was taken using a hand-held, 
mercury bulb thermometer graduated in Celsius degrees. Salinity, in parts 
per thousand, was determined with a Goldberg temperature-compensated 
refractometer (American Optical Co., Model No. 10419). 


2. Sedimentology. 


Sediment samples were collected to determine textural features, statistical 
properties, and carbon chemistry. Textural parameters included weight percentages 
of granules, sand, and silt-clay. Mean grain size, standard deviation (as a 
measure of sorting), skewness, and kurtosis were calculated and interpreted 
according to the system described by Folk (1974). The carbon analyses included 
total carbon, total organic carbon, and total carbonate carbon. 


Collections were limited to surface samples that included the upper 10 
centimeters of sediment. Sediments were collected in standard 8-ounce, screw- 
cap jars; all samples were stored frozen prior to analyses. Detailed 
analytical methods are described by Saloman (1976). 


For textural analyses, sediment samples were sieved at 1-phi intervals 
in nested screens placed on a mechanical shaker. Fraction weights were 
recorded to the closest milligram and tabulated as weight percentages. No 
hydrometer or pipette determinations were required because silt-clay per- 
centages were quite low. Based on grain-size distribution curves, formulas 
introduced by Folk (1974) were used to calculate statistical properties. 
Carbon analyses were made using a Leco 750-100, 90-second carbon analyzer. 


Additionally, divers recorded observations of sediment inside and outside 
the borrow pit at station 1. These observations were made on a regular basis 
during the first postconstruction collection, and in subsequent collections, 
until the study ended. 


3. Benthos. 


At all collecting points, infauna was sampled with a hand-operated plug 
sampler (box corer) that covered a surface area of 1/64 square meter and 
penetrated the bottom to a depth of 23 centimeters (Saloman, 1976). Replicate 
samples were taken at each site, but the number was not always the same for 
each of the three station groups. At stations A and B, four replicates 
composed a sample (preconstruction base-line study of 1974-75). At station 1, 
the first collection contained 32 replicates (19 April 1976), while second and 
third preconstruction samples each consisted of 36 replicates. After dredging, 
however, both control and experimental samples from station 1 each included 
16 replicates. Finally, in the one-time collection at stations 1 to 6, 1 year 
after dredging, control and experimental samples were each composed of 40 
replicates. The decision to take more than 4 replicates in most samples was 
somewhat arbitrary, since sampling to develop a species rarefaction curve 
showed that 4 plugs comprised an adequate qualitative and quantitative sample 
of the nearshore benthos (Saloman, 1976). For reference, a schematic 
representation of the overall sampling plan was prepared to show geographic 
relationships among stations within the study area, landmarks along the shore, 
pertinent transect locations from studies started in 1974, and the sampling 
locations of borrow pits and undredged bottom studied between April 1976 and 
Iumulyy U7 (Csate, Z))¢ 


All benthic samples were taken by scuba divers and sieved on shipboard in 
a 0.3-meter diameter screen of 0.7 millimeter mesh. Material remaining on the 
screen was preserved with 10-percent seawater formalin in standard 2-quart, 
screwcap jars. Rose bengal dye was added to the formalin to stain organisms 
and facilitate their subsequent separation from debris. In the laboratory, 


each collection was resieved under tapwater and all specimens from respective 
samples were stored in 70-percent isopropanol for final sorting, taxonomic 
determinations, and species counts. The 0.7 millimeter screen was used 
instead of a conventional 0.5 millimeter one because the former facilitated 
sieving operations and retained a percentage of infauna that was shown to be 
very nearly equivalent to that sampled by the smaller mesh size. 


As in Saloman's (1976) work, biological data presented here include a 
species checklist and individual station listings that show species occurrence 
and frequency, together with calculations for number of individuals per square 
meter and the Shannon-Weaver index of faunal diversity (H'). Also, as a 
measure of relative species dominance, equitability (J') was computed for each 
station (Pielou, 1975). Two other statistical procedures were also employed. 
The first, Morisita's Index (Morisita, 1959; Bloom, 1981), provided a numerical 
method of comparing faunal similarity between comparable sets of control and 
experimental samples, and was used to develop similarity matrices and classifi- 
cation diagrams that graphically show faunal relationships based on station data 
for diversity and abundance. 


The second procedure, a stability analysis (Bloom, 1980), is a multivariate, 
nonparametric statistical and geometric procedure that converts biotic data 
from control and experimental samples into communities that can be represented 
mathematically. For one representation all base-line and control data were 
used to define numerical characteristics of a preconstruction community cluster 
that has a central point, or centroid, and certain specific spatial limits. In 
the first stability analysis, the distance from the centroid to control and 
experimental samples was used to determine variability among samples from 
undredged and dredged bottoms. In the second analysis, community clusters 
calculated for experimental samples were compared to the preconstruction 
cluster, in postconstruction sequence. When a boundary or an experimental 
cluster met the limit of the preconstruction cluster, faunal recovery was 
accepted. Experimental collections from station 1, where sampling over time was 
done, were the only borrow pit samples used in this analysis. 


V. RESULTS 
1. General. 


The findings in this section are based on the detailed information given 
in Appendixes A to F. Appendix A lists abiotic parameters by station. Appendix 
B is a checklist of all organisms collected at offshore stations from November 
1974 to November 1977. Appendix C contains all biological station data and 
indices of diversity (H') and equitability (J'). Appendix D (Similarity 
Matrices) and E (Classification Analyses and Dendrograms) are both based on 
Morisita's index of faunal similarity. Appendix F is a graphic representation 
of the two stability analyses. The first graph shows comparative variability 
among control and experimental samples when compared with the centroid of a 
community cluster calculated from all base-line and control samples. The second 


is a stability plot for experimental samples from station 1 showing the post- 
construction time lapse before faunal recovery appears evident. 


2. Hydrology. 


Water temperature and salinity data from the 1974-75 sampling at stations 
A and B were compared to data from station 1 sampled during similar months in 
1976-77 (Table 1). Both sets of data show normal seasonal trends in water 
temperature, except for one abnormally low value of 9° Celsius recorded in 
February 1977. 


Salinity was low at stations A and B in August 1975, but salinity during 
other months was 32 parts per thousand or higher, and similar to station 1 
records (Table 1). Appreciable declines in salinity apparently coincide with 
periods of seasonally heavy rainfall. 


3. Sedimentology. 


The influence of dredging on sediment composition was determined by 
analyses of base-line and control samples, compared to samples taken from 
borrow pits. Base-line data came from seasonal sediment collections at 
stations A and B, and from those taken before dredging at station 1 in April, 
June, and July 1976. Control data were available from samples outside the 
borrow pit at station 1, and from samples collected in an undredged bottom at 
stations 1 to 6 in July 1977. Data from experimental samples also came from 
periodic collections at station 1, and from borrow pit collections in the 
single survey in July at stations 1 to 6. 


Textural, statistical, and chemical properties of base-line samples (Table 
2) were used to describe natural features of offshore sediments, since these 
samples were collected in all seasons prior to dredging at eastern, central, 
and western locations within the study area (see App. A). 


a. Texture. Sediment composition was about 99-percent sand, and both 
granules and silt-clay size particles contributed less than 1 percent. 


b. Statistical Properties. Values for mean grain size, standard deviation, 
skewness, and kurtosis classified these sediments as fine sand that is 
moderately well to well sorted, symmetrical to coarsely skewed, and leptokurtic 
(sorted better in the center than at the ends of grain size distribution curves). 


c. Carbon Chemistry. Total carbon content of base-line samples was less 
than 0.30 percent. Carbonate carbon contributed somewhat more to this total 
than organic carbon, indicating that most carbon occurred in the form of shell 
fragments rather than as organic deposits. 


For station 1, when these features were compared to control and experimental 
samples, noteworthy differences appeared only in experimental samples.

The particle-size distribution of sand was below 99 percent in experimental 
samples from September, October, and November 1976, and from January, June, 
July, August, and September 1977. The lowest level (92 percent) was recorded 
in September 1976. Other low values were only in the 97- to 98-percent range. 
Granule-size particles were consistently under 1 percent, but 11 experimental 
samples contained more than 0.30-percent silt-clay. The highest value for the 
silt-clay fraction was 8.1 percent in a sample collected on 21 September 1976. 
Values of more than 1-percent silt-clay were also recorded in another September 
sample as well as in October and November 1976, and again in January, June, July, 
August, and September 1977. 


Mean grain size for experimental samples did not range below fine sand. 
Sorting categories changed for two experimental samples. In the September 1976 
sample, sorting was only moderate; in the May 1977 sample, it proved to be 
extremely poor. For skewness, five experimental samples exhibited an 
uncharacteristic trend that placed them in classifications of fine skewed to 
strongly fine skewed. The single sample classified as strongly fine skewed was 
obtained in September 1976; the others were collected in September and October 
1976, and August and September 1977. Deviation from the normal leptokurtic 
condition was recorded for five experimental samples. Values corresponding to 
mesokurtic were recorded in August 1976, and April and May 1977. Values in the 
very leptokurtic range were recorded in January and June 1977. 


A carbon content percentage greater than the base-line average was recorded 
in 12 experimental samples; however, this number of samples may be low since no 
carbon analyses were made after the June 1977 sampling. The highest recorded 
value was 2.32 percent for the September 1976 sample. Other slightly elevated 
values ranged between 0.31 and 1.21 percent. Among these 12 samples, the pro- 
portion of organic carbon to carbonate carbon was higher for carbonate in 6 
samples, higher for organic in 5, and in 1, the ratio was nearly even. 


Sediment data for control and experimental samples collected at the six 
stations in July 1977 has been tabulated for comparison (Table 2). These 
analyses include only textural and statistical properties; no information on 
carbon chemistry was available. 


At the six stations, granule-size particles were present in only four 
samples, and three of these came from borrow pits at stations 3, 4, and 6. The 
single control sample containing granules also came from station 6, and the 
overall granule distribution was under 1 percent. Sand content was about 99 
percent in all collections. For the silt-clay fraction, only one value was 
considered abnormally high and that was recorded for the experimental sample 
from station 1 (1.36 percent). 


With the one exception of medium sand (station 3, experimental), all samples 
fell into the classification of fine sand. Calculations for sorting showed that 
9 of 12 samples were well to moderately well sorted. Other classifications 
included moderately sorted (station 4, experimental and station 6, control) and 


poorly sorted (station 3, experimental). Skewness values were characteristic 
for five samples (symmetrical to coarsely skewed), and the other seven samples 
fit the strongly coarse-skewed classification and were about equally divided 
between the control and experimental samples. The normal, or leptokurtic 
condition, was found in nine samples. Of the remaining three, the experimental 
sample from station 4 and the control sample from station 6 were mesokurtic, 
while the experimental sample from station 3 was platykurtic. 


Although sedimentological conditions in some experimental samples varied 
from the base-line criteria until late 1977, large variations were confined to 
borrow pit sediments at station 1 within 2 months after dredging. During that 
period, properties which may have been limiting to benthos were high silt-clay 
and organic carbon content. 


Diver reports between 18 August (10 days after dredging) and 4 October 1976, 
stated that the station 1 borrow pit was 3 to 5 meters deep and had very dark 
surface sediments of an extremely soft, silty texture. Initially no surface 
signs of benthic life (burrows, mounds, or trails) were reported. Within the 
next month, sediments had become firmer and sandier, signs of infauna activity 
were conspicuous, crabs and other epibenthos were numerous, and a variety of 
fishes was observed. After 12 months, and on the last dive at station 1 in 
November 1977, divers concluded that borrow pits had filled to within a meter 
of surrounding bottom, and that sediments inside were still finer, darker, and 
less compact than sediments outside, but marine life appeared similar in control 
and experimental areas. 


4. Benthos. 


The checklist of organisms in Appendix B contains about 362 organisms at 
the species level, representing 14 invertebrate phyla and the vertebrate class, 
Osteichthyes (bony fishes). Of this number, Annelida had 152 species (42 per- 
cent), Arthropoda had 108 (30 percent), and there were 69 mollusks (19 percent). 
The remaining 33 species (9 percent) were divided among 11 groups: Cnidaria, 
Platyhelminthes, Nemertinea, Nematoda, Phoronida, Brachiopoda, Sipunculida, 
Echiurida, Echinodermata, Hemichordata, and Cephalochordata. 


Species counts from each station showed a total of 58,068 individuals 
collected. On a percentage basis, more than half were annelids (55 percent), 
19 percent were mollusks, 18 percent were arthropods, Cnidaria and Cephalochordata 
each accounted for 2 percent, Nematoda and Echinodermata both had 1 percent, 
and the other seven groups contained 2 percent, collectively. For the three 
major phyla, species that were numerically dominant in one or more of the base- 
line or control site collections are given in Table 3. 


All station data for richness, quantitative abundance, diversity (H'), and 
equitability (J') were tabulated by base-line, control, and experimental sample 
categories (Tables 4, 5, and 6). Graphic analyses of Morisita's Index and 
stability are given in Appendixes D, E, and F.

a. Richness. The data from base-line and control samples indicate that 
species richness followed an irregular seasonal pattern. Generally, numbers 
of species were lowest in a period between late fall and spring, and showed 
one or more peaks sometime between midsummer and late fall. 


For base-line collections (Table 4), the number of species per sample 
averaged 49 and ranged between 15 (November) and 120 (July). The average for 
control samples was 74 and ranged between 53 (February) and 112 (July). Inter- 
mediate values were recorded for experimental samples. In these collections, 
average number of species per sample was 60; the low, which was only 20, 
occurred in the first collection after dredging; the high was 114, recorded in 
July 1 year later. 


On a date-to-date comparison at station 1 and stations 1 to 6, richness 
data for control and experimental samples (Tables 5 and 6) gave somewhat 
conflicting results. For time-sequence samples at station 1, richness data 
showed incomplete borrow pit recovery as numbers of species prove to be 
consistently higher for controls on every occasion except 1 June 1977. This 
was reflected in the average of 70 and the range between 53 and 89 for control 
samples, as opposed to an average of 51 and a range of 20 to 85 for experimental 
samples. Even so, a degree of recovery was evident at station 1 a few weeks 
after dredging, and richness data for control and experimental samples first 
approximated one another by October 1976. Species recorded in the early stages 
of recovery at station 1 are of special interest because they include survivors, 
migrators, and perhaps the first recruits (Table 7). 


Contrary to indications of the incomplete recovery discussed above, results 
for richness in the one-time sampling at stations 1 to 6 showed that borrow pits 
generally supported more species than undredged bottom at 1 year. This was true 
for stations 2, 4, 5, and 6. Findings at station 1 were contradictory, and at 
station 3, species in experimental collections were outnumbered by those in 
control collections. The number of species in control samples averaged 86 and 
ranged between 5/7 and 112; the number for experimental samples was higher with 
an average of 92 and a range between 80 and 114. 


Even though richness data are somewhat inconsistent, overall they indicate 
that faunal recovery began rapidly and was virtually complete throughout the 
Study area in about 1 year. Data from the one-time sampling at six stations 
support this statement to a greater degree than those from regular time-sequence 
samples at station l. 


b. Abundance. Except for a few anomalies, seasonal cycles of faunal 
abundance coincided with periods of low and high species diversity, i.e., fewer 
animals were recorded in winter collections, and peak numbers generally occurred 
at various times between March and December. In base-line samples, numbers of 
individuals per square meter of bottom averaged 3,883 and ranged from 1,506 
(April) to 7,178 (July). The average for control samples was 3,119, with a 
range betwen 1,408 (July) and 5,576 (August). Experimental samples had an

average of 2,200, with a range between 324 (immediately after dredging), and 
4,037 1 year following dredging. 


Results of periodic sampling at station 1 showed that numbers of individuals 
within the borrow pit first reached control sample abundance in December 1976, 
or about 3 months after dredging had been completed. From that time through the 
next four sampling periods, individuals in experimental samples were more 
numerous than in control samples. In May, abundance values were reversed, then 
again favored the experimental sample in June but remained higher in controls 
until collecting terminated in November 1977. Thus, a pattern of abundance 
indicative of faunal recovery within 3 months did not occur the following sum- 
mer and fall seasons. 


At stations 1 to 6, one-time sampling in July neither confirmed nor refuted 
evidence of recovery from time-sequence sampling at station 1. Numbers of 
individuals were higher in control samples at stations 1, 3, and 4, while 
abundance values were higher in experimental samples at stations 2, 5, and 6. 

A comparison of averages and ranges showed that the average number of individuals 
per square meter was higher for experimental samples. The low for experimental 
collections was well above that of control samples, and the high for experimental 
samples was comparable to the high for control samples. In summary, abundance 
values demonstrated rapid initial faunal recovery in the borrow pits that was 
practically complete after about 12 months. 


c. Diversity (H') and Equitability (J'). For comparable pairs of control 


and experimental samples, species richness and abundance data were converted 
statistically to provide an index of diversity (H') that was used to numerically 
determine degrees of difference between faunal communities in undredged bottom 
and borrow pits. Observed differences were validated for each sample set by 
calculating equitability (J'), which is a mathematical measurement of how evenly 
organisms in a sample are divided among the various species represented (Pielou, 
1975). Used in combination, values of H' and J’ for base-line and control samples 
were regarded normal. For experimental samples, lesser values of H' and J’ were 
attributed to dredging effects, and equal or higher values were considered 
evidence of faunal recovery. In base-line samples, values for both parameters 
were slightly higher in summer months, but control samples at station 1 showed no 
seasonal trend. 


Average values for H' and J' in base-line samples were 2.6 and 0.7 
respectively, with H' ranging from 1.9 to 3.5 and J' ranging from 0.6 to 0.8. 
Average H' in control samples was a little higher than base-line but J' was the 
same and ranges of both were within base-line limits. Among experimental 
collections, average H' was 2.8 and ranged between 1.8 and 3.7. The average for 
J' was the same as for base-line and control samples, but the low was 0.5 and the 
high was 0.8. Lowest values for H' and J' were recorded in January and February, 
and may have been a result of low water temperature as well as dredging. 


When H' and J’ values for control and experimental samples taken on the same 
data were compared, the results showed little regularity. In the series from 


24 


station 1, the first experimental sample to equal or surpass control values of 

H' and J' was collected in October, about 2 months after dredging. From that 
time until November of the next year, only 5 of 14 experimental samples showed 
evidence of faunal recovery. Recovery was demonstrated somewhat better by H' 

and J' data from the six stations sampled in July 1977. At four borrow pit 
stations, experimental samples had the same or higher diversity and equitability 
values than control samples. Also, average H' for experimental samples was 
higher than that for control samples, and averages of J' were the same inside and 
outside borrow pits. 


A review of diversity and equitability results suggests the following: 
(1) the benthos off Panama City Beach exhibited an annual cycle in which species 
diversity and abundance were greater in warm water months than in winter; (2) 
faunal recovery in the borrow pit at station 1 was evident to a considerable 
degree within 2 to 3 months after dredging, and became nearly complete by the 
end of sampling in November 1977; and (3) faunal recovery also occurred within 
1 year of dredging in at least half of the six borrow pits sampled. To further 
test these inferences, sets of biotic data from control and experimental samples 
were evaluated using Morisita's index of faunal similarity and stability analyses. 
Morisita's index was first used to develop similarity matrices (App. D), and then 
to perform a classification analysis that arranged control and experimental 
samples in the form of a dendrogram according to their various degrees of likeness 
(App. E). Two stability analyses were made (App. F). The first shows the amount 
of sample variation among the control and experimental samples when compared to 
the centroid of the statistical faunal cluster calculated from all base-line and 
control data. The second shows time to faunal recovery by plotting experimental 
sample data against the nearest mathematical edge of the same statistical cluster. 


d. Morisita's Index. Similarity matrices were calculated and displayed for 
time-sequence samples from station 1, and for one-time collections at stations 1 
to 6 (App. D). A regular pattern of light cells (no similarity) and dark cells 
(high similarity) was not evident because 45 percent or more of station-to- 
station comparisons in both values had faunal overlap of at least 50 percent. 
For additional clarification, the same data were used to generate a classification 
analysis for presentation as a cluster diagram (App. E). In performing the 
necessary calculations, a Q-mode (normal) analysis was made to show faunal 
relationships on a station-to-station basis; no data transformations were made 
because doing so would obscure the dominant ranking of any faunal elements in 
the samples; and group averaging was selected as the sorting strategy. 


For time-sequence samples, the first five (1 September 1977-experimental to 
10 August 1976-experimental) show very little similarity to any other samples 
and were therefore considered unrelated, or outliers. These outliers include 
two summer-fall experimental samples taken 1 year after dredging, two similar 
winter collections taken about 6 months after dredging, and the first experimental 
sample taken a few days after the dredging. The interpretation here is that the 
two experimental samples 1 year after dredging are as unrelated to other samples 


as the one taken immediately after dredging and the two taken in winter during 
the presumed period of least faunal diversity and abundance. 


The next group is the first cluster and has five samples (1 April 1977- 
experimental to 2 May 1977-experimental). These are related by season (spring), 
and consist of a base-line sample and control and experimental samples collected 
8 to 9 months after dredging. This mixture, and close correspondence between 
control and experimental samples suggests that community recovery has occurred 
within the borrow pit at station l. 


Then there is a single, odd sample with no close associates (1 November 1977- 
experimental), followed by the second cluster which contains eight samples 
(4 October 1976-experimental to 3 October 1977-experimental). Except for the 
two control samples, this group represents the experimental samples in the fall 
during the first 3 months after dredging. 


Cluster three is considered the opposite of cluster two. It has seven 
samples (10 August 1976-control to 2 August 1977-control); five are post-dredging 
late summer and fall control samples; one a preconstruction control sample from 
July; and one a winter experimental sample. 


Cluster four is the largest grouping and contains the next 15 samples (1 
September 1977-control to 1 November 1977-control); 8 of these are fall control 
samples and closely associated with experimental samples taken as soon as 2 
weeks after dredging, as well as in various other months. Here, the indication 
is that recovery at station 1 began very quickly after dredging. 


The fifth and last cluster contains six samples (1 June 1977-control to 
11 July 1977-experimental), which are equally divided among summer control and 
experimental samples taken about 1 year after dredging. Similarities between 
clusters one and five provide substantial evidence of faunal recovery over a 
postconstruction period of 8 to 11 months. 


For the one-time sampling at six stations, control and experimental 
collections all show a high level of faunal affinity and therefore support 
cluster data from station 1 showing a recovery time of 1 year or less. At the 
time these samples were taken, the diagram shows that station location east to 
west along the coast was a greater clustering factor than whether or not a 
sample came from a dredged or undredged bottom. This is not surprising 
considering the daily discharge of estuarine water through West Pass and into 
nearshore waters at the eastern end of the study area. 


e. Stability Analyses. In the first analysis, control and experimental 
samples are represented along the x-axis according to the number of days before 
and after dredging (see App. F). The y-axis is a scale of increasing distance 
from a statistically determined centroid, or midpoint within a community clus- 
ter represented mathematically and calculated from all available base-line and 


26 


control data. This graph shows a large variation occurring in control and 
experimental samples, and at corresponding times, both appear about equally 
distant from the centroid--distance to maximum community stability. In other 
words, control samples did not show close connections to the centroid, nor 

did they follow a seasonal or any other discernible pattern in relation to 

that point. Likewise, experimental samples showed no definite postconstruction 
deviation from the centroid, and followed no subsequent trend that might have 
indicated recovery. In fact, when respective sample distances from the centroid 
were compared in a Mann-Whitney U-Test, it was found that variations among 
control and experimental samples were statistically indistinguishable. The point 
emphasized by this analysis is that faunal variation was a major feature of both 
control and experimental samples. 


In the second graph, the y-axis scale (labeled distance to cluster edge) 
refers to the edge of the statistical community (to a 95-percent confidence 
level) that has the centroid as its midpoint (App. F). The zero point on the 
scale represents the nearest edge of the community, higher positive values are 
increasing distances from the edge, and negative values show that the experimental 
sample falls inside the cluster about the centroid and cannot be statistically 
separated from it. Experimental samples along the x-axis are arranged by day 
number in postdredging sequence. The x-y plots show that an experimental sample 
first touched the edge of the centroid cluster on day 332 (5 July 1977), about 
11 months after dredging was completed at station 1. This intersection of an 
experimental sample with the zero line represents time to faunal recovery. 
However, in several later samples, the plot again falls outside the cluster edge, 
and does not return until October, 14 months after dredging and 1 month before 
sampling ended. This situation may be due to normal sample variation. 


VI. CONCLUSIONS AND DISCUSSION 


Study results indicate several general conclusions related to hydrology, 
sediments, and benthic fauna of borrow pits and undredged adjacent bottom. 
Hydrological measurements included temperature and salinity, recorded quarterly 
at stations A and B in 1974 and 1975, and monthly at station 1 during a 20-month 
period between April 1976 and November 1977. Temperature data showed that 
regular seasonal changes are subject to rather wide year-to-year variations. 
Summer temperature was the most consistent, but in spring, fall, and winter, 
observed yearly differences were on the order of 10° Celsius. In part, 
fluctuations of this magnitude could conceivably mediate events responsible 
for changes in benthic diversity and abundance recorded in base-line, control, 
and experimental samples. 


Salinity was characteristically high (above 32 parts per thousand); however, 
a low value of 26 parts per thousand, recorded in August 1975, showed that the 
study area may at times be influenced by estuarine water masses from St. Andrew 
Bay and perhaps other areas as well (Salsman and Ciesluk, 1978). As with 
temperature, such periodic change could be translated into adjustments in 
community structure. In the case of salinity, however, the effects might be 


21 


more than physiological, as foreign water masses would undoubtedly introduce 
a variety of immigrant organisms and potential community recruits. 


A comparison of sediments from undredged bottom and borrow pits showed 
that most deviations from normal properties appeared in experimental samples. 
Major sedimentological differences could be identified due to accumulation of 
loosely packed, darker, and siltier sediments in the pits shortly after dredging. 
These distinctions became more subtle with time, and by the following year, the 
surface samples (in nearly filled pits) were very similar to sediments on the 
adjacent undisturbed sea floor. When compared to base-line samples, specific 
differences included the following: (1) lower sand content, (2) higher silt- 
clay content, (3) poorer sorting, (4) more finely skewed, (5) more variation 
in both directions from a leptokurtic condition, and (6) higher content of 
organic carbon. 


In the borrow pit at station 1, altered sediment texture was confirmed by 

divers, and bathymetric changes were recorded over time. Depth of the cut was 

3 to 5 meters below the sea floor, and sediment at the bottom initially appeared 
dark, soft, and silty. Within a few months this material was covered by fine 
sand. By the end of sampling in November 1977, the pit had filled to within a 
meter of the surrounding bottom. A final visual impression was that sediments 
were still finer and darker, but no distinction could be made between epibenthic 
and pelagic marine life inside and outside the borrow pit. 


Dredging caused an immediate decline in the bottom community followed by a 
rapid postconstruction recovery that was virtually complete after 1 year. This, 
or even a shorter recovery period of 8 to 9 months, was supported by analyses 
that included: (1) species richness, (2) abundance of individuals, (3) diversity 
and equitability indexes, (4) Morisita's index of faunal similarity, and (5) 
stability analyses. It is important to again note that sampling beyond 1 year 
indicated lack of complete faunal recovery. This may be true, or these samples 
may merely be representative of large natural environmental variations that 
were shown to be an inherent characteristic of the shallow coastal system off 
Panama City Beach. 


On the basis of data presented here, and complementary studies by Saloman 
(1976) and Culter and Mahadevan (1982), it is evident that dredging done at 
Panama City Beach has had no adverse long-term effect on bottom dwelling 
invertebrates, sediments, or water quality either along the shore or in offshore 
borrow areas. Short-term ecological consequences of dredging were shown to last 
only about 1 year, and included only minor sedimentological changes and only a 
small decline in diversity and abundance among bottom dwelling invertebrates. 
This lack of evident protracted environmental alteration is due to factors 
related to physical and biological oceanography within the dredging and disposal 
areas, and to certain engineering features of the beach restoration project. The 
natural factors would include the following regional characteristics: (1) moderate 
to high wave energy capable of eroding and transporting large volumes of sediment 
annually, (2) tidal, longshore, offshore, and storm generated currents that have 


28 


the same, or greater, capability of transporting nearshore sediments, (3) a 
geographic location that is regularly influenced by water masses and marine 
life of estuarine, coastal, and oceanic origins, (4) a native infauna that 
is diversified, abundant, and well adapted to substrate disruption and 
movement, and (5) a fauna that is composed of subtropical and temperate 
species whose active reproductive periods are limited by low water 
temperatures normally recorded in only 1 or 2 winter months. 


As for features of the dredging project, numerous small borrow areas were 
used, instead of fewer larger ones, and they were dredged only to a depth of 
about 5 meters or less. At this level, no strata of silt, clay, or rock were 
uncovered so that sediment type in dredged areas remained very much like 
sediment in undredged areas. Also, dredging occurred in fairly shallow water 
where sediment transport supplied the volume of sand required to rapidly fill 
the borrow pits. In this connection, it is important to mention that because 
of their fast filling rate, and the normally low concentration of suspended 
solids in overlying water, no biologically detrimental quantities of silt and 
clay size particles accumulated in borrow areas off Panama City Beach. If 
anything, during the recovery period, data support the theory that within 
borrow pits a relative decrease in turbulence and a slight increase in organic 
deposits may have been responsible for figures showing a higher diversity and 
abundance of infauna in some dredged areas compared to figures for bottom left 
undisturbed. 


In general, results of coastal restoration studies at Panama City Beach 
agree with findings for similar projects in comparable surroundings (Thompson, 
1973), and along with more recent work (Turbeville and Marsh, 1982), provide 
additional information that can be used both locally and elsewhere to more 
accurately predict and evaluate environmental effects of beach nourishment 
operations. Nevertheless, since each coastal and estuarine area has certain 
unique features, it is important to continue a close association between 
ecological research and coastal engineering. Ideally, the research should be 
conducted to collect base-line data, proceed during all phases of construction, 
and continue after project completion for a sufficient period of time to obtain 
short-term (1 year) and long-term data (2 years or longer). In all instances 
major research emphasis should at least include: (1) factors related to 
geographic and meteorological conditions, (2) sedimentology, (3) water quality, 
(4) hydrodynamics, (5) resident and migratory biota at the bottom and throughout 
the water column, (6) interactions between biotic and abiotic elements, and (7) 
socioeconomic circumstances. By using such a research-oriented approach in 
future engineering projects, many important coastal resources could be protected, 
or even enhanced, and most environmental problem areas would be identified and 
avoided.
