AN UNDERWATER TELEVISION AND SIDE SCAN SONAR SURVEY
OF BOTTOM SEDIMENTS AT SEVERAL AREAS
WEST OF TAMPA BAY, FLORIDA
1.0 INTRODUCTION
The Environmental Protection Agency (EPA) conducted an underwater tele-
vision reconnaissance survey of seven areas west of Tampa Bay, Florida
(Figure 1). One area, identified as Site 4, was covered in intense detail;
a second area, identified as the Control Site, was covered in considerable
XB detail. Two other areas, identified as Site A and B, were covered in lesser
^ detail. Three sites suggested by the State of Florida were also briefly examined to
>!A assess their bottom characteristics. The location and sampling runs in these
vj sites is also shown in Figure 1. The method of analysis for the three State
M sites is similar to that of Site 4 and the Control Site.
The survey, conducted from EPA's OSV ANTELOPE during the period April
>4j 21 - 27, 1983, obtained data on the physical characteristics of the bottom
"f sediments, and supplemented information either previously or concurrently ob-
tained at the study sites. In conjunction with the underwater television survey,
EPA conducted a aide scan sonar (SSR) survey of the dredged material disposal
sites. The underwater television provides a direct visual and highly detailed
assessment of a relatively narrow track (several meters wide) of the bottom
beneath the ship's course; SSS provides lower resolution acoustic "pictures"
of the bottom over areas 50 to 100 m wide (depending on instrument settings) to
either side of the ship's course. This report provides a general analysis of
the SSS records obtained at Sites 4, A and B and compares the acoustic records
with results of the underwater television survey analysis, where appropriate.
The merging of these two sets of data with the ship's course provides an essen-
tially complete description of the surficial sediment type and percent distri-
bution within .the study areas.

2.0 METHODOLOGY FOR VIDEOTAPE ANALYSIS
Ten six-hour videotapes were provided to JRB Associates by EPA for anal-
ysis. The tapes were viewed with a Panasonic VMS videotape recorder on a 22"
cpldr. television monitor. Loran-C coordinates of the survey vessel position
were recorded on the ship and displayed in real tine on the color monitor,
providing a capability to plot and confirm features that were noted on the
EPA-provided field charts. These charts, containing the ship's track super-
imposed on a Loran-C coordinate grid, were used in conjunction with the video-
tape viewing. A set of rulers was devised to correspond to the scale of
Loran-C grid. These were used to accurately chart the vessel's course according
to the Loran-C coordinates seen on the television monitor. Since the scale
was different at every site, a new set of rulers was made for each site.
Prior to starting a videotape, the VHS counter was zeroed and the tape
number was entered on a videotape log. The log ultimately contained VHS
footage, Loran-C coordinates, identification of bottom types and pertinent re-
marks. The entire log is presented as Appendix A to this report.
Upon viewing the videotape, it became apparent that several bottom types
were present. On a subjective basis, six different bottom types were
identified. A bottom type determination was made after several meters of
unchanging bottom were encountered. .For example, at Site 4, Tape 1, flat
sandy bottom (Type 1) was present from VCR count 452 to 829 (See videotape log,
*
Page A-l). Generally, no other bottom type was seen in the field of view.
Periodically a brief stretch (1 meter) of another type would occur. This
was not recorded as a change in bottom type. A change in bottom type was
recorded when once again several meters of essentially unchanging bottom was seen.
When the bottom changed, the VHS footage, Loran-C coordinates and bottom
type were recorded on the videotape observation log. Frequently, Loran-C
coordinates and VHS footage were recorded to accurately chart the vessel's
course and the associa:ed bottom type. The bottom type identified at the
previous Loran-C coordinate is considered present until a change is indicated.
The respective bottom types were recorded in a coded form on the field charts
along the vessel track according to Loran-C coordinates. The combination of
coded charts, videotape log and videotapes constitute an effective system for
-------
viewing desired portions of the underwater television mission.
Percent distribution of bottom types along the vessel track was calcul-
ated for Site 4, Control Site and State Sites X, Y, and 2. This was done by
measuring the length (in cm) of each bottom type with a planimeter a minimum of
three times. The average length was used to calculate percent distribution
of the total track. Only clearly identified bottom was used in the calculation.
An additional statistical analysis was conducted on Site 4. The purpose
of the statistical evaluation was to determine the percent area covered and to
correct for error. To establish the statistical vessel coverage of Site 4; the
following methodology was employed. The. OSV ANTELOPE made 22 runs northwest to
southeast and 22 runs northeast to southwest, creating a cross-hatched grid
pattern. Since the vessel made passes in approximate one-quarter-mile intervals,
the site area was divided into one-eighth-mile square units, which resulted in .
256 total units. The original coded vessel track was laid over the grid. By
using a unit area smaller than the vessel track, i.e., one-eighth-mile versus
one-quarter mile, we were able to determine the area not covered by the vessel
track. The grid units were numbered from 1 to 256 starting in the top left hand
corner proceeding across the site from west to east and continuing the pattern
from the left margin.
Units with only one bottom type present were recorded as 100% of that type.
Where multiple tracks were present, each type was measured with a planimeter a
minimum of three times. The average length of each type was- recorded and percent
distribution was calculated. Units where no type was present or where a type
intersected the corner were recorded as not covered. Consequently, data along a
vessel track was collected for 82.8% of Site 4 (212 units covered divided by
256 = 82.8% coverage).
Bottom type percent distribution was totalled for the remaining 212 units.
Percent distribution of bottom type identified on the whole vessel track was then
calculated.
212 Units Covered (%) 256 Total Area (%)
Type 1 - 52.4 43.4
Type 2 - 2.7 2.2
Type 3 - 29.9 24.7
Type 4 -' 14.2 11.7
Type 5 - 1.0 0.8
Type 6 - No Type 6 was identified at Site 4
Not Covered 17.2
-------
It Is reasonable to believe that a bottom type is consistent throughout
a grid unit; however, it Is possible that other bottom types may be present in
an area classified as one type. For this reason, examination of the side scan
sonar record is imperative to provide an acoustical picture of the remainder of
the grid unit. Section 4.0 discusses the SSS analysis and conclusions.
Finally, Site 4 and the Control Site were compared according to percent
distribution of bottom types and sampling coverage. Site A and B were only
generally reviewed to note changes from previous studies.

3.0 VIDEOTAPE ANALYSIS
3.1 CHARACTERISTIC BOTTOM TYPES
Six bottom types were identified from the videotapes. The surveyed areas
were assigned one or more of these categories according to the code described
below. Basically, Types 1, 2 and 3 are variations of sand bottom. Types
4 and 5 indicate to what degree the bottom is inhabited. Type 6 connotes a
mixture of bottom types. Due to the variable factors involved in underwater
videotaping, i.e., ship speed, field of view, distance of camera from the bottom,
etc., this classification system represents only visually identified changes in
the appearance of the bottom.
Type 1. Sandy bottom -
—•*•-••*) flat to slightly rippled sand, typically
fine quartz and shell sand. Sand dollars and dark "algal" patches
were commonly observed on this type of bottom. Minimal other marine
life seen.
-------
Type 2.. Small scale sand ripples^- (AA) small sand ripples, approximately
1" - 3" high, coarser sand granules, darker in appearance than sandy
bottom. Little marine life seen.
-------
Type 3. Large scale sand ripples •'&*£&• Larger sand ripples, approximately
6" - 8" high, with trough between ripples approximately 21 - 5'
wide. Coarse sand observed as continuous crests and as broken, inter-
mingling crests._ Little marine life.seen.
-------
Type 4. Scattered Populated bottom - (•H|) Sandy bottom with silty, dimpled
appearance. Stretches of scattered and diverse bottom cover. Organisms
were randomly distributed over the observed areas.
,
'1:
-------
Type 5. Densely populated bottom -
Minimal sandy areas. Stretches of
dense bottom cover. Organisms heavily distributed over the observed
areas.
TvPe 6* Mixed bottom _ (flBflM) Areas characterized by rapidly changing bottom
types; frequently alternating from Type 1 to Type 3 and back to Type 1.
The'most common mixed bottom was Types 3 and A.

3.2 SITE CHARACTERISTICS .
3.2.1 Site 4 - Site 4 is an EPA proposed dredged material disposal site. It is
2
a 4 nmi area, centered at Loran-C coordinates 14139.0 - 44745.0. Twenty-two runs
were made in Site 4, eleven along the NW to SE axis and eleven along the NE to
SW axis. An additional run was made around the periphery of the site. The
peripheral run at Site 4 was done at night and the quality of that videotape is
~ji
not as good as that of daytime runs. Generally, however, the bottom seen was
similar to the adjacent bottom area with the site boundary. However, the night
coverage presented a smaller field of view, making 'it more difficult to accurately
identify bottom types.
The distribution of bottom types is 'illustrated in Figure 2. The predom-
inant bottom type in Site 4 was sandy bottom (Type 1). Over 48.5 percent of the
total area charted was of this type. Highest concentrations of sandy bottom
occurred in a swath from the northeast quadrant across the center into the SW
quadrant. The vast majority of this area was devoid of visible life. Sand
dollars were occassionally seen, often associated with scattered algal patches,
which were common in Type 1 bottoms. Fishes, crabs and starfish were occasionally
seen.
Large scale sand ripples (Type 3) also accounted for a large portion of this
site. Thirty-two percent of the total area was composed of this type. The
sand ripples ranged from distinctive widespread crests with shell hash and
silt visible in the troughs, to intermingled broken ripples. Visible bottom
organisms were uncommon in these areas. Scattered populated bottom comprised
16.9 percent of Site 4. These areas were located primarily in the northwest and
southeast corners of the site. Only 0.8 percent of the total site could be char-
acterized as densely populated bottom (Type 5).
3»2.2 Control Site - The Control Site is located southeast of Site 4 cen-
tered, at Loran-C coordinates 14130.0 - 44700.1. Generally, the quality of
the videoupes was very good. However, a NE tb SW run along Loran-C coor-
dinate 44697.3 was difficult to distinguish due to cloudy water. Six runs
were made through the site; three across the NE-SW axis and three across the
Ntf-SE axis.

-------
The predomonant bottom type at the Control Site was scattered populated
bottom (Type 4). About 47 percent of the total charted area was of this
type. High concentrations of Type 4 occurred in the northeast and northwest
quadrants. Only 0.3% of the site could be characterized as densely populated
bottom (Type 5). The southwest quadrant was primarily flat sand (19.72 of
the total area of the site), whereas the southeast quadrant was largely mixed
bottom (Type 6). In the southeast sector, the bottom area changed frequently,
every several meters. The general pattern was from flat sand (Type 1) scat-
tered populated bottom (Type 4) to large scale sand ripples (Type 3) back to
flat sand (Type 1). Figure 3 illustrates the distribution of bottom types of
the Control Site.
3.2.3 Site A - Site A is a previously designated dredged material disposal
site (Figure,1). A single run was conducted from the SE to the NW corner of
this site. The quality of this videotape footage is poor, due to cloudy water
and frequent raising of the camera sled to avoid boulders. The topography is
generally flat sand with intermittent areas of debris. Some of the rocks appear
to have been colonized by soft corals. No other bottom life was visible. Scat-
tered areas of large scale sand ripples were also observed.
3.2.4 Site B - Site B is also a previously designated dredged material disposal
site (Figure 1). A single run from NW to SE was recorded in this site.
Throughout the coverage, the videotape picture appeared cloudy, as if the camera
lens were fogged. The bottom areas identified were mainly populated with large
soft corals (approximately 2 1/2 feet high). Grass-like corals were also
present. Depth records indicate about 30 feet of water at this site. Flat sand
(Type 1) and sporadic large scale ripples (Type 3) composed the remainder of the
site. Frequent sand dollars were seen at this site; there were approximately
50 organisms per 18 meters of distance covered.
3.2.5 State Site X - Three runs were recorded in State Site X. The entire
bottom area was flat sand (Type 1 ) frequented by sand dollars. State Site X
is located in deeper water (average 105 feet) than any other site examined in
this area. Mo dark patches or mobile life forms were seen.
13
-------
-------
3.2.6 State SiteY - Two runs were conducted in this site. The most striking
feature was the dense populations of sand dollars. A rough count yielded 80
per 18m. The bottom type was predominantly Type 1-flat sand (91.3%) with inter-
mittent large-scale coarse sand ripples (8.7%). Life was sparse in these
areas. Average water depth was 96 feet. . .
3.2.7 State Site Z - Two runs were conducted in this site. State Site Z
was primarily composed of large scale sand ripples, scattered populated bottom,
and densely populated bottom (Types 3, 4 and 5) (approximately 39%). The
remaining portion was predomoninantly large scale sand ripples alone. A very
small part of this site was flat sand. Average depth was 102 feet. Distri-
bution of bottom types of State Sites X, Y and Z are shown in Figure 4;
percent distribution in Table 1.
3.3 RESULTS
The Control Site was not studied as intensively as Site 4 (6 runs vs.
23 runs, respectively). However, given the patterns identified in each site,
a general comparison can be made. Table 2 shows the percent distribution of
bottom types at the Control Site and Site 4. Site 4 contained a greater per-
centage of flat sandy bottom (Type 1) (48.5%) and large scale sand ripples
(Type 3) (32.2%) than the Control Site, (19.7% and 13.4%, respectively). No
mixed bottom (Type 6) was identified at Site 4. The densely populated bottom
(Type 5) at Site 4 was approximately equal to that at the Control Site (0.8%
vs. 0.3%, respectively). However, the Control Site had a greater area of
consistently populated bottom than Site 4 (47.1% vs. 17.7%). More variation
in bottom types throughout the southeast quadrant of Site 4 was noted than in
the control site. Both sites were located in approximately 70 feet of water.
A comparison of the initial track study of Site 4 (Table 2) and the stat-
istical analysis of Site 4 (Page 4) shows a decrease in the percentage of Type 4
(16.9% to 11.7%). This was due to more representative calculations produced by
the statistical analysis. No significant change was noted regarding Type 5.

4.0 SIDE SCAN SONAR RECORD ANALYSIS
*
The SSS records provided by EPA were reviewed and all annotations on the
records were recorded in a log. Approximately half of the SSS records reviewed
are of poor quality because of a stylus problem, later .corrected by the instru-
ment's manufacturer. These SSS records do not warrant detailed study, but are
useful for a general assessment of the reflectivity of bottom sediments.
(Typically, a sand bottom exhibits high reflectivity and results in a darker
SSS record. Clay and silt bottoms are less reflective than sand, and tend
to absorb the acoustic energy; thus, they provide a relatively lighter SSS
record). Using the log, the ship's positions were plotted on working copies of
the field charts. Each SSS lane consisted generally of two positions, the
start and end of the survey run. Occasionally, one or more additional positions
were recorded on the SSS chart between start and end points. Selected portions
of the SSS tracks were then merged with bottom sediment type determined during
analysis of the underwater videotape. Representative SSS records for Sites A
and B are provided for reference purposes (Charts 4 and 5); the generally poor
quality of the records of Sites A and B preclude further analysis.
4.1 SITE'CHARACTERISTICS
4-1-1 Site 4 - Figure 5 shows the approximate location of the selected SSS
records in relation to the ship's track and bottom sediment types determined
from the videotape analysis of Site 4. Chart 1 portrays a relatively featureless
bottom with no significant variations in acoustic reflectivity; this record is
characteristic of a sandy (Type 1) bottom. This SSS record extends 50 meters
2
to either side of the ship's track and represents about 0.33 km in area.
Chart 2 represents a portion of the line shown in Figure 5. This SSS
record extends 100 meters to either side of the ship's track, and depicts the
transition from a combined Type 3 (large scale sand ripples) and Type 4 .
(scattered populated) bottom to a Type 1 (flat sandy) bottom. The darker por-
tions of the record are more reflective, and therefore represent fla. rand.
The ripples noted in the darker portion of the record are large-scale sand waves.
The transition from the flat sand to a softer clay or silt bottom is quite
abrupt, and occurs in an estimated distance of 30-50 feet.

Chart 3 depicts a similar transition over the portion .of the ship's
track identified in Figure 5. The sand ripples are again noted in the
darker portions of the records. There is a rather weak transition between
/
the large-scale sand ripples and scattered populated bottom (Types 3 and
4) with respect to the featureless flat sand bottom (Type 1).
4.1.2 Site A - A representative SSS record extending 100 meters to either
side of the ship's track for Site A is shown in Chart 4. The bottom is
relatively hard and representative of small and large scale sand ripple bottoms
(Types 2 and 3).
4.1.3 Site B - A representative SSS record for Site B is shown in Chart 5.
It depicts a combined hard and soft reflective bottom and is in general agree-
ment with the underwater television observations.

5.0 CONCLUSIONS
Two previously designated and one proposed dredged material disposal
sites were studied to assess the bottom sediment characteristics. A fourth
area, to be used as a control, was also studied. Approximately 80 nautical
miles of underwater television videotape were viewed and analyzed. Six
bottom types were identified and their relative distribution calculated.
Bottom types and other pertinent observations were compared between the
Control Site and Site 4. Sites A and B and State Sites X, Y and Z were only
generally reviewed.
Site 4 had over twice the percent distribution of flat sandy bottom
sediments (Type 1) compared to the Control Site (48.5% vs. 19.7%). On the
other hand, scattered populated bottoms (Type 4) are approximately .three times
more prevalent at the Control Site than at Site 4 (46.8% vs. 16.9%). Large
scale sand ripples (Type 3) were over twice as frequent at Site 4 than at the
Control Site (32.2% vs. 13.4%).
The methodology developed for the analysis of the videotapes provides an
efficient means for reducing a large data base. The data base ponsisting of the
tapes, videotape viewing log and associated charts provides an efficient
method of reviewing specific bottom types and other pertinent features.
ri. >
The SSS records for Site 4 showed good correlation with the underwater
videotape analysis of bottom sediment types, and in particular the trans-
•
itional areas between the different bottom types. The SSS provides much
greater aeral coverage of the bottom than can be obtained with underwater
television. The utilization of both systems in concert provides a useful
method for analysis of bottom sediments over relatively large areas.
