SUMMARY ANT) CONCLUSIONS

This project was an effort to produce accurate
detailed maps showing the location, size, and
distribution of submerged grassbeds in Bogue and Core
sounds in Carteret County, North Carolina. The use of
conventional aerial photography was considered by the
authors to be an effective and economical method of
mapping the large areas involved.

Several conditions were noted during this study
which must be considered when attempting to take aerial
photography of submerged grass beds. Tide stage should
be as low as possible; visibility must not be reduced by
haze or weather; frames must be generously overlapped to
help prevent "blind spots" in the photo coverage caused
by sun reflection and to aid in location and horizontal
control. Ground truthing is also a very critical element
of the mapping of submerged grass beds, not only to verify
interpretation of the photography, but to confirm
location and density data. ("Ground truthing" means
verification of photo-interpretation by visiting or
sampling the actual site photographed.)

The base photography for this mapping was scaled
aerial natural color photography flown by the North
Carolina Department of Transportation. This photography
was analyzed for locations of submerged grass beds, which
were then field checked by investigating personnel.
Biological information and consultation was provided by
the Fisheries Management Section of the North Carolina
Division of Marine Fisheries. Once identified and
checked, these grass beds were mapped on U.S. Geological
Survey 7 1/2 minute series quadrangle sheets. The areas
in acres and the North Carolina Grid Coordinates of the
center of each bed were then computed by the Land
Resources Information System.

19,458 acres of grass beds were identified and
mapped within a total water area of 104,840 acres. These
beds are shown and described in the maps and tables on
pages 5 through 84 of this report.

This study has shown that conventional aerial
photography, when taken under proper conditions of tide
and visibility, and coupled with ground truthing, is a
practical cost-effective means of mapping submerged grass
beds within shallow estuarine lagoons such as Core and
Bogue sounds.

PUEPOSE AND OBJECTIVES

Submerged marine grass beds of eelgrass (Zostera
marina) and shoalgrass (Halodule wrightii) are necessary
to the survival of several commercially and ecologically
important species of marine life in Core and Bogue sounds
and their adjacent waters. These species include the bay
scallop, pink and brown shrimp, blue crab, and ten or more
species of fish. Other marine species, as well as several
species of waterfowl, also utilize these grass beds.
Submerged grass beds provide nursery areas to many of
these marine species, and are critical to their survival
and propagation.

These grass beds are fragile and sensitive to the
silting and excavation activities associated with the
construction and maintenance of submerged pipelines. Oil
spills or pipeline leakage present a great hazard to
these grass beds and to the marine life which inhabits
them. The mapping of these unique biological areas will
provide an accurate base in order to mitigate damage to
them from siltation, excavation, or oil spillage. Having
precise locations of these beds will allow the erection
of physical barriers (silt screens, containment
apparatus, etc.) to reduce or block the flow of silt,
sediment, or spilled oil into them. These maps, when used
with wind, tide, and current data, will aid in plans for
quick response to oil spills by identifying those areas
which should be given protection priority. Pipeline
routes may be aligned or re-aligned to mitigate damage to
these beds caused by construction, maintenance, or by
accidental leakage or rupture.

A major objective of this project was to determine
the suitability of conventional color aerial photography,
at scales of 1000 feet or less per inch, as base mapping
information for submerged grass beds. Other objectives
included determination of suitable conditions for taking
this photography, methods of producing accurate final
maps, and techniques for accurate computation of acreages
and location coordinates.

PROCEDURES

Aerial Photography

The base aerial photography for this project was flown May 12-22,
1981, by the North Carolina Department of Transportation, Photogrammetry
Section. A Wild-Heerbrug RC-10 aerial camera with a 6-inch focal length
lens was used, with Kodak // 2445 Aerocolor Negative Film with haze
filters. The base prints provided from this flight were 9-inch by 9-inch
natural color contacts, color-corrected and balanced, at a scale of 1000
feet per inch. These base prints were not rectified. A frame overlap of
60% was used to avoid "blind spots" caused by sun reflection.

Interpretation and Identification

Initially, interpretation consisted of constructing mosaics from the
color contact prints. Clear acetate sheets were overlaid on each mosaic,
and grass beds an shoreline details were traced in black ink onto the
acetate overlays. Known horizontal control stations were added to the
overlays to be used for location and in the rectification of the interim
maps. During this mapping, groundtruthing was used to confirm densities
and to confirm or delete questionable areas.

Densities were delineated in three classes: scattered, moderate,
and dense. Scattered indicates grass beds in which the grasses cover
less than 207o of the bottom area within the bed. Moderate indicates
coverage of 20% to 75%, and coverage greater than 75% is labelled dense.
It should be noted that these densities will vary seasonally. No attempt
was made to determine species mix or percentage in the grass beds.

Mapping

Photographic negatives were made of the acetate overlays. These
negatives were then used to produce rectified prints at a scale of 2000
feet per inch (1:24,000) to match the U. S. Geological Survey 7 1/2 minute
quadrangle sheet series. The mapped grass beds were then transferred to
the USGS 7 1/2 minute quad sheets by direct tracing, producing a series of
master maps .

Computations

These master maps were then sent to the Land Resources Information
Service, Division of Land Resources, North Carolina Department of Natural
Resources and Community Development. Data on grass beds were entered into
the LRIS computer system using a Talos 660-B digitizer and a Data General
Eclipse S-230 computer. This system provided printouts giving the acreage
of each grass bed and the North Carolina Grid Coordinates of the center of
each bed.

RESULTS

The final maps and data tables are included in this report in pages 5
through 84. The conventional aerial photography method enabled the
authors to identify and map 623 grass beds totaling 19,458 acres within a
total water area of 104,840 acres. The authors feel that the results were
most satisfactory in this area and that the same good results may be
obtained in similar shallow estuarine areas if certain conditions are met.
These conditions are discussed on page 85 below.

DISCUSSION

The maps that follow in pages 5 through 84 are drawn on portions of
USGS 7 1/2 minute quad sheets. North is oriented at the top of all maps
except the index sheet. Each map is faced by a table showing pertinent
data on each bed or portion of bed shown on that map. In all cases, data
given applied to each bed in total. The reader should not add data from
sheet to sheet where portions of beds are shown.

On each map grass beds are shaded to indicate grass density according
to the following key:

REC0MENDATI0N3

The authors recoiTunend the use of conventional color aerial
photography as a base for mapping submerged grass beds in shallow coastal
waters. Since the accuracy of interpretation depends on the clarity of
the photographs, certain conditions should be met:

(1) Atmospheric conditions must be clear with minimal haze.

(2) Haze filters should be used to prevent bluish tints.

(3) Frames must be generously overlapped to avoid blind spots
caused by sun reflection, and photography should not be taken
when the sun angle is very high or very low.

(4) Wind-caused wave action should not be present.

(5) Tide stage must be at or near its lowest ebb. In areas
where muddy bottoms may cause turbidity on ebb tides,
observations should be made to determine the period when water
clarity is greatest.

(6) The time of year should be chosen to match peak growth of
the beds .

(7) Altitude should be low enough to provide a negative scale
of not more than 1000 feet per inch (1:12,000).

(8) Accurate rectification of the master maps is critical to
the accuracy of the final data.

While this technique worked very well in the shallow waters (less
than six feet at low tide) with sand bottoms, this method would not be
suitable for deep or turbid areas. Since the grass beds mapped in this
project occur on shallow sandy bottoms, water depth and turbidity
presented little problem during this study.

The successful mapping of the grass beds in Core and Bogue Sounds by
conventional aerial photography suggests many other projects which can be
performed by the same method. Obviously, periodic remapping would give
valuable information on the permanence of these grass beds, serving to
monitor their increase or decline. Photography flown during various
seasons of the year would provide information on seasonsal growth
variations. Additional projects in other shallow estuaries similar to
Core and Bogue Sounds would provide additional base maps.

The North Carolina Office of Coastal Management and the U.S. Army
Corps of Engineers have already used information from this study in permit
decisions on channelization projects in the mapped area. The N. C.
Division of Marine Fisheries also used this information to determine areas
where certain types of bottom-disturbing fishing gear should not be
allowed. The Division of Marine Fisheries has also expressed interest in
periodic mapping of these grass beds to monitor the effects of the use of
certain types of fishing gear on the.

The total cost of this project was approximately $16,800. Repeating
the project in the same area with the same coverage would cost less--
perhaps $10,000 to 12,000--because of the one-time special costs for
basemaps and software for the present, pilot project. The use of the Land
Resources Information Service (LRIS) computerized mapping system was
clearly cost-effective and also had the advantage of preserving the
mapping data in easy-to-retrieve and easy-to-manipulate form.
