Summary
|
|
This field season marked the second year of surveying in
|
|
Apalachicola Bay. The goal of the mapping project was to provide an
|
|
updated map of the distribution of oyster beds in the bay.
|
|
Continuous coverage sidescan sonar imagery and bathymetric data were
|
|
used to achieve this goal, and high-resolution chirp profiles were
|
|
used to define the geologic framework upon which the oyster beds are
|
|
set. The bay is shallow (average depth 2.5 m), and the crests of
|
|
most of the oyster beds are in water depths less than 1 m.
|
|
Consequently the entire area could not be surveyed using the RAFAEL.
|
|
IRIS, the newly acquired ASV, was used to map the shallow areas.
|
|
This was the first use of this system, and it proved quite
|
|
successful. This year s field operation was conducted during late
|
|
May and June. The RAFAEL collected data during 25 of the 29 day
|
|
field program and IRIS collected data during 14 days. Aboard RAFAEL
|
|
RTK GPS navigation, Klein sidescan sonar imagery, Submetrix
|
|
interferometric bathymetry, and chirp subbottom profiles were
|
|
collected in digital form along 1492 km of trackline. IRIS
|
|
collected RTK GPS navigation, Edgetech sindscan sonar imagery,
|
|
single-beam bathymetry, and chirp subbottom data in digital form
|
|
along 148 km of tracks. From the two platforms data (all in digital
|
|
form) were collected along 1640 km of survey lines.
