Geophysical Mapping of Oyster Habitats in a Shallow Estuary; Apalachicola Bay, Florida
Survey PlatformsTwo survey platforms were used to collect geophysical data in Apalachicola Bay (fig. 2). The R/V Rafael, a 6.3 m outboard-motor propelled vessel with an ~ 1.5 m draft, was used to survey sections of the bay where water depths exceeded 2 m during two cruises (March 14-April 13, 2005, and May 29-June 27, 2006).
During June 3-27, 2006, IRIS, an Autonomous Surface Vehicle (ASV), was used to survey sections of the bay where water depths were between 0.75 and 2 m. IRIS is a 2-m long, battery-powered remote vehicle that surveys pre-programmed tracklines. Bathymetric, sidescan-sonar, seismic-reflection, and navigation data were all collected from both platforms.
