Collect bathymetry to initialize hydrodynamic model and acquire new seismic data to connect with existing offshore lines. This data will be used to help evaluate impacts of shoreface engineering activities on system ecogeomorphology.
Field activity was completed on June 15, 2024. Shoreface singlebeam bathymetric data out to 4 m depth were acquired across the lengths of Wallops, Assawoman, and the emergent Gargatha islands, as well as along the northern tip of Metompkin Island and within the north and south channels of Gargathy Inlet. Adjacent MBES data were also acquired beyond 4 m depth, filling in bathymetry between areas covered by shallow singlebeam data and offshore MBES data acquired from earlier surveys. CHIRP seismic lines oriented parallel, perpendicular, and obliquely to shore were also acquired in tandem with MBES data. Additionally, seven sediment samples were acquired from Assawoman and Wallops islands, including one sample taken from an exposed marsh platform on the beach of Assawoman Island and six samples taken from the anthropogenically created lagoon and inlet complex on northern Wallops Island.

SubFAN identifiers:
24BIM01 = WVR1/Shark
24BIM02 = WVR2/Chum
24BIM03 = 512i Chirp Sled navigation/bathymetry
24BIM04 = Sallenger MBES and 512i Layback navigation
All seismic acquisition will be collected under the larger FAN 2024-310-FA regardless of system.
22-ft Twin Vee
This boat has a carrying capacity of up to 1500 pounds and up to 7 people and a shallow draft (9 inches empty). This boat's cat hull design results in a smoother ride in choppy water, at the expense of a slightly deeper draft. This boat is powered by two Yamaha 70hp motors.
