Identifier 2023-310-FA
Alternate names Marine Corps Base Hawaii Reefense Chirp, MBES, Imagery, Sediment
Purpose Bathymetry mapping and geologic assessment offshore of Ft. Hase, Oahu in support of efforts to construct an artificial coral reef offshore of Marine Corps Base Hawaii.
Location Kailua, HI, United States, Pacific Ocean
Summary Collected 84 seismic tracklines, bathymetry, and imagery data.
Info derived Seafloor depth, chirp geophysical data, polecam imagery. Diver-collected sediment grabs and push cores.
Comments Entries for this field activity are based on entries from Field Activity 2022-334-FA. Marcuson will depart survey on 5/10 or 5/11. Diver will be substituted in. Imagery will be taken using PCMSC Pole Cam.
