Field Activity 2008-024-FA

Identifier 2008-024-FA
Alternate names R-24-08-ME
Purpose Re-mapping of pockmark field to determine morphological change (if any) and to refine sub-bottom structure.
Location Penobscot River, Penobscot Bay, Belfast Bay, Maine, United States, Gulf of Maine, North America, North Atlantic;
Summary Seismic reflection system failed after three days due to software problems (SB Logger). Very frustrating. Swath bathymetry and backscatter from sidescan sonar: 8 days of data collection, 340 km of tracklines, water depths 3-90 m; Seismic reflection profiles: 3 days of data collection, 109 km of tracklines; Sound velocity profiles: 15.
