Other ID: R-24-08-ME
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Walter Barnhardt
Affiliate Investigator(s): Joe Kelley, University of Maine; Laura Brothers, University of Maine
Information Specialist(s): Brian Andrews
Data Type(s): Imagery: Photo, Location-Elevation: Navigation, Seismics: Sub Bottom Profiler, Sonar: Sidescan, Sonar: Sound Velocity, Sonar: Interferometric
Scientific Purpose/Goals: Re-mapping of pockmark field to determine morphological change (if any) and to refine sub-bottom structure.
Start Port/Location: Belfast, ME
End Port/Location: Belfast, ME
Start Date: 2008-09-16
End Date: 2008-09-25
Equipment Used: EdgeTech 424 chirp sub-bottom profiler, Klein 3000, Digital camera, Real Time Kinematic GPS, SEA SWATHplus-M 234 kHz, Sensor - SVP
Information to be Derived:
Summary of Activity and Data Gathered: 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.
