USGS Coastal and Marine Geology Program

Field Activity Details for field activity 2009-018-FA

Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Walter Barnhardt

Affiliate Investigator(s): Bill Schwab

Information Specialist(s): William Danforth

Data Type(s): Biological Field Study: Experiments, Biological Field Study: Surveys, Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Seismics: Sub Bottom Profiler, Sonar: Multibeam, Sonar: Single Beam, Visual Identification: Species ID

Scientific Purpose/Goals: 1) Map sea floor geology in shallow water (0-10 m depths) at very high-resolution by using swath bathymetry, acoustic backscatter, and sub-bottom profiling. 2) Test and calibrate sea floor mapping equipment (resolution and repeatability of swath bathymetric mapping and real-time kinematic navigation).


Start Port/Location: Pocasset, MA

End Port/Location: Pocasset, MA

Start Date: 2009-10-01

End Date: 2009-10-30

Equipment Used: Grab sampler, SeaBOSS, SWATHplus-M 234 kHz, Real Time Kinematic GPS, Echosounder, Submetrix Sidescan sonar, EdgeTech 424 chirp sub-bottom profiler, Multibeam swath bathymetry, Digital camera, Knudsen CHIRP Sub-bottom Profiler

Information to be Derived:

Summary of Activity and Data Gathered: We mapped the sea floor in Red Brook Harbor in depths from ~2 meters to 10 meters using our SEA SwathPlus 234 kHz interferometric sonar, EdgeTech 424 chirp seismic profiler, Knudsen 3.5 kHz 3200 seismic profiler, and kinematic navigation techniques. Fully overlapping swath bathymetric data was collected, as well as concurrent seismic reflection profiles. After the geophysical data were collected, we deployed our SEABOSS system and occupied 50 stations, collecting 47 sediment samples, still photos, and video. We also tested out the Benthos C3D system for a day, occupying 5 lines that were previously surveyed with our SwathPlus system for comparison.

Notes: Will use several sub-bottom systems: Knudsen, EdgeTech 424 CHIRP. Will NOT tow a sidescan; use backscatter from SubX.
