Other ID: none

Status: Completed

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

Funding Program(s):

Principal Investigator(s): David Foster

Affiliate Investigator(s): Chris Sherwood

Information Specialist(s): Seth Ackerman

Data Type(s): Sonar: Interferometric, Sonar: Multibeam, Sampling: Geology, Location-Elevation: Navigation, Seismics: Sub Bottom Profiler, Imagery: Photo, Imagery: Video

Scientific Purpose/Goals: Map the CT River from the river mouth north towards Essex, CT; geophysical mapping will be followed by sampling

Vehicle(s):

Start Date: 2012-09-15

Start Port/Location: Old Saybrook, CT

End Date: 2012-09-23

End Port/Location: Old Saybrook, CT

Equipment Used: SWATHplus-M 234 kHz, Grab sampler - Van Veen , DGPS, Seismic reflection, EdgeTech 424 chirp sub-bottom profiler, GoPro camera, Real Time Kinematic GPS

Information to be Derived: Grain size analysis;Sea floor map;Bathymetric maps;

Summary of Activity and Data Gathered: About 227 line-km of digital Chirp sub bottom and 234 kHz interferometric sonar data were collected. 100 percent bathymetric coverage was achieved and sonar backscatter were processed and mosaicked in the field. Eighty seven sample stations were occupied, 73 grab samples were collected, 66 stations included video and photographs of the bottom.
