Start Port/Location: Old Saybrook, CT
End Port/Location: Old Saybrook, CT
Start Date: 2012-09-15
End Date: 2012-09-23
Equipment Used: SeaBOSS, Camera - B/W video, SEA SWATHplus-M 234 kHz, DGPS, 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.
