Field Activity 2012-024-FA

Identifier 2012-024-FA
Purpose Map the CT River from the river mouth north towards Essex, CT; geophysical mapping will be followed by sampling
Location Connecticut River, Old Saybrook, Essex, Connecticut, United States, North America
Summary 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.
