Start Date: 2018-09-13
End Date: 2018-09-27
Equipment Used: POS-MV, Van Veen grab sampler, EdgeTech 424 chirp sub-bottom profiler, Boomer, Benthos AQ-4 10-element hydrophone streamer, Reson T20-P, Sensor - SVP
Information to be Derived: bathymetry, backscatter, modern sediment thickness, depth to basement (i.e., top of Pleistocene)
Summary of Activity and Data Gathered: Covered approximately 309 square kilometers of Reson T20P (dual head) bathymetry and backscatter along 387 kilometers of survey lines. Collected (first) 3 days of Boomer data along 115 kms of tracklines. Collected 4 days of 424 Chirp data along 272 kms of tracklines. Collected 17 sediment samples on last day (Sept 26th)
