Equipment Used: EM122 12 kHz multibeam, CTD 19+ with OBS, PAR, DO, Chl, ROV, DGPS, Push corer (wh), Niskin bottle, Other, Knudsen 3260, Other

Information to be Derived: Grain size, carbonate content, sediment age, rock types

Summary of Activity and Data Gathered: Covered 4,167 kilometers over 22 days at sea in depths of 135-3,175 meters. Collected 1,821 linear kilometers (6,733 square kilometers) of EM122 multibeam bathymetry and backscatter. Collected 89 files of EM122 water column data over 6 days.Collected 1,270 kms of seismic profile data. 11 ROV JASON (WHOI) Dives, 18 CTDs and deployed 2 Landers. Each ROV dive has video, photos, and numerous physical and bilogical samples. Physical samples are being processed by USGS Woods Hole Sediment Lab and will be logged here once when processing is complete.
