Summary of Activity and Data Gathered: Phase I Geophysical Survey: 8 total survey days with Submetrix, Knudsen, EdgeTech. Lost 5 days to rebuilding starboard engine on RAFAEL. Data collected: Submetrix bathymetry/backscatter, EdgeTech sidescan, Knudsen seismic reflection. Phase II Ground Validation: Occupied 100 target stations in 3 survey days, recovered 56 sediment samples. Data collected: bottom video, bottom stills, sediment samples (grain size).
