Summary of Activity and Data Gathered: This cruise was visited by two different Hurricanes (José and Maria). Original departure port (Morehead City, NC) was moved to Norfolk, VA and departure date was moved from 11 Sep to 12 Sep. Rode out Hurricane José in Morehead City, NC 16-19 Sept. Cruise was terminated on 22 Sept (6 days early) because of approaching of Hurricane Maria. Complete Cruise details available from NOAA OE website for Cruise https://oceanexplorer.noaa.gov/explorations/17deepsearch/welcome.html. NOAA Survey ID = PC-17-05 Total Ship Trackline=1,200 kms Pisces bathymetry (ME-70) =44 km Pisces seismic profile (Knudsen 3260)= 800kms Sentry Dives=3 Sentry bathymetry (Reson 7125)=145 kms (depth and backscatter) Sentry sidescan seismic profiles (EdgeTech 2200M)-145 kms Sentry--continuous bottom photographs CTDs=7 6 sediment samples from monocore on CTD

Notes: Multibeam data (depth,backscatter,water column) will be collected via Simrad ME 70 hull mounted sonar on NOAA Ship Pisces. In addtion AUV Sentry (WHOI) will collect same multibeam data with a Reson 7125 sonar. Chirp SBP collected via Setnry AUV. Imagery from AUV.
