Oceanographic data collected during the EX1602 (Mission System Shakedown/CAPSTONE Mapping) expedition on NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from 2016-02-12 to 2016-02-17 (NCEI Accession 0145342)

Operations used the ship's deep water mapping systems (Kongsberg EM302 multibeam sonar, EK60 split-beam fisheries sonars, Knudsen 3260 chirp sub-bottom profiler sonar, Teledyne RDI Workhorse Mariner and Ocean Surveyor ADCPs), NOAA's two-body 6,000 m remotely operated vehicle (ROVs Deep Discoverer and Seirios) system, CTD rosette, and the ship's high-bandwidth satellite connection for real-time ship to shore communications. ROV dives were mostly conducted during the day, while CTD casts, and multibeam, singlebeam, and sub-bottom acoustic mapping occured when the ROV was on deck. Exact locations of discrete ROV dives and mapping operations were to be determined during the cruise as results of engineering and shakedown tests were evaluated and once weather and operational constraints were factored in.
