Oceanographic data and ROV dive-related multimedia and information collected during the EX1504L2 (CAPSTONE: NWHI Exploration Leg II) expedition on NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from 2015-07-31 to 2015-08-22 (NCEI Accession 0131885)

This dataset contains oceanographic data collected in and out of Pearl Harbor. Operations used NOAA Ship Okeanos Explorer's deep water mapping system, NOAA's two-body 6000 m remotely operated vehicles (ROV's Deep Discoverer and Seirios), CTD rosette, and the ship's high-bandwidth satellite connection for real-time ship to shore communications. Daytime ROV dives were conducted and included high-resolution visual surveys, instrument recoveries, and limited rock and biologic specimen sampling. This expedition is part of a three-year Campaign of Expeditions (Campaign to Address Pacific monument Science, Technology, and Ocean NEeds or CAPSTONE) focused on exploring the deepwater marine protected areas in the Pacific and around the Northwest Hawaiian Islands.
