This dataset contains oceanographic data collected in the deep water areas around Wake Island and along transits from Guam to Kwajalein. Operations will use the ship’s deep water mapping systems, NOAA’s two-body 6000 m remotely operated vehicles, CTD rosette, and the ship’s high-bandwidth satellite connection for real-time ship to shore communications. Daytime ROV dives were planned most days, as were a few dedicated mapping transit days. ROV dives included high-resolution visual surveys and limited rock and biologic specimen sampling. Mapping operations were conducted overnight when the ROV was on deck and CTD casts were taken to collect more environmental information at sites of interest. This expedition helped establish a baseline of information in the region to catalyze further exploration, research, and management activities.

This dataset contains oceanographic data collected in the deep waters in and around Papahānaumokuākea Marine National Monument (PMNM) in the Northwestern Hawaiian Islands and Johnston Atoll. The primary goal for this cruise was to collect baseline data and information to support priority NOAA science and management needs. The 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 deepwater marine protected areas in the Pacific. Operations for this cruise included the 24-hour collection of ship navigation data and scientific computing system data, which comprises of meteorological and oceanographic sensor data, as well as water column profile data. The ship also conducted daytime ROV dives that focused in depths between 250 and 6,000 meters, and included high-resolution visual surveys and biological/geological sample collections. Opportunistic CTD rosette operations were completed to collect more information about the environmental parameters at ROV dive sites where collecting the data is considered important to understanding the physical or chemical properties of the overlying water column.

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.

This dataset contains oceanographic data collected in deep water areas south and southeast of the flower Garden Banks National Marine Sanctuary (FGBNMS), including Keathley Canyon and adjacent parts of the Sigsbee Escarpment, and areas on the West Florida Escarpment southwest of Tampa. Daily ROV dives were conducted with full shore-based science participation. Evening and nighttime mapping and CTD operations were also conducted and focused in depths less than 500 m. Most of the operations, including the transit, were conducted within the 200nm exclusive economic zone (EEZ) maritime boundary of the United States of America.

This dataset contains oceanographic data collected in Honolulu, Hawaii. This cruise included shakedown and engineering tests for both the ship and the Office of Ocean Exploration and Research (OER), and Global Foundation and Ocean Exploration (GFOE) ROV and telepresence systems. Operations used the ship’s deep water mapping system (Kongsberg EM302 multibeam sonar, EK60 split-beam fisheries sonars, ADCPs, and Knudsen 3260 chirp sub-bottom profiler sonar), NOAA’s two-body 6000m remotely operated vehicles (ROVs Deep Discoverer and Seirios, and the ship’s high-bandwidth satellite connection for real-time ship to shore communications. The ship conducted 24-hour operations consisting of daytime ROV dives, with ship shakedown items and evening/nighttime mapping operations and DP testing.

This dataset contains oceanographic data collected in the vicinity of the Deepwater Horizon site, Mississippi Canyon, and Green Canyon. Deepwater areas in the vicinity of the Flower Garden Banks were also explored. Daily schedules were split between daytime ROV operations (<4000 m) and nightly multibeam surveys. Nightly operations also included CTD casts. The initial portion of leg III focused on flux experiments using the ROV to ground-truth acoustic data. This expedition identified and explored the diversity of benthic habitats in the region, located and characterized submerged cultural resources and assessed their eligibility for the National Register of Historic Places, and improved capabilities to explore the water column.

This dataset contains oceanographic data collected in the US EEZ surrounding Puerto Rico and the US Virgin Islands. Operations explored largely uncharted deep-sea ecosystems and seafloor, and investigated unknown and poorly known areas, including the Puerto Rico Trench, Muertos Trough, Mona Passage, and the Virgin Islands Trough. This leg featured some of the deepest remotely operated vehicle (ROV) dives ever conducted in the region and collected critical deep-water environmental data that will improve ecosystem understanding and inform federal and local resource managers. ROV dives were conducted during the day, to a maximum operating depth of 6000 m, while CTD casts occurred when the vehicle was on deck.

This dataset contains oceanographic data collected in areas off the West Florida Shelf, around Desoto Canyon, in the vicinity of the Deepwater Horizon site and Mississippi Canyon. Daily schedules were split between daytime ROV operations (<4000 m) and nightly multibeam surveys. Nightly operations also included CTD casts and water-column experiments. This expedition identified and explored the diversity of benthic habitats in the region, located and characterized submerged cultural resources and their eligibility for the National Register of Historic Places, expanded tests of acoustic methods to detect gas seeps and measure flux, and improved capabilities to explore the water column.
