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, Hawaii. 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 dataset contains oceanographic data collected in the waters around Santa Rita, Guam and Saipan. Operations used the ship’s deep water mapping systems, NOAA’s two-body 6000 m remotely operated vehicle, 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 and limited rock and biologic specimen sampling, as well as CTD casts to collect more environmental information at sites of interest. Exploration operations focused on deep-water areas around the Commonwealth of the Northern Marianas Islands (CNMI) and the Marianas Trench Marine National Monument (MTMNM). 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 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 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 and around the Johnston Atoll Unit (JAU) of the Pacific Remote Islands Marine National Monument, the U.S. EEZ around Hawaii, and the high seas during transit to and from JAU. Operations included the use of the ship’s Acoustic Doppler Current Profilers (ADCP), Scientific Computer System (SCS) data acquisition system designed for oceanographic and fisheries applications, and the ship’s high-bandwidth satellite connection for continuous real-time ship-to-shore communications. Underway CTD and XBT casts were also conducted, as well as use of OER’s 6000 m two-body ROV Deep Discoverer and Seirios.
