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.

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 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 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.

EM302 multibeam data will be collected 24 hours a day and will be gathered over previously unexplored regions. Data will be used to better understand the bathymetry of the Puerto Rican trench and allow reconnaissance of the region prior to the ROV cruise. Multibeam operations within 5 miles of land in priority area 1 will be conducted during daylight hours. XBT casts will be conducted at an interval defined by prevailing oceanographic conditions, but not to exceed 6 hours. XBT data will be used to correct the sound velocity of the multibeam data. Additionally, EK 60 (single beam) and sub-bottom profile data will be collected 24 hours per day.

This dataset contains oceanographic data collected from NOAA Ship OKEANOS EXPLORER from 2022-04-04 to 2022-04-28. Data acquisition from shipboard sensors includes navigational data, meteorological data (altimetry, conductivity, depth, dew point, fluorescence, oxygen, pressure, relative humidity, relative wind speed, salinity, sound speed, sound velocity, temperature, true wind, turbidity, water temperature, wind, wind direction, wind speed), vehicle data (ROV time to surface, traction winch data, line rate data), and Profile Data (ASVP and XBT).

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 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 on little or unknown areas of the continental slope between Rhode Island and Chesapeake Bay. The major driving objective during these dives was to conduct engineering trials of the ROV and focused outreach events. Dives in the area of Lindenkohl canyons were devoted to ROV engineering trials, dives in the area of Washington Canyon were focused on exploration, and dives at the head of Norfolk Canyon and the mid-Atlantic gas seep site focused on outreach operations. ROV dives were conducted mostly during the day, while CTD casts and acoustic mapping occurred when the ROV was on deck. Data acquisition from shipboard sensors includes navigation data, meteorological data (wind, air temperature, relative humidity, barometric pressure), and oceanographic data (thermosalinograph, remote temperature probe, sound velocity probe, bathythermograph).
