Oceanographic data collected during the EX1302 (Ship Shakedown, Patch Test and Exploration, NE Canyons) expedition on NOAA Ship OKEANOS EXPLORER in the North Atlantic Ocean from 2013-05-13 to 2013-06-06 (NCEI Accession 0108363)
Between May 13 and May 18, shakedown operations will: ensure all scientific sonars are in good working order after dry dock operations; assess noise reduction modifications to the sub-bottom profiler; update software and install new multibeam acquisition computer; conduct multibeam patch test; and calibrate the EK60. After May 18, the new 6000 meter ROV will be put through rigorous engineering tests, calibrated, and exercised. Video acquisition procedures and pathways will be tested on the new system, both in terms of broadcast quality video clips as well as testing the new system to record the outgoing video streams. Ship personnel will be trained on video acquisition and image generation protocols.

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 6,000m 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 occurred 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.
Oceanographic data collected during the EX1404L1 (Shakedown and Mapping, NE Seamounts) expedition on NOAA Ship OKEANOS EXPLORER in the North Atlantic Ocean from 2014-08-09 to 2014-08-30 (NCEI Accession 0121584)

Multibeam, single beam, and subbottom sonar data will be collected 24 hours a day and XBT casts will be conducted at an interval defined by prevailing oceanographic conditions, but not to exceed 3-4 hours. EX1404L1 will perform baseline characterization mapping (multibeam, splitbeam, subbottom) of New England Seamount chain in preparation for EX1404L3. During transiting to and from seamounts, exploration mapping will include areas of poor quality from existing ECS data and gaps in ECS data.
Oceanographic data collected during the EX1301 (Ship Shakedown and Patch Test Exploration, NE Canyons and Seamounts) expedition on NOAA Ship OKEANOS EXPLORER in the North Atlantic Ocean from 2013-03-18 to 2013-04-05 (NCEI Accession 0107211)

Multibeam and singlebeam mapping operations were conducted 24 hours a day throughout the cruise. Sub-bottom profile mapping was conducted 24 hours a day at the discretion of the CO. XBT and/or Underway CTD (UCTD) sound velocity casts in support of multibeam sonar mapping operations were conducted at an interval defined by prevailing oceanographic conditions, but not to exceed 6 hours. All data was fully processed according to standard onboard procedures and is archived with the NOAA National Centers for Environmental Information.
