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. Most of the mapping areas pursued during this cruise were never mapped with modern sonar before. Mapping activities focused on three primary areas, (1) some potential underwater cultural heritage sites south of Oahu, (2) the Necker Island area within the Papahānaumokuākea Marine National Monument (PMNM), and (2) the Karin Seamount Chain near Johnston Atoll within the recently expanded Pacific Remote Islands Marine National Monument (PRIMNM).

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.

During EX-15-03L2, multibeam data was collected 24 hours a day and XBT casts were conducted at an interval defined by prevailing oceanographic conditions, but not to exceed 6 hours. Additionally, EK 60 (single beam) and sub-bottom profile data was collected 24 hours per day. Data was only collected in foreign waters where clearance was granted. If no permit was obtained, all data collection systems were shut down in those foreign waters. All multibeam data was fully processed according to standard onboard procedures and was archived with the National Geophysical Data Center.

Oceanographic data collected during the EX1505 (October 2015 Transit: Honolulu, HI to Alameda, CA) expedition on NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from 2015-10-05 to 2015-10-16 (NCEI Accession 0138039)

Throughout this cruise, multibeam data was collected 24 hours a day and XBT casts were conducted every 6 hours. Additionally, EK 60 (split beam) and sub-bottom profile data were collected 24 hours per day, with subbottom profile data collection at the discretion of the CO. Onboard multibeam data processing was minimal due to limited staffing. Daily or bi-daily multibeam products were produced according to established shipboard SOP and sent to shore through established shipboard SOP. Onshore mapping physical scientists monitored data quality, cruise progress, and discovery potential. Raw EK 60 and subbottom data was sent to the shoreside repository through established shipboard automated archival procedure.

Multibeam, single beam, and subbottom sonar data will be collected 24 hours a day. XBT casts will be conducted regularly for multibeam calibration. The ship's Scientific Computing System (SCS) will monitor and collect oceanographic, navigation, and meteorological data throughout the cruise.

Oceanographic data collected during the EX1607 (CAPSTONE Wake Island PRIMNM (Mapping)) expedition on NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from 2016-08-25 to 2016-09-11 (NCEI Accession 0156614)

This dataset contains oceanographic data collected in and around the Wake Island Unit of the Pacific Remote Islands Marine National Monument (PRIMNM). Operations focused on collecting seafloor mapping data over several seamounts within the Wake Island Unit of PRIMNM, and conducting targeted mapping exploration transits between the start and end ports and the working grounds. This expedition helped establish a baseline of information in the region to catalyze further exploration, research, and management activities. Operations began in Kwajalein, Marshall Islands and concluded in Honolulu, Hawaii, and included 24 hour/day mapping using the ship’s deep water mapping systems and high-bandwidth satellite connection for real-time ship to shore communications.

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.
