This dataset contains oceanographic data collected in Pago Pago, American Samoa. Operations focused within several marine protected areas and included the use of the ship’s deep water mapping systems (Kongsberg EM302 multibeam sonar, EK60 split-beam fisheries sonars, ADCPs, and Knudsen 3260 chirp sub-bottom profiler sonar), and the ship’s high-bandwidth satellite connection for real-time ship to shore communications. Focused mapping areas occurred in the Pacific Remote Islands Marine National Monument (PRIMNM) (U.S.) in the vicinity of Kingman Reef and Palmyra Atoll, and Jarvis Island, as well as in the Phoenix Islands Protected Area (PIPA) (Republic of Kiribati).

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.

This dataset contains oceanographic data collected in Apia, Samoa. Operations were conducted within several marine protected areas and included the use of the ship’s deep water mapping systems (Kongsberg EM302 multibeam sonar, EK60 split-beam fisheries sonars, Knudsen 3260 chirp sub-bottom profiler sonar, and Teledyne Acoustic Doppler Current Profilers), and XBT casts in support of multibeam sonar mapping operations, OER’s 6000 m two-body ROV Deep Discoverer and Seirios, and the ship’s high-bandwidth satellite connection for continuous real-time ship-to-shore communications. Operations were planned in Tokelau, Kiribati’s Phoenix Islands Protected Area (PIPA), the Howland and Baker unit of the Pacific Remote Islands Maine National Monument (PRIMNM), National Marine Sanctuary of American Samoa, and Samoa.

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.
