Oceanographic data and information collected during the EX1703 Howland/Baker PRIMNM and PIPA (ROV/Mapping) expedition on NOAA Ship OKEANOS EXPLORER in the South Pacific Ocean from 2017-03-07 to 2017-03-29 (NCEI Accession 0162616)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 02:58 AM | Dataset Last Updated: September 29, 2025 at 12:00 AM
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.
