American Samoa is the southernmost U.S. territory, cen­tered in the South Pacific, 2,300 miles southwest of Hawaiʻi, and 1,500 miles northeast of New Zealand. It is home to the cradle of Polynesia’s oldest culture. The E Mamana Ou Gataifale II expedition will explore deep-sea habitats around American Samoa in collaboration and consultation with the National Marine Sanctuary of American Samoa (NMSAS) and other partners, providing data needed from deep ocean areas to inform resource management and conservation priorities.

This expedition will use E/V Nautilus’ remotely operated vehicles and Woods Hole Oceanographic Institution’s autonomous underwater vehicle (AUV) Sentry to expand the amount of exploration possible within this 20-day expedition. AUV operations will provide important data for interpretations of seafloor biological density and diversity, enhancing mission planning and opportunities to survey cultural heritage sites. Exploring these sites will also provide a gateway to captivate and engage broad audiences across American Samoa and the Pacific Island Region through telepresence-based exploration. Specific cruise objectives will continue to be refined as we work with local community and scientific partners.

This expedition is funded by NOAA Ocean Exploration, NOAA Office of Marine and Aviation Operations Uncrewed Systems Operations Center, and the Bureau of Ocean Energy Management via the Ocean Exploration Cooperative Institute (OECI) with additional support from Woods Hole Oceanographic Institution (WHOI), Air/Sea Heritage Foundation, and other partners.
