American Samoa Leg 1

E Mamana Ou Gataifale I
Muti-Vehicle Exploration – 18-day expedition to explore the dynamic seafloor and water column habitats surrounding Vailulu’u Seamount, in addition to midwater and other unexplored deep-sea habitats in the region.

American Samoa Leg 2

E Mamana Ou Gataifale II 
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. 

Howland and Baker

Howland and Baker Islands lie just north of the equator, about 1,800 miles southwest of Hawaiʻi. The islands are low-lying, sandy coral islands ringed by narrow fringing reefs and surrounded by the deep ocean. The US exclusive economic zone around Howland and Baker represents one of the least explored regions under US jurisdiction.

Jarvis

Mapping Hawaii to American Samoa
Ongoing repair to a ship system has changed plans for the expedition, postponing the ROV exploration portion of this expedition within the Jarvis Unit of PRIMNM. The expedition will now evolve into a mapping transit leg to American Samoa. 

Lebuu’s Voyage I – Palau

 OET will lead this 11-day expedition to gather seafloor mapping data and explore the seafloor with remotely operated vehicles to illuminate deep sea habitats around Palau.

Lebuu’s Voyage II – Palau

 11-day expedition will continue exploring Palau National Marine Sanctuary (PNMS) to understand seafloor features and the biodiversity that call deep sea habitats around Palau home.

Mapping and Water Column Exploration Offshore Palau

This expedition takes us from Palau to Guam for 17 days of mapping. Beginning in late November in Koror, Palau, and ending in December in Apra, Guam where it will stay for the winter.
