2023 Expedition Season

Join Ocean Exploration Trust for our 2023 E/V Nautilus season as we embark on eight months of scientific exploration in the waters of the Central and Eastern Pacific Ocean, mapping unsurveyed seafloor and characterizing deep-sea habitats through detailed ROV observation, as well as integrating emerging technologies. Expeditions will be planned and executed around the priorities of the science and resource management community to close knowledge gaps in our unfolding understanding of our changing ocean planet. Mapping and ROV operations will primarily be conducted in unexplored areas, thus contributing directly to the US National Strategy for Ocean Mapping, Exploration, and Characterization, the development of a global high-resolution seafloor map by Seabed 2030, and the UN Decade of Ocean Science for Sustainable Development. The 2023 Nautilus expedition season is sponsored by NOAA Ocean Exploration through the NOAA Ocean Exploration Cooperative Institute, Ocean Networks Canada, the Office of Naval Research, and the Bureau of Ocean Energy Management.
