ROV Hercules Climbs Up the Wall of Tutuila Island
Experience a recent dive recap as ROV Hercules climbs up the wall of the north side of Tutuila Island from 996m to 105m depth. The Nautilus team has been working with the National Marine Sanctuary of American Samoa to survey this region for biological communities from fish to corals and sponges, collect rocks for analysis, and sample potentially new species. Learn more about this expedition.
The main objective of this expedition is to acquire baseline information on deep-sea and mesophotic habitat in American Samoa, with a special focus on the National Marine Sanctuary of American Samoa (NMSAS). Within deep-sea habitats, seafloor geology and biological communities will be documented and potentially new species of deep-sea coral and subsamples of rocks will be collected. In addition to seafloor mapping with multibeam sonar, a Lagrangian float will be utilized to capture high resolution photographic images of the mesophotic zone and associated biota.
