Bubbling Vents and Colorful Chimneys of Volcanic Vailulu'u Seamount
On the hunt for bubbles, chimneys, and stunning hydrothermal vent features, our team returned twice to survey Vailulu'u Seamount, the only submarine volcano in the National Marine Sanctuary of American Samoa. 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.
