During mapping operations, our multibeam system also collects water column backscatter or data about what is in the water column between the surface and the seafloor. When mapping Daikoku Seamount, we found a very active hydrothermal plume that eventually helped us target the ROV dive transect. We believe that this plume was composed of the large amounts of bubbles coming from the seafloor that we saw during the ROV dive.
