During the fourth dive of the Seascape Alaska 3 expedition, the team was able to verify the presence of a gas seep first discovered in seafloor mapping data collected during the first Seascape Alaska expedition, finding bubbles from four active seeps, in situ methane hydrates, methane-derived authigenic carbonates, cemented worm tubes, dense clusters of very healthy chemosynthetic tubeworms that likely buried additional active seeps, Vesicomyidae clams, and a variety of additional marine life.
