In July 1999, DSV Alvin was used to explore the biodiversity at the Patton Seamount. The shallow water community mostly consisted of rockfish, flatfish, sea stars and attached suspension feeders. The community at mid-depths consisted of attached suspension feeding organisms like corals, sponges, crinoids, sea anemones and sea cucumbers. The common fish species were the sablefish and the giant grenadier. The deep water community consisted of fewer attached suspension feeders and more highly mobile species like Pacific grenadier, popeye grenadier, Pacific flatnose and large mobile crabs.
