The "Thérèse mound" specimens were preserved along with their associated fauna, which included zoanthids, abundant amphipods and what looked like a naked mollusc species coiled around the branches (to be confirmed). The manipulator arm on "Victor 6000" was used to collect Alcyonacea on "Victor 6000" dives 6 and 7.
