Notes on Vent Field Description:
as distinguished from South Chamorro Seamount which is a serpentinite mud volcano at 13 47'N; located within U.S. Marianas Trench Marine National Monument (http://www.fws.gov/marianastrenchmarinemonument/); "Once Deep Discoverer reached the top of the crater rim, where there were jagged boulders and a steep drop, D2 descended northward to the crater floor where we found MORE hydrothermal activity; one chimney structure there was venting ~48°C fluids. There were several discrete chimney structures, and the ROV got some great close-ups of them as the vehicle flew north across the crater floor, which was generally smooth and ash-covered." (Okeanos Explorer ROV Dive Summary, 2016)
Notes Relevant to Biology:
"As the ROV made its way upslope, there were some unusual fauna: amphipod families on “sticks” that they constructed; polychelid lobsters (these living fossils are rarely seen; however at least ten were observed during this dive); and 2 species of demosponges." (Okeanos Explorer ROV Dive Summary, 2016);
Year and How Discovered (if active, visual confirmation is listed first):
