Notes on Vent Field Description:
Coastal Alaska; "Armed with a thermometer and bottles to collect water samples, Jewett cautiously approached one of the hydrothermal openings. The water above the vent was 100 degrees Fahrenheit" (http://www.uaf.edu/aurora/archives/fall-2008/sfos/aurora_f2008_sfos.pdf); Global Volcanism Program profile, accessed 1 June 2015: "Hot springs and fumaroles occur along a steaming beach at the SE coast"; Aleutian Arc transition from oceanic to continental at 164 W
Notes Relevant to Biology:
The divers found Beggiatoa, sulfur dependent bacteria, growing directly above the vents. A few feet away the divers found the same creatures as in other areas — sea urchins, anemones, sponges and other organisms — seemingly unaffected by the high water temperature and gases. The divers discovered what they believe to be a previously unknown family of kelp in the same area. The new kelp is called golden V. It was found in only two places in the region of the hydrothermal vents (http://www.uaf.edu/aurora/archives/fall-2008/sfos/aurora_f2008_sfos.pdf)
Year and How Discovered (if active, visual confirmation is listed first):
