Notes on Vent Field Description:
INDEX-SATAL 2010 cruise ROV "Little Hercules" dives Ocean Explorer press release with videos at: http://www.noaanews.noaa.gov/stories2010/20100712_underwatervolcano.html; Makarim et al. (2010): "sources of the detected vent plumes in the northern and southwest part of the summit in 1800-1900 m depth. In southwest part of this summit chimney, drips of molten sulfur were observed in the proximity of microbial staining."; Butterfield et al. (2010): "The vents seen on the south slope appear identical to vents detected by camera tow and reported by McConachy et al. (2004)."
Notes Relevant to Biology:
stalked barnacles, shrimp, limpets, polynoid scale worms, alvinellid polychaetes, brachyuran and galatheid crabs, vesicoymid-like clams; Butterfield et al. (2010): "The visually dominant vent fauna is a stalked barnacle that covers much of the chimney surfaces."
Year and How Discovered (if active, visual confirmation is listed first):
2003 towed video, CTD/transmissometer, and dredge
