Notes on Vent Field Description: 
Winckler et al. (2010, in review): "We use the distribution of helium isotopes along an oceanic transect at 67°S to identify previously unobserved hydrothermal activity in the Pacific sector of the Southern Ocean.", "We identify three complete ridge segments, a portion of a fourth segment and two isolated locations on the Pacific Antarctic Ridge between 145°W and 175°W (representing ~540 km of ridge in total) as the potential source of the newly observed plume."
Notes Relevant to Biology: 
Year and How Discovered (if active, visual confirmation is listed first): 
2009 plume only
