Notes on Vent Field Description: 
southeastern side of Axial Seamount; note: 1986 submersible Pisces IV Dive 1730, may have been preceded by camera tows; Embley et al. (1990): "Although no high-temperature vents have been discovered along the SRZ, this area seems to contain the most areally extensive venting"; area affected by eruption and lava flow in 1998 - Embley et al. (1999): "partial or total burial of pre-existing mature vent communities"; axial seamount (volcano), hotspot influence
Notes Relevant to Biology: 
NotProvided
Year and How Discovered (if active, visual confirmation is listed first):
