Notes on Vent Field Description: 
Baker et al. (1994): "Hydrothermal plume distributions define three categories: intense and continuous (8°48'-8°58'N, …", "Lonsdale and Spiess (1980) conducted a cursory deep-tow survey between 8 37' and 8 50'N in 1977 but found no evidence of hydrothermal venting in 900 sets of bottom photographs. By contrast, the plume studies clearly reveal several strong vent sites between 8 42' and 9 N,"
Notes Relevant to Biology: 
Year and How Discovered (if active, visual confirmation is listed first):
