Notes on Vent Field Description: 
intracontinental rift; although assumed active, listed as unconfirmed because not observed visually; Ishibashi and Urabe (1995): "Prior to 1970, the number of known seafloor hydrothermal mineral deposits was only one" [the Atlantis II Deep site described by Miller et al. (1966)]; largest known seafloor massive sulfide deposit; brine pool; Note: Koslow (2007) textbook says that the first evidence for seafloor hydrothermal activity was discovered at 2000-m depth in the Red Sea in the 1880's by the Russian R/V Vityaz
Year and How Discovered (if active, visual confirmation is listed first): 
1965 "confirmed" hot brine and cored seafloor, but see Table 1 in Miller et al. (1966) for historical measurements
