Notes on Vent Field Description: 
Falloon et al. (1992): "Lavas sampled on the CLSC were associated with active hydrothermal sulphide chimneys occurring at the base of a collapsed caldera structure on the central volcanic axial high."; could this be the same as found on CLSC on cruise SS07/2008? "distinctive hydrothermal plume was detected at the southern end of the southern ridge"; location is close to a plume target on CL6 on cruise SS02/2009 (; Fe & Mn crusts on old lava flows nearby but east of spreading axis (Von Stackelberg et al., 1985)
Notes Relevant to Biology: 
Year and How Discovered (if active, visual confirmation is listed first): 
1990 submersible Mir
