Notes on Vent Field Description: 
first deep-sea vents discovered; axial volcanic high; van Andel and Ballard (1979) geological map is for 86 11'W to 86 07'W, i.e., does not include Rose Garden; map of active vent fields in Ballard et al. (1982) is for 86 17'W to 85 58'W; maximum temperature 22 C in Ballard et al. (1982); Clambake I and II (named after photos taken in 1976), Mussel Bed (1979), Oyster Bed (1977), Rose Garden (1979, not active in 2002), Garden of Eden (1977, still active 2005), Rosebud (2002); Shank et al. (2012): "The lack of biota and presence of vitreous, unsedimented lobate lava flows observed at the Rosebud diffuse vent field (86.2°W) suggests that there may have been an eruption at this site after 2005 when this site was last visited."; note: Garden of Eden is approx. 6 naut. miles east of Rose Garden (00 47.7'N, 86 07.7'W) and was considered a separate vent field in Hessler and Smithey (1984)
Notes Relevant to Biology: 
Riftia tubeworms, Mytilidae, Vesicomyidae, Bythograeidae, enteropneusts
Year and How Discovered (if active, visual confirmation is listed first): 
1977 submersible Alvin; 1976 plume and photographs of clam shells did not confirm activity (note: Rose Garden is used here as the name of the vent field, but Rose Garden vent site itself not discovered until 1979)
