Notes on Vent Field Description:
hydrothermal plumes virtually continuous between 17 20' and 18 40'S; Fig. 7c in Wright et al (2002); not explored by Nautile in 1993 or Shinkai 6500 in 1994; Haymon and White (2004) separate the 17 26'S, 17 34'S, 17 37'S, and 17 44' active fields on 3rd order ridge segments
Notes Relevant to Biology:
Alvin dive 3296 log includes: "Anemones, Bacterial mats, Non-vent fish, Other worms, Sea cucumbers, Sea stars, Sponges, Tube worms, Vent fish, Snails/Limpets"
Year and How Discovered (if active, visual confirmation is listed first):
1996 Argo II towed video; 1993 plume only; 1998 submersible Alvin
