Notes on Vent Field Description:
Lupton et al. (1999): "Dive targets at ... 16.6 S, ... were new sites which were visited by ALVIN for the first time in 1998/99. The selection of these new sites was based on camera tows conducted in the 1980's (Holler) and also by water column plume surveys conducted in 1993... Although single exploratory dives at ... 16.5 S, ... failed to detect any hydrothermal venting..."; Alvin dive 3324 log observed inactive vent deposits and sampled crabs
Notes Relevant to Biology:
crabs
Year and How Discovered (if active, visual confirmation is listed first):
1993 plume only; 1998 submersible Alvin did not confirm activity
