Notes on Vent Field Description:
Fig. 3 in Auzende et al. (1996); note: Fig. 1D in Charlou et al. (1996) labels this location inactive; note: plume not detected here in 1993 (Baker and Urabe 1996)
Notes Relevant to Biology:
Auzende et al. (1996): "Around the 17 10'S area, animal colonies are present on the axis with the large mytilid bivalve Bathymodiolus occurring within the lava fissures. Alvinellide worms, crabs, and empty tubes of Riftia were observed and sampled on the active site"
Year and How Discovered (if active, visual confirmation is listed first):
1993 submersible Nautile
