Notes on Vent Field Description:
Baker et al. (1994) plots an active vent at approx. 11 24'N observed in deep towed photo survey, corresponding to Tow-Yo TH14; axial high on ARGO-RISE Fig. 1; however, this location is not reported by ARGO-RISE (1988); Baker et al. (1994): "Hydrothermal plume distributions define three categories: intense and continuous (...11°05'-11°27'N)"; also observed low temperature vents on Alvin Dive 3934 in 2003
Notes Relevant to Biology:
Alvin dive 2225 log includes "Anemones, Basalt lava, Clams, Inactive vent deposits, Lo temp vents, Mussels, Other worms, Sea cucumbers, Sea stars, Snails/Limpets, Sponges, Tube worms, Vent fish"
Year and How Discovered (if active, visual confirmation is listed first):
1990 submersible Alvin; 1988 submersible Alvin dive #1994 (need reference to confirm activity)
