Notes on Vent Field Description:
on the eastern ridge of the 11 45'N OSCs; Baker et al. (1994): "The east limb of the 11°45'N OSC hosts several active and inactive hydrothermal vents centered around 11°46'N, although the [temperature anomaly] at 11°42'N suggests that additional vents may also be discharging there."
Notes Relevant to Biology:
serpulid worms
Year and How Discovered (if active, visual confirmation is listed first):
1984 Angus camera (or 1985 Argo video) tow with temperature; 1988 submersible Alvin dive #2004 (need reference to confirm activity)
