Notes on Vent Field Description:
position very approximate; depth rounded from Bird (2003) model step; Maia et al. (2013): "15 CTD stations with nephelometric profiles casted in the transform region returned a single hydrothermal plume signal, probably sourced in the MAR segment south of the St. Paul system, while no hydrothermal activity was directly detected inside the transform system"
Notes Relevant to Biology:
Year and How Discovered (if active, visual confirmation is listed first):
2013 plume only
