Notes on Vent Field Description:

position and depth approximate; Halbach et al. (1995) did not find direct evidence of hydrothermal activity or deposits, but did find temperature anomalies at two locations on "eastern fault bounding of the axial ridge"

Notes Relevant to Biology:

Year and How Discovered (if active, visual confirmation is listed first):

1995 deep tow
