Notes on Vent Field Description:
ARGO-RISE (1988): "Three active hydrothermal vents were observed in this Unit I terrane", "The observed vents appear to be of the low temperature, Galapagos type, with hot water emanating between lobes of lava. However, the zone of venting at 10 44.6' N covered an area of about 15000 m2, the largest single area of hydrothermal activity found during this investigation."; also observed low temperature, diffuse vents and biology on Alvin Dive 3937 in 2003
Notes Relevant to Biology:
clams, mussels, serpulids
Year and How Discovered (if active, visual confirmation is listed first):
1985 Argo video tow with temperature
