Notes on Vent Field Description: 
Hydrothermal fluids are discharged at a temperature of 85 C. Preliminary data on the structures, pH, and seismic activity in the study zone were reported by Núñez-Cornú et al. (2000); not related to active volcanism; "continental margins actively affected by extension tectonic processes" (Canet and Prol-Ledesma 2007)
Notes Relevant to Biology: 
characterized by the presence of algal-mats that cover small mounds (up to 2.5 m in diameter and 0.75 m in height) around the submarine hot springs
Year and How Discovered (if active, visual confirmation is listed first): 
1997 photo/video most likely by SCUBA
