Notes on Vent Field Description:
location and depth approximate, pending data for depth range; Barragan et al. (2001): "hot springs of San Felipe boil at various places along the shoreline. According to Gastil and Bertine (1982), the springs are located on the south side of a ridge of oxide-bearing meta-carbonic rocks. Some of the springs are accessible exclusively during low tide. Gastil and Bertine (1982) describe mostly CO2 gas bubbles. In addition, fishermen have reported the existence of submarine hot springs", "coastal springs of San Felipe and Punta Estrella to the San Miguel Fault", "originated by seawater mixing with local meteoric water. The high salinity of the San Felipe and Punta Estrella springs is explained by leaching of evaporate sediments"
Year and How Discovered (if active, visual confirmation is listed first):
1982 or earlier, likely from shore
