Ringvent

The position and temperature given in the ver. 3.4 database are for the confirmed Ringvent site from Soule et al. (2018); depth from Alvin Dive 4864 to "Off Axis Ring Vent Area" in 2016; the previous ver. 3.3 database gave a position 27.5600, -111.5500 estimated for the unnamed site from Lizarralde et al. (2011); Lizarralde et al. (2011): "Seafloor photographs from these sites reveal that the high-backscatter features are associated with seafloor biological communities similar to those found at warm-seep areas"; "Temperature anomalies, high methane concentrations and 3He enrichements at the surveyed sites are all consistent with thermogenic methane production driven by heat from magmatic intrusions"; note that unnamed site from Lizarralde et al. (2011) may ultimately be determined to be a hydrothermal seep or cold seep; note that these locations are distinct from Pinkie's Vent, a gas vent at 1582 m depth which is more likely a cold seep at 27 35.5'N, 111 28.5'W on an "eroded transform-parallel fault scarp" (Paull et al. 2007) and ‘Vasconcelos’ site (27 35.5770'N; 111 28.9840'W) cold seep reported by Vigneron et al. (2013)
