Notes on Vent Field Description: 
position based on mid points of the ROV transect on 6th July 2015, depth is based on that position in Global Multi-Resolution Topography database; Discovery of a large hot vent site in the Gulf of California:; Exploring Guaymas Basin in the Gulf of California:; Soule et al. (2018): "The 400 m long ridge is made up of four mounds, each of which has a black smoker at its peak. The highly complex vent structures rise 10 m to 30 m from the tops of the mounds and often widen at their tops... Fluid temperatures at the sites reached 331 C as measured by isobaric gas-tight samplers. A similar vent system was found just outside the axial graben, only 1 km north of the black smoker site (H1656). This site also displayed focused venting at 70°C, with vent structures and animal communities (Figure 2d) comparable to those at the Ringvent site.";
Notes Relevant to Biology: 
Soule et al. (2018): "This site (H1656) hosted isolated R. pachyptila tubeworms that were common at the black smoker site.";
Year and How Discovered (if active, visual confirmation is listed first):
