Notes on Vent Field Description: 
depth approximate using position in GeoMapApp; Baker et al. (2014): "ORP data are only available from the 2010 cruise to segments K and L, where distinct anomalies were detected at 10 separate locations (Figure 6). Segment L hosted most of the ORP anomalies, and would thus be a first choice for seafloor exploration along this part of the SEIR. Of nine ORP profiles along L3, seven had clear plume anomalies. Given a spacing of 7-10 km between each profile, each must have sampled a separate vent field or fields."
Notes Relevant to Biology: 
Year and How Discovered (if active, visual confirmation is listed first): 
2010 plume only
