Notes on Vent Field Description: 
on the eastern portion of the Galápagos Rift; 2011 cruise blog, accessed 24 April 2015, "Given the extent of living and dead clams around the periphery, this may be one of the largest vent fields found yet on the Galapagos Rift (spanning 130m by 40m)."; Baker et al. (2011): "entire GALREX survey detected ~20 discrete ORP anomalies... Because ORP anomalies are very short lived, and thus do not advect far from their seafloor source, at least ~20 distinct vent "fields" must be active"; WHOI YouTube video, accessed 24 April 2015,
Notes Relevant to Biology: 
2011 cruise blog, accessed 24 April 2015, microbial mats, alvinocarid shrimp, anemones, bathymodiolin mussels, brachyuran crabs, Calyptogena clams, dandelion siphonophores, limpets, Riftia tubeworms; additional biological observations in Shank et al. (2011)
Year and How Discovered (if active, visual confirmation is listed first):
