Notes on Vent Field Description: 
first announcement of black smokers in InterRidge e-news #01/2010 (January 14th, 2010): "The first cruise one year ago... video sled surveys of the East Scotia Ridge (ESR). That cruise obtained the first seafloor observations of vent fields on the ESR; indeed the furthest south black smokers have been seen so far by ~20 degrees of latitude."; first posted image of black smokers on northern end of the East Scotia Ridge:; see Marsh et al. (2015) for vent field description and video of Dog's Head
Notes Relevant to Biology:
