Notes on Vent Field Description:
Walker et al. (2011): "ORP anomalies (-1 to -22 mv) were measured at several locations, primarily along the walls of the crescent-shaped collapse area (or possible caldera) east of the Eolo summit."; Carey et al. (2012): "we found evidence of hydrothermal venting at a number of sites"
Notes Relevant to Biology:
Carey et al. (2012): "small patches (tens of centimeters across) of bright yellow-orange bacteria colonizing fractures in volcanic rock outcrops. In one locale, we encountered a small group of living tubeworms around a small outcrop of manganese-encrusted rocks"; 2011 ROV Little Hercules: http://www.nautiluslive.org/video/2011/09/15/eolo-volcano-tubeworms-dive-highlights;
Year and How Discovered (if active, visual confirmation is listed first):
1976 Fe crusts only; 2007 plume only; 2011 ROV Hercules but can not confirm based on Carey et al. (2012)
