Notes on Vent Field Description:
(http://oceanexplorer.noaa.gov/explorations/05galapagos/welcome.html); this field is at the western periphery of the hotspot influence on GSC; Haymon et al. (2008): "The vent field resides on a small, pillowed AVR constructed on the floor of a 3 km-wide axial graben, and is located <1 km west of a larger cone complex"; Anderson et al. (2006): "The Medea survey imaged ... active high-temperature vent fields along the ridge at 94º 04.5'W (Navidad Site), ..."
Notes Relevant to Biology:
Riftia tubeworms, crabs
Year and How Discovered (if active, visual confirmation is listed first):
