Notes on Vent Field Description:
Plumeria = first active black smoker found on Galapagos Spreading Center (http://oceanexplorer.noaa.gov/explorations/05galapagos/welcome.html); Iguanas (= cluster of 6, 12-14m high chimneys); Haymon et al. (2008): "The largest hydrothermal vent field discovered and imaged with Medea during the GalAPAGoS Expedition is the Iguanas-Pinguinos Field, which is located close to the center of hot spot influence ... A total of 21 active smokers distributed in five clusters were imaged with Medea"; located within the Galapagos Marine Reserve (UNESCO Natural World Heritage Site)
Notes Relevant to Biology:
fauna sparse
Year and How Discovered (if active, visual confirmation is listed first):
2005 towed video Medea
