Notes on Vent Field Description:
submarine volcano in the Azores on the Terceira Rift; reported in 2007 as MPA in OSPAR Network "sole representative of a shallow water hydrothermal vent seamount in the Eastern North Atlantic"; some evidence of hydrothermal activity to 400-m depth (not visually confirmed as of 2009)
Notes Relevant to Biology:
bacterial mats; Cardigos et al. (2005): "As with other shallow water hydrothermal vents, the species found closest to the vents on the D. João de Castro seamount are a subset of temperature- and/or sulphide-tolerant local species with no endemic vent species present."
Year and How Discovered (if active, visual confirmation is listed first):
