Vent Sites:
Grotta Azzurra (= Grotto Azzura)
Grotta Sulfurea (= Sulphureous grotto)
Notes on Vent Field Description:
tectonic setting categorized as "other" based on description in Stueben et al. (1996): "The chemical data suggest that the proposed thermal fluid contains two components, one derived from seawater (< 90%) and the other from low-salinity groundwater (> 10%). The heat source for the circulating fluids is uncertain, but may involve warm underlying igneous rocks or heating via the geothermal gradient."; note: M. Hannington lists with Aeolian Islands, but it is not part of the Aeolian Arc; not part of Palinuro Volcanic Complex
Notes Relevant to Biology:
for microbes, see Canganella et al. (2005)
Year and How Discovered (if active, visual confirmation is listed first):
1990 or earlier, likely by SCUBA
