Notes on Vent Field Description:
submarine volcano 7 km to NE of Santorini; presently categorized with Hellenic Arc, however, Nomikou et al. (2012) suggests this and another listing (VC7) are within the Cyclades back-arc region; http://oceanexplorer.noaa.gov/explorations/06blacksea/welcome.html; http://oceanexplorer.noaa.gov/explorations/06greece/background/geology/geology.html; 25000 m^2 area in NE part of crater floor with chimneys up to 4m high and temperatures up to 220 C (Carey and Sigurdsson 2007); Roman et al. (2012): good description of extent of vent field and bubble plumes.
Notes Relevant to Biology:
from http://www.santonet.gr/santorinivolcano/eruption_newevidence.htm: "The floor of the crater is covered in a layer of red and orange mats of bacteria 2 to 3 inches thick that live on the nutrients in the vent fluids. Bacteria also cover the vent chimneys, and 4- to 5-inch long, hair-like bacterial filaments extend from the chimneys ..."; tunicates
