Notes on Vent Field Description:
located in Vate Basin, Coriolis (Southern Backarc) Troughs, New Hebrides backarc spreading center; spreading rate not in Bird (2003), therefore used estimate for South New Hebrides Back-Arc Troughs from Pelletier et al. (1998); active 2001, but note: hydrothermal plume not detected in 2004; McConachy et al. (2005): "Video showed clear and milky fluids emitted through fissures and gaps in fresh glassy, vesicular, lightly sediment covered to uncovered pillow, sheet-flow, and tube-flow basalts with associated iron oxyhydroxides and vent fauna"; Facebook posting for R/V Sonne Cruise SO-229, 22 July 2013: "Absolutely stunning day at Nifonea! Black smokers with temperatures of up to 360 C! Boiling!"
Notes Relevant to Biology:
McConachy et al. (2005): "Extensive hydrothermal fauna and yellow-brown crusts and mounds cover an area of 1 km2," "Vent fauna include galatheid crabs, mussels, tubeworms, spaghetti worms, and scale worms"
Year and How Discovered (if active, visual confirmation is listed first):
2001 towed video; 2013 ROV Kiel 6000 black smokers
