Notes on Vent Field Description:
seamount at northern end of Vate Trough, Coriolis (Southern Backarc) Troughs; Iizasa et al. (1998): "In particular, living hydrothermal biological communities as well as positive temperature anomalies were observed in an area of pillow lava and mound-like Fe Si oxyhydroxide deposits on a submarine caldera (94SO1) in the Vate Trough."; nearby but not within tenement application Nautilus Minerals (SRK report 2011); spreading rate not in Bird (2003), therefore used estimate for South New Hebrides Back-Arc Troughs from Pelletier et al. (1998)
Notes Relevant to Biology:
Iizasa et al. (1998): "Living hydrothermal biological communities of gastropods and galatheid crabs occur near the deposits"
Year and How Discovered (if active, visual confirmation is listed first):
1994 towed camera with temperature
