Notes on Vent Field Description:
on SAVANES 1991 cruise no shimmering water observed, but local increase in ambient temperature, and large biological community at Station 41 in the Tikopia area on eastern seamount at a depth of 1425 m; Although Maillet et al. (1995) report this location within the New Hebrides backarc troughs, this location is just south of Starfish Seamount and west of the back-arc spreading axis
Notes Relevant to Biology:
corals, sponges, galathaeid crabs, shrimp
Year and How Discovered (if active, visual confirmation is listed first):
