Notes on Vent Field Description:
Hydrothermal activity was observed at three localized areas at the Tui Malila vent field, extending approximately 350 m both along the major fault scarp that cuts through the area and near its base; "areas of hydrothermal activity are located close to the dominant fault scarp, and some are associated with volcanic domes"; located within Nautilus Minerals tenement
Notes Relevant to Biology:
snails, mussels
Year and How Discovered (if active, visual confirmation is listed first):
2005 ROV Jason II; 2004 plume only
