Notes on Vent Field Description: 
lat/lon from Global Volcanism Program volcano.si.edu #0607-03; McConachy et al. (2001) AGU Abstract: "Gas bubbling, subsurface sonic activity, and venting of hydrothermal fluids with temperatures around 50ºC are known to occur on the summit at around 10 m depth, and ferruginous oxide deposits several mm thick are common", "Banua Wuhu is a parasitic feature on the north-western side of adjacent Mahenetang Island,"; McConachy et al. (2004): "Banua Wuhu, is an occasionally emergent site of known volcanic and shallow hydrothermal activity", "Gas bubbling, subsurface sonic activity, and venting of hydrothermal fluids with temperatures around 50°C are known to occur on the summit at around 10 m depth,"
Notes Relevant to Biology: 
note: the hydrothermal vents are considered a "natural disturbance" to the coral reefs in this area (Tomascik et al. 1997)
Year and How Discovered (if active, visual confirmation is listed first): 
1996 or earlier, likely by SCUBA
