Notes on Vent Field Description:
McConachy et al. (2001): "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"; relatively near this database record, potential new listing for shallow submarine hydrothermal vent field Temboko Lehi Beach associated with Karangetang volcano (https://volcano.si.edu/volcano.cfm?vn=267020) 2.781°N, 125.407°E; another potential new listing for shallow submarine hydrothermal vent field offshore Tobelo although not in Sangihe Arc but rather on Halmahera Arc 1°43′55″N 128°0′28″E
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
