Notes on Vent Field Description: 
Willaumez Rise, western spreading rifts, Manus Basin; Solwara 11 Project of Nautilus Minerals; Nautilus Minerals press release: "Chimney fields are largely inactive except one where hot water was observed." (; example where academic scientists did not find vents, but commercial group eventually did (first examined 1992 Japanese - only found inactive; French MANAUTE cruise 2000 with Nautile - only found inactive); note: this is close to the location reported by Auzende et al. (2000) and listed by S. Petersen as "Mata na Kul, Vat na Ingiet, Mata na Taru"; Massoth et al. (2008) AGU Abstract: "During June 2008 we conducted a systematic reconnaissance for hydrothermal venting along 1540 km of back-arc features located throughout the Manus back-arc basin. Using real-time plume mapping protocols to discern anomalies in light scattering, temperature, and oxidation-reduction potential, we detected ~45 venting sites, ~34 of which are believed new. Subsequent seafloor reconnaissance by ROV has located massive sulfides coincident to several plumes."
Notes Relevant to Biology: 
Year and How Discovered (if active, visual confirmation is listed first): 
2008 commercial ROV; 2000 submersible Nautile did not confirm activity
