Notes on Vent Field Description:
just NW of 16 40′S Triple Junction on Central Spreading Ridge; LaFoy et al. (1990): "The N15 and N160 ridges converging with the North Fiji Fracture Zone constitute the 16°40′ S Ridge-Ridge-Fracture Zone triple junction."; within area KF-1 with magnetic survey in 2012 (Choi et al. 2013)
Year and How Discovered (if active, visual confirmation is listed first):
1985 plume only; 1991 temperature anomalies but submersible Shinkai 6500 did not confirm activity
