Notes on Vent Field Description:
during ROV Jason II dive 218 in 2006 a site was observed 8-km NE of PACMANUS, site called "NE Pual"; cruise report: "Another vent field in its waning stages was also discovered ~8 km northeast of PACMANUS on the Northeast Pual Ridge."; lat, lon, depth from Jason Virtual Van; Reeves et al. (2011): "Fluids venting at NE Pual were predominantly low temperature/diffuse in nature in 2006 and only a single fluid with a maximum temperature of 35 C was sampled", "numerous inactive sulfide chimneys and lack of higher temperature venting suggests hydrothermal activity in this area is waning"
Notes Relevant to Biology:
Reeves et al. (2011): "presence of extensive biological activity (snails, shrimp, mussel beds and microbial mats)"
Year and How Discovered (if active, visual confirmation is listed first):
2006 ROV Jason II
