Notes on Vent Field Description:
field is 15km long, in steps going down from east to west from 1800 m to 2800 m depth; Tao et al. (2009): "This field extends about 15-km long in parallel to the ridge axis and locates at about 10-km off the ridge axis. Abundant different live and dead faunas were found. Many carbonate material and basalt samples were recovered. This new basalt-hosted carbonate field could represent a new category of ridge hydrothermal system"
