Notes on Vent Field Description:
Bach et al. (2002): "Dredge 36, which recovered basalt pillow lavas from an axial ridge at the western end of the segment, showed a strong above-bottom NTU anomaly and a corresponding increase in . This setting is analogous to axial volcanic ridges that support hydrothermal venting on other slow-spreading ridges"

Year and How Discovered (if active, visual confirmation is listed first):
2000-2001 plume and dredge only
