Notes on Vent Field Description: 
J. Ishibashi (pers. comm.): "we have dove near a overlap spreading section around 13.0N and found some evidence for activity (33 deg C shimmering fluid and Fe-precipitation). Fluid sampling point was recorded as 13_05.924'N, 143_41.321'E, depth 2885m"; this observation of 'Kaiko' hydrothermal area is likely from SHINKAI 6500 Dive 0901, see: "YK05-09 Leg.2 Cruise Report"; proximity to plumes 5 and 6, southern Mariana Trough (Baker et al. 2005); Segment 13.3 N Sites 8 and 9 in Baker et al. (2017), Site 8: 13.137 N, 143.689 E, 2930 m; Site 9: 13.170 N, 143.698 E, 2894 m; both sites are expected to be low temperature (Baker et al. 2017);
Year and How Discovered (if active, visual confirmation is listed first): 
2000 deep-tow camera (later, same year - ROV Kaiko)
