Notes on Vent Field Description:
Tao et al. (2010): "Evidence of sulfide video and hydrothermal anomalies indicated the existence of the 14°S hydrothermal field."; "The 14°S hydrothermal field is located on the [slope] of the volcano, which lies on the inside corner between the ridge axial and transform fault"; InterRidge e-news 2011: "Rainbow Bay North field was found at 14.36°W, 14.03°S at a depth of 1900m, which may extend to 480m×780m. Massive sulfides were collected by a ROV."; check Li et al. (2014) for confirmation; note sites may be renamed to Ruyu-1 and Caifan-1, off-axis segment S15 in Tao et al. (2017);
Year and How Discovered (if active, visual confirmation is listed first):
2009 towed video did not confirm activity
