Notes on Vent Field Description: 
Tao et al. (2017): "The Zouyu-1 (former name: Valentine Valley) and Zouyu-2 (former name: Baily’s Beads) hydrothermal fields are located on the neovolcanic Zouyu ridge on the axis of a symmetrical spreading ridge (on the eastern side of the S14 segment)"; "areal extent of turbidity anomalies around Zouyu-1 and Zouyu-2 in 2009 and 2011 shows that the highest values were concentrated around Zouyu-2"; "The Zouyu-1 hydrothermal field (14.41°W, 13.25°S) was discovered during Chinese 22nd cruise [2011]... A sulfide chimney and a large area of altered basalt nearby were video recorded by underwater camera at a depth of 2315 m. About 4 km south, the Zouyu-2 field (14.41°W, 13.28°S), at a depth of 2288 m, was discovered during Chinese 21st cruise [2009]... Black smokers, polymetallic sulfides, altered basalts, and diffuse venting were video recorded by underwater camera..."; based on Fig. 3 in Tao et al. (2017), Zouyu-1 and Zouyu-2 are presently grouped as 2 vents sites within 1 vent field in this database; Tao et al. (2010): "This venting field lies on an N-S fissure belt in the axial uplift. Black smoker was video recorded while no hydrothermal fauna was found. According to the X-ray diffraction analysis, the sulfides collected by TV-Grab mainly consist of sphalerite and marcasite."; Devey (2014): AUV Abyss dive 135;
Year and How Discovered (if active, visual confirmation is listed first):
