Notes on Vent Field Description:
Kelley et al. (2012): 8m tall extinct structures at base of wall (see http://media.marine-geo.org/video/upflow-zone-western-wall-endeavour-segment-2007). Continuous exposure of upflow zone 200m across, 100m high on wall with massive sulfide, sulfide breccia, well-lithified metalliferous sediments. CTD results indicate weakly venting system immediately to northeast. Along western axial valley wall.; Kelley et al. (2014): "exposed stockwork system south of Mothra"
