Notes on Vent Field Description:
Mn crusts on fresh basalt; from Wikipedia: "Owen Transform Fault is used to denote the short section between the end of the Aden-Sheba ridge and the Carlsberg Ridge"; this position is southern part of Owen f.z. near Carlsberg Ridge; note: Sheba Ridge is eastern portion of Aden Ridge; Rona et al. (2005): "Further CR hydrothermal evidence includes relict sulfide chimneys at 58E"
