Notes on Vent Field Description:
Tamaki et al. (2001): "site in the southern part of the ridge ... with anomalies of LS, CH4, pH and ATP, seems the most promising for finding hydrothermal activity."; "higher strength hydrothermal anomalies identified by both the LSS sensor string and from chemical analyses of CTD 33 samples are coincident with an along-axis topographic low, lying in between adjacent, en echelon segment centers"; "the hydrothermal source we have identified appears to be hosted in tectonically dominated terrain reminiscent of serpentenizing ultramafic outcrops"
