Notes on Vent Field Description: 
Ray et al. (2012): "Prominent optical backscatter and thermal anomalies coupled with chemical (e.g., ΔE, 3He, Mn) signatures in seawater demonstrated the existence of hydrothermal sources on off-axis highs on the south wall of the Carlsberg Ridge. Pronounced backscatter anomalies and anomalous DMn concentrations suggest a high temperature hydrothermal source for the plume." "The strength of the ΔE anomaly ensures that the corresponding seafloor source is on the 63°50′E promontory, distinct from the sources found near 63°40′E. "
