Notes on Vent Field Description:
Herzig & Plueger (1988): "Hydrocast and sediment anomalies occur in the northern and southern propagator of the overlapping spreading center in area EX/FX. These anomalies probably originate from more than one low-temperature vent site. A distinct CH4, TDM and 3He anomaly, altered basalts, and increase in potential temperature were found just north of the southern topographic high in area EX/FX"
