The discovery of a hydrothermal helium-3 plume north of the Indian Triple Junction, on the Central Indian Ridge at 19 deg 29 min S is reported. Water column delta (He-3) anomalies show a spike of 33.8 percent at 2460 meter depth, i.e., the highest delta He-3 anomaly recorded so far in the Indian oce...
