Oxygen isotope and salinity variations in the Indian sector of the Southern Ocean
A combined study of stable oxygen isotopes (δ 18 O) and salinity of surface ocean waters collected from the Southern Indian Ocean during the late austral summer and early fall (25th January to 1st April, 2006) helped to trace atmospheric and oceanic processes: near the equator, a very clear signatur...
