A first look at past sea surface temperatures in the equatorial Indian Ocean from Mg/Ca in foraminifera
Saraswat, R.; Nigam, R.; Weldeab, S.; Mackensen, A.; Naidu, P.D. (AGU, 2005)Sea surface temperature (SST) for the central equatorial Indian Ocean, has been reconstructed over the last approx. 137 kyr, from Mg/Ca of the planktonic foraminiferal species Globigerinoides ruber. According to our record ... -
A tropical warm pool in the Indian Ocean and its influence on ENSO over the past 137, 000 yrs BP
Saraswat, R.; Nigam, R.; Weldeab, S.; Mackensen, A. (Indian Academy of Sciences, 2007)The tropical sea surface temperature (SST) is one of the important factors that regulates the amount and duration of rainfall in the tropical region, the world’s most densely populated region. The tropical oceanic warm ... -
Linkage between seasonal insolation gradient in the tropical northern hemisphere and the sea surface salinity of the equatorial Indian Ocean during the last glacial period
Saraswat, R.; Nigam, R.; Mackensen, A.; Weldeab, S. (Geological Society of China, 2012)Paired stable oxygen isotope and Mg/Ca analyses in calcite tests of the mixed-layer-dwelling planktic foraminifer Globigerinoides ruber has been used to reconstruct equatorial Indian Ocean delta sup(18)O of seawater (delta ...
