A first look at factors affecting aragonite compensation depth in the eastern Arabian Sea
Singh, D.P.; Saraswat, R.; Naik, Dinesh K.; Nigam, R. (Elsevier, 2017)Water column measurements suggest shoaling of aragonite saturation depths (ASD) throughout the world oceans, due to increase in greenhouse gas concentration. Past records of aragonite saturation state under different ... -
Assessing the effect of calcein incorporation on physiological processes of benthic foraminifera
Kurtarkar, S.R.; Saraswat, R.; Nigam, R.; Banerjee, B.; Mallick R.; Naik, Dinesh K.; Singh, D.P. (Elsevier, 2015)Rosalina sp. was incubated in seawater spiked with calcein (5 mg/l to 20 mg/l calcein), a dye proposed as efficient marker to tag newly formed calcite, to understand its effect on benthic foraminifera. The experiment was ... -
Deglaciation in the tropical Indian Ocean driven by interplay between the regional monsoon and global teleconnections
Saraswat, R.; Lea, D.W.; Nigam, R.; Mackensen, A.; Naik, Dinesh K. (Elsevier, 2013)High resolution climate records of the ice age terminations from monsoon-dominated regions reveal the interplay of regional and global driving forces. Speleothem records from Chinese caves indicate that glacial terminations ... -
Does Glacial-Interglacial Transition Affect Sediment Accumulation in Monsoon-Dominated Regions?
Singh, D.P.; Saraswat, R.; Naik, Dinesh K. (Wiley, 2017)The spatio?temporal changes in sedimentation rate along the continental margin of the monsoon?dominated eastern Arabian Sea during the last 24 kyr have been estimated from a compilation of 58 radiocarbon dated cores, in ... -
Hydrographic changes in the Agulhas Recirculation Region during the late Quaternary.
Naik, Dinesh K.; Saraswat, R.; Khare, N.; Pandey, A.C.; Nigam, R. (European Geosciences Union, 2014)The strength of Southern Hemisphere westerlies, as well as the positions of the subtropical front (STF), Agulhas Current (AC) and Agulhas Return Current (ARC) control the hydrography of the southwestern Indian Ocean. ... -
Large freshwater-influx-induced salinity gradient and diagenetic changes in the northern Indian Ocean dominate the stable oxygen isotopic variation in Globigerinoides ruber
Saraswat, R.; Suokhrie, T.; Naik, Dinesh K.; Singh, D.P.; Saalim, S.M.; Salman, M.; Kumar, Gavendra; Bhadra, S.R.; Mohtadi, M.; Kurtarkar, S.R.; Maurya, A.S. (Copernicus Publications, Gottingen, Germany, 2023)The application of stable oxygen isotopic ratio of surface-dwelling planktic foraminifera Globigerinoides ruber (white variety; ?18Oruber) to reconstruct past hydrological changes requires a precise understanding of the ... -
Last glacial-interglacial productivity and associated changes in the eastern Arabian Sea
Naik, Dinesh K.; Lea, D.W.; Kurtarkar, S.R.; Mackensen, A. (Elsevier, 2017)We reconstruct paleo-productivity and bottom water oxygenation changes during the past 32ka, from the southeastern Arabian Sea, using absolute abundance of planktic foraminifera, relative abundance of Globigerina bulloides, ... -
Timing, cause and consequences of mid-Holocene climate transition in the Arabian Sea
Saraswat, R.; Naik, Dinesh K.; Nigam, R.; Gaur, A.S. (Elsevier, 2016)We reconstruct centennial scale quantitative changes in surface seawater temperature (SST), evaporation-precipitation (from Mg/Ca and delta18O of surface dwelling planktic foraminifera), productivity (from relative abundance ...
