Postglacial Indian Ocean
Glacial to Holocene fluctuations in hydrography and productivity along the southwestern continental margin of India
Oxygen isotope and sedimentological records of a sediment core from the southwestern continental margin of India are used to reconstruct the fluctuations in sea surface hydrography and productivity during the last deglaciation. ...
Quaternary radiolarian faunal changes in the tropical Indian Ocean: Inferences to paleomonsoonal oscillation of the 10 degrees S hydrographic front
(Current Science Association, Bangalore, 1997)
The northern Indian Ocean is characterized by three distinct surface water masses, i.e. (1) highly saline (greater than 34.5 ppt) Arabian Sea, (2) low saline (less than 34.5 ppt) Bay of Bengal and (3) a moderate salinity ...
Monsoon related changes in sea surface productivity and water column denitrification in the Eastern Arabian Sea during the last glacial cycle
Sea surface salinity reconstruction for the Holocene and the Last Glacial Maximum (LGM) suggests that the LGM-Eastern Arabian Sea was more saline (by approx.5 psu) than the Holocene due to weakened freshwater flux to the ...
Living coccolithophores during the northeast monsoon from the Equatorial Indian Ocean: Implications on hydrography
Water samples collected at five stations along 931E section (1 degrees N-4 degrees S) during the northeast monsoon (12-15 February 2000) at five depths (surface, 50, 100, 150 and 200 m) in the eastern equatorial Indian ...
A 27,000 year record of Red Sea outflow: Implication for timing of post-glacial monsoon intensification
(American Geophysical Union, 1996)
The history of the Red Sea Outflow (RSO) over the past 27,000 years from an AMS sup(14) C-dated high-resolution Delta sup(13) C record of benthic foraminifera from the inner Gulf of Aden assuming the dominance of circulation ...
Clay minerals as palaeomonsoon proxies: Evaluation and relevance to the late Quaternary records from SE Arabian Sea
(NCAOR, Goa, 2005)
Palaeoclimatic studies are largely dependent on the quality of records and a prudent use of environmental proxy indicators. In this study, the factors affecting the detrital clay minerals in marine environment and their ...
Significance of correspondence between river discharge and proloculus size of benthic foraminifera in paleomonsoonal studies
Variations in the mean proloculus size (MPS) of the benthic foraminiferal species Rotalidium annectens were studied in a core collected off Karwar (20 m water depth), on the west coast of India. Comparison of downcore ...
Past 100 Ky surface salinity-gradient response in the eastern Arabian Sea to the summer monsoon variation recorded by delta super(18)O of G. sacculifer
Northward flowing coastal currents along the western margin of India during winter-spring advect low-salinity Bay of Bengal water in to the Eastern Arabian Sea producing a distinct low-salinity tongue, the strength of which ...
Indian summer monsoon variability during the Holocene as recorded in sediments of the Arabian Sea: Timing and implications
Indian monsoon precipitation fluctuated significantly during the Holocene and a reliable reconstruction of the timing of the events and their implications is of great benefit to our understanding of the effect and response ...
