Geochemistry of sediments
(Oxford and IBH, New Delhi, 2001)
Considering the potential of elemental data in marine sediments as diagnostic tools of various geological and oceanographic processes, sediment geochemical data from the Indian Ocean region has been reviewed in this article. ...
Pyloniid stratigraphy - A new tool to date tropical radiolarian ooze from the central tropical Indian Ocean
Pyloniid stratigraphy, a faunal abundance-variation stratigraphic tool, similar to Cycladophora davisiana stratigraphy employed at high latitudes, is found to work well for tropical radiolarian ooze. The relationship between ...
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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
