Quaternary phosphorites off the southeast coast of India
Rao, V.P.; Michard, A.; Naqvi, S.W.A.; Boettcher, M.E.; Krishnaswamy, R.; Thamban, M.; Natarajan, R.; Borole, D.V. (Elsevier, 2002)Detailed petrological, mineralogical, geochemical and radiogenic (U, Sr, Nd) and stable isotope (C, O, S) studies have been carried out on the Quaternary phosphorites of the continental margin off Chennai, southeast coast ... -
Reconstruction of Antarctic climate change using ice core proxy records from the coastal Dronning Maud Land, East Antarctica
Thamban, M.; Laluraj, C.M.; Naik, S.S.; Chaturvedi, A. (Geological Society of India, 2011)Antarctic ice core records have provided unprecedented information on past climatic changes and forcing factors on decadal to millennial timescales. The glaciochemical and stable isotope records of a shallow ice core from ... -
Reconstruction of late Quaternary monsoon oscillations based on clay mineral proxies using sediment cores from the western margin of India
Thamban, M.; Rao, V.P.; Schneider, R.R. (Elsevier, 2002)In order to reconstruct the variations in the intensity of summer monsoon precipitation during the late Quaternary, two sediment cores from the southwestern continental margin of India were studied for their clay mineral ... -
Rock magnetic records of the sediments of the eastern Arabian Sea: Evidence for the late Quaternary climatic change
AnilKumar, K.; Rao, V.P.; Patil, S.K.; Kessarkar, P.M.; Thamban, M. (Elsevier, 2005)Rock-magnetic measurements along with grain size, acid-insoluble residue (AIR), organic carbon (OC), CaCO sub(3) and delta sup(18)O of the planktonic foraminifers of the sediments were determined for 15 gravity cores ... -
Variations in Denitrification and Ventilation Within the Arabian Sea Oxygen Minimum Zone During the Holocene
Kessarkar, P.M.; Naqvi, S.W.A.; Thamban, M.; Fernandes, L.L.; Siebert, C.; Rao, V.P.; Kawahata, H.; Ittekkot, V.; Frank, M. (John Wiley & Sons, 2018)The continental slope of India is exposed to an intense perennial oxygen minimum zone (OMZ) supporting pelagic denitrification. Sediments that are presently in contact with the lower boundary of the denitrification zone ... -
Verdine and glaucony facies from surficial sediments of the eastern continental margin of India
Rao, V.P.; Thamban, M.; Lamboy, M. (Elsevier, 1995)The present paper reports the first mineralogical description of green grains (verdine and glaucony) from sediments of the eastern continental margin of India. Only 24 of the 82 sediment samples studied, at depths between ...
