    Orbital frequencies in radiolarian assemblages of the central Indian Ocean: implications on the Indian summer monsoon 

    Gupta, S.M. (Elsevier, 2003)
    Radiolarian distribution in surface sediments and its relationships with overlying surface oceanography provided impetus for down-core faunal variation related to changes in monsoon intensity due to the Earth's orbital ...

    Seafloor and sediment characteristics in INDEX AREA 

    Sharma, R.; Nath, B.N.; Valsangkar, A.B.; Khadge, N.H.; Gupta, S.M.; Parthiban, G. (Metal Mining Agency of Japan, 1997)
    Seafloor surveys and sediment sampling during the INDEX (Indian Deep-Sea Environmental Experiment) studies in the Central Indian Basin, resulted in identification of Test and Reference Areas, as well of establishment of ...

    Evidence for recent hydrothermal activity in the Central Indian Basin 

    Iyer, S.D.; ShyamPrasad, M.; Gupta, S.M.; Charan, S.N. (Pergamon, 1997)
    This study documents the first actual prof of recent intraplate volcanic-hydrothermal activity in the Central Indian Basin (CIB). Twenty-six surface sediments and a spade core (37 cm long) from the CIB were examined for ...

    Evidence of Himalayan erosional event at approx. 0.5 Ma from a sediment core from the equatorial Indian Ocean in the vicinityof ODP Leg 116 sites 

    Nath, B.N.; Gupta, S.M.; Mislankar, P.G.; Rao, B.R.; Parthiban, G.; Roelandts, I.; Patil, S.K. (Elsevier, 2005)
    A sediment core collected from an area _100 miles south of the ODP Leg 116 (distal Bengal Fan) in the equatorial Indian Ocean was investigated for microfossils, mineralogy, mineral chemistry, magnetic susceptibility, grain ...

    Radiolarian zonation and volcanic ash layers in two Quaternary sediment cores from the Central Indian Ocean Basin 

    Gupta, S.M. (Palaeontological Society of India, 1988)
    Radiolarian abundance in two Quaternary sediment cores, collected from the Central Indian Basin, was studied and Nigrini's (1971) and Goll's (1980) zones are recognised. New radiolarian zones Collosphaera orthoconus, ...

    Two layers of Australian impact ejecta in the Indian Ocean 

    ShyamPrasad, M.; Gupta, S.M.; Kodagali, V.N. (Meteoritical Society, 2003)
    Only 2 Australian tektites have been found in the Indian Ocean, and both are associated with surficial sediments. Cores from both locations are collected, where the tektites have been reported. The microtektites in these ...

    Tropical sea surface temperatures and the earth's orbital eccentricity cycles 

    Gupta, S.M.; Fernandes, A.A.; Mohan, R. (American Geophysical Union, 1996)
    The tropical oceanic warm pools are climatologically important regions because their sea surface temperatures (SSTs) are positively related to atmospheric greenhouse effect and the cumulonimbus-cirrus cloud anvil. Such a ...

    210Pb, 230Th, and 10Be in Central Indian Basin seamount sediments: Signatures of degassing and hydrothermal alteration of recent origin 

    Nath, B.N.; Borole, D.V.; Aldahan, A.; Patil, S.K.; Mascarenhas-Pereira, M.B.L.; Possnert, G.; Ericsson, T.; Ramaswamy, V.; Gupta, S.M. (Wiley, 2008)
    Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ...

    Radiolarian abundance and geochemistry of the surface-sediments from the Central Indian Basin: Inferences to Antarctic bottom water current 

    Gupta, S.M.; Jauhari, P. (Current Science Association, 1994)
    The distribution trend of numbers of radiolarian shells/gram dry sediment, biogenic silica, organic carbon, and the carbon/nitrogen ratios in the surface sediments of the Central Indian Basin is similar. Ratios of two ...

    Fe speciation and Fe/Al ratio in the sediments of southeastern Arabian Sea as an indicator of climate change 

    Pattan, J.N.; Parthiban, G.; Gupta, S.M.; Mir, I.A. (Elsevier, 2012)
    Aluminium, titanium and iron are the major lithogeneous contributors to the marine sediment and their abundance varies strikingly with the intensity of monsoonal precipitation. Al and Ti concentrations in a sediment core ...
