    Difference in optimum temperature for growth and reproduction in benthic foraminifer Rosalina globularis: Implications for paleoclimatic studies 

    Saraswat, R.; Nigam, R.; Pachkhande, S. (Elsevier, 2011)
    The seawater temperature is an important physical parameter that affects marine benthic community. The effect of seawater temperature however is not consistent throughout various groups of marine benthos. Here, juvenile ...

    Oxygen minimum seafloor ecological (mal) functioning 

    Moodley, L.; Nigam, R.; Ingole, B.S.; PrakashBabu, C.; Panchang, R.; Nanajkar, M.; Sivadas, S.; van Breugel, P.; van Ijzerloo, L.; Rutgers, R.; Heip, C.H.R.; Soetaert, K.; Middelburg, J.J. (Elsevier, 2011)
    Although organic matter (OM) settling on the seafloor is generally rapidly recycled, a key ecological process, large scale burial events manifest itself in the marine sedimentary record as organic carbon (Corg)-rich layers. ...

    Benthic foraminiferal response to changes in mining pattern: a case study from the Zuari estuary, Goa, India 

    Saalim, S.M.; Saraswat, R.; Suokhrie, T.; Bhadra, S.R.; Kurtarkar, S.R.; Nigam, R. (Springer, 2017)
    Being sensitive to environmental changes, foraminifera have been extensively used to monitor pollution level in the marine environment, including the effect of mining in coastal areas. In the Goa state of India, the rejects ...

    Abundance and Ecology of Endemic Asterorotalia trispinosa from the Western Bay of Bengal: Implications for its Application as a Paleomonsoon Proxy 

    Saraswat, R.; Manasa, M.; Suokhrie, T.; Saalim, M.S.; Nigam, R. (Wiley, 2017)
    A total of 97 surface sediment samples were collected from the continental shelf and slope of the western Bay of Bengal to assess the potential application of Asterorotalia trispinosa as a paleomonsoon proxy. The relative ...

    Linkage between seasonal insolation gradient in the tropical northern hemisphere and the sea surface salinity of the equatorial Indian Ocean during the last glacial period 

    Saraswat, R.; Nigam, R.; Mackensen, A.; Weldeab, S. (Geological Society of China, 2012)
    Paired stable oxygen isotope and Mg/Ca analyses in calcite tests of the mixed-layer-dwelling planktic foraminifer Globigerinoides ruber has been used to reconstruct equatorial Indian Ocean delta sup(18)O of seawater (delta ...

    Bathymetric preference of four major genera of rectilinear benthic foraminifera within oxygen minimum zone in Arabian Sea off central west coast of India. 

    Mazumder, A.; Nigam, R. (Indian Academy of Sciences, 2014)
    Fifty two surface sediment samples collected from the region off Goa, central west coast of India from water depths of 15–3300 m were analyzed with special emphasis on foraminiferal content. Rectilinear benthic foraminiferal ...

    An insight into subterranean flow proposition around Alleppey mudbank coastal sector, Kerala, India: Inferences from the subsurface profiles of ground penetrating radar 

    Loveson, V.J.; Dubey, R.; DineshKumar, P.K.; Nigam, R.; Naqvi, S.W.A. (Springer, 2016)
    The mudbank formation along south-western Indian coast has been a scintillating phenomenon during monsoon season, and the source of mud is a debatable issue till now. In the midst of many hypotheses, the subterranean passage ...

    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 ...

    Regeneration and abnormality in benthic foraminifer Rosalina leei: Implications in reconstructing past salinity changes 

    Kurtarkar, S.R.; Nigam, R.; Saraswat, R.; Linshy, V.N. (Universita' degli Studi di Milano, 2011)
    A laboratory culture experiment has been conducted to assess the response of marginal marine benthic foraminifer Rosalina leei to salinity and associated pH changes. Live specimens of Rosalina leei were subjected to a range ...

    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. ...
