    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. ...

    Distributional pattern of benthic foraminiferal morpho-groups in the shelf region off Mangalore: Environmental implications 

    Khare, N.; Sinha, R.; Rai, A.K.; Nigam, R. (NISCAIR, CSIR, 1995)
    The foraminiferal population in 45 surface sediment samples (20-86 m water depth) off Mangalore, Karnataka, India, was divided into benthic and planktonic assemblages. Within the benthic community based on the external ...

    Effect of salinity induced pH/alkalinity changes on benthic foraminifera: A laboratory culture experiment 

    Saraswat, R.; Kouthanker, M.; Kurtarkar, S.R.; Nigam, R.; Naqvi, S.W.A.; Linshy, V.N. (Elsevier, 2015)
    The salinity of coastal waters in the vicinity of seasonally fresh water fed estuaries changes tremendously and reportedly affects the living calcite secreting organisms like foraminifera, as well as their dead remains. ...

    A first look at past sea surface temperatures in the equatorial Indian Ocean from Mg/Ca in foraminifera 

    Saraswat, R.; Nigam, R.; Weldeab, S.; Mackensen, A.; Naidu, P.D. (AGU, 2005)
    Sea surface temperature (SST) for the central equatorial Indian Ocean, has been reconstructed over the last approx. 137 kyr, from Mg/Ca of the planktonic foraminiferal species Globigerinoides ruber. According to our record ...

    Deterioration of Early Holocene coral reef due to sea level rise along west coast of India: Benthic foraminiferal testimony 

    Mazumder, A.; Nigam, R.; Henriques, P.J. (China University of Geosciences (Beijing), 2012)
    A total of 103 surface sediment samples collected from the water depth range of 15-3300 m along Vijaydurg-Karwar stretch of central west coast of India were analyzed for foraminiferal content. Relict benthic foraminiferal ...

    Growing need to study foraminifera in the laboratory culture experiments: An attempt from the central west coast of India 

    Nigam, R.; Khare, N.; Koli, N.Y. (K.D. Malaviya Institute of Petroleum Exploration, Dehra Dun (India), 1996)
    In recent past much emphasis has been laid on the high resolution reconstruction of the paleoclimatic conditions to help in preparing the futuristic climatic model. Many such efforts have used foraminifera as proxy indicators ...

    A foraminiferal testimony for the reduced adverse effects of mining in Zuari Estuary, Goa 

    Panchang, R.; Nigam, R.; Baig, N.; Nayak, G.N. (Taylor and Francis, 2005)
    This paper demonstrates the potentiality of foraminifera in detecting mining pollution. Goa's Mandovi-Zuari estuarine complex is most vulnerable to deterioration caused by the mining industry. The objective of the present ...

    Experiment to decipher the effect of heavy metal cadmium on coastal benthic foraminifer Pararotalia Nipponica (Asano) 

    Linshy, V.N.; Saraswat, R.; Kurtarkar, S.R.; Nigam, R. (Palaeontological Society of India, 2013)
    The response of benthic foraminifer Pararotalia nipponica to heavy metal cadmium is observed in laboratory experiment. The results indicate that under a given set of conditions, heavy metal cadmium is deleterious to benthic ...

    Mean proloculus size, delta super(13) C and delta super(18) O variations in recent benthic foraminifera from the west coast of India and their climatic implications 

    Nigam, R.; Sarkar, A. (Indian Society of Earth Sciences, Calcutta, 1993)
    The interrelationship between mean proloculus size (MPS), delta super(18) O and delta super(13) C vatiations in benthic foraminiferal species Rotalidium annectens and their relation with temperature (T) and salinity (S) ...
