    Need of paleoclimatic reconstructions to understand natural and anthropogenic climatic hazards 

    Nigam, R. (National Institute of Oceanography, India, 2008)
    To formulate the future plans for guarding against the furies of the nature, either due to natural or anthropogenic climatic disasters, understanding of paleoclimatic fluctuations, particularly of the Holocene is of immense ...

    Foramgeographical affinities of the west and east coasts of India: An approach through cluster analysis and comparison of taxonomical, environmental and ecological parameters of Recent foraminiferal thanatotopes 

    Katha, P.K.; Bhalla, S.N.; Nigam, R. (ONGC, India, 2000)
    Q-Mode cluster analysis of one hundred sixty species of Recent foraminifera from twenty nine Recent littoral-thanatotopes from 4000 km long coastal-stretch of India reveals that its west and east coasts belong to two ...

    Does mining pollution affect foraminiferal distribution in Mandovi estuary, Goa, India? 

    Nigam, R.; Nayak, G.N.; Naik, S. (Museum d'histoire naturelle de Geneve, 2002)
    A total of 10 surface sediment samples were collected in the premonsoon season in 1990 from the Mandovi estuary, Goa, India. Study revealed presence of 14 species of foraminifera. The foraminiferal data is of special ...

    Relict faunal testimony for sea-level fluctuations off Myanmar (Burma) 

    Panchang, R.; Nigam, R.; Raviprasad, G.V.; Rajagopalan, G.; Ray, D.K.; Hla, U Ko Yi (The Palaeonlological Society of India, 2008)
    The distribution and ecological significance of the relict benthic foraminiferal assemblage found in the study area off Myanmar is discussed here. Of the 126 surface sediments studied for foraminiferal content, relict ...

    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 ...

    Effects of sudden stress due to heavy metal mercury on benthic foraminifer Rosalina leei: Laboratory culture experiment 

    Nigam, R.; Linshy, V.N.; Kurtarkar, S.R.; Saraswat, R. (Elsevier, 2009)
    Laboratory culture experiments were carried out to understand the response of benthic foraminifer Rosalina leei to gradual as well as sudden addition of heavy metal mercury into the media. When mercury was added suddenly, ...

    Distribution of benthic foraminifera within oxygen minima zone, off central west coast, India 

    Mazumder, A.; Henriques, P.J.; Nigam, R. (Gondwana Geological Society, 2003)
    A total of 128 surface sediment samples (76 grab and 52 core top samples) were analyzed for benthic foraminiferal contents from the region off Goa, India in the eastern Arabian Sea upto a water depth of 3300 m. 195 species ...

    Ecological response of foraminiferal component in the sediments of Kharo Creek, Kachchh (Gujarat), west coast of India 

    Chaturvedi, S.K.; Nigam, R.; Khare, N. (ONGC, India, 2000)
    A total of seven surface sediment samples collected within 4.4 m to 13.9 m water depth (below chart datum) from Kharo Creek were studied for their foraminiferal content. The study reveals forty seven foraminiferal species ...

    Appraisal of laboratory culture experiments on benthic foraminifera to assess/develop paleoceanographic proxies 

    Linshy, V.N.; Rana, S.S.; Kurtarkar, S.; Saraswat, R.; Nigam, R. (NISCAIR, CSIR, 2007)
    The laboratory culture studies, carried out on benthic foraminifera, with the aim to refine paleoceanographic / paleoclimatic or environmental application of benthic foraminifera, have been reviewed. The review includes ...

    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 ...
