    Foraminifera and changing pattern of monsoon rainfall 

    Nigam, R. (Current Science Association, Bangalore, India, 1993)
    The palaeomonsoonal history can be reconstructed utilizing climatically sensitive properties of marine microorganisms; foraminifera. The results show a major boundary at 3500 years B.P. and periods of rather low precipitation ...

    Sediment traps as a new tool for estimation of longevity of planktonic foraminifera 

    Nigam, R. (NCAOR, Goa, 2005)
    Sediment trap technique provides time series data of sinking particles (faunal and sediment) from surface to bottom of the sea. Besides many other applications, data can also be used to estimate life span of planktonic ...

    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 ...

    Proloculus size variation in Recent benthic foraminifera: Implications for paleoclimatic studies 

    Nigam, R.; Rao, A.S. (Elsevier, 1987)
    Ratios of dimorphic (microspheric/megalospheric) forms of Foraminifera are affected by temperature and hence are useful in paleoclimatic studies. In some cases, however, it is not possible to distinguish between the dimorphic ...

    A glimpse of the Quaternary monsoon history from India and adjoining seas 

    Saraswat, R.; Nigam, R.; Correge, T. (Elsevier, 2014)
    The evolution of the monsoon is briefly summarized taking into account previous studies conducted on both terrestrial and marine records recovered from the Indian subcontinent and the adjoining seas. While the initiation ...

    Effect of river discharge on the morphology of benthic foraminiferal test 

    Nigam, R.; Khare, N. (Geological Society of India, 1994)
    Twenty one surface sediment samples collected from the inner shelf region off Karwar at 22-52 m water depth range have been studied for foraminiferal content. Based on the external test morphology the entire foraminiferal ...

    Deglaciation in the tropical Indian Ocean driven by interplay between the regional monsoon and global teleconnections 

    Saraswat, R.; Lea, D.W.; Nigam, R.; Mackensen, A.; Naik, Dinesh K. (Elsevier, 2013)
    High resolution climate records of the ice age terminations from monsoon-dominated regions reveal the interplay of regional and global driving forces. Speleothem records from Chinese caves indicate that glacial terminations ...
