    Ammolagena clavata (Jones and Parker, 1860), an agglutinated benthic foraminiferal species - first report from the Recent sediments, Arabian Sea, Indian Ocean region 

    Nigam, R.; Mazumder, A.; Saraswat, R. (Cushman Foundation for Foraminiferal Research, 2004)
    The rare presence of the agglutinated foraminiferal species Ammolagena clavata is presented for the first time from the Recent sediments of the Indian Ocean region. This species has previously been reported in Recent ...

    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 ...

    Do inverted depositional sequences and allochthonous foraminifers in sediments along the Coast of Kachchh, NW India, indicate palaeostorm and/or tsunami effects? 

    Nigam, R.; Chaturvedi, S.K. (Springer, 2006)
    The study of 134 subsurface sediment samples from three cores collected along the Coast of Kachchh, off Gujarat Province, NW India, shows the presence of 151 foraminifer species. Q-mode cluster analysis on foraminifer data ...

    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 ...

    Cyclicity in the Late Holocene monsoonal changes from the western Bay of Bengal: Foraminiferal approach. 

    Rana, S.S.; Nigam, R. (The Palaeontological Society of India, 2009)
    Benthic foraminiferal characteristics, including abundance of total benthic foraminifera, angular asymmetrical benthic foraminifera, Uvigerina sp. and Bulimina marginata, have been studied in a piston core (exihibiting ...

    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 ...

    Significance of correspondence between river discharge and proloculus size of benthic foraminifera in paleomonsoonal studies 

    Nigam, R.; Khare, N. (Springer, 1995)
    Variations in the mean proloculus size (MPS) of the benthic foraminiferal species Rotalidium annectens were studied in a core collected off Karwar (20 m water depth), on the west coast of India. Comparison of downcore ...

    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 ...
