    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 ...

    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 ...

    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 ...

    Spatial and temporal distribution of foraminifera in sediments off the central west coast of India and use of their test morphologies for the reconstruction of paleomonsoonal precipitation 

    Nigam, R.; Khare, N. (Micropaleontology Press, 1999)
    From the shallow region off the central west coast of India, 21 samples of surface sediments (ranging in depth from 22 to 52 m) along with two sediment cores of 4.80 m and 4.00 m (surface/subsurface) have been analyzed for ...

    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 ...

    Signals of the change in monsoonal precipitation at around 2,000 years BP in a sediment core off central west coast of India 

    Nigam, R.; Khare, N. (Current Science Association, 1994)
    A 4.80 m long shallow water sediment core, collected from the inner shelf (at 22 m water depth) off Karwar near Kali River mouth is studied for foraminiferal tracers of palaeomonsoons. The climatic history of this core ...

    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 ...

    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) ...
