    Foraminiferal assemblages and their use as indicators of sediments movement: a study in the shelf region off Navapur, India 

    Nigam, R. (Elsevier, 1986)
    Factor analysis of 60 species of foraminifera from 13 stations off Navapur, reveals three major assemblages - Ammonia annectens, Ammonia papillosus-Asterorotalia dentata and Ammobaculites persicus assemblages. These ...

    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 ...

    Geoscientific investigations on the Indian coast: Their application to interpret the paleoclimates and future sea level changes with special reference to greenhouse effect 

    Nigam, R.; Hashimi, N.H.; Pathak, M.C. (1988)
    Objectives of this paper are: (1) To delineate the paleo sea level fluctuations and erosional environmental changes along the Indian Coast and their relationship with the changing coastline and human settlements in the ...

    Fluctuating monsoonal precipitation as revealed by foraminiferal variations in a core from shelf regime off Karwar (India) 

    Nigam, R. (Current Science Association, 1988)
    Variations in the percentage frequency of the foraminifera Cavarotalia annectens in the sediments collected by box core in the shelf region of Karwar, infront of the mouth of the Kalinadi river, India were used to map ...

    Reproductive behaviour of benthic foraminifera: A key to palaeoclimate 

    Nigam, R. (Indian Academy of Sciences, Bangalore, 1988)
    Many benthic foraminiferal species exhibit dimorphism associated with reproduction. The two resultant forms are known as microspheric and megalospheric forms. Culture studies, though limited in number, show that ratios of ...

    Influence of estuaries on shelf foraminiferal species 

    Nigam, R. (CSIR-NISCAIR, 1988)
    Dabhol-bhatkal stretch of the west coast of India is marked by a number of estuaries. Cavarotalia annectens is selected to monitor the influence of these estuaries on the inner shelf foraminiferal fauna. The percentage ...
