The tropical sea surface temperature (SST) is one of the important factors that regulates the amount and duration of rainfall in the tropical region, the world’s most densely populated region. The...
Linshy, V.N., Rana, S.S., Kurtarkar, S., Saraswat, R., Nigam, R.
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....
Nigam, R., Mazumder, A., Henriques, P.J., Saraswat, R.
In order to study the response of benthic foraminifera, especially the rectilinear bi- and tri-serial benthic foraminifera (RBF) to oxygen-depleted conditions from the Arabian Sea off central west...
Preface to: Marine micropaleontological studies from the northern Indian Ocean (2007)
Indian Ocean is unique, being land-locked towards the northern margin, and experiences, highest reported oceanic productivity. It is also the locale for the most severe oxygen depleted waters in the...
Nigam, R., Saraswat, R., Kurtarkar, S.R.
Culture experiment has been carried out to observe the response of Pararotalia nipponica (Asano) to different salinities and its salinity tolerance limits. The specimens of P. nipponica kept in 33‰...

Temporal variation in abundance and mean proloculus diameter of the benthic foraminiferal species Epistominella exigua has been reconstructed over the last approx. 50,000 yr BP, from a core collected...
Saraswat, R., Nigam, R., Weldeab, S., Mackensen, A., Naidu, P.D.
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....

Nigam, R., Mazumder, A., Saraswat, R.
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...
Foraminifers as indicators of marine pollution: A culture experiment with Rosalina leei (2004)
Saraswat, R., Kurtarkar, S.R., Mazumder, A., Nigam, R.
In order to develop a viable foraminiferal proxy for heavy metal pollutants, juvenile specimens of Rosalina leei were subjected to different mercury concentrations (0 -180 ng/l). Initially...
Saraswat, R., Mazumder, A., Kurtarkar, S.R., Nigam, R., Ganguly, A.
Despite the extensive use of foraminiferal proxies for paleoclimatic reconstructions, the question how and why morphologic variations of foraminifera are regulated by climatic changes remains a...
Life spans of planktonic foraminifers: New sight through sediment traps (2003)
Nigam, R., Saraswat, R., Mazumder, A.
Determinig the life spans of planktonic foraminifera is vital in view of their increasing use for palaeoclimtic studies. Till date all the estimates about life span of planktonic foraminifers are...
