Calcium phosphate saturation in seawater around the Andaman Island
Naik, S.; Reddy, C.V.G. (CSIR-NISCAIR, 1983)Ionic product (IP) of calcium phosphate is calculated at some stations around Andaman Island. The depthwise variations of the ionic product of calcium phosphate seem to follow a normal trend with maximum saturation value ... -
Calcium Phosphate Saturation in the Western Bay of Bengal
Naik, S.; Reddy, C.V.G. (CSIR-NISCAIR, 1980)Temperature, inorganic phosphate concentration and pH seem to be the major factors influencing the degree of saturation of calcium phosphate in sea water. Two water regions can be demarcated in the study area based on the ... -
Chemical oceanography of the Arabian Sea: Part II - Equilibrium of inorganic nitrogen system
Naik, S.; SenGupta, R. (CSIR-NISCAIR, 1975)The concept pE, expressed as a dimensionless quantity to study the redox potential of a system at equilibrium, is applied to study the chemistry of the system NO-<sub>3</sub>-NO-<sub>2</sub>NH+<sub>4</sub> in the northern ... -
Does mining pollution affect foraminiferal distribution in Mandovi estuary, Goa, India?
Nigam, R.; Nayak, G.N.; Naik, S. (Museum d'histoire naturelle de Geneve, 2002)A total of 10 surface sediment samples were collected in the premonsoon season in 1990 from the Mandovi estuary, Goa, India. Study revealed presence of 14 species of foraminifera. The foraminiferal data is of special ... -
