Chemical Oceanography of the Arabian sea. Part - V. Hydrochemical Characteristics off the Central West Coast of India
(CSIR-NISCAIR, 1980)Data from Arabian Sea cruises 46 (December 1978) and 59 (October 1979) of R V Gaveshani have been used to calculate rates of denitrification at intermediate depths (72-1200 m). About 34% of the available nitrate-nitrogen ... -
Distribution of Urea in the Waters of the West Coast of India
(CSIR-NISCAIR, 1980)Urea concentrations at the surface are high both in coastal and offshore waters in the region north of 15 degrees N (0.3-7.76 mu g at N/litre) and low in the region south of this latitude (0-1.5 mu g at N/litre). Vertical ... -
Nitrogenous nutrients and primary production in a tropical oceanic environment
(Rosenstiel School of Marine and Atmospheric Science of the University of Miami, 1986)Measurements of the concentrations of nitrogenous nutrients and primary production were made at 10 stations along 8 degrees N and 10 degrees N in the tropical oceanic Lakshadweep waters Inorganic nitrogen (NO3, NO2 and ... -
Seasonal changes in Carrageenan and other Biochemical Constituents of Hypnea Musciformis
(CSIR-NISCAIR, 1980)Carrageenan content was maximum in winter. Near inverse relationship was observed between the total carbohydrate and carrageenan. Protein levels were highest when the nitrogenous nutrients were high -
Studies on photosynthetic bacteria isolated from an estuarine beach of Goa
(CSIR-NISCAIR, 1977)A bacterial strain capable of fixing CO2 was isolated from an estuarine beach of Goa, India. The strain grew in sea water containing a piece of boiled egg under anaerobic condition and in the presence of subdued sunlight ...
