Chemistry of the sea-surface microlayer. 3. Studies on the nutrient chemistry of the northern Arabian Sea
(Oxford and IBH, New Delhi, 1992)Nutrients showed enrichment in the surface microlayer compared to those in sub-surface water and there was a decreasing trend in the enrichment factor from nearshore to offshore in Northern Arabian Sea. The nutrient ... -
Evaluation of toxic trace metals Cd and Pb in Arabian Sea waters
(Oxford and IBH, New Delhi, 1992)An attempt has been made to present a picture of the distribution of toxic trace elements Cd and Pb in the Northern Arabian Sea by applying an improved analytical technique for the detection of dissolved forms of the metals ... -
Minor sterols from the sponge Ircinia ramosa (Killer)
(Oxford and IBH, New Delhi, 1992)Three sterols, isolated from the lipid fraction of the sponge Ircinia ramosa were characterised as cholest-5-en-3 beta-ol-7-one (7-oxo cholesterol, 1), cholest 5-23-dien-b beta ol-7-one (7-oxo demosterol, 2) and 24E-ethyl ... -
Organochlorine pesticide residues in the northern Indian Ocean
(Oxford and IBH, New Delhi, 1992)The coastal waters of India receive about 4.4Km sup(3) of domestic sewage and 0.44 Km sup(3) of industrial wastes, annually. A concerted effort is being made for about a decade now to assess the state of the Indian marine ... -
Corrosion of mild steel, copper and brass in crude oil / seawater mixture
(NISCAIR, New Delhi, 1992)Mild steel, copper and brass coupons were introduced in natural seawater containing varying amount of crude oil. Mild steel showed higher rate of corrosion in seawater containing oil and lower corrosion rate in natural as ... -
On chlorinated hydrocarbons in the Indian Ocean
(Oxford and IBH, New Delhi, 1992)The data available on the distribution of organochlorine compounds such as DDT and its metabolites, aldrin, dieldrin, endrin, isomers of HCH and the PCBs in the sediments, water, zooplankton, fish and seals from the Indian ... -
Distribution of particulate organic matter in Rajapur and Vagothan estuarines (west coast of India)
(NISCAIR, New Delhi, 1992)The distribution of particulate organic carbon (POC), particulate carbohydrates (PCHO) and particulate proteins (PP) in the suspended particulate matter was studied. The POC, PCHO and PP concentrations ranged from 176 to ... -
Inorganic combined nitrogen budget of the Arabian Sea: Some geochemical and climatic implications
(Waseda University, Tokyo, 1992)Estimates of the local sources and sinks of inorganic combined nitrogen in the Arabian Sea suggest a net loss of sup(-)3 x 10 sup(13) gN y sup(-1). This seems to be made up largely by the upward flux facilitatEd. by a high ... -
Bioactivity of marine organisms. 6. Antiviral evaluation of marine algal extracts from the Indian coast
(Walter de Gruyter, Berlin, 1992)Ethanolic extracts of Indian marine algae belonging to the Rhodophyceae, Phaeophyceae and Chlorophyceae were tested for anti-semiliki Forest (SFV), Ranikhet Disease (RDV) and Vaccinia (VV) viruses. In the primary screening ... -
Influence of pollution of boron chlorinity ratio
(Society of Biosciences, Muzaffarnagar, India, 1992)Presence of boron in domestic wastewater has resulted in high B/CI ratio at some locations in the coastal water around Bombay. A widest range (0.215-0.281) of B/CI was observed at a location with high influence of wastewater ... -

Boron chemistry in relation to its variations in eastern Arabian Sea
(NISCAIR, New Delhi, 1992)Boron varied from 3.96 to 5.3 mg.kg-1 in the coastal and from 3 to 4.74 mg.kg-1 in the offshore waters. B/Cl showed a wide variation from 0.202 to 0.269 in the coastal region while significantly low ratios (0.2) to as high ... -

Water masses and property distribution in the EEZ of Mauritius
(Oxford and IBH, New Delhi, 1992)Water masses and their properties have been studied in the Mauritian during September-October, 1987. Surface water is characterizEd. by two water masses: 1) a warm (temp. 27 degrees C) and relatively saline water (salinity ... -
Field culture of American strain of Artemia in India
(NISCAIR, New Delhi, 1992)Pilot scale culture of Artemia was carried out in a 0.22 ha condenser unit of salt pans. Pond was fertilized with inorganic salts. The nauplii of San Francisco Bay, USA strain were inoculated. Within a period of 5 months ... -
Biochemical composition of zooplankton of Bombay High (oil platform) area in the Arabian Sea
(NISCAIR, New Delhi, 1992)Variations in the biochemical constituents and calorific values of zooplankton from an off-shore oil processing platform were estimated. Mean value of biomass was 0.35 ml.m/3 with relatively higher values during post-monsoon ... -
Unusual thickening of collarette in Sagitta bedoti (Chaetognatha) from the polluted environments of Bombay coast
(NISCAIR, New Delhi, 1992)Sangitta bedoti dominated the chaetognath fauna of the nearshore waters of Bombay. S. bedoti from the polluted creek environments developed an unusually bulky collarette which extended from the neck to the seminal vesicles. ... -
Rhopalophthalmus constrictus sp. nov. and Australomysis reubeni sp. nov. (Crustacea-Mysidacea) from south-west Australian waters
