Non-conservative controls on distribution of dissolved silicate in Cochin Backwaters
(Asian Fisheries Society, Indian Branch, Mangalore (India), 1999)Cochin backwater system was studied with regard to dissolved silicate (DSi) to understand its seasonal distribution and behaviour during estuarine mixing. Silicate had a linear relationship with salinity during the high ... -
Use of chemicals in aquaculture - issues of concern
(Indian Society for Fishery Professionals, 1999)Majority of aquaculture practices are still based on extensive and semi-intensive farming systems though a trend to intensify operations to enhance yields and improve the efficiency of the production process has emerged ... -
Seasonal and spatial variability in N sub(2)O distribution in the Arabian Sea
(Pergamon, 1999)Extensive measurements of nitrous oxide (N sub(2)O) were made in the central and eastern Arabian Sea during the northeast monsoon (February-March), intermonsoon (April-May) and southwest monsoon (July-August) seasons. The ... -
The effect of pressure and temperature on aluminium hydrolysis: Implications to trace metal scavenging in natural waters
(Council of Scientific and Industrial Research, New Delhi, 1999)Removal of aluminium through precipitation/scavenging in natural waters was evaluated based on its hydrolysis at different temperatures and pressures. In general, pH for the occurrence of cation hydrolysis was lowered with ... -
Baseline studies and evaluation of effects of surface discharge of deep-sea mining - INDEX area
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)Hydrochemical properties of the water column were measured at the Indian Experiment (INDEX) site in the Central Indian Ocean Basin, as a part of baseline studies for the environmental impact assessment of benthic disturbance. ... -
Marine pollution - What are we heading for?
(Indian National Science Academy, New Delhi (India), 1999)Unlike the open ocean, the coastal zone is the most affected and vulnerable to human abuse with several nearshore areas including well-flushed regions and enclosed and semi-enclosed seas getting increasingly polluted. This ... -
Current trends of some organochlorinated pesticides in Yamuna River sediments around Delhi
(Kanuj Envirotech Pvt Ltd., New Delhi, 1999)Organochlorinated pesticides viz. DDTs, HCHs, and Cyclodiene compounds have been detected in the sediment samples of Yamuna River around Delhi, India during the three seasons namely pre-monsoon, monsoon and post-monsoon. ... -
Marine environmental status and coastal zone management issues in India

Effect of mining rejects on the nutrient chemistry of Mandovi Estuary, Goa
(Council of Scientific and Industrial Research, New Delhi, 1999)Nutrient chemistry in Mandovi Estuary, Goa, India during premonsoon in affected by the discharge of mining rejects. Concentrations of nitrate and phosphate, in general, show low levels in this season (nitate 0.3-3.3 mu M, ... -
Nitrogen cycling in the suboxic Arabian Sea: Implications for atmospheric chemistry and climate
(Indian National Science Academy, New Delhi (India), 1999)An acute oxygen deficiency at mid-depths in the Arabian SEa leads to large-scale microbial conversion (denitrification) of the oxidised combined nitrogen species to molecular nitrogen (N sub(2)) at an estimated rate of ... -
Amino acids in the sedimentary humic and fulvic acids
(Council of Scientific and Industrial Research, New Delhi, 1999)Humic and fulvic acids isolated from a few sediment samples from Arabian Sea and Bay of Bengal were analysed for total hydrolysable amino acids concentration and their composition. The amono acids content of fulvic acids ... -
Particulate organic carbon and particulate humic material in the Arabian Sea
(Council of Scientific and Industrial Research, New Delhi, 1999)Variations in particulate organic carbon (POC) and particulate humic material (PHM) were studied in winter (February-March 1995) and intermonsoon (April-May 1994) seasons in the Arabian Sea. Higher levels of POC were found ... -
The oxygen minimum zone in the Arabian Sea during 1995
(Pergamon, 1999)This paper focuses on the characteristics of the oxygen minimum zone (OMZ) as observed in the Arabian Sea over the complete monsoon cycle of 1995. Dissolved oxygen, nitrite, nitrate and density values are used to delineate ... -
Delta sup(14)C, sigma CO sub(2) salinity of the western Indian Ocean deep waters: Spatial and temporal variations
(American Geophysical Union, 1999)Indian Ocean Deep waters (IDW) show an increase in salinity and sigma CO sub(2) between 64 degrees S and 16 plus or minus 4 degrees N by 0.106-0.110 ppt and 82-104 mu M kg sup(-1) respectively with a corresponding decrease ... -
Coastal fisheries research: State of knowledge and needs for Goa
(ICMAM-PD, Chennai (India), 1999)The status of coastal fisheries for the state of Goa (India) is discussed. The research and development capabilities of various institutions; capture fisheries; culture fisheries; and coastal aquaculture in Goa is discussed. ... -
Concentration of metals in shrimps and crabs from Thane-Bassein creek system, Maharashtra
(Council of Scientific and Industrial Research, New Delhi, 1999)Levels of Cu, Zn, Cd, Pb and Ni in shrimps and crabs from Thane-Bassein creek system, Maharashtra, India were evaluated for a period of one year and reported as baseline for future monitoring of this vital ecosystem. The ... -
Experimental studies on the cannibalistic habit of Macrobrachium rosenbergii (de Man)
(Asian Fisheries Society, Indian Branch, Mangalore (India), 1999)Cannibalistic habit of Macrobrachium rosenbergii in intensive cultures was studied in a semi-recycled in a semi-recycled fresh water system under varying environmental conditions. Observations were made on the moulting ... -
Validation of EIA sampling methods - bacterial and biochemical analysis
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)Deep sea sediments from Central Indian Ocean Basin (CIOB) were sampled from 10 degrees .00'-10 degrees .10'S latitude and 75 degrees .55'-76 degrees .05'E longitude for assessing the potential environmental impact of ... -
Insect drift over the northern Arabian Sea in early summer
(Indian Academy of Sciences, Bangalore, India, 1999)Air borne insects, mostly carried by wind currents, were trapped over the northern Arabian Sea (16 degrees to 20 degrees N; 68 degrees to 72 degrees E), in the course of cruise No. 111, ORV Sagar Kanya (March 14 to April ... -
