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 ... -

(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 ... -

(Cambridge University Press, 1999)Descriptions of two new sepcies Anchialina labatus and Gastrosaccus sarae, are give. A. lobatus is distinguished from the other species of the genus by the presence of a hairy lobe on the first segment of the antennule, ... -
Altimeter-derived flow field over a newly identified coastal ocean boundary in the eastern Arabian Sea
(NIO, Dona Paula, Goa (India), 2000)A hitherto unknown coastal ocean dynamic boundary has been identified from hydrographic and TOPEX/Poseidon (T/P) altimeter data in the eastern Arabian Sea recently (Antony et al., 2000). This boundary, with a width of about ... -
Longshore currents and sediment trnsport along Kannirajapuram Coast, Tamilnadu, India
