Seasonal variations in the sediment biogenic properties of a tropical mangrove environment, southwest coast of India
(Springer, 2010)Temporal and spatial changes in the sediment properties of a mangrove ecosystem (Cochin, southwest coast India) are presented. The region was freshwater dominated during monsoon (June-September) and seawater dominated ... -
Long-range transport of dust aerosols over the Arabian Sea and Indian region – A case study using satellite data and ground-based measurements
(Elsevier, 2010)The present study addresses an intense dust storm event over the Persian Gulf and the Arabian Sea (AS) region and its transport over the Indian subcontinent using multi-satellite observations and ground-based measurements. ... -
Environmental controls on the seasonal carbon dioxide fluxes in the northeastern Indian Ocean
(NISCAIR, CSIR, 2010)Total carbon dioxide (TCO sub(2)) and computations of partial pressure of carbon dioxide (pCO sub(2)) had been examined in Northerneastern region of Indian Ocean. It exhibit seasonal and spatial variability. North-south ... -
Skeletonema (Bacillariophyceae) in Indian waters: A reappraisal
(NISCAIR, CSIR, 2010)The planktonic diatom genus Skeletonema is common in Indian coastal waters. Recent taxonomic studies have uncovered high diversity in this genus, and it is expected that several species occur also in the highly diverse ... -
Studies on the reproductive biology of Indian Sand Whiting Sillago sihama (Forsskal)
(NISCAIR, CSIR, 2010)Sillago sihama have a prolonged breeding season from June to December, with spawning activity peaked during the period of September to November. Length at first maturity stage was found to vary between 155-164 mm (total ... -
Antifouling sesquiterpene from the Indian soft coral, Sinularia kavarattiensis Alderslade and Prita
(NISCAIR, CSIR, 2010)A sesquiterpene, (1'E,5'E)-2-(2',6'-dimethylocta-1',5',7'-trienyl)-4-furoic acid [1], was isolated for the first time from the soft coral Sinularia kavarattiensis Alderslade & Prita collected from Gulf of Mannar (Tamil ... -
Distribution of mesopelagic micronekton in the Arabian Sea during the winter monsoon
(NISCAIR, CSIR, 2010)Response of micronekton to oxygen minimum zones in the Arabian Sea (AS) during winter monsoon period was investigated using data of 52 trawls deployed during four winter cruises between 1998 and 2000. Twenty-nine species, ... -
Isolation, optimization and characterization of selected Cyanophycean members
(NISCAIR, CSIR, 2010)Ten spp. of Cyanobacteria (non-heterocytous) were isolated from various marine habitats. Three bioactive potential forms, were observed for their optimization of growth, subjecting them to various concentrations of NaCl, ... -
Naphthalene induced activities on growth, respiratory metabolism and biochemical composition in juveniles of Metapenaeus affinis (H.Milne Edward, 1837)
(NISCAIR, CSIR, 2010)Toxicity of naphthalene was carried out on Metapenaeus affinis (H. Milne Edward, 1837) to investigate its effects on growth, metabolic index and biochemical constituents. Growth rate in terms of weight gain was 32.13% in ... -
Benthic polychaetes as good indicators of anthropogenic impact
(NISCAIR, CSIR, 2010)Seven stations were sampled within the Mormugao harbour area for benthos and environmental variables from September 2003 to July 2004. A total of 71 polychaete taxa were identified from the area. Polychaete abundance, ... -
Antibacterial phenolics from the mangrove Lumnitzera racemosa
(NISCAIR, CSIR, 2010)Antimicrobial activity of the methanolic extract and fractions of Lumnitzera racemosa was evaluated against fungi, virus and pathogenic bacteria. Crude methanolic extract and n-butanol fraction were ineffective against ... -

(NISCAIR, CSIR, 2010)Status of fishery potential of three coastal wetlands, Salcete Taluka viz. Betul Assolna Velim wetland, Loutolim Raia Ambora wetland and Curtorim Macazana wetland in relation to prevailing environmental parameters viz. ... -
Deciphering the modern calcification depth of Globigerina bulloides in the southwestern Indian Ocean from its oxygen isotopic composition
(Cushman Foundation for Foraminiferal Research, 2010)The water depth at which the planktic foraminiferal species Globigerina bulloides calcifies its shell has been deciphered based on the oxygen isotopic composition of its shells in surface sediment samples collected from ... -
Gas hydrate occurrence in the Krishna-Godavari offshore basin off the east coast of India
(Touch Briefings, 2010)India is blessed with adequate reserves of coal and hydro resource whereas the conventional hydrocarbon (oil and gas) reserves so far estimated are inadequate to meet the growing demand of this country. Latest estimates ... -
Inhibitory effect of Indian sponge extracts on bacterial strains and larval settlement of the barnacle, Balanus Amphitrite
(Elsevier, 2010)The total ban imposed on TBT based antifouling paints, since 2008, has triggered the search for Natural Product Antifoulants (NPAs) as a promising alternative for the development of environmentally benign coatings. In view ... -
Nitrogen uptake in the northeastern Arabian Sea during winter cooling
(Hindawi Publishing Corporation, 2010)The uptake of dissolved inorganic nitrogen by phytoplankton is an important aspect of the nitrogen cycle of oceans. Nitrate (NO sub(3) sup(-) and ammonium (NH sub(4) sup(+) uptake rates in the northeastern Arabian Sea using ... -
