Biophysical processes in the Indian Ocean
(American Geophysical Union, 2009)Basic physical processes that impact biological activity in the Indian Ocean (IO), namely, near-surface processes (upwelling, entrainment, detrainment, and advection) and subsurface circulations (shallow overturning cells ... -
Net community production in the northern Indian Ocean
(American Geophysical Union, 2009)The monthly/seasonal variability in net community production (NCP) is controlled by the monsoon either through increasing nutrients to the euphotic zone or an increase in river runoff in the northern Indian Ocean. Net ... -
Indian Ocean research: Opportunities and challenges
(American Geophysical Union, 2009)Historically, the Indian Ocean (IO) has received relatively little attention from the oceanographic community and therefore remains substantially undersampled compared to the Atlantic and Pacific oceans. This situation is ... -
Is delta sup(15)N of sedimentary organic matter a good proxy for paleodenitrification in coastal waters of the eastern Arabian Sea?
(American Geophysical Union, 2009)Recently published sedimentary records of delta sup(15)N from several coastal areas affected by both natural and anthropogenically produced shallow hypoxia with the objective of testing this as a proxy for denitrification ... -
Southern Ocean seaweeds: A resource for exploration in food and drugs
(Elsevier, 2009)Benthic macroalga or seaweed, a wonder plant in the sea, has been attracting the human mind since centuries. Countries of south and south East Asia have put in extensive use of this plant for various purposes such as food, ... -
Post depositional memory record of mercury in sediment near effluent disposal site of a chlor-alkali plant in Thane Creek-Mumbai Harbour, India
(Taylor & Francis, 2009)A mercury–cell chlor-alkali plant operating at Airoli (eastern bank of Thane Creek) for 40 years, caused widespread contamination of the surrounding environment. Untreated wastewater from the plant was discharged to Thane ... -
Application of oxidative stress indices in natural populations of Perna viridis as biomarker of environmental pollution
(Elsevier, 2009)Oxidative stress indices were measured in gills and digestive glands of Perna viridis collected from three coastal locations in Goa i.e., Bambolim, Marmugao Harbour and Malim. In addition to lipid peroxidation, the activities ... -
Seasonal dimethylsulfoniopropionate (DMSP) variability in Dona Paula Bay
(Elsevier, 2009)Data on temporal variations of total dimethylsulfoniopropionate (DMSPt) and the environmental factors that influence DMSPt concentrations are important in understanding the biogeochemical cycling of organic sulfur compounds. ... -
Biochemical composition of the marine conditioning film: Implications for bacterial adhesion
(Taylor & Francis, 2009)The conditioning film formed on glass panels was analysed for total carbohydrates (CFCHO), total proteins (CFP) and total uronic acids (CFURA). The influence of these compounds on the adhesion of three marine bacterial ... -
Surface and subsurface geostrophic current variability in the Indian Ocean from altimetry
(Taylor & Francis, 2009)Geostrophic currents were calculated at the surface and subsurface levels in the Indian Ocean using satellite altimetry data from TOPEX/POSEIDON and Jason-1, a geoid obtained from the GRACE mission, and historical hydrographic ... -
Report of epibiont Thecacineta calix (Ciliophora: Suctorea) on deep sea Desmodora (Nematoda) from the Andaman Sea, Indian Ocean
(Marine Biological Association of the United Kingdom, 2010)Suctorian epibionts Thecacineta calix attached on the cuticle of nematodes Desmodora sphaerica and D. pontica are reported here from the deep sea hexactinellid sponge Pheronema sp. from the Andaman Sea (Indian Ocean). The ... -
Threshold effects in semi-enclosed marine systems
(Island Press, 2009)The natural history of the twentieth century documents dramatic changes in many ecological systems, mostly due to the influence of the expansion of human civilization. Semi-enclosed marine systems (SEMSs) are no exception ... -
Limno-tolerant bacteria govern nitrate concentration in Mandovi estuary, India
(Elsevier, 2009)The spatial and temporal abundances of limno-tolerant and halo-tolerant bacteria were investigated in the tide-dominated Mandovi estuary along the west coast of India. These investigations were carried out in relation to ... -
Copper and nickel speciation in mine effluents by combination of two independent techniques
(Elsevier, 2009)To control potentially toxic metals in water resources it is necessary to know metal speciation and changes in the metal speciation that occur after aqueous effluents containing metals are discharged into freshwaters. This ... -
Gametogenic development and spawning of the mud clam, Polymesoda erosa (Solander, 1876) at Chorao Island, Goa
(Taylor & Francis, 2009)The reproductive cycle of Polymesoda erosa was studied over a 12 - month period from July 2004 to July 2005 at Chorao Island, Goa, India. Macroscopic observation revealed that Polymesoda erosa is dioecious and gametogenic ... -
Low-scale foreshore morphodynamic processes in the vicinity of a tropical estuary at Honnavar, central west coast of India
(Coastal Education and Reserch Foundation, 2009)Low-scale foreshore morphodynamic processes in the vicinity of the Sharavati estuary at Honnavar, central west coast of India, are discussed in this paper based on the wave refraction analyses, sediment characteristics, ... -
Provenance signature of pre-cambrian and mesozoic rocks in the nearshore placers of Konkan, central west coast of India
(Taylor & Francis, 2009)Heavy mineral studies of the nearshore placer deposits of the Konkan Coast reveal a dominant assemblage comprised of garnet and kyanite along with other accessory minerals like epidote, olivine and rutile. The heavy mineral ... -
Tandem Wittig-ene reaction approach to kainic acid
