Biogeochemistry of the surficial sediments of the western and eastern continental shelves of India
(Coastal Education and Reserch Foundation, 2008)Even though continental margins cover only about 7-9 % of the world ocean area, they are important sites for organic carbon accumulation and hence play a major role in biogeochemical carbon cycling. Surface sediments from ... -
Antibacterial activity of synthesized 2,4,5-trisubstituted imidazole derivatives
(Blackwell Munksgaard, 2008)Some novel chemically synthesized 2,4,5-trisubstituted imidazoles from aryl aldehydes and 1,2-diketones or a-hydroxyketone were screened against eight different human pathogenic bacteria and fungi. Seven compounds were ... -
Temporal variation of diatom benthic propagules in a monsoon-influenced tropical estuary
(Elsevier, 2008)Temporal variations in the diatom benthic propagule (DBP) community and their role in the phytoplankton community in a monsoon-affected tropical estuary, Zuari estuary, Goa (India) are presented. The DBP from the sediments ... -
Laccase treatment of recycled blue dyed paper: Physical properties and fiber charge
(Society for Industrial Microbiology, 2008)Recycled blue colored paper was treated with laccase under various combinations of physical and chemical parameters including enzyme concentration, temperature, oxygen, and reaction time. Laccase treatment of recycled dyed ... -
Sources of hydrocarbons in sediments of the Mandovi estuary and the Marmugoa harbour, west coast of India
(Elsevier, 2008)Surface sediments were collected from various locations of the Mandovi estuary and the Marmugoa harbour, Goa, India. Sediments were analysed for organic carbon (OC), total lipids, n-alkanes concentration and composition. ... -
Evaluation of impairment of DNA integrity in marine gastropods (Cronia contracta) as a biomarker of genotoxic contaminants in coastal water around Goa, west coast of India
(Elsevier, 2008)The measurement of the impairment of DNA in marine gastropod (Cronia contracta) provides an insight into the genotoxic effects of contaminants on marine organisms along the Goa coast. The impact of genotoxic contaminants ... -
Elemental oxides analysis of the medieval period glazed ware from Gogha, Gulf of Khambhat, Gujarat, India
(Current Science Association, 2008)During an inter-tidal zone exploration in the Gulf of Khambhat region, a large number of glazed and nonglazed sherds were recovered along with stone anchors dating back to the late medieval period. Four representative ... -
Formation of algal bloom in the northern Arabian Sea deep waters during January-March: A study using pooled in situ and satellite data
(Taylor & Francis, 2008)The formation of winter bloom (January-March) was studied in deep waters of the northeastern Arabian Sea (NAS) during 2003 and 2004. Six ship cruises were undertaken at different phases of the bloom to examine its formation. ... -
Hyperspectral radiometric observation of the northeast Arabians Sea during April 2006
(The Indian Society of Remote Sensing, 2008)Parameters were retrieved from the hyperspectral radiometer like upwelling and downwelling radiance (Lu and Ed) upwelling and downwelling attenuation (K-Lu and K-Ed) for 9 stations in the northeast Arabian Sea between 16-26 ... -
Indobis and its relevance to the Gulf of Mannar Biosphere reserve
(National Biodiversity Authority, 2008)The Gulf of Mannar (GoM) which has been given the status of a Biosphere Reserve in 1989 under the Man and Biosphere Reserve Programme of UNESCO. It was declared as the first marine protected area in South and South east ... -
Sulfur cycle
(Elsevier, 2008)Microbes, especially bacteria, play an important role in oxidative and reductive cycle of sulfur. The oxidative part of the cycle is mediated by photosynthetic bacteria in the presence of light energy and chemosynthetic ... -
How vulnerable is Indian coast to oil spills? Impact of MV Ocean Seraya oil spill
(Current Science Association, 2008)On 30 May 2006, a bulk carrier, MV Ocean Seraya ran aground along the Karwar coast spilling 650 tonnes of oil. Due to the rough SW monsoon, the spill spread to some beaches in south Goa. The aim of this communication is ... -
Impact of tropical cyclone on biogeochemistry of the central Arabian Sea
(American Geophysical Union, 2008)Remotely sensed data are combined with shipboard measurements to investigate biogeochemical changes caused by a moderate tropical cyclone in the central Arabian Sea in December 1998. The sea surface temperature decreased ... -
Water-column geochemical anomalies associated with the remnants of a mega plume: A case study after CR-2003 hydrothermal event in Carlsberg Ridge, NW Indian Ocean
(Current Science Association, 2008)Recently, an unusually large hydrothermal event (CR- 2003) was reported over the slow-spreading Carlsberg Ridge between 05 degrees 41 minutes N, 61 degrees 30 minutes E and 06 degrees 20 minutes N, 60 degrees 33 minutes ... -
Seasonal variations in the fouling diatom community structure from a monsoon influenced tropical estuary
(Taylor & Francis, 2008)Seasonal variations in the fouling diatom community from a monsoon influenced tropical estuary were investigated. The community composition did not differ significantly between stainless steel and polystyrene substrata due ... -
A cold pool south of Indo-Sri Lanka channel and its intrus on into the southeastern Arabian Sea during winter
(Elsevier, 2008)During winter, south of the Indo-Sri Lanka Channel (ISLC), the observed sea-surface temperature (SST) distribution shows a distinct mini-cold pool (MCP) with relatively cooler waters (SST is less than 28 degrees C). All ... -
Morphological changes at Vellar estuary, India - Impact of the December 2004 tsunami
(Elsevier, 2008)Coastal subsystems formed by interaction of various processes, impacted by natural hazards like tsunami and storms, pose irreversible morphological changes. Vellar estuary, located on the southeast coast of India, with ... -
Hydrography and biogeochemistry of the north western Bay of Bengal and the north eastern Arabian Sea during winter monsoon
