Do cold, low salinity waters pass through the Indo-Sri Lanka Channel during winter?
(Taylor & Francis, 2011)During winter, along the east coast of India, the near-surface flow is characterized by the southward-flowing East India Coastal Current (EICC) which bends around Sri Lanka and enters into the south-eastern Arabian Sea ... -
Significance of biofilm proteins in modulating cyprid metamorphosis of Balanus amphitrite (Cirripedia: Thoracica)
(Blackwell Verlag GmbH, 2011)The role of biofilm proteins in modulating cyprid metamorphosis is not well understood. In the present investigation this possibility was explored by disrupting biofilm proteins using commercially available protease. The ... -
Occurrence of red tide caused by Karenia mikimotoi (toxic dinoflagellate) in the Southwest coast of India
(NISCAIR (CSIR), 2011)Intense brownish discoloration was observed in the surface waters of Cochin barmouth on 21st October 2009, which found to extend a few kilometers in the coastal waters. Continuous monitoring was carried out in the region ... -
Aggregation of Euphausia sibogae during summer monsoon along the southwest coast of India
(Hindawi Publishing, 2011)The influence of environmental parameters on the spawning aggregation of Euphausia sibogae was investigated along the southwest coast of India during the peak phase of summer monsoon 2005. The prevailing ecological conditions ... -
Variations of Indian monsoon precipitation during the last 32 kyr reflected in the surface hydrography of the Western Bay of Bengal
(Elsevier, 2011)Hydrography of the Bay of Bengal is highly influenced by the river runoff and rainfall during the southwest monsoon. We have reconstructed delta sup(18)Osw, sea surface salinity and sea surface temperature (SST) changes ... -
Influence of orographically enhanced SW monsoon flux on coastal processes along the SE Arabian Sea
(American Geophysical Union, 2011)The Arabian Sea has an excess evaporation over precipitation regime. The southeast Arabian Sea is, however, anomalous because it has ~2800–4800 mm rainfall during the southwest monsoon (SWM). Despite a high rainfall, the ... -
Atmospheric dry deposition of inorganic and organic nitrogen to the Bay of Bengal: Impact of continental outflow
(Elsevier, 2011)The continental outflow from south and south-east Asia, persisting during January to March, dominates the widespread dispersal of pollutants over tropical Bay of Bengal. With a view to assess the impact of anthropogenic ... -
Carbon dioxide observations at Cape Rama, India for the period 1993–2002: implications for constraining Indian emissions
(Current Science Association, 2011)India has the second largest population, one of fastest growing economies and is ranked third in greenhouse gas emissions by fossil-fuel burning in the world. However, there has been little monitoring of atmospheric CO ... -
Indian estuaries: Dynamics, ecosystems, and threats
(National Academy of Sciences, 2011)Indian estuaries have special features that are derived from occurrence of the wet Indian Summer Monsoon (June-September) and hence have been called monsoonal estuaries. High runoff during the wet season and a 8-month long ... -
Intraseasonal vertical velocity variation caused by the equatorial wave in the central equatorial Indian Ocean
(American Geophysical Union, 2011)Intraseasonal vertical velocity variation in the central equatorial Indian Ocean was investigated using observations from the field experiment "Mirai Indian Ocean Cruise for the Study of the MJO-convection Onset" and from ... -
Quantitative Estimation of Coastal Changes along Selected Locations of Karnataka, India: A GIS and Remote Sensing Approach
(Scientific Research Publishing, 2011)Qualitative and quantitative studies on changes of coastal geomorphology and shoreline of Karnataka, India have been carried out using toposheets of Survey of India and satellite imageries (IRS-P6 and IRS-1D). Changes ... -
Organic carbon in Antarctic snow: spatial trends and possible sources
(American Chemical Society, 2011)Organic carbon records in Antarctic snow are sparse despite the fact that it is of great significance to global carbon dynamics, snow photochemistry, and air–snow exchange processes. Here, surface snow total organic carbon ... -
Synthesis of the naturally occurring prenylated coumarins balsamiferone and cedrelopsin by domino reactions
(ARKAT-USA, Inc, 2011)Regioselective one step synthesis of naturally occurring prenyl coumarin balsamiferone is described using domino Wittig reaction, 3,3-sigmatropic rearrangements and deprenylation, while regioselective synthesis of cedrelopsin ... -
Model-based seafloor characterization employing multi-beam angular backscatter data - A comparative study with dual-frequency single beam
(Acoustical Society of America, 2011)Sediment geoacoustic inversion results are estimated employing a multi-beam (MB) echo-sounding system operable at 95 kHz. To characterize the western continental shelf of India (off Goa) seafloor, MB backscatter signals ... -
High resolution climate reconstructions of recent warming using instrumental and ice core records from coastal Antarctica
(India Meteorological Department, 2011)In-situ observational record of Antarctic surface temperatures is rather sparse. Proxy based ice core studies are thus critical for reconstructing the past climate change on centennial and decadal time scales. The present ... -
Mixed layer processes of the Arabian Sea Warm Pool during spring intermonsoon: a study based on observational and satellite data
(Taylor & Francis, 2011)The relative importance and contribution of various processes in the total heat budget in the mixed layer of the Arabian Sea Warm Pool (ASWP) during spring intermonsoon (March–April 2004) were studied using in situ ... -
An overview of dinoflagellate cysts in recent sediments along the west coast of India
(NISCAIR (CSIR), 2011)Distribution and abundance of dinoflagellate cysts in recent sediments along the west coast of India (26 coastal stations and 3 ports) is presented. A total of 47 different types of cysts and a maximum abundance of 1076 ... -
Phytoplankton species composition, abundance and distribution in Fishing area 58 of Indian Ocean sector of Southern Ocean
(NISCAIR (CSIR), 2011)Phytoplankton species composition, abundance and standing stocks investigations were carried out during the First Indian Antarctic Krill Expedition (FIKEX). Nitrate, phosphate and silicate were available in sufficiently ... -
Pre- and post-monsoonal changes in grain size and heavy minerals in the sediments from Kalbadevi Bay, Ratnagiri, west coast of India
