Characterization of seafloor pockmark seepage of hydrocarbons employing fractal: A case study from the western continental margin of India
(Elsevier, 2012)A quantitative technique is applied to describe the seafloor seepages based on the multi-beam backscatter and bathymetric investigations to characterize the pockmark morphology. The variable seafloor backscatter strength ... -
A new spectrofluorometric method for the determination of total arsenic in sediments and its application to kinetic speciation
(Taylor & Francis, 2012)A simple and sensitive spectrofluorometric method has been developed for the determination of arsenic (As) using rhodamine-B as a fluorescent agent. This method is based on the reaction of As(III) with potassium iodate ... -
Genetic algorithm based support vector machine regression in predicting wave transmission of horizontally interlaced multi-layer moored floating pipe breakwater
(Elsevier, 2012)Planning and design of coastal protection works like floating pipe breakwater require information about the performance characteristics of the structure in reducing the wave energy. Several researchers have carried out ... -
Geodynamics of the Amirante Ridge and Trench Complex, Western Indian Ocean
(Taylor & Francis, 2012)The formation and evolution of the approx. 600 km long arcuate Amirante Ridge and Trench Complex (ARTC) is a significant geomorphic– structural feature in the Western Indian Ocean (WIO). The WIO contains evidence of at ... -
Marine archaeological investigations along the Tamil Nadu coast and their implications for understanding cultural expansion to southeast Asian countrie
(Institute of Southeast Asian Studies, 2011)The marine archaeological exploration off Poompuhar and Mahabalipuram brought to light several underwater remains and the traditions mentioning the submergence of these towns have been partially confirmed. -
Hypoxia and Nutrient Reduction in the Coastal Zone: Advice for Prevention, Remediation and Research.
(Global Environment Facility, 2011)Coastal hypoxia is a complex problem and, although research has made great strides in understanding its causes and remedies, more knowledge is needed to fill critical gaps that impede action. -
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
