Dinoflagellate cyst distribution in recent sediments along the south-east coast of India
(Elsevier, 2013)The spatial variation in the dinoflagellate cyst assemblage from the south-east coast of India is presented along with a comparison of the cyst abundance from other regions of the world Samples from 8 stations revealed the ... -
Chemical characterization of meltwater from East Rathong glacier vis-a-vis Western Himalayan glaciers
(Springer, 2015)Ice and meltwater samples from Rathong glacier and its pro-glacial stream Rathong chu, were collected during late winter season. Samples were analyzed to study the chemical composition , weathering, and geochemical processes ... -
Particle swarm optimization based support vector machine for damage level prediction of non-reshaped berm breakwater
(Elsevier, 2015)The damage analysis of coastal structure is very much essential for better and safe design of the structure. In the past, several researchers have carried out physical model studies on non-reshaped berm breakwaters, but ... -
Trace metal concentration in some marine algae of the Maharashtra coast (India)
(1991)74 marine algal species representing Chlorophyta, Phaeophyta and Rhodophyta from ten different stations along the Maharashtra Coast were analysed for the concentration of Mn, Fe, Co, Ni, Cu, Zn and Pb Concentration varies ... -
Coastal erosion assessment along the southern Tamilnadu coast, India
(Cafet-Innova Technical Society, 2012)Coastal zone is a very multi-faceted, energetic and fragile environment because of the influence of both terrestrial and marine ecosystems. Majority of the world�s coastlines are experiencing a wide range of anthropogenic ... -
Blooms of phytoplankton along the west coast of India associated with nutrient enrichment and the response of zooplankton
(Amsterdam: Elsevier, 1992)Incidents of blooms of phytoplankton, discolourations of coastal estuarine waters and swarms of zooplankton are regular features along the west coast of India These are generally concomitant with changes in the chemical ... -
Stigmasterol from Eichhornia crassipes (water hyacinth) : Isolation, characterization and X-ray structure
(Asian Publication Corporation, 2015)Chemical investigation of Eichhornia crassipes (water hyacinth) collected from the back waters of Kochin, southern India lead to isolation of an oxygenated sterol, stigmasterol (1). The molecular formula of 1 was determined ... -
Xylanolytic enzyme systems in Arthrobacter sp MTCC 5214 and Lactobacillus sp.
(Springer, 2015)The production of extracellular xylanolytic enzymes such as xylanase, alfa-L-arabinofuranosidase (alfa-l-AFase), and acetyl xylan esterase (Axe) by marine Arthrobacter sp and Lactobacillus sp was investigated using different ... -
Submarine groundwater discharge and nutrient addition to the coastal zone of the Godavari estuary
(Elsevier, 2015)Submarine groundwater discharge (SGD) represents a significant pathway of materials between land and sea, especially as it supplies nutrients, carbon and trace metals to coastal waters. To estimate SGD fluxes to the Godavari ... -
Environmental drivers of temporal variability in DMS (P) in the surfwater of a tropical intertidal beach
(Discovery Publication, 2014)Tropical estuaries are potential contributors of dimethylsulfide (DMS), a climatically relevant volatile sulfur compound and its precursor dimethylsulphoniopropionate (DMSP) In order to understand the distribution of DMS ... -
Observed changes in ocean acidity and carbon dioxide exchange in the coastal Bay of Bengal - a link to air pollution
(The International Meteorological Institute in Stockholm, 2015)Variations in surface water hydrographic properties and dissolved inorganic carbon (DIC) were evaluated in the coastal Bay of Bengal using observations carried out during March–April 1991 and 2011, including 8 yr monthly ... -
Distribution and sources of aliphatic hydrocarbons and fatty acids in surface sediments of a tropical estuary south west coast of India (Cochin estuary)
(Springer, 2015)Surface sediments samples from the Cochin estuary were measured for elemental, stable isotopic and molecular biomarkers (aliphatic hydrocarbons and fatty acids) to study the sources and distribution of sedimentary organic ... -
Depositional record of trace metals and degree of contamination in core sediments from the Mandovi estuarine mangrove ecosystem, west coast of India
(Elsevier, 2015)The concentrations of seven trace metals (Fe, Mn, Cu, Cr, Co, Pb and Zn) in three sediment cores were analysed to assess the depositional trends of metals and their contamination level in the Mandovi estuary, west coast ... -
Vitellibacter nionensis sp. nov., isolated from shallow water hydrothermal vent of Espalamaca, Azores.
(International Union of Microbiological Societies, 2015)A novel, Gram-negative, non-motile, rod-shaped yellow pigmented bacterium, designated VBW088T was isolated from shallow water hydrothermal vent of Espalamaca, Azores. Phylogenetic analysis based on 16S rRNA gene sequences ... -
Diurnal variability of Synechococcus abundance in Sagami Bay, Japan
(Springer, 2015)Synechococcus, the most dominant picophytoplankton in coastal regions, exhibits diurnal variations in the open ocean. The aim of this study was to assess its short-term population dynamics and cell cycle phases through DNA ... -
Coastal sea level response to the tropical cyclonic forcing in the northern Indian Ocean
(European Geophysical Union, 2015)The study examines the observed storm-generated sea level variation due to deep depression (event 1: E1) in the Arabian Sea from 26 November to 1 December 2011 and a cyclonic storm "THANE" (event 2: E2) over the Bay of ... -
Inter-annual variations in wave spectral characteristics at a location off the central west coast of India
(European Geophysical Union, 2015)The inter-annual variations in wave spectrum are examined based on the wave data measured at 9 m water depth off the central west coast of India from 2009 to 2012 using a wave rider buoy. The temporal variation of the ... -
Dust-induced episodic phytoplankton blooms in the Arabian Sea during winter monsoon
(American Geophysical Union, 2014)Phytoplankton blooms mediated by the oceanic supply of nutrients is a well-understood phenomenon in the Arabian Sea (AS), while the role of dust deposition in enhancing phytoplankton is less explored. In this paper, we ... -
