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 ... -
Effect of salinity induced pH/alkalinity changes on benthic foraminifera: A laboratory culture experiment
(Elsevier, 2015)The salinity of coastal waters in the vicinity of seasonally fresh water fed estuaries changes tremendously and reportedly affects the living calcite secreting organisms like foraminifera, as well as their dead remains. ... -
Distribution and dynamics of mangrove forests of South Asia..
(Elsevier, 2015)Mangrove forests in South Asia occur along the tidal sea edge of Bangladesh, India, Pakistan, and Sri Lanka. These forests provide important ecosystem goods and services to the region's dense coastal populations and support ... -
Implications of sea level rise scenarios on land use /land cover classes of the coastal zones of Cochin, India..
(Elsevier, 2015)Physical responses of the coastal zones in the vicinity of Cochin, India due to sea level rise are investigated based on analysis of inundation scenarios. Quantification of potential habitat loss was made by merging the ... -
Atmospheric outflow of nutrients to the Bay of Bengal: Impact of anthropogenic sources..
(Elsevier, 2015)The air–sea deposition of nutrients (N, P and Fe) to the oceanic regions locateddownwind of pollution sources in south and south-east Asia is gaining considerable attention in the present-day scenario of climate change. ... -
Anaerobic nitrification–denitrification mediated by Mn-oxides in meso-tidal sediments: Implications for N2 and N2O production..
(Elsevier, 2015)Field measurements in the Arcachon Bay (southwest France) indicated anaerobic production of NOx via nitrification, which was coupled to the reduction of Mn-oxides. To prove the occurrence of this process, laboratory microcosm ... -
CHEMTAX-derived phytoplankton community structure associated with temperature fronts in the northeastern Arabian Sea..
(Elsevier, 2015)Remotely sensed sea surface temperature (SST) and chlorophyll associated with fronts and filaments are used in India to generate potential fishing zone (PFZ) advisories in the north eastern Arabian Sea (NEAS). However, ... -
The distribution of the chaetognath population and its interaction with environmental characteristics in the Bay of Bengal and the Arabian Sea.
(Taylor and Francis, 2015)The Bay of Bengal (BoB) and the Arabian Sea (AS), the two major ocean basins in the north Indian Ocean, share similarities in geographical and meteorological characteristics but differ in hydrographic characteristics and ... -
Application of hybrid techniques (self-organizing map and fuzzy algorithm) using backscatter data for segmentation and fine-scale roughness characterization of seepage-related seafloor along the western continental margin of India
(IEEE, 2015)In this paper, a seafloor characterization technique to unravel the number of data classes using multibeam echo-sounding backscatter data has been demonstrated. An application of self-organizing maps (SOMs) to backscatter ... -
Variations in the inorganic carbon components in the thermal fronts during winter in the Northeastern Arabian Sea
