Microbial communities associated with Antarctic snow pack and their biogeochemical implications
(Urban & Fischer, 2016)Snow ecosystems represent a large part of the Earth's biosphere and harbour diverse microbial communities. Despite our increased knowledge of snow microbial communities, the question remains as to their functional potential, ... -
Glutathione S-transferase, catalase, superoxide dismutase, glutathione peroxidase, and lipid peroxidation as a biomarkers of oxidative stress in snails: A review
(University of Modena and Reggio Emilia, 2016)Antioxidant defense plays a crucial role in the response of an organism to pollutants. Several processes stimulate the production of free radicals or deplete the antioxidant defense, which if not regulated properly, may ... -
Tropical cyclone activity over the Southwest Tropical Indian Ocean
(Wiley, 2016)The Southwest Tropical Indian Ocean (SWTIO) is a key region for air-sea interaction. Tropical cyclones (TCs) regularly form over the SWTIO and subsurface ocean variability influences the cyclogenesis of this region. Tropical ... -
Heat content of the Arabian Sea Mini Warm Pool is increasing
(John Wiley & Sons, Ltd, 2016)Sea surface temperature in the Arabian Sea Mini Warm Pool has been suggested to be one of the factors that affects the Indian summer monsoon. In this paper, we analyze the annual ocean heat content (OHC) of this region ... -
Sponge-Associated Bacteria Produce Non-cytotoxic Melanin Which Protects Animal Cells from Photo-Toxicity
(Springer, 2017)Melanin is a photo-protective polymer found in many organisms. Our research shows that the bacteria associated with darkly pigmented sponges (Haliclona pigmentifera, Sigmadocia pumila, Fasciospongia cavernosa, Spongia ... -
Phytochemical studies on marine green algae Boodlea composite of Ukha, west coast of India
(Indian Chemical Society, 2017)Phytochemical investigation of marine green algae Boodlea compositae collected from the Ukha, west coast of India led to the isolation and identification of 22 constituents: -sitosterol, loliolide and 132 -hydroxy-(132 ... -
Improved Bathymetric Dataset and Tidal Model for the Northern Bay of Bengal
(Taylor & Francis, 2016)The Bengal Delta is a highly complex and vulnerable environment where key dynamical features such as tides, storm surges, salinity, and sediment transport strongly depend on the accurate bottom topography representation. ... -
Latitudinal environmental gradients and diel variability influence abundance and community structure of Chaetognatha in Red Sea coral reefs
(Taylor & Francis, 2017)The Red Sea has been recognized as a unique region to study the effects of ecohydrographic gradients at a basin-wide scale. Its gradient of temperature and salinity relates to the Indian Ocean monsoon and associated ... -
Pseudofaults and associated seamounts in the conjugate Arabian and Eastern Somali basins, NW Indian Ocean - New constraints from high-resolution satellite-derived gravity data
(Pergamon, 2016)Marine gravity data derived from satellite altimeters are effective tools in mapping fine-scale tectonic features of the ocean basins such as pseudofaults, fracture zones and seamounts, particularly when the ocean basins ... -
Robust particle filter formulations with application to terrain-aided navigation
(Wiley-Blackwell, 2017)The work described in this paper is motivated by the need to develop efficient and robust estimation filters with application to terrainaided navigation of underwater robotic vehicles. One of the main problems addressed ... -
Tropical explosive volcanic eruptions can trigger El Ni�o by cooling tropical Africa
(Nature Publishing Group, 2017)Stratospheric aerosols from large tropical explosive volcanic eruptions backscatter shortwave radiation and reduce the global mean surface temperature. Observations suggest that they also favour an El Ni�o within 2 years ... -
S- and Sr-isotopic compositions in barite-silica chimney from the Franklin Seamount, Woodlark Basin, Papua New Guinea: constraints on genesis and temporal variability of hydrothermal fluid
(Springer Berlin Heidelberg, 2017)Isotopic ratios of strontium and sulfur in six layers across a horizontal section of a hydrothermal barite-silica chimney from Franklin Seamount of western Woodlark Basin have been investigated. Sr-isotopic ratios in barite ... -
Mossbauer spectroscopy and x-ray diffraction studies of ferromanganese nodules from central Indian ocean basin
(Indian Society of Applied Geochemists, 2017)We report room temperature 57Fe Mossbauer spectroscopic and powder X-ray diffraction studies carried out on Fe-Mn nodules collected from the Central Indian Ocean Basin, to understand the oxidation state of Iron. Mossbauer ... -
Modulation of equatorial Pacific westerly/easterly wind events by the Madden-Julian oscillation and convectively-coupled Rossby waves
(Springer Berlin Heidelberg, 2016)Synoptic wind events in the equatorial Pacific strongly influence the El Niño/Southern Oscillation (ENSO) evolution. This paper characterizes the spatio-temporal distribution of Easterly (EWEs) and Westerly Wind Events ... -
Characteristics of eigen-system for flexural gravity wave problems
(Taylor & Francis, 2017)For a class of boundary value problems associated with flexural gravity waves, characteristics of the eigen-system are analysed which are used to study the convergence of the expansion formulae in both cases of single and ... -
Iridium(III) and Rhodium(III) compounds of dipyridyl-N-alkylimine and dipyridyl-NH-ketimine: Spectral characterization and crystal structure
(Springer India, 2017)Pentamethylcyclopentadienyl iridium(III) and rhodium(III) complexes of formulation [( 5-C 5Me 5)M{(C 5 H 4N) 2 C=NR)}Cl]PF 6 were prepared by the reaction of [MCl 2( 5-C 5Me 5)] 2(M = Ir or Rh) with dipyridyl-N-alkylimine ... -
Glacial-interglacial contrasts revealed by n-alkanes in sediments of the Equatorial Indian Ocean during the last 300,000 years
(Elsevier, 2017)A sediment core aged up to 300 kyr from the Equatorial Indian Ocean (EIO) was examined for its inorganic and organic geochemistry, the objective being to identify coherent markers of glacial-interglacial changes and ... -
Sphingobacterium bovisgrunnientis sp. nov., isolated from yak milk
(Microbiology Society, 2018)A novel Gram-negative, rod shaped, non-motile bacterium, designated strain YK2T, was isolated from yak milk from Leh, India. The strain was positive for oxidase- and catalase-activities and negative for starch hydrolysis, ... -
Ostracod biodiversity from shelf to slope oceanic conditions, off central Bay of Bengal, India
(Elsevier, 2017)Thirty seven surface sediment samples collected through a multi-corer in seven transects of ORV Sagar Kanya, SK 308 Leg-1 from off central Bay of Bengal (shelf to slope environment) were analysed for living and dead ... -
