The ITS-based phylogeny of fungi associated with tarballs
(Elsevier, 2016)Tarballs, the remnants of crude oil which change into semi-solid phase due to various weathering processes in the sea, are rich in hydrocarbons, including toxic and almost non-degradable hydrocarbons. Certain microorganisms ... -
Gravity anomalies over the central Indian ridge between 3 degree S and 11 degree S, Indian Ocean: Segmentation and crustal structure
(Indian Academy of Sciences, 2016)High-resolution shipboard geophysical investigations along the Indian Ocean ridge system are sparse especially over the Carlsberg and Central Indian ridges. In the present study, the shipboard gravity and multibeam bathymetry ... -
Evolution to decay of upwelling and associated biogeochemistry over the southeastern Arabian sea shelf
(AGU Publications, 2016)Observations along 10 shelf transects in 2012 near 10°N in the southeastern Arabian Sea revealed the usual warm oligotrophic conditions during the winter monsoon and upwelling of oxygen-deficient, nutrient-rich cool water ... -
Ablation and chemical alteration of cosmic dust particles during entry into the earth`s atmosphere
(American Astronomical Society, 2016)Most dust-sized cosmic particles undergo ablation and chemical alteration during atmospheric entry, which alters their original properties. A comprehensive understanding of this process is essential in order to decipher ... -
Bioactive alkaloids from marine sponges
(2016)Marine sponges are considered to be a rich source of biologically active secondary metabolites with unique and diverse chemical structures. They constitute nearly one third of the secondary metabolites isolated from marine ... -
Chemical ecology of marine sponges
(Springer, 2016)Sponges successfully inhabit diverse habitats ranging from hard- to soft-bottom communities, tropical to polar latitudes, intertidal to deep-sea environments and fresh- to saltwaters, which are shared by other organisms. ... -
Spatial and temporal variations of wave energy in the nearshore waters of the central west coast of India
(Copernicus Publications, 2016)Assessment of wave power potential at different water depths and time is required for identifying a wave power plant location. This study examines the variation in wave power off the central west coast of India at water ... -
Fungal phylogenetic diversity in estuarine sediments of Gautami Godavari River, Andhra Pradesh, India
(2016)Mangroves are a unique ecosystem that experiences fluctuations in salinity which is influenced by terrestrial and marine environment, tidal waves and wind velocity. The aforesaid factors provide a suitable environment for ... -
Evaluation of antioxidant and cytotoxic properties of Cynobacteria, Limnothrix sp. and Leptolyngbya sp. from Arabian sea
(Faculty of Biotechnology and Food Sciences, 2016)The hexane fractions of the marine cyanobacteria: Leptolyngbya sp. and Limnothrix sp., collected from Arabian Sea were found to display promising antioxidant properties than their ethyl acetate fraction during radical ... -
Deformation of textural characteristics and sedimentology along micro-tidal estuarine beaches
(NISCAIR, 2016)Deformation in the textural characteristics of three selected beaches (Pavinkurve, Kundapura and Padukare) along Karnataka shoreline, west coast of India was examined. Study showed the beaches are significantly composed ... -
A novel DNase like compound that inhibits virus propagation from Asian green mussel, Perna viridis (Linn.)
(NISCAIR, 2016)Viral diseases are not only responsible for health related issues but also exert pressure on the State economy. Tropical and subtropical countries have more prevalence of virus associated pathological conditions such as ... -
Pleurobranchus forskalii (Ruppell & Leuckart, 1828)- A new record for Indian coastal waters
(Society for Science and Nature, 2013)Ophisthobranchs are brightly coloured Marine Molluscs, with high species diversity, wide distribution range, occurring oncoral reefs, seagrass beds, mangroves, sandy, muddy and rocky habitats (Nithyanandan, 2012) There are ... -
Influence of atmospheric dry deposition of inorganic nutrients on phytoplankton biomass in the coastal Bay of Bengal
(Elsevier, 2016)The aerosols from continents contain relatively higher amounts of inorganic nutrients than those of marine origin and can make a notable contribution to the coastal biological productivity. To test this hypothesis, the ... -
Diversity and bioactive potentials of culturable heterotrophic bacteria from the surficial sediments of the Arabian Sea
(Springer, 2016)Marine sediments accommodate plethora of diverse microorganisms with varying ecological functions. In the present study, we isolated bacteria from surficial sediments of south east Arabian Sea (AS) and evaluated their ... -
CSIR - National Institute of Oceanography
(Indian National Science Academy, 2016)This is an institutional report of CSIR-National Institute of Oceanography, India showcasing its growth over last 50 years in Oceanographic research with special focus on Indian Ocean areas. The major research areas include ... -
Biodiversity and biogeography pattern of benthic communities in the coastal basins of India
(Taylor & Francis, 2016)Our understanding of coastal biogeography patterns is presently limited to certain regions and marine groups. Comprehending large-scale patterns and their underlying predictors is critical due to the changing environmental ... -
Relict olivines in micrometeorites: Precursors and interactions in the earth`s atmosphere
(American Astronomical Society, 2016)Antarctica micrometeorites (~1200) and cosmic spherules (~5000) from deep sea sediments are studied using electron microscopy to identify Mg-rich olivine grains in order to determine the nature of the particle precursors. ... -
Middle cretaceous geomagnetic field anomalies in the eastern Indian Ocean and their implication to the tectonic evolution of the Bay of Bengal
(Elsevier, 2016)The Middle Cretaceous period is largely known for its stable normal polarity in the Earth's magnetic field. A few reversals (ISEA, M-3r; M-2r and M-1r) have been postulated during this period but are yet to be accepted in ... -
Pink-line syndrome
(John Wiley & Sons, Inc., 2016)Pink-line syndrome (PLS) was first observed in 1996 affecting the scleractinian coral Porites lutea at Kavaratti of the Lakshadweep islands in the Arabian Sea. The ability of the two fungi isolates and P. valderianum to ... -
