Molecular diversity of fungi from marine oxygen-deficient environments (ODEs)
(Springer, 2012)
Molecular diversity surveys of marine fungi have demonstrated that the species richness known to date is just the tip of the iceberg and that there is a large exent of unknown fungal diversity in marine habitats. Reports ...
Aerosol optical thickness and spatial variability along coastal and offshore waters of the eastern Arabian Sea
(Oxford, 2011)
Data from the ocean-colour monitor (OCM) on board the Indian Remote Sensing Satellite P4 were used to analyse the spatial and temporal distribution of aerosol optical thickness (AOT) over the coastal and offshore waters ...
Quantitative distribution of meiobenthos in the Gulf of Martaban, Myanmar Coast, north-east Andaman Sea
(CSIR-NISCAIR, 2014)
Quantitative distribution of meiofauna in the depth range 20 to 1000 m of the Gulf of Martaban, Andaman Sea was studied from 46 stations during a synaptic survey carried out in April-May 2002 of ORV Sagar Kanya Cruise SK175 ...
Stochastic formalism-based seafloor feature discrimination using multifractality of time-dependent acoustic backscatter
(European Geosciences Union, 2014)
Dual-frequency echo-envelope data acquired using the normal-incidence single-beam echosounder system (SBES) have been examined to study its scale invariant properties. The scaling and multifractality of the SBES echo ...
Phylogeny and genetic variation within population of Tachypleus gigas (M�ller, 1785)
(Current Science Association, IAS, 2017)
Isolated population of Indian horseshoe crabs, Tachy-pleus gigas plays an important role in the ecology of several marine organisms, and is being scrutinized for its abundance and morphology by many researchers. However, ...
Oxygen isotopic composition of relict olivine grains in cosmic spherules: Links to chondrules from carbonaceous chondrites
(Elsevier, 2015)
Most olivine relict grains in cosmic spherules selected for the present study are pristine and have not been disturbed during their atmospheric entry, thereby preserving their chemical, mineralogical and isotopic compositions. ...
A Cenozoic record of the equatorial Pacific carbonate compensation depth
(Nature Publishing Group, 2012)
Atmospheric carbon dioxide concentrations and climate are regulated on geological timescales by the balance between carbon input from volcanic and metamorphic outgassing and its removal by weathering feedbacks; these ...
Speciation of Co, Ni and Cu in the coastal and estuarine sediments: Some fundamental characteristics
(Elsevier, 2012)
Kinetic and sequential extraction methods were used to investigate chemical speciation and distribution of Co, Ni, and Cu in the estuarine and coastal sediments collected from the central east coast of India. The kinetic ...
Antioxidant responses in gills and digestive gland of oyster Crassostrea madrasensis (Preston) under lead exposure
(Elsevier, 2017)
Crassostrea are ecologically and economically important bivalves and provide a good livelihood for coastal regions of many countries, including India. This study aims at evaluating the response of the antioxidant defense ...
Nature of the Ambient Noise, Site Response, and Orientation of Ocean?Bottom Seismometers (OBSs): Scientific Results of a Passive Seismic Experiment in the Andaman Sea
(Seismological Society of America, 2018)
We analyze the nature of the ambient noise and site response for ocean?bottom seismometers (OBSs) deployed in the Andaman region. The probabilistic power spectral densities of the OBSs show that the noise level in the ...
