Relationship of sediment-biochemistry, bacterial morphology, and activity to geotechnical properties in the central Indian Basin
(Taylor & Francis, 2016)Distribution of biochemical properties, morphological and functional characteristics of bacteria in the extreme sedimentary environment of the Central Indian Basin (CIB) was examined in relation to geotechnical properties ... -
Geochemical characteristics of gold bearing boninites and banded iron formations from Shimoga greenstone belt, India: Implications for gold genesis and hydrothermal processes in diverse tectonic settings
(Elsevier, 2016)This paper is the first documentation of boninites from the Kudrekonda Formation of Shimoga greenstone belt (SGB) in western Dharwar Craton (WDC), India and the occurrence of native gold in the associated quartz veins. We ... -
Major, trace and platinum group element (PGE) geochemistry of Archean Iron Ore Group and Proterozoic Malangtoli metavolcanic rocks of Singhbhum Craton, Eastern India: Inferences on mantle melting and sulphur saturation history
(Elsevier, 2016)The geological and metallogenic history of the Singhbhum Craton of eastern India is marked by several episodes of volcanism, plutonism, sedimentation and mineralization spanning from Paleoarchean to Mesoproterozoic in a ... -
Evaluation of the influence of monsoon climatology on dispersal and sequestration of continental flux over the southeastern Arabian Sea
(Elsevier, 2016)Associated with the coupled land–ocean heating–cooling, seasonal reversal of monsoon winds regulates hydrography, precipitation, upwelling, fluvial influx and a host of biogeochemical processes. We evaluate the role of the ... -
Export of dissolved inorganic nutrients to the northern Indian Ocean from the Indian monsoonal rivers during discharge period
(Elsevier, 2016)Coastal regions are highly productive due to the nutrients largely supplied by rivers. To examine the contribution of dissolved inorganic nutrients (DIN) by Indian rivers to coastal waters, data were collected near the ... -
Setting of cloud albedo in the atmospheric correction procedure to generate the ocean colour data products from OCM-2
(Springer, 2015)Cloud masking is one of the primary and important steps in the atmospheric correction procedure in particular to coastal ocean waters. Cloud masking for ocean colour data processing is based on the assumption that the water ... -
Mid-Pleistocene climate transition drives net mass loss from rapidly uplifting St. Elias mountains, Alaska
(National Academy of Sciences of the United States of America, 2015)Erosion, sediment production, and routing on a tectonically active continental margin reflect both tectonic and climatic processes; partitioning the relative importance of these processes remains controversial. Gulf of ... -
Effect of heavy metals on the carbon and nitrogen ratio in Avicennia marina from polluted and unpolluted regions
(Elsevier, 2015)The accumulation of heavy metals and its impact on the C/N ratio of Avicennia marina of the Patalganga and Amba estuaries were studied. Vadinar was selected as a relatively uncontaminated location for comparison. Cd was ... -
Evaluating changes in the elemental composition of micrometeorites during entry into the earth`s atmosphere
(The American Astronomical Society, 2015)We evaluate the heating of extraterrestrial particles entering the atmosphere using the comprehensive chemical ablation model (CABMOD). This model predicts the ablation rates of individual elements in a particle with a ... -
Role of upper ocean parameters in the genesis, intensification and tracks of cyclones over the Bay of Bengal
(Institute of Marine Engineering, Science & Technology, 2015)It is well known that the frequency of cyclones is about four times higher over the Bay of Bengal when compared with the Arabian Sea. Most of the severe cyclones during pre-monsoon (April and May) and post-monsoon (October ... -
Heavy metals pollution influence the community structure of Cyanobacteria in nutrient rich tropical estuary
(OMICS International, 2015)Anthropogenic inputs influence the community structure and activities of microorganisms, which may impinge the functioning of estuarine and coastal ecosystem. The aim of the present study was to understand the influence ... -
Fluxes of dissolved organic carbon and nitrogen to the northern Indian Ocean from the Indian monsoonal rivers
(American Geophysical Union, 2015)Dissolved organic carbon (DOC) and nitrogen (DON) were measured in 27 major and medium monsoonal estuaries along the Indian coast during southwest monsoon in order to understand the spatial variability in their concentrations ... -
Boninitic metavolcanic rocks and island arc tholeiites from the Older Metamorphic Group (OMG) of Singhbhum Craton, eastern India: Geochemical evidence for Archean subduction processes
(Elsevier, 2015)The metavolcanic rocks of the Paleo-Mesoarchean Older Metamorphic Group (OMG) from Jagannathpur area of the Singhbhum Craton occur as enclaves within the Singhbhum granites (SBG). The primary mineralogical composition of ... -
Asymmetric cell division and its role in cell fate determination in the green alga Tetraselmis indica
(Indian Academy of Sciences, 2015)The prasinophytes (early diverging Chlorophyta), consisting of simple unicellular green algae, occupy a critical position at the base of the green algal tree of life, with some of its representatives viewed as the cell ... -
Use of marine robot`MAYA` for monitoring the Zuari and Mandovi esturine systems
(National Institute of Oceanography, Goa, 2015)Autonomous Surface Vehicles (ASVs) are gaining popularity among oceanographic, meteorological and defense research organizations (Motwani, 2012). The Autonomous Underwater Vehicle, MAYA designed and built at CSIR-NIO (Desa, ... -
Maritime trade contacts of Odisha, east coast of India with the Roman world: An appraisal
(Manohar publishers, New Delhi; India, 2015)The present state of Odisha (previously known as Kalinga, Utkal,Odra and Orissa) lies on the east coast of India, and is known forits maritime contacts with the Roman world since the early histori-cal period, if not earlier. ... -
Environmental isotopes to test hypotheses for fluid mud (mud bank) generation mechanisms along the southwest coast of India
(Elsevier, 2015)Occurrence of fluid mud (mud banks) in the southwest coast of India is an enigma for the scientific community. Over the years, several multi-disciplinary studies were conducted and various hypotheses were postulated on the ... -
Relationship between the lability of sediment-bound Cd and its bioaccumulation in edible oyster.
