North Atlantic climatic changes reflected in the Late Quaternary foraminiferal abundance record of the Andaman Sea, north-eastern Indian Ocean
(Elsevier, 2016)Here, we present planktonic foraminiferal, benthic foraminiferal and other proxy profiles from well-dated sediment cores in the Andaman Sea showing changes in climate and oceanography at Dansgaard-Oeschger (D/O) and Heinrich ... -
Summer monsoon onset-induced changes of autotrophic pico- and nanoplankton in the largest monsoonal estuary along the west coast of India
(Springer, 2016)This study presents the response of autotrophic pico- and nanoplankton to southwest monsoon-associated hydrographical transformations in the Cochin backwaters (CBW), the largest monsoonal estuary along the west coast of ... -
Improving modeling of tides on the continental shelf off the west coast of India
(Coastal Education and Research Foundation, 2016)Global tidal solutions are sometimes inaccurate in coastal regions. This is particularly true in some regions of the northern Indian Ocean, which are characterized by wide continental shelves and large tidal ranges. We ... -
The impact of dredging on residence time in the Amba estuary, west coast of India
(Springer, 2016)In this study, residence time (RT) and flushing characteristics of the Amba estuary were estimated using a 2D depth-averaged model driven by hydrodynamics resulting from the bathymetry changes due to dredging carried out ... -
Distribution and nature of sedimentary organic matter in a tropical estuary: An indicator of human intervention on environment
(Elsevier, 2016)Sediment texture controls the spatial distribution of sedimentary organic matter (SOM) in the Vembanad Lake. Influences of marine derived organic matter (OM) on SOM decreased inner-wards in the northern part of the lake. ... -
Observed internal tides and near-inertial waves on the continental shelf and slope off Jaigarh, central west coast of India
(Elsevier, 2016)The characteristics of internal tides (ITs) and near-inertial waves (NIWs) on the continental shelf and slope off Jaigarh (17degreeN), central west coast of India were studied. Eight-month (March–October) long Acoustic ... -
Mercury-induced genotoxicity in marine diatom (Chaetoceros tenuissimus)
(Springer, 2016)In this paper, we present an evaluation of genotoxic responses in marine diatom, Chaetoceros tenuissimus, isolated from Kandla Creek (lat 23.03° N, long 70.22° E), Gujarat, India, in terms of impairment of DNA integrity ... -
A note on chemical composition and origin of ferromanganese oxide coated and uncoated pumice samples from central Indian Ocean basin
(Geological Society of India, 2016)Pumice are explosive volcanic product, occur as uncoated or coated with ferromanganese (Fe-Mn) oxide and resides in association with ferromanganese nodules on the seabed in Central Indian Ocean Basin (CIOB). The older Fe-Mn ... -
Kahalalide F analogues from the mucous secretion of Indian sacoglossan mollusc Elysia ornata
(Elsevier, 2016)Bioassay-guided fractionation of the CHCl<sub>3</sub>/MeOH extract of Elysia ornata mucus showing antifungal activity led us to isolate kahalalide F(KF) along with two unprecedented related peptides. The structures of ... -
Mesozooplankton production, grazing and respiration in the Bay of Bengal: Implications for net heterotrophy
(Elsevier, 2016)Mesozooplankton samples were collected from the mixed layer along a central (along 88°E) and a western transect in the Bay of Bengal during four seasons covered between 2001 and 2006 in order to investigate spatio-temporal ... -
The zebrafish galectins Drgal1-L2 and Drgal3-L1 bind in vitro to the infectious hematopoietic necrosis virus (IHNV) glycoprotein and reduce viral adhesion to fish epithelial cells
(Elsevier, 2016)The infectious hematopoietic necrosis virus (IHNV; Rhabdoviridae, Novirhabdovirus) infects teleost fish, such as salmon and trout, and is responsible for significant losses in the aquaculture industry and in wild fish ... -
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 ... -
