Plate-tectonic evolution of the deep ocean basins adjoining the western continental margin of India - A proposed model for the early opening scenario
(Springer, 2015)The available plate-tectonic evolution models suggest that the deep ocean basins adjoining the western continental margin of India have evolved largely due to break-up and dispersal of India, Seychelles and Madagascar ... -
Response of a natural Phytoplankton community from the Qingdao coast (Yellow Sea, China) to variable CO<sub>2</sub> levels over a short-term incubation experiment
(Current Science Association, 2015)Since marine phytoplankton play a vital role in stabilizing earth’s climate by removing significant amount of atmospheric CO<sub>2</sub>, their responses to increasing CO<sub>2</sub> levels are indeed vital to address. The ... -
Identifying the source of tar balls deposited along the beaches of Goa in 2013 and comparing with historical data collected along the west coast of India
(Elsevier, 2015)Deposition of oil residues, also known as tar balls, is a seasonal phenomenon, and it occurs only in the southwest monsoon season along the west coast of India. This has become a serious environmental issue, as Goa is a ... -
Sources, vertical fluxes and accumulation of petroleum hydrocarbons in sediments from the Mandovi Estuary, west coast of India
(University of Tehran, 2015)The Mandovi estuary is highly influenced by mining and tourism related activities in the central west coast of India. Vertical fluxes and accumulation of petroleum hydrocarbons (PHCs) in three sediment cores (D1, C1 and ... -
Detection and monitoring of super sandstorm and its impacts on Arabian Sea-Remote sensing approach
(Elsevier, 2015)The present study addresses an intense sandstorm event over the Persian Gulf and its transport over the Arabian Sea region and the Indian sub-continent using satellite observations and measurements. MODIS data are used to ... -
Re-examination of geophysical data off Northwest India: Implications to the Late Cretaceous plate tectonics between India and Africa.
(Elsevier, 2015)The Gop and Laxmi Basins lying off Northwest India have been assigned ambiguous crustal types and evolution mechanisms. The Chagos-Laccadive Ridge (CLR) complex lying along the southwest coast of India has been attributed ... -
Synechococcus as an indicator of trophic status in the Cochin backwaters, west coast of India
(Elsevier, 2015)Eutrophication is a major problem in coastal water bodies. Information about the trophic status of water bodies will enable proper management of coastal ecosystems. In this regard, biological organisms which are sensitive ... -
Non-destructive foraminiferal paleoclimatic proxies: A brief insight
(Indian National Science Academy, 2015)Non-Destructive Foraminiferal Paleoclimatic Proxies: A Brief Insight The knowledge of past climate can help us to understand imminent climatic changes. Oceans are the vast archives of past climate. Various indirect techniques ... -
Organic matter - A key factor in controlling mercury distribution in estuarine sediment
(Elsevier, 2015)Organic matter (OM) was found to play an important role in controlling mercury (Hg) distribution and speciation in estuarine sediment of the Vembanad Lake. The sedimentary organic carbon (OC) from the northern part of the ... -
Understanding our seas: National Institute of Oceanography, Goa
(Current Science Association, 2015)The present article summarizes the research done at the CSIR–National Institute of Oceanography in 2014 in ocean science, resources and technology. Significant research has been conducted on air–sea interactions and coastal ... -
Genesis of early Cambrian phosphorite of Krol Belt, Lesser Himalaya
(Current Science Association, 2015)Early Cambrian phosphogenesis in the lesser Himalaya is represented by a well-developed sequence of phosphorite, black shale and black chert with interbedded phosphatic dolomite in the Krol Belt. Prevalence of shallow ... -
Phylogenetic analyses and nitrate-reducing activity of fungal cultures isolated from the permanent, oceanic oxygen minimum zone of the Arabian Sea
(NRC Research Press, 2015)Reports on the active role of fungi as denitrifiers in terrestrial ecosystems have stimulated an interest in the study of the role of fungi in oxygen-deficient marine systems. In this study, the culturable diversity of ... -
Hydrothermal Fe cycling and deep ocean organic carbon scavenging: Model-based evidence for significant POC supply to seafloor sediments
(Elsevier, 2015)Submarine hydrothermal venting has recently been identified to have the potential to impact ocean biogeochemistry at the global scale. This is the case because processes active in hydrothermal plumes are so vigorous that ... -
Mineralogy and Sr–Nd isotopes of SPM and sediment from the Mandovi and Zuari estuaries: Influence of weathering and anthropogenic contribution
(Elsevier, 2015)Clay minerals and Sr–Nd isotopes of suspended particulate matter (SPM) and bottom sediment were investigated along transect stations of the Mandovi and Zuari estuaries, western India to determine the provenance and role ... -
Identification of Balanus amphitrite larvae from field zooplankton using species-specific primers
(Marine Biological Association of the United Kingdom, 2015)Identification of marine invertebrate larvae using morphological characters is laborious and complicated by phenotypic plasticity. Balanus amphitrite is a dominant barnacle, important in the context of intertidal ecology ... -
Timing and preservation mechanism of deglacial pteropod spike from the Andaman Sea, northeastern Indian Ocean
(John Wiley, 2015)The aragonite compensation depth (ACD) fluctuated considerably during the last glacial until the Holocene with a dominant pteropod preservation spike during the deglacial period, which is prominently seen in three well-dated ... -
In vitro and in vivo evaluation of the marine sponge skeleton as a bone mimicking biomaterial
(Royal Society of Chemistry, 2015)This investigation was carried out to identify and characterize marine sponges as potential bioscaffolds in bone tissue engineering. The marine sponge (Biemna fortis) samples were collected from the rocky intertidal region ... -
Geochemical partitioning of Cu and Ni in mangrove sediments: Relationships with their bioavailability
(Elsevier, 2015)Sequential extraction study was performed to determine the concentrations of non-residual metal-complexes in the mangrove sediments from the Divar Island, (west coast of India). Accumulation of metal in the mangrove roots ... -
