Authigenic carbonates in the sediments of Goa offshore basin, western continental margin of India
(Current Science Association, 2012)Euhedral crystals (approx. 1 mm) of authigenic carbonates are identified in 5 m long sediment cores collected from the western continental margin of India in water depths between 2665 and 3070 m. Low-Mg calcite and aragonite ... -
Variations in nearshore waves along Karnataka, west coast of India
(Indian Academy of Sciences, 2012)Wind wave spectra were recorded simultaneously at three shallow (water depth 7–9 m) locations (Malpe, Honnavar and Karwar) along the 200 km stretch of the state of Karnataka in 2009 during 27 April–24 May (representing ... -
Phenyltins in Surface Sediments of the Visakhapatnam Harbour, India
(Springer, 2012)Twenty-two surface sediment samples were collected from Visakhapatnam harbour, east coast of India, and analysed for monophenyltin (MPT), diphenyltin (DPT), triphenyltin (TPT), total bacteria, and TPT tolerant bacteria. ... -
Biofilm-associated indole acetic acid producing bacteria and their impact in the proliferation of biofilm mats in solar salterns
(Institute of Molecular Biology, Slovak Academy of Sciences, 2012)Biofilm mats appear in salterns distinctively during the monsoon season when the salinity decreases below 12 percentile salinity units and within a short period cover the entire surface area of the saltern. A study was ... -
Recent developments in the synthesis of five- and six-membered heterocycles using molecular iodine
(WILEY-VCH Verlag GmbH, 2012)Heterocyclic scaffolds represent the key structural subunits of many biologically active compounds. Over the last few years iodine-mediated reactions have been extensively studied due to their low cost and ecofriendliness. ... -
TropFlux: air-sea fluxes for the global tropical oceans-description and evaluation
(Springer-Verlag, 2012)This paper evaluates several timely, daily air-sea heat flux products (NCEP, NCEP2, ERA-Interim and OAFlux/ISCCP) against observations and present the newly developed TropFlux product. This new product uses bias-corrected ... -
समुद्रतल से तलछट के उप-नमूनों को एक साथ निकालने वाला विशेष कोर लाइनर
(National Research Development Corporation, 2012)Describes the device that consists of a portable and reusable special core liner (SPCL). It accomplishes real-time sub-sampling of aqueous sediments. Besides being revolutionary, inexpensive and user-friendly, the SPCL is ... -
First records of three Paraprionospio species (Polychaeta: Spionidae) from Indian waters
(Station Biologique de Roscoff, 2012)new records; geographical distribution; animal morphology; taxonomy; Paraprionospio cordifolia; Paraprionospio cristata; Paraprionospio patiens Abstract :The spionid polychaete Paraprionospio pinnata (Ehlers, 1901) has ... -
Stable isotopes of carbon and nitrogen in suspended matter and sediments from the Godavari estuary
(Springer, 2012)Spatial distribution of the carbon and nitrogen content and their isotopic enrichment in suspended matter and sediments were measured in the Godavari estuary to identify the sources and transformation mechanism of organic ... -
A first look at the dinoflagellate cysts abundance in the Bay of Bengal: implications on Late Quaternary productivity and climate change
(Current Science Association, 2012)Abundance and composition of dinoflagellate cysts in a sediment core (SK218/1) from the Bay of Bengal were examined for the last 23 kyr. Cyst abundance at this site varied from 20 to 153 cysts/g dry wt, which is far less ... -
Application of otolith shape analysis in identifying different ecotypes of Coilia ectenes in the Yangtze Basin, China
(Elsevier, 2012)The variability in otolith shape of the tapertail anchovy Coilia ectenes was investigated as a tool for identifying its different ecotypes. The outlines of 350 sagittal otoliths of known ecotypes collected from seven ... -
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 ... -
Enhanced abundance of tintinnids under elevated CO2 level from coastal Bay of Bengal
(Springer, 2012)The role of microzooplankton (MZP) in the pelagic trophodynamics is highly significant, but the responses of marine MZP to increasing CO2 levels are rather poorly understood. Hence the present study was undertaken to ... -
Fungi and their role in corals and coral reef ecosystems
(Springer, 2012)Fungi in coral reefs exist as endoliths where they penetrate carbonate structures, endobionts where they are associated with living organisms such as corals, sponges and holothurians, as saprotrophs in the coral mucus, ... -
Bleaching and secondary threats on the corals of Palk Bay: A survey and Proactive conservation needs
(NISCAIR (CSIR), 2012)A survey on bleaching and the secondary threats on bleached corals in the selected sites of Palk-Bay were conducted during May and June 2010. Massive corals represented by the genera Porites, Goniopora, Favia were bleached ... -
Estimation of mean grain size of seafloor sediments using neural network
(Springer, 2012)The feasibility of an artificial neural network based approach is investigated to estimate the values of mean grain size of seafloor sediments using four dominant echo features, extracted from acoustic backscatter data. ... -
Nearshore currents along the Karnataka coast, west coast of India
(Multi-Science Publishing, 2012)Measured current data at 7 locations and tide data at 3 locations during the pre-summer monsoon period along the west coast of India is used in the study. The surface currents during March showed a predominant northward ... -
Return period estimates of extreme sea level along the east coast of India from numerical simulations
(Springer, 2012)Estimates of return periods of extreme sea level events along the coast are useful for impact assessment. A vertically integrated 2D model was developed for the simulation of storm surges in the Bay of Bengal. The bathymetry ... -
Role of environmental heterogeneity in structuring the macrobenthic community in a tropical sandy beach, west coast of India
(Springer, 2012)In most ecosystems, community structure emerges as a result of the complex interaction between biotic and environmental variables. Sandy beaches connected to adjacent ecosystem like estuaries/creeks provide an opportunity ... -
