Estimation of carbonate concentration and characterization of marine sediments by Fourier transform infrared spectroscopy.
(Elsevier, 2014)Fourier Transform Infrared Spectroscopy (FTIR) is a well established method for the characterization of mineralogical and geochemical properties of marine sediments. Understanding the biogeochemical changes in marine ... -
Characterizing slope morphology using multifractal technique: a study from the western continental margin of India.
(Springer, 2014)Here, we present the slope configuration of the submarine gullies, ridges and the adjacent slump zone off Goa, along the western continental margin of India utilizing multibeam bathymetric and single-channel seismic data. ... -
Environmental characteristics of tropical coral reef-seagrass dominated lagoons (Lakshadweep, India) and implications to resilience to climate change.
(Springer, 2014)Environmental characteristics of the coral reef-seagrass ecosystem of selected Lakshadweep Islands (India) were assessed with a view to understanding the future climate change scenario in the region. Images obtained from ... -
Mixed layer variability and chlorophyll a biomass in the Bay of Bengal.
(Published by Copernicus Publications, 2014)The mixed layer is the most variable and dynamically active part of the marine environment that couples the underlying ocean to the atmosphere and plays an important role in determining the oceanic primary productivity. ... -
Interactions of mercury with different molecular weight fractions of humic substances in aquatic systems.
(Springer, 2014)Interactions of mercury (Hg) with different molecular weight fractions of humic substances (HS) play an important role in controlling distribution, diffusion, speciation, and bioavailability of Hg in natural systems. This ... -
A modeling study of the processes of surface salinity seasonal cycle in the Bay of Bengal.
(AGU, 2014)In response to the Indian Monsoon freshwater forcing, the Bay of Bengal exhibits a very strong seasonal cycle in sea surface salinity (SSS), especially near the mouths of the Ganges-Brahmaputra and along the east coast of ... -
Palynological record of tropical rain forest vegetation and sea level fluctuations since 140 ka from sediment core, south-eastern Arabian sea.
(Elsevier, 2014)Palyno-chronological study of a 552 cm deep sediment core from the south-eastern Arabian Sea covers a time span of ~ 140 ka. The age estimate is based on oxygen isotopic data of planktic foraminifera. Six zones were ... -
Evaluation of impairment of DNA in marine gastropod, Morula granulata as a biomarker of marine pollution.
(Elsevier, 2014)The impairment of DNA in marine gastropod Morula granulata was evaluated in terms of the loss of DNA integrity in the species as a measure of the impact of genotoxic contaminants prevalent in the marine environment along ... -
Identification and characterization of tsunami deposits off southeast coast of India from the 2004 Indian Ocean tsunami: Rock magnetic and geochemical approach.
(Indian Academy of Sciences, 2014)The December 2004 Indian Ocean Tsunami (IOT) had a major impact on the geomorphology and sedimentology of the east coast of India. Estimation of the magnitude of the tsunami from its deposits is a challenging topic to be ... -
Bioactive cembrane derivatives from the Indian Ocean soft coral, Sinularia kavarattiensis.
(Published by MDPI AG, 2014)Marine organisms and their metabolites represent a unique source of potential pharmaceutical substances. In this study, we examined marine-derived substances for their bioactive properties in a cell-based Chikungunya virus ... -
Transport of dissolved nutrients and chlorophyll a in a tropical estuary, southwest coast of India.
