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.
(Springer, 2014)Intra-tidal variability in the transport of materials through the Cochin estuary was studied over successive spring and neap tides to estimate the export fluxes of nutrients and chlorophyll a into the adjoining coastal ... -
Temporal variation in macroinvertebrates associated with intertidal sponge Ircinia fusca (Carter 1880) from Ratnagiri, West coast, India.
(CSIR-NISCAIR, 2014)Temporal variation of macrofauna associated with a marine sponge, Ircinia fusca was studied from a tropical rocky shore along the West coast of India. Triplicate sponge samples (~100 g) were collected from January to ... -
Seasonal variability of beach characteristics between Candoliam and Colva coast, Goa, India.
(Centre for Geotechnology, MSU, 2014)The aim of the present study was to investigate the seasonal impact on beach dynamics and the status of heavy mineral distribution along the study area. Beach profile measurements were made in 7 profiling sites between ... -
First record of the Calanoid Copepod Pseudodiaptomus serricaudatus (Scott, T. 1894), (Copepoda: Calanoida: Pseudodiaptomidae) in the equatorial Indian ocean.
(Asian Fisheries Society, 2014)Pseudodiaptomus serricaudatus (Scott, T. 1894), a planktonic copepod belonging to the family Pseudodiaptomidae, though has worldwide distribution, has been reported only from estuarine and coastal waters. This is the first ... -
Coastal processes and longshore sediment transport along Kundapura coast, central west coast of India.
(Elsevier, 2014)Longshore sediment transport (LST) is one of the main factors influencing coastal geomorphology. This study examines the variation in the LST estimate using four well known formulae and the sensitivity of wave parameters ... -
Detection and monitoring of two dust storm events by multispectral modis images.
(JERAD Publications, 2014)During a dust storm event, loose sand/dust from a dry area is picked up and tossed into the air. These particles get together and form a layer of dust. These layers carry large amount of dust from one place to another and ... -
Nutrients, hypoxia and mass fishkill events in Tapi estuary, India.
(Elsevier, 2014)From 1983 to 2011, dissolved oxygen (DO) conditions in the Tapi Estuary changed from normoxic to hypoxic due to increased and untreated discharge of sewage. Both tidal and day–night variations of DO were best explained by ... -
Production, biochemical characterization and detergents application of keratinase from the marine actinobacterium Actinoalloteichus sp. ma-32.
(AOCS, 2014)The present study is the first report on poultry feathers as a novel, inexpensive substrate for the production of a thermo- and detergent stable keratinase from a marine actinobacterium belonging to the genus Actinoalloteichus. ... -
Deterioration in the biodiversity of copepods in sewage laiden creeks of Mumbai coast, west coast of India: A statistical approach.
(Council for Innovative Research, 2014)The coastal waters of Mumbai is known to receive copious amount of waste from the adjacent creeks and bays. Effluents from various industries including nuclear and thermal power stations are discharged into the Mumbai ... -
Quantitative estimation of sediment erosion and accretion processes in a micro-tidal coast.
(Elsevier, 2014)Spatio-temporal cross-shore profiles and textural characteristics are the key parameters for understanding dynamics of the inter-tidal sedimentary environment. This study describes short-term dynamics of the inter-tidal ... -
