Pre- and post-monsoonal changes in grain size and heavy minerals in the sediments from Kalbadevi Bay, Ratnagiri, west coast of India
(NISCAIR (CSIR), 2011)
Sediments from the Kalbadevi Bay, Ratnagiri collected during January, May and October have been studied for processes responsible for the observed grain size variations and heavy mineral distribution. The study shows ...
Geochemical characterization of the Krishna–Godavari and Mahanadi offshore basin (Bay of Bengal) sediments: A comparative study of provenance
The Krishna–Godavari and Mahanadi rivers drain the east coast of India and deposit the sediment load into the Krishna–Godavari and Mahanadi offshore basins along the western margin of the Bay of Bengal. Here we report the ...
Gas-hydrates in Krishna-Godavari and Mahanadi basins: New data
(Geological Society of India, 2012)
Immobilisation of manganese, cobalt and nickel by deep-sea-sediment microbial communities
(Taylor & Francis, 2011)
Box core samples BC26 and BC36 from geologically different settings were examined to test the hypothesis that autochthonous microbial communities from polymetallic-nodule-rich Central Indian Basin sediments actively ...
Effects of composition of labile organic matter on biogenic production of methane in the coastal sediments of the Arabian Sea
Coastal regions are potential zones for production of methane which could be governed by ecological/environmental differences or even sediment properties of a niche. In order to test the hypothesis that methanogenesis in ...
Phenyltins in Surface Sediments of the Visakhapatnam Harbour, India
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. ...
Geochemical characterisation of major and trace elements in the coastal sediments of India
Thirty-five surface sediment samples from the Indian continental shelf were recovered offshore from the mouths of the major rivers (Brahmaputra, Ganges, Narmada, Tapti, Godavari, Krishna and Cauvery) discharging into the ...
A new spectrofluorometric method for the determination of total arsenic in sediments and its application to kinetic speciation
(Taylor & Francis, 2012)
A simple and sensitive spectrofluorometric method has been developed for the determination of arsenic (As) using rhodamine-B as a fluorescent agent. This method is based on the reaction of As(III) with potassium iodate ...
Sediment Oxygen Demand in Cochin backwaters, a tropical estuarine system in the south-west coast of India
Eutrophication has often been one of the major problems encountered in estuaries and coastal waters. The oxic/anoxic status of an estuary can be effectively determined by measurement of the Sediment Oxygen Demand (SOD). ...
Organic enrichment and benthic fauna–Some ecological consideration.
In the present study, synoptic data on the structure of macroinfauna and total organic content of sediment collected from different sources were analyzed to look for patterns of association consistent with conceptual model ...
