First phase monitoring studies of simulated benthic disturbance delineating movement of fine particles in the Central Indian Basin
(Taylor and Francis, 2005)
Benthic disturbance due to future deep-sea polymetallic nodule mining would involve extensive sediment plume generation and resedimentation on the sea floor. In order to evaluate the effects of resedimentation on benthic ...
Rare-earth elements and uranium in phosphatic nodules from the continental margins of India
(Society for Sedimentary Geology (SEPM), Tulsa, USA, 2000)
A sediment core collected from a bathymetric high off Goa on the western continental margin of India has yielded phosphatic nodules at various subsurface depths (at 110, 150, 305 355, 435, 500, 505 and 525 cm). The nodules ...
Major, trace, and rare earth elements in the sediments of the Central Indian Ocean Basin: Their source and distribution
(Taylor and Francis, 2001)
The distribution maps of elements show that highest concentrations of Mn, Cu, Ni, Zn, Co, and biogenic opal in the surface sediment occurs between 10 degrees S and 16 degrees S latitude, where diagenetic ferromanganese ...
Echo-waveform classification using model and model free techniques: Experimental study results from central western continental shelf of India
(Marine Technology Society, 2005)
Seafloor classifications and characterization using acoustic backscatter data from the central western continental shelf of India is presented in this work. Single beam sea-floor echo data using two frequencies: 33 kHz and ...
Drift pumice in the central Indian Ocean Basin: Geochemical evidence
(Elsevier, 2008)
Abundant white to light grey-coloured pumice without ferromanganese oxide coating occurs within the Quaternary sediments of the Central Indian Ocean Basin (CIOB). Two distinct groups of pumice are identified from their ...
Heavy metal accumulation in a flow restricted, tropical estuary
(Elsevier, 2005)
Levels of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn), organic carbon content and textural characteristics in the surficial sediments of Cochin estuary (SW coast of India) and adjacent coast are presented. ...
Clay minerals and Sr-Nd isotopes of the sediments along the western margin of India and their implication for sediment provenance
(Elsevier, 2003)
Mineralogy and Sr-Nd isotopic composition of the less than 2-m fraction of the Holocene and late Pleistocene sediments from 12 gravity cores collected along the western margin of India were used to delineate the provenance ...
Alterations in geochemical associations in artificially disturbed deep-sea sediments
(Taylor and Francis, 2005)
In view of the role of sediment geochemistry in regulating the benthic ecosystem, diagenetic remobilization of dissolved constituents, bottom water redox, and regeneration of benthic fluxes, surficial sediments in and ...
Constraints in using Cerium-animaly of bulk sediments as an indicator of paleo bottom water redox environment: A case study from the Central Indian Ocean Basin
(Elsevier, 2005)
The total rare earth elements (Sigma REE) abundance along with major and a range of trace element chemistry of twenty-eight sub-sections in a 5 m long sediment core (AAS-05/GC-02) from the Central Indian Ocean Basin shows ...
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 ...
