Mixed response in bacterial and biochemical variables to simulated sand mining in placer-rich beach sediments, Ratnagiri, West coast of India
(Springer, 2012)
The influence of mechanical disturbance of sediment-akin to small scale mining on bacterial community and biochemical variables was investigated at Kalbadevi beach, Ratnagiri, a placer-rich beach ecosystem which is a ...
210Pb, 230Th, and 10Be in Central Indian Basin seamount sediments: Signatures of degassing and hydrothermal alteration of recent origin
(Wiley, 2008)
Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ...
Determination of rare earth, major and trace elements in authigenic fraction of Andaman Sea (Northeastern Indian Ocean) sediments by inductively coupled plasma-mass spectrometry
(Elsevier, 2010)
Downcore variation of rare earth elements (REEs) in the authigenic Fe-Mn oxides of a sediment core (covering a record of last approx. 40 kyr) from the Andaman Sea, a part of the Indian Ocean shows distinctive positive Ce ...
Possible detrital, diagenetic and hydrothermal sources for Holocene sediments of the Andaman backarc basin
(Elsevier, 2008)
Three sediment cores near the spreading axis in the Andaman backarc basin (ABB) were studied for bulk and clay mineralogy, major, trace and rare earth element (REE) geochemistry in bulk and three selective leaches, to ...
Fate of copper complexes in hydrothermally altered deep-sea sediments from the Central Indian Ocean Basin.
(Elsevier, 2014)
The current study aims to understand the speciation and fate of Cu complexes in hydrothermally altered sediments from the Central Indian Ocean Basin and assess the probable impacts of deep-sea mining on speciation of Cu ...
Impacts on surface productivity during sediment dispersal experiment in Central Indian Basin
(Taylor and Francis, 2005)
It is anticipated that in the case of mining of marine minerals, sea floor sediments will be brought up along with the mineral ores and discharged on the surface. These nutrient rich sediments would create a set of different ...
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 ...
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 ...
Monitoring effects of simulated disturbance at INDEX site: Current status and future activities
(International Society of Offshore and Polar Engineers, 2003)
During the Indian Deep-Sea Environment Experiment (INDEX), greater than 6000 cu.m of sediment was resuspended 5 m above seafloor. Data collected from deep-towed photography, sediment traps, sediment coring and CTD operations ...
