Sediment redistribution during simulated benthic disturbance and its implications on deep seabed mining
(Pergamon, 2001)
A benthic disturbance experiment was conducted in the Central Indian Basin to evaluate the possible effects of sediment redistribution on marine ecosystem during deep-sea mining. The analyses of disturbance features on the ...
New sequential separation procedure for Sr, Nd and Pb isotope ratio measurement in geological material using MC-ICP-MS and TIMS
(The Geochemical Society of Japan, 2008)
A new 3-step sequential separation chemistry for Sr, Nd and Pb from silicate samples, which is suitable for isotope analysis by MC-ICP-MS as well as TIMS, has been developed. The chemistry is designed to minimize the number ...
Processes of formation of ferromanganese manganese nodules and crusts
(National Institute of Oceanography, India, 2007)
Changes in nutrient, dissolved oxygen and total suspended matter during simulated placer mining
(Macmillan, India, 2007)
In order to study the impact of placer mining on shallow coastal waters, a simulated sand mining experiment was carried out in Kalbadevi, Ratnagiri, west coast of India, which is recognized as one of the future sand mining ...
Seafloor and sediment characteristics in INDEX AREA
(Metal Mining Agency of Japan, 1997)
Seafloor surveys and sediment sampling during the INDEX (Indian Deep-Sea Environmental Experiment) studies in the Central Indian Basin, resulted in identification of Test and Reference Areas, as well of establishment of ...
Geochemistry of sediments
(Oxford and IBH, New Delhi, 2001)
Considering the potential of elemental data in marine sediments as diagnostic tools of various geological and oceanographic processes, sediment geochemical data from the Indian Ocean region has been reviewed in this article. ...
Distribution of baroduric, psychrotrophic and culturable nitrifying and denitrifying bacteria in the Central Indian Basin
(National Institute of Ocean Technology, 2004)
The abundance of baroduric, culturable nitrifying and denitrifying bacteria in the deep-sea cores of Central Indian Basin (CIB) at ca 5000 m depth was investigated. Analysis of 8 cores, sampled between 10 degrees 00 minutes ...
Nature, source and composition of volcanic ash in sediments from a fracture zone trace of Rodriguez Triple Junction in the Central Indian Basin
(Elsevier, 2006)
Volcanic glasses associated with pumice, micro nodules and palagonite like lithic fragments were recovered from a volcanic terrain in a fracture zone defined as Rodriguez Triple Junction trace in the Central Indian Basin. ...
Anomalous phase association of REE in ferromanganese crusts from Indian mid-oceanic ridges: Evidence for large scale dispersion of hydrothermal iron
(Elsevier B.V., 2020)
Ferromanganese crusts collected at selected locations along the ~7000 km long stretch of Carlsberg, Central Indian and Southwest Indian ridges are studied for bulk geochemical composition and distribution of rare earths ...
Signatures of rare-earth elements in banded corals of Kalpeni atoll-Lakshadweep archipelago in response to monsoonal variations
(NISCAIR, CSIR, 1996)
Concentrations of rare-earth elements (REE) have been determined in seasonal bands of Porites species collected from the Lakshadweep lagoon. Total REE (REE) are very low (less than 3 ppm) in these corals. Seasonal variations ...
