Scanning Electron Microscopic Studies of Fossil Pteropods from the Andaman Sea: Inferences on Carbonate Dissolution
(Indian National Science Academy, 2020)
Among the different microfossils group, pteropods are least studied zooplanktons having delicate aragonitic shells which are very susceptible to dissolution. The present study has been carried out to understand the effect ...
Implications of Microbial Thiosulfate Utilization in Red Clay Sediments of the Central Indian Basin: The Martian Analogy
(John Wiley & Sons, 2019)
Microbial thiosulfate utilization and S-disproportionation could be important mechanisms of sulfate-formations on Earth and Mars. Sulfates on Mars date back to late-Noachian to Hesperian period. In contrast, the large ...
Kinetic and equilibrium based fractionation study of Pb in continental shelf sediment of India
Two independent analytical methods (kinetic and sequential extraction protocols) were used to understand the distribution, stability, and lability of Pb-sediment complexes in Indian continental shelf. The concentrations ...
Alkaline phosphatase: An appraisal of its critical role in c-limited deep-sea sediments of central Indian Basin
(Taylor & Francis Group, 2017)
Alkaline phosphatase (ALP) is a hydrolase that releases phosphate, a crucial nutrient supporting formation of many macromolecules. The oligotrophic sediments of Central Indian Basin (CIB) were examined for the extent of ...
Carbonate delta drift: A new sediment drift type
Based on high-resolution reflection seismic and core data from IODP Expedition 359 we present a new channel-related drift type attached to a carbonate platform slope, which we termed delta drift. Like a river delta, it is ...
Integrated Geochemical and Morphological Data Provide Insights into the Genesis of Ferromanganese Nodules
(Multidisciplinary Digital Publishing Institute- MDPI AG, Basel, Switzerland, 2018)
Ferromanganese nodules grow by precipitation of metals from seawater and/or sediment pore water. The formation of different genetic types depends on the composition and redox conditions of the water and upper sediment ...
A two million year record of low-latitude aridity linked to continental weathering from the Maldives
Indian-Asian monsoon has oscillated between warm/wet interglacial periods and cool/dry glacial periods with periodicities closely linked to variations in Earth�s orbital parameters. However, processes that control wet ...
Refinement of Miocene sea level and monsoon events from the sedimentary archive of the Maldives (Indian Ocean)
International Ocean Discovery Program (IODP) Expedition 359 cored sediments from eight borehole locations in the carbonate platform of the Maldives in the Indian Ocean. The expedition set out to unravel the timing of Neogene ...
Cerium anomaly variations in ferromanganese nodules and crusts from the Indian Ocean
Fifty analyses of rare earth elements as well as mineralogical studies have been carried out on a suite of manganese nodules and crusts from the Central Indian Basin and the Western Indian Ocean. The aim was to identify ...
Indian BIE (Indian Dee-Sea Environment Experiment - INDEX)
(Mar Georesour Geotechnol, 2000)
