Geochemistry of deep-sea sediment cores from the Central Indian Ocean Basin
(NISCAIR, New Delhi, 1993)
Four sediment cores from the Central Indian Ocean Basin (CIOB) were studied to characterise the coarse fraction (less than 63 mu), transition metal and major oxide contents. Transition metals (Mn, Cu, Ni, Zn) show enrichment ...
Productivity fluctuations in the southeastern Arabian Sea during the last 140 ka
Detailed analyses of multiple geochemical productivity proxies such as calcium carbonate, biogenic opal, biogenic Ba, organic carbon and total nitrogen have been carried out on a sediment core from the southeastern Arabian ...
Fe speciation and Fe/Al ratio in the sediments of southeastern Arabian Sea as an indicator of climate change
Aluminium, titanium and iron are the major lithogeneous contributors to the marine sediment and their abundance varies strikingly with the intensity of monsoonal precipitation. Al and Ti concentrations in a sediment core ...
Chemistry of surface sediment along a north-south transect across the equator in the Central Indian Basin: An assessment of biogenic and detrital influences on elemental burial on the seafloor
The detailed chemistry of the surface sediment collected along a north-south transect across the equator in the Central Indian Ocean suggest that: biogenic sedimentation north of equator is dominated by carbonate ooze and ...
A note on geochemistry of surface sediments from Krishna-Godavari basin, East Coast of India
(The Geological Society of India, 2008)
A closely spaced 75 surface sediments drawn from ‘Gas Hydrate` Project taken up by National Institute of Oceanography on a regional scale from the Krishna-Godavari Basin (Latitude I5 degrees 35 minutes to 16 degrees 20 ...
Coupling between suboxic condition in sediments of the western Bay of Bengal and southwest monsoon intensification: A geochemical study
Reconstruction of paleo-redox conditions in a radiocarbon (14C) dated sediment core (SK-218/1), covering the past 45 ka (thousand calendar years), collected from the western Bay of Bengal (Lat: 14 degrees 02′N; Long: 82 ...
