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 ...
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
(Elsevier, 2003)
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
(Elsevier, 2012)
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
(Elsevier, 1998)
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 ...
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 ...
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 ...
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 ...
Himalayan sedimentary pulses recorded by silicate detritus within a ferromanganese crust from the Central Indian Ocean
(Elsevier, 2003)
A Central Indian Ocean deep-water seamount hydrogenous ferromanganese crust (SS663-Crust) contains variable (7-23%) amounts of detrital material (silicate-detritus). Taking into account the growth rate of the authigenic ...
Coupling between suboxic condition in sediments of the western Bay of Bengal and southwest monsoon intensification: A geochemical study
(Elsevier, 2013)
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 ...
