Constraints in using Cerium-animaly of bulk sediments as an indicator of paleo bottom water redox environment: A case study from the Central Indian Ocean Basin
(Elsevier, 2005)The total rare earth elements (Sigma REE) abundance along with major and a range of trace element chemistry of twenty-eight sub-sections in a 5 m long sediment core (AAS-05/GC-02) from the Central Indian Ocean Basin shows ... -
Evidence of Himalayan erosional event at approx. 0.5 Ma from a sediment core from the equatorial Indian Ocean in the vicinityof ODP Leg 116 sites
(Elsevier, 2005)A sediment core collected from an area _100 miles south of the ODP Leg 116 (distal Bengal Fan) in the equatorial Indian Ocean was investigated for microfossils, mineralogy, mineral chemistry, magnetic susceptibility, grain ... -
Excess aluminum in deep sea sediments of the Central Indian Basin
(Elsevier, 1999)The aluminum concentration in the marine sediments has long been considered an indicator of terrigenous abundance. The Al/Ti values (48.5) of the Central Indian Basin subsurface siliceous sediment are up to three times ... -
Geochemistry of ferromanganese micronodules and associated Mn and trace metals diagenesis at high terrigenous depositional site of middle fan region, Bay of Bengal
(Elsevier, 2003)The influence of sedimentation on the morphology, growth and geochemistry of the micronodules, and on Mn enrichment in the sediments of the Bay of Bengal has been evaluated. Mn accumulation is 307-219 mg cm u2 kyr u-1 in ... -
Mineral resources
(Oxford and IBH, New Delhi, 2001)Marine minerals have been center of attraction to mankind since ancient times. The technological advances in the recent years show that the retrieval of underwater minerals from deep-sea can no longer be a dream. Marine ... -
Organic carbon-sulfur relationships in sediment cores from the western and eastern continental margins of India
(Elsevier, 1994)Two sediment cores from the western continental margin (WMI, WM2) and one core from the eastern continental margin (EM) of India have been analysed to determine the relativ importance of factors such as oxidizing/reducing ... -
Sediment texture, distribution and transport on the Ayeyarwady continental shelf, Andaman Sea
(Elsevier, 2005)The Ayeyarwady continental shelf is a complex sedimentary system characterized by large sediment influx (N360 million ton/yr), a wide shelf (N170 km), a strong tidal regime (7 m maximum tidal range), and incised by the ... -
Superficial mineral resources of the Indian Ocean
(Elsevier, 1984)The sea floor of the Indian Ocean and the continental margins bordering the ocean are covered by a wide variety of terrigenous, biogenous and anthigenic mineral deposits. The biogenous deposits in the Indian Ocean comprise ... -
Variation of paleo-productivity and terrigenous input in the eastern Arabian Sea during the past 100 ka
(Geological Society of India, 2013)A 4.1m long sediment core from the eastern Arabian Sea is studied using multiple geochemical proxies to understand the variation of productivity and terrigenous matter supply during the past 100 ka. The temporal variation ... -
Weekly observations on dispersal and sink pathways of the terrigenous flux of the Ganga-Brahmaputra in the Bay of Bengal during NE monsoon
(Elsevier, 2005)The analyses of 64 sequential satellite images (October 1999-March 2001) of Indian Remote Sensing Satellite IRS-P4 ocean color monitor (OCM) (bands around 490, 555, and 670 nm) for total suspended matter (TSM), synchronous ...
