Clay minerals as palaeomonsoon proxies: Evaluation and relevance to the late Quaternary records from SE Arabian Sea
(NCAOR, Goa, 2005)
Palaeoclimatic studies are largely dependent on the quality of records and a prudent use of environmental proxy indicators. In this study, the factors affecting the detrital clay minerals in marine environment and their ...
Some geodynamic complexities related to the evolution of Bengal Fan and the neotectonic activity of the south Indian shield
(Current Science Association, Bangalore, 1997)
After three decades of the International Indian Ocean Expedition (IIOE) and in spite of extensive geophysical data collected during the last one decade, the geodynamics of the Bengal Fan and the Peninsular shield at the ...
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 ...
Monitoring the sedimentary carbon in an artificially disturbed deep-sea sedimentary environment
(Springer, 2012)
An area of 0.6 km sup(2) in the manganese nodule field of the Central Indian Basin was physically disturbed and sediments discharged in the near bottom waters to simulate seabed mining and study its impact on benthic ...
Trace elements in near-shore sediments along the east and west coasts of India
(Science and Technology Agency of Japan (JISTEC, STA), Japan, 1999)
To understand the distribution of trace elements and their controlling factors in the coastal regions of India. Some representative sediment samples from the nearshore regions were selected from the east and west coasts ...
Distribution and sources of organic matter in surface sediments of the eastern continental margin of India
(American Geophysical Union, 2013)
The sources and distribution of organic matter (OM) in surface sediments of the eastern continental margin of India, including the region influenced by river discharge, were investigated using content, molar C:N ratios and ...
A note on the Pavonina flabelliformis D'Orbigny (benthic foraminifera) from the Arabian Sea
(Association of Korean Geoscience Societies, 1994)
The detailed study of the inner shelf surface sediments off Karwar (India) revealed the occurrence of a benthic foraminiferal species Pavonina flabelliformis. This is the first report of this species in the Arabian Sea. ...
Ablated tektite from the central Indian Ocean
(Meteoritical Society, Fayetteville, USA, 1996)
A well-preserved ablated (button-shaped) tektite recovered from the surface sediments of the central Indian Ocean lacks flow ridges and has apparently undergone ablation of 6.9 to 7.9 mm. The lack of flow ridges and amount ...
Sources of hydrocarbons in sediments of the Mandovi estuary and the Marmugoa harbour, west coast of India
(Elsevier, 2008)
Surface sediments were collected from various locations of the Mandovi estuary and the Marmugoa harbour, Goa, India. Sediments were analysed for organic carbon (OC), total lipids, n-alkanes concentration and composition. ...
Processes controlling forms of phosphorus in surficial sediments from the eastern Arabian Sea impinged by varying bottom water oxygenation conditions
(Elsevier, 2005)
The surficial sediments from the upper continental slope of the eastern Arabian Sea, impinged by the oxygen minimum zone (OMZ, 150-1200 m water depth), show varying concentrations of the biogenic element phosphorus (P, ...
