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 ...
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. ...
Late Quaternary changes in depositional processes along the western margin of the Indus Fan
(Springer, 2008)
Detailed sedimentological, geochemical and isotopic analyses were carried out on sediment samples from ODP Site 720A on the Indus Fan, Arabian Sea. High values of calcium carbonate associated with low values of Al and Ti ...
Deep-sea fungi
(ASM Press, 2008)
The deep-sea environment, despite being rich in mineral nutrients and near-saturation levels of oxygen, because of its darkness is not conducive to photosynthesis, the process that sustains life on earth. If a liigh abundance ...
Depth anomalies in the Arabian Basin, NW Indian Ocean
(Springer, 2008)
Unreported depth anomalies in the Arabian Basin, northwest Indian Ocean is presented previously, to provide constraints on the evolution of the oceanic lithosphere of that basin. The depth anomaly reported in this study ...
Marine geophysical investigations across the submarine canyon (Swatch-of-No-Ground), northern Bay of Bengal
(Indian Academy of Science, 2008)
Multibeam swath bathymetry, gravity and magnetic investigations were conducted across the major delta front canyon known as Swatch-of-No-Ground in the northern Bay of Bengal. The study reveals that the canyon is a 300 m ...
Carbohydrates, uronic acids and alkali extractable carbohydrates in contrasting marine and estuarine sediments: Distribution, size fractionation and partial chemical characterization
(Elsevier, 2008)
Concentration, size fractionation and monosaccharide composition of carbohydrates and uronic acids were investigated in contrasting sediments of the Mandovi estuary (ME), Arabian Sea (AS) and the Bay of Bengal (BOB). ...
Biogeochemistry of the surficial sediments of the western and eastern continental shelves of India
(Coastal Education and Reserch Foundation, 2008)
Even though continental margins cover only about 7-9 % of the world ocean area, they are important sites for organic carbon accumulation and hence play a major role in biogeochemical carbon cycling. Surface sediments from ...
Abiotic oxidation of pyrite by Fe(III) in acidic media and its implications for sulfur isotope measurements of lattice-bound sulfate in sediments
(Elsevier, 2008)
We have evaluated the relative importance of Fe sup(3+) to dissolved oxygen in pyrite oxidation, and its implications for measuring an accurate sulfur isotope composition (delta Sup(34) S) in trace sulfates extracted from ...
210Pb, 230Th, and 10Be in Central Indian Basin seamount sediments: Signatures of degassing and hydrothermal alteration of recent origin
(Wiley, 2008)
Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ...
