Assessment of fungal diversity in deep-sea sediments by multiple primer approach
(Springer, 2012)
Increasing evidence of the fungal diversity in deep-sea sediments has come from amplification of environmental DNA with fungal specific or eukaryote primer sets. In order to assess the fungal diversity in deep-sea sediments ...
Mixed response in bacterial and biochemical variables to simulated sand mining in placer-rich beach sediments, Ratnagiri, West coast of India
(Springer, 2012)
The influence of mechanical disturbance of sediment-akin to small scale mining on bacterial community and biochemical variables was investigated at Kalbadevi beach, Ratnagiri, a placer-rich beach ecosystem which is a ...
Stable nitrogen isotopic ratios of sinking particles and sediments from the northern Indian Ocean
(Elsevier, 2005)
Delta sup(15)N values in modern sediments of the northern Indian Ocean range from less than 4 ppt in the northern Bay of Bengal to greater than 11 ppt in the central Arabian Sea due to the strong spatial variability of ...
Butyltins in the sediments of Kochi and Mumbai harbours, west coast of India
(Elsevier, 2006)
Surface sediment samples were collected from various locations in the Mumbai and Kochi harbours, west coast of India, to assess the presence of butyltin compounds. Tributyltin (TBT) and dibutyltin (DBT) varied from 16 to ...
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 ...
Determination of rare earth, major and trace elements in authigenic fraction of Andaman Sea (Northeastern Indian Ocean) sediments by inductively coupled plasma-mass spectrometry
(Elsevier, 2010)
Downcore variation of rare earth elements (REEs) in the authigenic Fe-Mn oxides of a sediment core (covering a record of last approx. 40 kyr) from the Andaman Sea, a part of the Indian Ocean shows distinctive positive Ce ...
Impact microcrater morphology on Australian microtektites
(Meteoritical Society, 2003)
Scanning electron microscopy of 137 Australian microtekties and fragments from 4 sediments cores in the Central Indian Ocean reveals more than 2000 impact-generated features in the size range of 0.3 to 600 mu m. Three ...
Distribution pattern and morphochemical relationships of manganese nodules from the Central Indian Basin
(Springer, 2001)
In the Central Indian Basin manganese nodule abundance was variable in all sediment types. Mean abundance varied from 1.5 in calcareous ooze to 10.2 kg/m sup(2) in terrigenous-siliceous ooze sediments. Nodule grade and ...
Extensive occurrence and genesis of authigenic carbonates from Krishna-Godavari offshore basin (Bay of Bengal): Possible influence of methane hydrates occurrences.
(Indian Geophysical Union, 2014)
We report here the extensive occurrences of authigenic carbonate nodules/concretions from gas hydrate bearing sediments. Bulk mineralogical compositions by X-Ray diffractometry and EDS (Energy Dispersive Spectrum) analysis ...
Grain size analysis of sediments from the northern Andaman Sea: Comparison of laser diffraction and sieve-pipette techniques
(Coastal Education and Reserch Foundation, 2006)
A comparison has been made of sand, silt, and clay percentage of 118 samples from the Ayeyarwady continental shelf, northern Andaman Sea, measured by the sieve-laser diffraction technique and by classical sieve-pipette ...
