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 ... -
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 ... -
FiveS rRNA sequences and fatty acid profiles of colourless sulfur-oxidising bacteria
(Publ. and Inf. Dir., New Delhi, India, 1994)Colourless sulfur-oxidising bacteria have been encountered extensively in the oxygen minimum layers of the Arabian Sea. These oligotrophs have been known to mediate nitrogen cycle reductively even under autotrophic conditions. ... -
Manganese micronodules: A possible indicator of sedimentary environments
(Elsevier, 1993)Manganese micronodule distribution, size, internal features and chemical composition as well as the composition of associated sediments have been determined in eight sediment cores taken from the siliceous ooze area of the ... -
Paleoclimatic and diagenetic history of the Late Quaternary sediments in a core from the southeastern Arabian Sea: Geochemical and magnetic signals
(The Oceanographic Society of Japan, 2010)Geochemical and rock-magnetic investigations were carried out on a sediment core collected from the SE Arabian Sea at 1420 m depth in oxygenated waters below the present-day oxygen minimum zone. The top 250 cm of the core ... -
Sulfur cycle
(Elsevier, 2008)Microbes, especially bacteria, play an important role in oxidative and reductive cycle of sulfur. The oxidative part of the cycle is mediated by photosynthetic bacteria in the presence of light energy and chemosynthetic ... -
Truce with oxygen - A naerobiosis outcompete aerobiosis in the Antarctic lacustrine bacteria
(Current Science Association, Bangalore, India, 1999)The total number of bacteria counted directly by epifluorescent microscopy showed that they ranged from 10 sup(8)-10 sup(-1) in Antarctic lake water samples. The percentages of retrievable viable counts (RVC) of anaerobic ...
