A quantitative analysis of fine scale distribution of intertidal meiofauna in response to food resources
(NISCAIR, CSIR, 1996)Fine scale vertical and spatial distribution of meiofauna in relation to food abundance was studied in the intertidal sediment at Dias Beach. The major abiotic factors showed significant changes and progressive fine scale ... -
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 ... -
Coral mortality in reefs: The cause and effect; A central concern for reef monitoring
(M.S. Swaminathan Res. Found., Chennai (India), 1997)The primary causal agents for the destruction of corals are the abiotic and/or biotic agents or a combination of both. The abiotic factors that are responsible are bioerosion, sedimentation, eutrophication and pollution, ... -
Coral reef surveys in India
(University of Guam Marine Laboratory, 1993)This paper briefly describes the history of coral reef surveys in India. All the surveys done so far have used simple techniques, but they have been quite effective in highlighting the damages to reefs in the short-term ... -
Crowning corals
(NISCAIR, CSIR, 1997)Biodiversity of coral reefs is responsible for productivity in the sea and these coral reefs are built mainly by corals containing a calcium-carbonate skeleton. The reef building corals are the hermotypic corals harbouring ... -
Distribution of living planktonic foraminifera in the coastal upwelling region of Kenya, Africa
(CSIR-NISCAIR, 1988)Seventeen planktonic foraminiferal species have been encountered in the plankton samples collected off the Kenya coast; the most abundant species are Globigerinella aequilateralis, Globigerinoides ruber, G. sacculifer, ... -
Foraminiferal fauna from the Cochin backwaters: Biological indicators of man-made changes in the environment
(K.R. Publishers, Udaipur, 1996)Sixty foraminiferal species belonging to 38 genera and 23 families have been recorded from grab sediments of the Cochin backwaters. Of all the species Ammonia baccarii is the most dominant and successful form in the throes ... -
Microscale response of sediment variables to benthic disturbance in the Central Indian Ocean Basin
(Taylor and Francis, 2000)The response of sediment bacteria and biochemical variables to benthic disturbance was investigated in the Central Indian Ocean Basin from cores at nine stations. Generally, bacterial density and biochemical variables ...
