the mandovi estuary is highly influenced by mining and tourism related activities in the centralwest coast of india. vertical fluxes and accumulation of petroleum hydrocarbons (phcs) in three sedimentcores (d1, c1 and og) from the mandovi estuary were assessed using ultra-violet fluorescence (uvf)spectroscopy. the range of phcs values in estuarine sediments varied from 5.4 to 12.34 μg/g enrichm...
a comprehensive evaluation of the residual levels of organochlorine insecticides (ocis) in the sediment cores of cochin estuarine system (ces) is highlighted in this research article. it assessed the distribution pattern and impact of these xenobiotics in this environmental niche. fifteen persistent organochlorine compounds (ocs) were quantitatively analysed in the six sediment core samples col...
this article present the result from a study of two sediment cores collected from theenvironmentally distinct zones of ces. accumulation status of five toxic metals: cadmium (cd), chromium(cr), cobalt (co), copper (cu) and lead (pb) were analyzed. besides texture and chns were determined tounderstand the composition of the sediment. enrichment factor (ef) and anthropogenic factor (af) wereused ...

A sediment core spanning approximately 1,600 years was collected from a lake on Ardley Island, Antarctica. The sediment core had been greatly influenced by penguin guano. Using molecular methods, the chitinolytic bacterial community along the sediment core was studied over its entire length. Primers targeting conserved sequences of the catalytic domains of family 18 subgroup A chitinases detect...
Vibracoring is a subsurface sediment acquisition (sediment coring) technique (Pierce and Howard, 1969; Howard and Frey, 1975; dreher et al., 2008) that returns sediment preserved within its stratigraphic and sedimentologic context. This process (see appendix 1) generates a continuous, contiguous sediment sample at a point by vibrating an aluminum core barrel vertically into the sediment (fig. 1...

The microbial community response to petroleum seepage was investigated in a whole round sediment core (16 cm length) collected nearby natural hydrocarbon seepage structures in the Caspian Sea, using a newly developed Sediment-Oil-Flow-Through (SOFT) system. Distinct redox zones established and migrated vertically in the core during the 190 days-long simulated petroleum seepage. Methanogenic pet...
