Environmental Drivers of Benthic Flux Variation and Ecosystem Functioning in Salish Sea and Northeast Pacific Sediments
The upwelling of deep waters from the oxygen minimum zone in the Northeast Pacific from the continental slope to the shelf and into the Salish Sea during spring and summer offers a unique opportunity to study ecosystem functioning in the form of benthic fluxes along natural gradients. Using the ROV ROPOS we collected sediment cores from 10 sites in May and July 2011, and September 2013 to perfo...
متن کاملEvaluation of Trace Metal Levels in Surface Sediments of the Sergipe River Hydrographic Basin, Northeast Brazil
As distribuições de Co, Cr, Cu, Mn, Ni, Pb, Fe e Al foram investigadas em sedimentos superficiais coletados em 19 sítios da Bacia Hidrográfica do Rio Sergipe, Nordeste do Brasil. Foi definida uma base geoquímica para a região (RGB) usando o ferro como elemento de referência. Fatores de enriquecimento (EF) e índice de geoacumulação (Igeo) foram empregados para determinar a contribuição por orige...

متن کاملCalcareous Nannofossils in Holocene Surface Sediments of the Persian Gulf
The effect of the paleoclimatic and paleoenvironmental changes on the structure of the bioticcommunities are stronger and better recorded in the shelf area than in the open sea. The present study isdevoted to impact of climatic events on some species of calcareous nannofossils. For this reason, 17samples of surface sediments of the Persian Gulf were studied. Preservation of calcareous nannofoss...
متن کاملBioremediation of oil polluted marine sediments: A bio-engineering treatment.
The fate of hydrocarbon pollutants and the development of oil-degrading indigenous marine bacteria in contaminated sediments are strongly influenced by abiotic factors such as temperature, low oxygen levels, and nutrient availability. In this work, the effects of different biodegradation processes (bioremediation) on oil-polluted anoxic sediments were analyzed. In particular, as a potential bio...
