A novel approach for the analysis of lignin in geochemical samples has been developed as an alternative to alkaline CuO oxidation procedure first 1982. The new utilizes microwave digestion technology, opposed conductive heating, carry out oxidative hydrolysis six oxygen-free atmosphere at 150 °C 90 min. Ethyl acetate is used extraction solvent place diethyl ether. Additionally, method incorporates a simplified that minimizes handling and amount glassware needed. Under these conditions,...
We investigated the export of particulate organic matter (POM) to ocean by two contrasting small, mountainous rivers, Umpqua and Eel Rivers, collecting suspended sediment samples over a range discharges analyzing them for variety constituents, including carbon, nitrogen, biomarkers with distinct biochemical sources, isotopic compositions (δ 13 C Δ 14 C). Concentrations all measured constituents in both rivers increased as function discharge, resulting their being dominated short‐lived,...
Abstract Bottom trawling grounds have been expanding to deeper areas of the oceans since mid‐XXth century, and mitigating strategies aimed protect fish stocks, such as temporal closures, recently implemented. Here we investigated biogeochemical properties sediment from a deep‐sea ground in Palamós Canyon (NW Mediterranean) assess effects 2‐months closure recovery sedimentary organic matter. In comparison untrawled areas, continuous erosion mixing led coarser reworked sediments impoverished...
As part of the International Polar Year research program, we conducted a survey surface marine sediments from box cores along section extending Bering Sea to Davis Strait via Canadian Archipelago. We used bulk elemental and isotopic compositions, together with biomarkers principal components analysis, elucidate distribution terrestrial organic matter in different regions North American Arctic margin. Marked regional contrasts were observed carbon loadings, highest values (≥1 mg C m −2...
