Journal ArticleDOI
Fast transformation of iron oxyhydroxides by the catalytic action of aqueous Fe(II)
TL;DR: In this paper, the isotopic exchange between aqueous Fe(II) and iron oxides was investigated using isotope exchange experiments with 55Fe-labeled IR oxides.
Journal ArticleDOI
Karelian shungite—an indication of 2.0-Ga-old metamorphosed oil-shale and generation of petroleum: geology, lithology and geochemistry
TL;DR: In this paper, the authors show that the upper Zaonezhskaya Formation contains an estimated 25×1010 tonnes of organic carbon accumulated within an area of 9000 km2, and the integrated data suggest that the organic material has a biogenic origin.
Journal ArticleDOI
The biogeochemistry, stable isotope geochemistry, and microbial community structure of a temperate intertidal mudflat: an integrated study
Michael E. Böttcher,Britta Hespenheide,Enrique Llobet-Brossa,Christine Beardsley,Ole Larsen,Andreas Schramm,Andrea Wieland,Gerd Böttcher,Ulrike-G. Berninger,Rudolf Amann +9 more
TL;DR: An integrated study, combining biogeochemical, stable isotope, micro-sensor, sedimentological, phase-analytical, and molecular ecological methods, was carried out in April 1998 in a temperate intertidal mud#at (Site Dangast; German Wadden Sea of the southern North Sea).
Journal ArticleDOI
Fine scale remobilisation of Fe, Mn, Co, Ni, Cu and Cd in contaminated marine sediment
Sophie Tankere-Muller,Hao Zhang,William Davison,Niko Finke,Ole Larsen,Ole Larsen,Henrik Stahl,Ronnie N. Glud +7 more
TL;DR: In this article, the concentrations of trace metals in the porewaters were measured at a vertical resolution of 2 mm using the technique of diffusive equilibration in thin-films (DET) and microelectrodes were used to measure concentration profiles of oxygen and pH.
Journal ArticleDOI
Anoxic carbon degradation in Arctic sediments: Microbial transformations of complex substrates
TL;DR: In this paper, the authors explored the effects of substrate complexity on carbon transformations in permanently cold anoxic sediments, by adding four substrates (Spirulina cells, Isochrysis cells, Spirulina and Iso-Ex) to Svalbard sediments.
