WebThe molar C/Fe ratio of the initial solutions was AFhA 0.4, AFhB 1.3, and AFhD 4.2. Coprecipitated ferrihydrites were obtained by dissolving Fe(NO3)3 in forest-floor extract so-lutions of different concentrations and adding 0.1M NaOH under vigorous stirring until a pH of 5 was reached. The molar C/Fe ratio of these initial solutions was CFhA 0.4, WebWe used a combination of porewater and solid phase analysis, as well as a series of sediment incubations, to quantify organic carbon oxidation by dissimilatory Fe reduction, Mn reduction, and sulfate reduction, in sediments from the Skagerrak (located off the northeast coast of Jutland, Denmark).
