Contributions of terrestrial organic carbon to northern lake sediments
Abstract Sediments of northern lakes sequester large amounts of organic carbon (OC), but direct evidence of the relative importance of their sources is lacking. We used stable isotope ratios of nonexchangeable hydrogen ( δ 2 H n ) in topsoil, algae, and surface sediments in order to measure the rela...
