Compound-Specific Radiocarbon Analysis of (Sub-)Antarctic Coastal Marine Sediments—Potential and Challenges for Chronologies
Berg, S.; Jivcov, S.; Kusch, S.; Kuhn, G.; Wacker, L.; Rethemeyer, J. (Paleoceanography and Paleoclimatology, 2020)In Antarctic and Subantarctic environments, 14C-based age determination is often challenging due to unknown reservoir effects, low organic carbon contents of sediments, and high contributions of petrogenic (14C-free) carbon ... -
Dating Deep-Sea Sediments With 230Th Excess Using a Constant Rate of Supply Model
Geibert, W.; Stimac, I.; Rutgers van der Loeff, M. M.; Kuhn, G. (Paleoceanography and Paleoclimatology, 2019)We present a dating method for deep-sea sediments that uses the natural radionuclide 230Th (half-life 75,380 years) in analogy to 210Pb with the constant rate of supply (CRS) model. Using an example from the western Indian ... -
Efficient Extraction of Past Seawater Pb and Nd Isotope Signatures From Southern Ocean Sediments
Huang, H.; Gutjahr, M.; Kuhn, G.; Hathorne, Ed C.; Eisenhauer, A. (Geochemistry, Geophysics, Geosystems, 2021-03-16)Radiogenic lead (Pb) and neodymium (Nd) isotope compositions extracted from authigenic phases in marine sediments are sensitive tracers to reconstruct past ocean circulation and water mass mixing. Chemical reductive leaching ...
