    • Efficient Extraction of Past Seawater Pb and Nd Isotope Signatures From Southern Ocean Sediments 

      Huang, H.ORCIDiD; Gutjahr, M.ORCIDiD; Kuhn, G.ORCIDiD; Hathorne, Ed C.ORCIDiD; 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 ...

    • Recycling and Burial of Biogenic Silica in an Open Margin Oxygen Minimum Zone 

      Dale, A. W.ORCIDiD; Paul, K. M.ORCIDiD; Clemens, D.ORCIDiD; Scholz, F.; Schroller‐Lomnitz, U.; Wallmann, K.; Geilert, S.ORCIDiD; Hensen, C.ORCIDiD; Plass, A.; Liebetrau, V.ORCIDiD; Grasse, P.ORCIDiD; Sommer, S. (Global Biogeochemical Cycles, 2021-02-17)
      An extensive data set of biogenic silica (BSi) fluxes is presented for the Peruvian oxygen minimum zone (OMZ) at 11°S and 12°S. Each transect extends from the shelf to the upper slope (∼1,000 m) and dissects the permanently ...

    • Sediment Properties Drive Spatial Variability of Potential Methane Production and Oxidation in Small Streams 

      Bodmer, P.; Wilkinson, J.; Lorke, A.ORCIDiD (Journal of Geophysical Research: Biogeosciences, 2020)
      Emissions of the potent greenhouse gas methane (CH4) from streams and rivers are a significant component of global freshwater methane emissions. The distribution of CH4 production and oxidation within stream sections and ...

    • Silicon Isotopes in an EMIC's Ocean: Sensitivity to Runoff, Iron Supply, and Climate 

      Dietze, H.ORCIDiD; Löptien, U.ORCIDiD; Hordoir, R.ORCIDiD; Heinemann, M.; Huiskamp, W.ORCIDiD; Schneider, B.ORCIDiD (Paleoceanography and Paleoclimatology, 2020)
      The isotopic composition of Si in biogenic silica (BSi), such as opal buried in the oceans' sediments, has changed over time. Paleorecords suggest that the isotopic composition, described in terms of δ30Si, was generally ...
