• Iron Exports From Catchments Are Constrained by Redox Status and Topography 

      Tittel, JörgORCIDiD; Büttner, OlafORCIDiD; Friese, KurtORCIDiD; Lechtenfeld, Oliver J.ORCIDiD; Schuth, Stephan; von Tümpling, Wolf; Musolff, AndreasORCIDiD (Global Biogeochemical Cycles, 2022-01-18)
      Fe(III) hydroxides stabilize organic carbon (OC) and P in soils. Observations of rising stream Fe concentrations are controversially posited to result from a flushing of iron‐rich deeper soil layers or a decrease of competing ...
    • Oxygen Dependent Temperature Regulation of Benthic Fluxes in Reservoirs 

      Dadi, TallentORCIDiD; Friese, KurtORCIDiD; Wendt‐Potthoff, KatrinORCIDiD; Marcé, RafaelORCIDiD; Koschorreck, MatthiasORCIDiD (Global Biogeochemical Cycles, 2023-04-02)
      Temperature and dissolved oxygen concentration are critical factors affecting the exchange of solutes between sediment and water; both factors will be affected by warming of lakes and thereby influence water quality. ...
    • Trace-element behaviour in sediments of Ugandan part of Lake Victoria: results from sequential extraction and chemometrical evaluation 

      Ribbe, NilsORCIDiD; Arinaitwe, Kenneth; Dadi, TallentORCIDiD; Friese, KurtORCIDiD; von Tümpling, Wolf (Environmental Earth Sciences, 2021-04-12)
      Lake Victoria is the second largest freshwater lake and the largest tropical lake in the world. The transboundary lake has the fastest growing population in its catchment, which can impact the water and sediment quality. ...
