    • Carbon in tundra soils in the Lake Labaz region of arctic Siberia 

      Gundelwein, Andreas; Müller-Lupp, Thomas; Sommerkorn, Martin; Haupt, Erhard T.K.; Pfeiffer, Eva-Maria; Wiechmann, Horst (Blackwell Publishing2007-03-29)
      Large amounts of carbon are stored in permafrost-affected soils of the Arctic tundra. The quantity, distribution and composition of this carbon are important, because much of the carbon is likely to be released as a result ...
    • Pedogenic carbonates as a proxy for palaeo-CO2 in the Palaeozoic atmosphere 

      Quast, Andres; Hoefs, Jochen; Paul, Josef (Elsevier2006)
      According to a model by Cerling (1991, 1999), the carbon isotope composition of calcretes should depend on the soil type and the CO2-concentration in the atmosphere. We have tested Cerling’s model by investigating 14 ...
