  • Abrupt Climate Change
    Among other things, new methods are being developed at PIK that, on the one hand, investigate new aspects in palaeoclimate data, but also cope with the difficulties usually associated with palaeoclimate analyses – such as gaps in the data, age uncertainties, or irregularities in the data sampling. While this is basic research, it is also immediately […]
  • Biomineralisation of calcite by bacterial isolates
    Using stalactite material and fluvialfluvial Durch fließendes Wasser verursacht; zum Beispiel: “Fluviale Sedimente” = durch fließendes Wasser abgelagertes Material. sediments from the Blessberg cave, the diversity and activity of the occuring bacteria and their formation of carbonate minerals were investigated. For this purpose, various techniques such as phylogenetic analyses, bacterial cultivation, electron microscopy, X-ray spectroscopy, confocal […]
  • Climate Zone Shift in central Europe
    The three stalagmites BB-1 to BB-3 were geochemically investigated by GFZ Potsdam, Ruhr-Uni Bochum, PIK Potsdam, Uni Mainz and Northumbria University. The dating was done at the University of Mainz. Stalagmite BB-1 grew 5,600 to 600 years ago, BB-2 6,200 to 3,700 years ago, and BB-3 (although the shortest) 11,200 to 5,300 years ago. At GFZ, […]
  • First Reconstruction of the Holocene Climate
    The first results of the geochemical analyses of the three stalagmites BB-1 to BB-3 already allow conclusions about the climatic changes of the last 14,000 years. A detailed interpretation can be found in the article Climate zone shift in Central Europe.
  • Modelling of karstification
    The strength and speed of karstification depends on various parameters, such as water balance or the existing rocks. A karstification model was used to model how karstification had developed in the area of the Schalkauer Platte and how it will develop in the future. The model shows regional differences in the karstification potential. Especially in the […]
  • Novel methods for studying palaeoclimate dynamics
    At PIK, among other things, new methods are being developed that, on the one hand, can be used to investigate new aspects in palaeoclimate data, but on the other hand can also cope with the difficulties usually associated with palaeoclimate analyses – such as gaps in data series, uncertainties in the dating, or irregularities in the […]
