Reconstruction of past climate conditions over central Europe from groundwater data

Popis výsledku v původním jazyce

Here we present a 30 000 years low-resolution climate record reconstructed from groundwater data. The investigated site is located in the Bohemian Cretaceous Basin, in the corridor between the Scandinavian ice sheet and the Alpine ice field. Noble gas temperatures (NGT), obtained from groundwater data, preserved multicentennial temperature variability and indicated a cooling of at least 5 ? 7 °C during the LGM. This is further confirmed by the depleted ?18O and ?2H values at the LGM. High excess air (?Ne) at the end of the Pleistocene is possibly related to abrupt changes in recharge dynamics due to progression and retreat of ice covers and permafrost. These results agree with the facts that during the LGM permafrost and small glaciers developed in theinner valleys of the Giant Mountains (located in the catchment basin of the aquifers). A temporal decrease of deuterium excess from the preindustrial Holocene to present days is linked to an increase of the air temperatures, and probably
