Wykład Jakuba Holušy w ramach projektu IDUB – 27 marca

Zapraszamy na wykład dr. Jakuba Holušy (Uniwersytet Masaryka w Brnie), wizytującego Uniwersytet Wrocławski w ramach programu „profesorów wizytujących” projektu IDUB. Wykład, zatytułowany „Late Pleistocene environmental changes in the Vienna Basin – a place where to different cold-climate aeolian worlds met„, odbędzie się 27 marca 2026 r. (piątek) o godzinie 11:30 w sali 336 (Gmach Główny UWr, III piętro)

Abstrakt wystąpienia: Vienna Basin represents the northwesternmost part of the Carpathian Basin. Aeolian sand accumulations are therefore spread over 1300 km2 in the Vienna Basin, covering >10% of its area. The northernmost part of the Vienna Basin served as a convergence zone for at least two atmospheric circulation patterns. Whilst the wind pattern (westerlies) in most of the Vienna Basin has remained unchanged at least since the Last Glacial Maximum, some of the dunes were clearly formed by winds blowing from north, which were defined as katabatic winds propagating from the Scandinavian Ice Sheet. These winds ceased to exist once the ice sheet retreated further north (probably during the Oldest Dryas). OSL dating results obtained from the two largest dune fields in the Vienna Basin show episodical aeolian activity between 26 ± 2 ka and 13 ± 2 ka, peaking during the Oldest Dryas (16.5 to 14.7 ka). This chronology is in accordance with a pattern described in the rest of the Carpathian Basin.

Dodatkowa infromacja: Po wykładzie odbędzie się spotkanie informacyjne w sprawie możliwości współpracy z Czech Antarctic Research Programme
