Christian Koeberl, Leiter des Departments für Lithosphärenforschung der Universität Wien, ist vor kurzem aus der sibirischen Arktis zurückgekehrt. Er ist einer der Projektleiter des vor wenigen Wochen im Rahmen des International Continental Scientific Drilling Program (ICDP) durchgeführten Tiefbohrprojektes am Elgygytgyn-Kratersee. Ziel der Unternehmung ist es, durch Analyse der Bohrkerne neue Erkenntnisse im Bereich der Impaktforschung, aber auch zur arktischen Klimaentwicklung zu gewinnen. Die Impaktbrekzien werden unter der Leitung von Christian Koeberl im Rahmen eines FWF-Projektes an der Universität Wien untersucht.
Der Elgygytgyn-See ist vor ca. 3,6 Millionen Jahren durch einen Meteoriteneinschlag entstanden.
