Im März 2009 hat das Continental Scientific Drilling Program (ICDP) mit den Bohrungen am Lake El'gygytgyn im nordöstlichen Sibirien begonnen. Dabei handelt es sich um den einzigen bekannten Impaktkrater in vulkanischem Gestein. Mit seiner 300 m langen Sedimentabfolge ist El'gygytgyn aber auch ein einzigartiges Archiv für die Klima- und Umweltgeschichte. Christian Koeberl, Impaktforscher der Universität Wien, leitet die Auswertung der Impakt-Bohrkerne. Er erwartet sich neue Erkenntnisse zur den Veränderungen in der Arktis mit einer bisher nicht erreichten zeitlichen Auflösung sowie zum Verständnis geschockter Vulkanite. Das Forschungsprojekt ist aufgrund der exponierten Lage und der dort vorherrschenden tiefen Temperatur extrem teuer.
