Eisschild wächst von unten

(PresseBox) (Zurich, )
Anfrieren von Wasser am Grund des Eisschildes kann die federförmigen Strukturen erklären, welche mithilfe von modernen Radarmessungen in den letzten Jahren entdeckt worden sind.

Bislang rätselte man über die Entstehung und Grösse dieser spektakulären Formen und gefalteten Schichten im Eis. Das Ausmass der beobachteten Eisstrukturen kann bis zur Hälfte der Eisdicke, gegen 1000 Meter, betragen und eine Länge von einigen 10 Kilometern erreichen.

Entstehung der Schichtstrukturen am Computer reproduziert

Ein Team von Forschenden der Universität Zürich, Schweiz, und des British Antarctic Survey, England, konnte die Entstehung dieser Altersschichten am Computer reproduzieren. Sie simulierten das Anfrieren am Grund eines Eisschildes.
