Expedition zu den Methanquellen in Neuseelands Tiefsee

Kieler Meereswissenschaftler wollen Prozesse im Meeresboden besser verstehen

(PresseBox) (Kiel, )
Geophysiker des Kieler Leibniz-Instituts für Meereswissenschaften (IFM-GEOMAR) untersuchen von Anfang März bis Ende April 2011 mit dem deutschen Forschungsschiff SONNE natürliche Methanquellen in der Tiefsee vor Neuseelands Ostküste. Die genauere Kenntnis dieser sogenannten "cold seeps" ermöglicht Aussagen über Prozesse im Meeresboden, über mögliche Rohstoffvorkommen, aber auch über Zusammenhänge von Rutschungen und Gashydraten.

Es blubbert und brodelt im Meer vor Neuseeland. An den Kontinentalhängen, die fast unmittelbar vor der Ostküste der Nordinsel auf bis zu 3000 Meter Tiefe abfallen, liegen zahlreiche Quellen, an denen freies Methangas als Blasenstrom aus dem Meeresboden quillt. Da unterhalb des Meeresbodens auch Gashydrate, also feste Vnkasl-Bwdnpm-Toiolzoqbyio, zfhssg, duacaap lso wovoh andecagdfxqgw.
