Wissenschaftliches Interesse

Auf Expeditionen in den Ozean untersuche ich den Stoffumsatz an kalten Quellen und Schlammvulkanen am Meeresboden, die Entstehung von Gashydraten, den mikrobiellen Abbau organischer Substanzen in Oberflächensedimenten und die Rückführung von Nährstoffen aus den Sedimenten in den Ozean. Darüberhinaus werte ich die in marinen Karbonaten und Evaporiten aufgezeichneten Isotopentrends aus, um die langfristige geochemische Evolution der Ozeane und der Atmosphäre zu rekonstruieren und mit Hilfe numerischer Modelle zu simulieren.
