Die Rekonstruktion der Oberflächentemperaturen des Ozeans ist ein wichtiger Bestandteil der Paläoklimaforschung. Nun weist ein Team um Sarah Hurley von der Harvard Universität (Cambridge, USA) und Felix Elling vom MARUM - Zentrum für Marine Umweltwissenschaften an der Universität Bremen auf bisher übersehene biologische Aspekte des Paläothermometers TEX86 hin. Diese organischgeochemische Methode nutzen Wissenschaftler_innen, um die Ozeantemperatur in der Erdgeschichte zu ermitteln. Im Meeresboden gelagerte molekulare Fossilien liefern Erkenntnisse auf die Umweltbedingungen der Vergangenheit. Die neue Studie zeigt Folgendes: Nicht nur die Temperatur, sondern auch die Atmungsrate des Mikroplanktons beeinflusst, wie diese molekularen Fossilien zusammengesetzt sind. Seine Ergebnisse hat das Team zxkoy lx Mxbaqqlvdfcmjegmudtg Vwfylwxxcgz wk dyh Bpioyzya Dyfbvkr mz Uhxqrawk (XKIY) bigfbqesusswki.
