Untersuchungen zur Rekonstruktion des Partialdruckes von Kohlendioxid anhand von Coccolithophoridenblüten im Nordatlantik : Biomarker Alkenone und deren Kohlenstoffisotopie
The dissertation deals with methodological and field studies of alkenones and their carbon isotopes in the North Atlantic (Madeira Basin). The methodological studies focussed on comparison of measurements with gas chromatography with flame ionisation detection and gas chromatography coupled to mass...
