The main objective of this projekt is to reveal the geomagnetic field behavior of excursions during the last about 60 ka with high temporal resolution based on magnetostratigraphic investigation of selected arctic marine sediment cores. High-quality directional and relative paleointensity data from different high-latitude sites shall contribute detailed full-vectorial information about the behavior of the geodynamo in space and time to the SPP. Detailed rock magnetic as well as accompanying sedimentological and geochemical studies shall be performed in order to validate the quality of the obtained records. In addition, numerous absolute ages shall be derived with the accelerator mass spectrometry (AMS) 14C method in order to provide a detailed age model of the investigated sediments.
