- Abstract:
- Magnetic excursions provide important information about the mechanisms of magnetic field generation in the core, and can be used to correlate climate records. Our recent results suggest that two such excursions are is approximately equal to 10ka in duration, challenging current ideas about the core process that generates them. We propose to test the duration of these events in cores from three ODP legs using existing delta 18 O stratigraphies and new 230Th xs measurements. We will assess the latitudinal variability in the paleomagnetic field during excursions, and test the idea that excursions typically come in doublets. We will also measure 10 Be fluxes to the sediment during these excursions to assess changes in the production of cosmogenic nuclides. This will aid in correlating climate records from ODP cores with those in terrestrial records such as ice cores.
