- Abstract:
- Geomagnetic secular variation has been exceptionally low in the Pacific throughout the 400 years of historical record. Whether this is a temporary or more permanent feature has been the subject of paleomagnetic debate for 35 years. New theory shows how it could arise through suppression of convection in the core by anomalously hot lower mantle beneath the Pacific. This project will assemble a definitive dataset for secular variation from C14-dated Hawaiian lava flows and borehole data for the last 40 kyr in order to test the suppressed convection hypothesis by comparison with convection and dynamo calculations. Fieldwork will include a novel assessment of the influence of crustal magnetisation on paleomagnetic directions.
