for the project Untangling fast Earth's magnetic field variations with modeling the Levant geomagnetic field
The internal magnetic field of Earth exhibits spatial and temporal variations that are observed indirectly over geological timescales via remanent magnetization in rocks, archeological artefacts and sediments, directly over the past centuries by observatories and nowadays measured by satellites. While the present-day geomagnetic field is characterized by anomalous low in field intensity in the Southern Hemisphere, the past geomagnetic field variations reveal periods of anomalous high intensity – one well known event is the Levantine Iron Age Anomaly, which happened in the Levant region. Furthermore, the data from the same region show extreme variations with the field intensity increasing and decreasing very rapidly. Based on a recent catalog of archeomagnetic data and a new sediment record from the Dead Sea, the first geomagnetic field model for the Levant region spanning the past 4000 years, with high spatial and temporal resolution, will be built in order to understand the processes at the core-mantle boundary responsible for these extreme variations.
