Inferring the relationship between core-mantle heat flux and seismic tomography from mantle convection simulations
The heat flux pattern at Earth's core-mantle boundary (CMB) imposes a heterogeneous
boundary condition on core dynamics that may profoundly affect the geodynamo. Owing to …

New archeomagnetic directional records from Iron Age southern Africa (ca. 425–1550 CE) and implications for the South Atlantic Anomaly
Abstract The paucity of Southern Hemisphere archeomagnetic data limits the resolution of
paleosecular variation models. At the same time, important changes in the modern and …
