Understanding Earth's core dynamics over millennial timescales requires models that jointly describe the evolution of the geomagnetic field and core surface flow, while accommodating the sparse, irregular, and uncertain nature of…

Glacial Isostatic Adjustment (GIA) caused by the melting of past ice sheets is still a major cause of sea-level variations and 3-D crustal deformation in the Mediterranean region. However, since the contribution of GIA cannot be separated…
