Application of Glacial Isostatic Adjustment Models at the Edge of the Fennoscandian Ice Sheet

We present and validate curves of relative and absolute sea level (RSL, ASL) obtained from Glacial Isostatic Adjustment (GIA) models for selected locations in Estonia over the last 11 000 years (11 kyr). The present day absolute uplift in the area is 2-4 mm/yr and the RSL curves were close to linear between ~1850 and 7 kyr BP. Comparison of GIA models with different proxies yielded slightly varying results depending on location; Global Navigation Satellite Systems (GNSS), geochronological proxies and the latest land uplift (LU) models fit well, while the use of tide gauge based RSL data is problematic in the Baltic Sea.
