Irregularities in Scandinavian postglacial uplift/subsidence in time scales tens, hundreds, thousands of years

Abstract

Discussions continue on uplift/subsidence in Denmark/southern Scandinavia. The patterns in time scales of 10s, 100s and 1000s of years show some similarities and some differences. Geodetic observations exist for all of Scandinavia. Those describe the phenomenon in 10–100s of years scale. Earthquake observations in seismology are of relevance to the same time scales. Geological studies of dated shore lines describe the postglacial earth-surface motion in a quite different time scale of 100–1000s of years. There is a need for integration of these observations geographically. Present integration of the data of various time scales is that the overall uplift pattern of all time scales 10s, 100s, 1000s and 10,000s years are coincident. But a few geodynamics irregularities are found. Further observations in the various time scales will be collected together with process descriptions of the observed similarities and differences in the DynaQlim project.
