REKLIM - Reconstruction of Sea Level in the North Sea

Regional sea level changes are studied as part of Topic 2 'Sea level change and coastal protection' of the REKLIM project of the Helmholtz Association. The coastal area of the North Sea is densely populated and prone to inundation due to storm surges. Sea level trends in the North Sea differ from global ones for the last Decades. In cooperation with the Helmholtz Zentrum Geesthacht and the University of Concepción the yearly mean distribution of sea level in the North Sea is reconstructed from tide gauge and satellite altimeter data starting in 1900. Empirical orthogonal functions (EOF) estimated from Topex, Jason-1 and Jason-2 altimeter data from 1993 to 2012 were combined with historical data from 28 tide gauges from around the North Sea. The altimeter data were processed at GFZ (ADS Central), the tide gauge data originate from PSMSL.
