Palaeogeography—Coastline Change

The RSL, surfaces have to be determined by spatial interpolation of data from shoreline displacement curves (rsl e RSL,) reconstructed from sedimentary records at sites r, e Rto grid points covering the area of investigation. The locations of the rsl curves are shown in Fig. 14.5, and for site references see Table 14.2. 

According to Equation 14.2, the interpolated RSL surfaces are systematically subtracted from the modern DEM (Meyer and Harff, 2005). A ten-year time interval resulted in 800 palaeo DEMs and palaeocoastlines. Eigure. 14.6 shows the distribution of the Baltic for the time slices t = 8000, t = 7500, t = 6200, t = 300. The time steps have been selected through an analysis of the rsl curves, whereby 6200 and 3000 year BP stand for points of shifts in the acceleration of sea-level change (Rosentau et al., 2007). 

The areas of regression in the northern Baltic can be clearly separated from those of transgression in the south by comparison of the scenarios shown by Pig. 14.6. Por the latter one, the scenario at 8000 year BP is shown in higher resolution in Pig. 14.7. These
