Fig. 3

Annual sedimentation rates (cm³/(cm2*y)) over the study period. The significant changes include the vertical uncertainties, corresponding to a 95% confidence level. The red and blue lines illustrate the recent SLR (red) between 1993 and 200937 and the general mean sediment accumulation (blue) of the intertidal flats between 1998 and 2016 in the German Wadden Sea44.
