Spatial variation in extreme water levels in the Baltic Sea – North Sea transition from tide gauge records

Extreme water levels in the Danish waters, Figure 1, are governed by a variety of factors that provide a complex picture between locations, Figure 2 & Table 1, and where extremes may manifest themselves very differently between neighbouring locations and between water compartments during individual events.Knowledge about extremes is essential for climate adaptation, design, and planning purposes. In an ongoing research project we seek to develop more robust and objective statistics for Denmark. This includes a revisit to all tide gauge stations’ (TG) data and exploring methods for extreme value analysis (EVA).Below we provide four cases from Danish TGs to address some issues and questions regarding our work.Any feedback is much appreciated!
