On the estimation of regional and global sea level variations in the 20th century

Jens Schröter and Manfred Wenzel, AWI

Traditional attempts to determine past sea level variations (e.g. Church et al., Meyssignac et al.) use structure functions such as EOF’s to interpolate in space between sparse observations at tide gauge positions. Unknown expansion coefficients (PC’s) are then found by minimizing the difference between modelled and observed sea level.
Here we try alternate approaches for a more direct estimate of the PC’s.

Questions we would like to explore during the meeting include:

• How can we distinguish between different reconstructions?
• Is there independent observational evidence to verify or falsify our results?
