Summary

The majority of studies of long-term sea-level change have concentrated on the trend in mean sea-level which is just one constituent of the trend in extreme sea-level. By fitting a spatial model to sea-level annual maxima from 62 UK sites, extreme sea-level trend estimates are obtained for the entire British coastline. These estimates exhibit smooth, but significant, spatial variation which arises from a combination of eustatic extreme sea-level change and local vertical land movements. Once the latter effect is removed, eustatic extreme sea-level trends are found to have no significant spatial variation and to be similar in value to trends in UK eustatic mean sea-level.
