It will be a moving feast, of course. And all mapped land elevations and sea/coastal channel depths will have to be adjusted, the former decreased and the latter increased.

By the way, did you know that Cornwall (where Newlyn is located and where mean sea level is calculated) experiences a phenomenon where the land rises and falls by about 10-15 cm twice a day due to the effects of the tides and the weight thereof?
