Melting ice sheets will have global impact on ocean tides

The new results show that sea level does not increase uniformly across the globe in response to melting of the polar ice sheets. In fact, sea level changes in response to ice loss are highly spatially variable, especially close to the retreating ice sheets. The new results, which are obtained with a numerical model of the global tides, show that the tidal changes due to ice sheet collapse and associated sea level changes will be highly variable and affect a number of different important processes. 

Along some coastlines the tidal range will be greatly amplified, for example the North Walian coastline, whilst along other coastlines such as South Wales, the tidal range will be reduced. Moreover many functions of the ocean will be altered by the changes in the tides.
