Eustatic Sea Level Change
Worldwide alterations in ocean surface level resulting from changes in the total volume of water in ocean basins or changes in basin volume due to plate tectonics.
Real World
During the Last Glacial Maximum (~20,000 years ago), the English Channel did not exist — Britain was connected to mainland Europe by a land bridge called Doggerland, which flooded as eustatic sea levels rose by over 120 metres after deglaciation.
