Apparently 2+ kilometers of ice for 30,000 years did not necessarily depress
the seafloor, but rather the continental mass, and it is still rebounding.
Sea levels are a result of a balancing act between more liquid water in the
sea and glacial rebound of the land. The first URL below takes you to a
treatment of the Irish and Celtic Seas and surrounding land masses with
respect to the last glaciation. There is a graphic of where a land bridge
between England and Ireland would most likely would have existed.
