It stands to reason that the documented Ice Age did occur. So where did all that melted ice go when the planet warmed up. Did it happen gradually. I'd venture to say yes, however during the melting period places like the Mediterreanwere definitely under sea level. Then the blocking of the oceans were breached and the flooding began. There's scientific proof of than in Western America in areas of the Grand Canyon.
If you are interested in things like this, read Emanuel Velikovsky's ‘Ages in Chaos’.

As an addition Immanuel Velikovsky also wrote ‘Worlds in Collision’. These two books may give you insight to these recent discoveries.

“Ages in Chaos” is imho the best introduction into Immanuel Velikovsky’s works, but in this context, the better choice would not be AiC or WiC, but “Earth in Upheaval”.
