This is early days for subsea archaeology of the continental shelf generally and the Dogger Bank in particular. What we truly do not understand yet is just how fast everything was inundated. The presently accepted line line for the relatively shallow Dogger Bank is around 8599BC through 6500 BC.
Fast matters because it allows limited erosion of local hills and stonework. It also allows rapid innundation to overwelm an uneroded area as well. This matters if you hope to have windows of original terrain. In short i do not prefer gradual but that is likely true for most phases. All this will matterv as the Bank is explored and sampled.
It may be possible to lock up a chronology of the rising sea level.
It is remarkable how the tradition of a rising ocean is particularly rich in the British isles..
