"...and gives significant hints on the sea levels then."

Uh, professor, we already know what sea levels were then with a fair degree of accuracy. Sea levels have been rising for the last 11,000 years at a fairly constant rate and have totaled about 800 feet over that time period.

That'd be "average sea level". More recently they've found that gravitational anomalies create mountains and valleys out there in the Ocean that we have been overlooking in our computations of the effect on shorelines.

I've been trying to think through what these things are like and what they are doing ~ first off they'd be detectible only from space, and at the same time they could cause some sea levels on some shores to drop.

They probably explain the biological anomaly discovered in Alaska a couple of decades back. The guy found the terminal forests were at a lower elevation than the immediate post Ice Age bogs along the rain forest area South of Juneau. The theory had been that the bogs came first, then the trees, but there the trees came first then the bogs.

The only way to explain it was for the sea level in that region to be dropping while it was rising further up the coast North of Juneau. However, there were no geological signs of subsidance.

The guys who have the job of understanding this currently put little store in sea level data having much relevance to anything ~ particularly no the predictions of cities being flooded suddenly while their citizens stand there dumbfounded and drown.

I wondered if this was really just attributable to erosion -- 5000 BC? Hmm...
