If antartica and greenland should melt, 230 feet is the conservative estimate for the amount of raise in ocean level can be expected. I have read 200 meters, though that must have been a typo.
Multiply those two figures and you get volume... divide it by the amount volume is reduced from ice to water... then get the square miles of ocean

While it is possible that the site could have been exposed 9,500 years ago it is not certain. But let's assume it was. Let's also assume there actually was a city on the site and the inhabitants had to move as sea levels gradually rose. Why is there no other evidence of even village life until 6,000 years later and 200 miles away? If a migration was forced by rising sea levels why would it take 6,000 years? Why would the gradual rise in sea level (a global average of something like 1cm/year) have caused them to disappear completely?

12. AN EXAMINATION OF THE PALEOINTENSITY RECORD AND GEOMAGNETIC EXCURSIONS RECORDED IN LEG 155 CORES
Stanley M. Cisowski and Frank R. Hall
ABSTRACT
The normalization of the natural remanent magnetism to laboratory-induced remanence for discrete samples from the top 54 m of Hole 932A produces a pattern similar to the apparent variation of the geomagnetic dipole intensity for the period 10-80 ka. Similar patterns in the shipboard archive-half intensity measurements for several other holes suggest that a paleointensity stratigraphy can be employed to date Leg 155 fan sediments. Two short intervals of anomalous field directions, or excursions of the geomagnetic field, have been identified in Hole 932A, at ages of ~32 ka and ~43 ka, as determined from their positions within the intensity pattern. The younger excursion, which has been identified in nine Leg 155 holes, is best defined by discrete samples from Hole 930B. This excursion, which may correspond to the Lake Mungo Excursion, as recorded in aboriginal firepits in Australia, and sediment cores from the Gulf of Mexico, is characterized by short-lived (~40 yr) synchronous peaks in inclination and intensity. The older Hole 932A excursion probably represents the Laschamp Excursion. Discrete sample analyses for Holes 942C and 946A revealed two other anomalous polarity intervals within interglacial Stage 5. The younger excursion is associated with an interglacial carbonate layer representing Substage 5c. The older interval includes several short periods during which the field was nearly reversed, and may represent the Blake polarity event within Substage 5e.

ok so y is it that all these ancient cities were on the coast? y isn't there other pre cataclysmic cities inland up rivers or other water ways? we haven't found one or have we? did the ancients only build megalithic cities by the coast?
