From what I've read, sea levels rose about 400 ft. The melting has been ongoing over the last 20k or so years with the most significant melt events occurring at times now known as "melt water pulses". 3 such events that were the most significant are known as melt water pulse 1A, 1B & 2B. Many of the world's flood myths may have been inspired by these melt water pulses.
For example, the legend of Plato's Atlantis sinking into the sea as he dates it seems to occur with the ending of the Younger Dryas (temperatures rose 18 degrees friend in a single decade per the NOAA article linked) that puts our planet into the Holocene epoch in which we live today and seems to be a reprieve from the standard earth climate of glacial cold. This graph taken from the Antarctic Ice Core drilling known as Vostok which show temperature, CO2 and dust proxies found in the ice dating back nearly 500 YBP (year before present) shows the typical climate over the last 500k years to be much colder than we enjoy right now. What is still puzzling is the warming spikes every 100k or so years coupled with CO2 rise followed by a significant drop and what appears to be a return to the more normal colder climate. We still don't know what causes either one (spike up or spike down) to occur but by all accounts, seems to me we should be far more worried about a temperature drop and a return to a more normal but vastly colder climate. There is historical precedence for that to occur per the Vostok ice core samples.
As to sea levels, our epoch period of the last 15k years is noted for significant sea level rise (as noted at the NASA link above) and could account for the Atlantis flood story among others. Some speculate the biblical Garden of Eden was based on an earlier account and location at the head of the Persian Gulf where the Tigris and Euphrates Rivers now enter the gulf. Space imagery show ancient river deltas, one going west into Saudi Arabia and the other east into Iran which could account for the Pison and Gihon rivers in the biblical Eden story. This is barely even a hypothesis so don't be tempted to run with it just yet. A 400 ft. sea level drop would all but make the Persian Gulf disappear and leaving an ancient land mass of idyllic conditions. This area is also the area of ancient Sumer and considering the significance of the Sumerian flood myth to the re-telling in the Noah flood myth of the later Israelites, one can't help but be fascinated by the possibilities here, unproven that they are.
Another claimed lost continent is Lemuria in the Indian/Pacific oceans and looking at the proposed ancient map below demonstrating what a drop of 400 ft in sea level would look like land mass wise, such a legend could have come from earlier stories and human knowledge. Although in the case of Lemuria and Atlantis, 20th century man have taken them to a whole other level of myth and unprovable claims.
Several years ago, a research team in the Black Sea discovered an ancient shoreline about 180 ft. below the surface and some argue the next great archeology finds are not on dry land but in 200 to 300 ft deep sea water. Interesting thought for sure.
