Paleoshorelines are a useful tool to constrain the magnitude and mechanisms of this uplift, as they are often spectacularly preserved as wave - cut platforms, benches and sea - notches, providing a geological record of the interplay between sea - level changes and rock uplift.
Some studies have attempted to estimate the statistical relationship between temperature and global sea level seen in the period for which tide gauge records exist (the last 2 - 3 centuries) and then, using geological reconstructions of past temperature changes, extrapolate backward («hindcast») past sea - level changes.

Dr. Robert Dill, who obtained samples at relatively shallow depths (90160 FSW) as Chief Geologist on Cousteau's 1970 expedition to the Blue Hole, had waited 27 years to make this return trip to get additional data to answer questions on the geological record concerning average sea levels.
Hansen's paper last summer looked at 3 time scales — 10s, 100s, and 1000s of years — for the scary sea level rises and decided that millennial was out: the geological record showed that if the seas were to rise, they'd rise pretty fast.
