However, the uncertainties in
the geological sea level record are substantial, associated with sparse sampling, uncertainties in the proxy methods and uncertainties in the analysis methods.

During Expedition 359, Eberli's team drilled seven holes along the Maldives Archipelago to collect sediments that hold
records of past
sea level and environmental changes during the Neogene, a
geological time period that began 23 million years ago.
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 -

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.
According to

However, this hypothesis currently has three complications: underestimation of continental water storage and its confusion with minor lake and river water volume with respect to
