Resumen:
The necessity for high resolution sea?]level reconstructions has increased with the
realization that the rate of sea?]level rise is accelerating. Presently, uncertainty concerning
the input and influence of glaciers and ice sheets causes these changes and future
projections in sea?]level to be highly debatable. In order to create more precise future
projections regarding sea level, it is vital to understand the spatial and temporal
characteristics of past sea?]level changes and their driving mechanisms. Therefore, precise
paleo sea?]level records are a necessary geologic benchmark by which to gauge future
change. Due, in part, to isostatic deformation and gravitational and rotational changes
driven by the exchange of mass between oceans and ice sheets, sea?]level changes are not
globally uniform and hence regional?]to?]local specific reconstructions are necessary. Such
records already exist for the Northern Hemisphere, most abundantly distributed along
the landmasses bordering the North Atlantic Ocean, but are distinctly lacking or at
inadequate resolution in the Southern Hemisphere, in particular along the South Atlantic
Ocean. Here we establish whether the relationship between modern foraminifera and
the tidal regime which is used to predict the elevation of fossil foraminifera from cores, a
tool often used in the Northern Hemisphere, is suitable for reconstructing past sea level
at a test site in Central Argentina.?]level reconstructions has increased with the
