Description :
New radiocarbon dates provide ags for two submerged strandline features of the Massachusetts inner shelf. These ags provide limited control on a relative sea-level (RSL) curve for the late Wisconsinan and Holocene. Rapid changes of RSL around 12,000 yr ago may be related to changes in global glacial meltwater discharge and eustatic sea-level change shown by dated corals off Barbados. Variations in the magnitude and timing of RSL change from south to north along the coast of the Western Gulf of Maine are due to greater crustal depression and later deglaciation to the north.
