Changes in Holocene sea level through time have been attributed to eustatic, isostatic, and neotectonic processes. Eustatic changes imply global expression through linkage in world climate, or changes in ocean water or basin volume, while isostatic adjustment and neotectonic distortion involve regional or local geophysical parameters which must be ascertained. A Holocene sea level curve is being developed for the southeastern United States through a study of marsh stratigraphy and archaeologic sites located in marsh and interriverine areas. The curve is evaluated in light of intensive investigations of regional and local tectonic elements. Both major and some minor trends in sea level change are shown to include significant eustatic components.
