註釋Prehistoric archeological sites on the coastal plain of the Delmarva Peninsula are widespread and of varying ages. Many Late Quaternary geologic elements have impacted the archaeological deposits of the Middle Atlantic coastal plain. Eolian processes and marine transgression have largely been ignored by archaeologists as fundamental variables impacting anthropological interpretations of past lifeways. This study was undertaken in an effort to gain insight into the interrelationship between climatic change, geologic processes, and cultural responses. Five sites were selected to resolve the upland late Pleistocene eolian loess depositional sequence in western Delmarva. Three of these sites contained archaeological remains which provided a higher degree of resolution into the timing and duration of loess deposition. Ten drowned archaeological sites within the Chesapeake Bay and the Atlantic coastal bays were selected to better understand how varying rates of marine transgression impact archaeological deposits and the data from these sites were also used to assess published Holocene sea level curves. A cultural artifact and vertebrate skeletal material discovered on the Atlantic Coast outer continental shelf were also analyzed. The bathymetric depths of these finds were assessed to better understand rates of terminal Pleistocene sea level rise, as well as, isostatic changes along the Middle Atlantic Bight. In sum, the dissertation outlines many geoarchaeological variables unique to the Delmarva Peninsula that have blinded archaeologists who have attempted to reconstruct past lifeways solely on terrestrial surface archaeological deposits.
