Differences in radiocarbon age between shell and charcoal from a Holocene shellmound in Northern California

Auteur :
INGRAM, B.L.

Description :
The A. presents a new chronology for the West Berkeley shellmound, based on radiocarbon measurements of organic carbon (charcoal) and inorganic carbon (mollusk shells) collected from 15 stratigraphic intervals within the mound. In addition to providing a detailed chronology of the mound, the radiocarbon age differences between shell and charcoal pairs collected from the same stratigraphic level suggest secular changes in the radiocarbon reservoir age of surface water along the eastern Pacific Ocean at the entrance to San Francisco Bay.
