The decrease in14C/12C with depth in a varved sediment core raised from the eastern flank of Carmen Basin, Gulf of California, is greater than expected from varve and210Pb chronology. The discrepancy is ascribed to a virtually monotonic decrease in upwelling intensity from several hundred years ago to the present. This radiochemical study presents an approach, independent of previously used biostratigraphic techniques, for evaluating temporal variations in upwelling intensity in the Gulf of California.
