Late Holocene sea temperatures along the central California coast

Description :
Mussel shells from central California coastal archaeological sites record changes in sea surface temperature in the past 2000 years. The interval of variable sea temperatures 700-500 yr ago partially coincided with an interval of drought throughout central California. The continued use of local fisheries suggests that changes in settlement and diet were influenced more by drought than by a decrease in marine productivity, as fish provided a staple during an interval of low terrestrial productivity.
