Productivity and Upwelling Data

Figure 2. Productivity and upwelling data from TN062-O550 and nearby ODP site 1019. The dashed red line indicates the onset of modern California coastal upwelling at ~2900 cal yrs BP, with the width of the light rectangle scaled to represent the 95% age confidence level (2720-3060 cal yrs BP).
