![]() Figure 4. Interpolation spline extended through all of the Cariaco Basin data set and compared to coral 14C-U/Th data from Tahiti, Barbados and New Guinea. PB, YD, B/A and light blue bars as in Figures 2 and 3. Cariaco Basin spline shows close agreement with German pine data from 10-12 cal kyr BP, and general agreement with coral data older than 12 cal kyr BP. Cariaco Basin data set resolves considerable detail that is not resolved by the coral data, including plateaus at 11.7 and 11.4 14C kyr BP, and century-scale structure imposed on a gradually-sloping plateau during the Younger Dryas. All 14C errors reported at 1s. |
