ABSTRACT.
Discusses the planned strategy for comparing the dating of the GRIP and GISP2 ice cores. Timescales dated independently by the two groups by annual layer counting agree within 250 yrs to the start of the Bolling at 14.5 kyr. By 40 kyr, the difference has widened to nearly 5 kyr. This is mainly because both timescales are preliminary at this stage. It is planned to produce a joint paper on the dating at a later stage.
