Low resolution stable isotopes of ice core Taylor Dome

The delta 18O values were determined at the Quaternary Isotope Laboratory (M. Stuiver, Box 351360, University of Washington, Seattle WA 98195, USA). The time scale (st9507) was estimated from a correlation of delta 18O with the Vostok delta D record (Grootes et al. 1994; Steig, 1996). Between 0-340m the samples measured were of 1m cuts taken in the field. Each 1m core section was slabbed to provide a surface for ECM measurement; a thin slice was removed uniformly along the length for isotope analysis. From 340m to the bottom, sampling was done at the National Ice Core Lab at 0.5m lengths. Note that these core sections were shipped intact to NICL; they were not processed in the field.
