Age model and delta deuterium of ice core Taylor Dome from 20 to 10 kyr

Two timescales are reported here. The original is as reported in Steig et al., Science 282 (1998). This was adjusted slightly to match the flow-model constrained st9810 timescale (Steig et al., Geografiska Annaler, 2000). The adjustment is well within the uncertainties of the timescale and is more the sake of convenience. In general, the st9810 timescale should be used.
