Group: Summary

   This data set is part of the West Antarctic Ice Sheet Cores (WAISCORES) 
   project, an NSF-funded project to understand the influence of the West 
   Antarctic ice sheet on climate and sea level change. WAISCORES researchers 
   acquired and analyzed ice core samples from the Siple Dome, in the Siple Coast 
   region, West Antarctica. This data set includes a timescale record for the 
   Siple Dome ice core.  This chronology is derived by measuring the delta 
   oxygen-18 of paleoatmospheric oxygen (δ18Oatm) 
   then correlating those measurements to the Greenland Ice Sheet Project 2 
   (GISP2) record by adjusting the Siple Dome timescale so that its curve of 
   δ18Oatm coincided with that of GISP2. The 
   replicate samples were measured at 1 to 1.5 kiloyear (kyr) resolution for the 
   length of the core. Because of core relaxation and cracking at the surface 
   associated with gas loss and a small fractionation of O isotopes associated 
   with loss of O2, the δ18Oatm timescale 
   and accuracy of the constraints of the Siple Dome control depths are subject 
   to limited error. Data are available via FTP in Microsoft Excel (.xls) and 
   Word (.doc) file formats.
