Abstract
  • The Holocene portion of the Siple Dome (Antarctica) ice core was dated by interpreting the electrical, visual and chemical properties of the were interpreted manually and with a computer algorithm.The algorithm was adjusted to be consistent with atmospheric methane stratigraphic (Greenland Ice Sheet Project 2) ice core, ¹⁰Be stratigraphic ties to the ¹⁴C record and the dated volcanic stratigraphy.The interpretation is more consistent and better quantified than the tedious and subjective manual interpretation.
