Radiostratigraphy and Age Structure of the Greenland Ice Sheet, Version 1

This data set contains the traced deep radiostratigraphy of the Greenland Ice Sheet from airborne deep ice-penetrating radar data collected by The University of Kansas Improved Coherent Radar Depth Sounder (ICORDS), Advanced Coherent Radar Depth Sounder (ACORDS), Multi-Channel Radar Depth Sounder (MCRDS), and Multichannel Coherent Radar Depth Sounder (MCoRDS) instruments between 1993 and 2013. This is an IceBridge-related data set.

This is the most recent version of these data.
