Basal Ice Unit Thickness Mapped by the NSF COLDEX MARFA Ice Penetrating Radar

This dataset contains the basal ice unit thickness as measured by the NSF COLDEX MARFA ice-penetrating radar survey, which mainly focuses on the southern flank of Dome A. The \"basal ice unit\" is hereby defined as the bottom portion of the ice sheet where no clear and traceable englacial reflection is detected by the radar sounder. Raw radar data can be found at: https://doi.org/10.15784/601768. The basal ice unit is mapped using the DecisionSpace Geosciences 10ep software package. This dataset provides three data products:
<br/>• Thickness of the basal ice unit
<br/>• Thickness of the stratigraphic ice unit above the basal ice unit
<br/>• The shape of the basal ice unit boundary, where rapid basal ice unit thinning is observed in the middle of the South Pole Basin.
