Version Summary
Version Summary
-Added data from six airborne campaigns (2014–2019)
-Improved quality control and accelerated reflection tracing and matching by including an automatic test for stratigraphic conformability, a thickness-normalized reprojection for radargrams, and automatic inter-segment reflection matching
-Reviewed and augmented the 1993–2013 radiostratigraphy and applied an existing independently developed method for predicting radiostratigraphy to the previously untraced campaigns (2014–2019) to accelerate their semi-automatic tracing
