(a) Observed and 1000 quasi-Nye-modeled depth-age relationships for each of six deep ice cores recovered from the GrIS. Depth is normalized by the local ice thickness. (b) Distribution of relative differences between quasi-Nye-modeled and observed depth-age relationships (relative difference from core age). (c) Relationship between the relative age difference of the bounding reflections (age difference of bounding reflection pair divided by their mean age) and the relative difference from core age.
