Figure 4

Fine scale depth correction for mapping DSS to DE08 ice cores. The effect of correction for vertical strain rate can be seen, with no vertical strain rate correction (grey line) and vertical strain rates of \(6.57\times 10^{-4}\) year\(^{-1}\) and \(1.221\times 10^{-3}\) year\(^{-1}\) for DSS and DE08 respectively (black line). Notice the greatly reduced scale of the depth correction when vertical strain rate corrections are applied.
