Based on dated reference horizons down to 1623 m an ice flow model has been developed. The model is used to reconstruct past accumulation rates from the sequences of detected annual layers in the upper 2321 m of the 3029 m deep GRIP ice core. Comparison of these past time accumulation rates with the corresponding δ 18O values show a strong correlation. This relationship can be used in a non steady state flow model, in which past accumulation rates, deduced from the continuous δ 18O record, are used to model a time scale. The hereby determined time scale and the modelled annual layers compare well with the observed data.
