Parameter keywords describe what was measured in this data set. Additional summary information can be found in the abstracts of papers listed in the data set citations. STUDY NOTES: This file shows ages and depths and average accumulation rates related to significant climatic changes over the past 60 ka in the GRIP ice core. The ages and the names of climate intervals are based on stratigraphy (Hammer et al., 1997), rather than the flow-model of Johnsen et al. (1997). REFERENCES: Hammer, C.U., K.K. Andersen, H.B.
