Replication of results is fundamental to experimental science, and replication of key findings in ice core science should be no less a requirement. The current practice of taking a single deep ice core from a given region makes replication and verification of the validity and spatial representativeness of key results difficult, and leaves the record vulnerable to missing intervals of ice (due to drilling problems, for example). The GISP2-GRIP experience highlights how important it is to have two cores in validating the stratigraphic integrity of the records. Furthermore, scientific demand for ice samples has been and will continue to be very unevenly distributed, with the ice core archive being completely depleted in depth intervals of high scientific interest (abrupt climate changes, volcanic sulfate horizons, meteor impact horizons, for example). In other intervals, however, nearly 90% of the ice remains, and space for storage at the National Ice Core Laboratory is becoming increasingly scarce. The lack of sample in key horizons hampers development and application of new techniques, and discourages entry of young investigators to the field.
