Dataset Title GRIP GReenland Ice Core Project
Dataset Purpose In 1989 the very summit of the Greenland ice sheet was selected as the site for the next deep drilling in Greenland, and by the summer of 1992 a 3029 m deep ice core reaching all the way to bedrock had been retrieved using the ISTUK drill as part of the GRIP. In 1993 an American team reached bedrock 30 km west of the GRIP drill site as part of the GISP2 project. While both the Camp Century and DYE-3 ice cores contained only a few hundred of meters of glacial ice, the glacial sections comprised about half of the more than 3 km long GRIP and GISP2 ice cores. Combining this much-improved resolution with large advances in ice core analysis techniques, the Central Greenland ice cores advanced the knowledge about glacial climate enormously. However, comparisons of the two ice cores made it clear that although both cores provide excellent records of past climatic conditions some 105,000 years back in time, the stratigraphies of the bottom ~300 m of both cores are disturbed. The ice has been flowing over the uneven bedrock topography in the area which has resulted in folding of the layers older than 105,000 years. This means that the ice deposited during the Eemian warm period some 115,000 - 130,000 years ago is disturbed
Dataset Abstract GRIP is a multinational European research project, organized through the European Science Foundation. Funding came from 8 nations (Belgium, Denmark, France, Germany, Iceland, Italy, Switzerland, and United Kingdom), and from the EU.
Acquisition Methodology Measurements were conducted on the same samples in Copenhagen for d18O and in Saclay (France) for dD. The common age scale is established from GRIP layer counting and stratigraphic markers including volcanic horizons and
Quality The ice cores present a 55 cm resolution with a mean temporal resolution of around 4 years. The maximum relative error between GRIP and North GRIP age scale is estimated to be around 20 years

Caption GRIP temperatures compared with NorthGRIP
Description GRIP temperatures derived from a borehole temperature profile (solid line) [Dahl-Jensen et al., 1998]. (left) GRIP and (right) NorthGRIP (top) site and (bottom) source temperatures derived from GRIP and NorthGRIP δ18O and deuterium excess corrected for seawater δ18O. Shaded lines show an estimate of the uncertainties due to the tuning of the isotopic model and the analytical precision (Source: Masson-Delmotte et al., 2005, JGR).
