The depth-age scale was obtained with the use of various independent techniques to count annual layers in the core. An annual record of surface accumulation during the Holocene was obtained by correcting the observed layer thicknesses for flow-thinning. Fluctuations in accumulation provide a continuous and detailed record of climate variability over central Greenland during the Holocene. Climate events, including "Little Ice Age" type events, are examined. STUDY NOTES: The Meese/Sowers timescale is the official timescale for the GISP2 ice core, up to and including many of the publications in the 1997 GRIP/GISP2 compendium volume of the Journal of Geophysical Research. This timescale was created by combining the original layer-counted timescale of Meese and others (1994), to about 50,000 years, with a timescale constructed using trace gas measurements from the Vostok and GISP2 cores, placed on the SPECMAP marine timescale.
