Description :
Analyses of sediment cores from two lakes in the central Brooks Range provide temperature and moisture balance information for the past 8500 cal yr at century-scale resolution. Two methods of oxygen isotope analysis are used to reconstruct past changes in the effective moisture (precipitation minus evaporation) and temperature. The analytical precision of the geochemical data and the chronology are of sufficient quality in these new sites to document Holocene climatic variability at millennial-to-centennial time scales.
