Lake A Comparison with Regional Climate Records

Comparison of regional climate records including (a) Upper Soper Lake, Baffin Island, reconstructed June mean temperature (Hughen et al. 2000), (b) Tuborg Lake varve thickness standardized to the 1901-1961 mean (Overpeck et al. 1997) (c) Agassiz Ice Cap percent melt record (core A84; Fisher and Koerner 1994; Fisher et al. 1995), (d) Lake C3 varve thickness standardized to the 1901-1961 mean (Lasca 1997), (e) unfiltered Lake C2 varve thickness (Lamoureux and Bradley 1996) and (h) the Lake A pellet mean frequency record. Mean values the data sets are denoted by dashed lines. Data for all locations, except Lake A (this study) and Lake C2 (Lamoureux and Bradley 1996), was obtained from the IGBP PAGES/World Data Center for Paleoclimatology, NOAA/NGDC Paleoclimatology Program (http://www.ncdc.noaa.gov/paleo/data.html)
