Hu, F.S., Kaufman, D.S., Yoneji, S., Nelson, D.E., Shemesh, A., Huang, Y., Tian, J., Bond, G.C., Clegg, B.F., Brown, T. 2003. Cyclic Variation and Solar Forcing of Holocene Climate in the Alaskan Subarctic. Science, 301, 1890-1893.
High-resolution analyses of lake sediment from southwestern Alaska reveal cyclic variations in climate and ecosystems during the Holocene. These variations occurred with periodicities similar to those of solar activity and appear to be coherent with time series of the cosmogenic nuclides 14C and 10Be as well as North Atlantic drift ice. Our results imply that small variations in solar irradiance induced pronounced cyclic changes in northern high-latitude environments. They also provide evidence that centennial-scale shifts in the Holocene climate were similar between the subpolar regions of the North Atlantic and North Pacific, possibly because of Sun-ocean-climate linkages.
STUDY NOTES: Biogenic silica (BSi) data from Arolik Lake, southwestern Alaska. Presented are raw biogenic silica values plus detrended and smoothed BSi.
