Abstract:
Glaciochemical and accumulation rate records developed from four ice cores in central West Antarctica are used to reconstruct former atmospheric circulation patterns in this region for the last 40 years with extended records (150-250 years) at two sites. The sites lie on a 200 km traverse from 82 degrees 22 minutes south, 119 degrees 17 minutes west to 81 degrees 22 minutes south, 107 degrees 17 minutes west, gaining elevation from 950 to 1930 m. The glaciochemical records represent the major ionic species present in Antarctic snow: sodium, potassium, magnesium, calcium, chloride, nitrate, and sulfate.
Access Constraints
Dr. Reusch would be interested in knowing how you intend to use these data sets in your research. Please send him an e-mail! You may also contact him with questions regarding this data. Please cite these sources appropriately if these data are used in your publications. The 40-year records were published in Reusch, D. B., P. A. Mayewski, S. I. Whitlow, I. I. Pittalwala and M. S. Twickler ... (1999). 'Spatial Variability of Climate and Past Atmospheric Circulation Patterns from Central West Antarctic Glaciochemistry.' Journal of Geophysical Research 104(D6): 5985-6001. The longer records were published in Reusch, D. B., Recent Climate in Central West Antarctica Using Ice Cores, M.S. thesis, University of New Hampshire, Durham, 1997.
