| Description: | Special Report Abstract: Eighty-five ice samples taken from the Byrd Station, Antarctica, ice core were analyzed for Na+, K+, Ca2+ and Mg2+ concentrations by atomic absorption spectroscopy. From 168 to 1243 m of the portion of the ice core analyzed the mean Na+, K+, Ca2+ and Mg2+ concentrations were 21, 3, 2 and 3 µg/l respectively, increasing to 37, 5, 5, and 7 µg/l respectively from 1264 to 2090 m, then decreasing to 19, 4, 2, and 2 µg/l respectively from 2100 to 2153 m. The 1264 to 2090 m region represents snow accumulations deposited over the last 13,000 to 60,000 years, based on independent stable isotope analysis; this correlates roughly with the Wisconsin stage cold interval, 11,000-74,000 years before the present. |
