Snow Accumulation at “Byrd” Station, Antarctica

Abstract

AbstractThe rate of snow accumulation at “Byrd” station, Antarctica, was measured by various methods. Surface measurements yield a mean accumulation of 117 kg m−2year−1for the time interval 1962–70, within a 10 m radius of the station. The distribution of fission products with depth indicates a rate of 67 ± 4 kg m−2year−1for the period 1955–68 and of 100 ± 10 kg m−2year−1for the period 1965–68. The210Pb method yields a 60 year average of 110 ± 10 kg m−2year−1.
