Abstract : Snow and ice cores from two deep drill holes in Antarctica were studied to determine past records of snow accumulation and density variations with depth in the Antarctic ice sheet. Data on the variation of porosity and ice load with depth were also obtained. Byrd Station, located on the inland ice of West Antarctica, was the site of the first drill hole, which reached a depth of 309 m in ice estimated to be about 2500 m thick. Detailed analysis of the core stratigraphy to 88.6 m depth showed that the snow has been accumulating at an average rate of 15.6 g cm sq cm. annually since 1549 AD. (Author)
