Past Accumulation Rates of the Western Antarctic Ice Sheet Near an Ice Divide
The study of accumulation rates of ice is a direct link to the evolution of ice sheet. It is believed by scientists that ice sheet evolution will aid in the mystery of climate change and may lead to predictions about climates in the future. This dissertation focuses on studying the accumulation rate...

The study of accumulation rates of ice is a direct link to the evolution of ice sheet. It is believed by scientists that ice sheet evolution will aid in the mystery of climate change and may lead to predictions about climates in the future. This dissertation focuses on studying the accumulation rates of ice within the Western Antarctic Ice Sheet near an ice divide. The site of study is located just near Subglacial Lake Ellsworth. Radio Echo Sounding (RES) data was collected to measure the depths of certain isochronous layers within the ice sheet and a one-dimensional (1D) compression model was used to determine the accumulation rates.
