In particular, it aimed for a better understanding of the factors affecting snowpack compaction rates, by accurate measurement of compaction over a period of several years.

At four sites on the Antarctic Peninsula during the 2004-2005 austral summer ice cores were drilled to reveal the history of snowfall, and how the snow gets denser as it is crushed. Loggers designed to measure the compaction of snow were installed in boreholes, these sensors took a measurement every hour and are sensitive to downward movements of less than a millimetre. Automatic weather stations, sonic snow rangers and thermistor strings were also installed at each site, measuring the snow arriving at hourly intervals.
