The Movement and Expected Lifetime of the Casey Ice Runway

The Australian Antarctic Division developed an ice runway near the Casey base in 2003 and its long-term viability is currently being explored. As opposed to a conventional runway, a runway on glacial ice is constantly moving and deforming, hence knowledge of this movement is paramount to comprehending the long-term viability of the runway. The movement of the Casey runway was estimated through an examination of regional measured and modelled data, and then two years worth of GPS measurements were assessed to provide an indication of the actual runway movement. The position of the runway was then forecast incrementally out to the year 2050. Although the runway is moving to the South West at almost 12 metres per year, and also experiencing rotation, compression, and a change in elevation, it is not expected that this movement will significantly compromise runway operations. With adequate maintenance of the constructed snow pavement, and appropriate management techniques, it is expected that the runway at Casey could remain operationally viable for many years into the future.
