Moving Ice and Satellites: The Motion of Crevasses in Antarctica

Amelia Carolina Sparavigna

International Journal of Sciences, 2019, vol. 8, issue 02, 130-139

Abstract: Antarctica is a remote and hostile continent, the study of which is fundamental because of the role it has on oceans and Earth’s climate. Affected by the global warming phenomenon, Antarctica requires a constant monitoring of the status and motion of its ice. This monitoring can be achieved by means of satellites. Here we will show, by using Google Earth imagery, some evidence of the ice flows in this continent. In particular, we will discuss the motion of some surface features of the ice shelves, which can be considered as the surface expression of basal crevasses. We can measure the rate of their motion too.
