Objectif(s): To monitor elevation changes of ice caps as part of climatic change research; to determine the elevation change of the Penny Ice Cap over a 30 year period from 1962 to 1992;
Description du projet: In 1962 a long-term project to monitor the elevation change of the Penny Ice Cap, Baffin Island was initiated. The growth or shrinkage of an ice cap is an indicator of climate change. Change in elevation is measured by the change of the force of gravity at a particular point on the top of the ice cap. As the ice cap grows the force of gravity decreases because gravity decreases with altitude. Gravity is measured with gravity meters.
