Geodesists on Tour: Gravity measurements on Antarctica

Absolute gravity station at Aboa station in Western Queen Maud Land.

Antarctica is well known for its large ice sheet, covering 98% of the continent. A large part of the ice sheet is losing mass leading to vertical and horizontal movements of the crust as well as changes of the gravitational attraction. To observe these changes in gravity with the highest accuracy, it is necessary to visit Antarctica and measure gravity on a regular basis. Since the late 198 ...[Read More]

Welcome to the blog of the Geodesy Division of the European Geosciences Union. The blog serves to keep you posted on current research, news from the division and interesting geodesy-related topics in general. It will also give room to feature young (early-career) scientists and their science. An enthusiastic team of (Early Career) Scientists (ECS) runs the blog. Are you interested in writing a blog entry or learning more about the ECS activities of the geodesy division? Please get in touch with the Editor-in-Chief, Rebekka Steffen, or the ECS Geodesy (G) Representative Öykü Koç and ECS G Co-Representative Marius Schlaak.
