Welcome to the first of its kind, the Geotandem 01! A collaborative series between EGU divisions. Interdisciplinarity is intrinsic to Geosciences, so we want to showcase how researchers approach the same topics from different but also complementing perspectives. In each edition, we will bring you a high-interest topic for the community seen from the eyes of diverse disciplines. Today, the Tectonic ...[Read More]

Think of a geodesist. What names come up in you? What do they look like? Do they have glasses? Is their hair short or long, grey or blonde? What’s their country of origin? Can you imagine them wearing a dress? And how come so many of them run marathons? I’m joking, but hopefully you get the picture. Geodesists, especially the ones in power positions, are not the most diverse bunch of people. Since ...[Read More]

The Gravity Recovery and Climate Experiment (GRACE) satellite mission (2002-2017) consisted of two satellites at ~500 km altitude separated by 200 km, following each other in the same orbit. The distance between the two GRACE satellites changes because of the gravitational pull of the masses beneath the satellites. As such, mass changes at or near the Earth’s surface caused variations in the dista ...[Read More]
