Geodesists on Tour: GPS measurements on Antarctica

Geodesists on Tour: GPS measurements on Antarctica

  Stories from the field – how exactly are those GPS data collected? The geodesy community at large benefits from the many science projects with open data policies.  A user simply has to navigate to a data portal, download the data, and within a matter of moments a world of possibilities opens up for potential research.  But where exactly do these data come from?  While scientific results get ...[Read More]

Geodesists on Tour: Gravity measurements on Antarctica

Geodesists on Tour: Gravity measurements on Antarctica

  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]

Notes from a hybrid conference

Zhen Li during his talk

With the COVID pandemic still ongoing, many conferences have been taking place online or have opted for a hybrid format, with combined on-site and online program parts. To many of us this still a rather new experience, so we decided to share some of the impressions we gathered in the hybrid meetings we attended so far. At the beginning of July, the International Association of Geodesy (IAG) Scient ...[Read More]
