  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]

Groundwater is one of the most important resources of freshwater for ecosystems and mankind. Because of this fundamental role in the Earth’s water and energy cycles, groundwater has been declared as an essential climate variable by GCOS, the Global Climate Observing System. As with other subsurface processes, it is difficult to observe and monitor on a global scale. This is especially true if you ...[Read More]

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]

Insights from the past ECS Representative of the Geodesy division

For our last interview we haven’t talked to a member of the current Geodesy division team. Instead we asked the past ECS (Early Career Scientist) representative of the Geodesy division, Katrin Bentel, a few questions. Fortunately, she gave us some insights about the role of an ECS Representative. Find out below.   What did you like most about your time as the Geodesy ECS Representative? ...[Read More]
