Traditionally geodesy is the science of the measurement and the mapping of the Earth’s surface. Since the surface is mainly shaped by the Earth’s gravity field the classical definition includes the Earth’s gravitational potential. Observing the Earth’s figure, the orientation and rotation as well as the gravity field, geodesy today provides spatial and temporal patterns of geophysical processes within the Earth system such as sea-level rise, tides, melting of continental ice masses, changes in global water circulation and in the atmosphere or deformations of the solid Earth. Consequently, the Geodesy Division covers activities on the whole spectrum of modern geodetic Earth system modelling from the measurement systems to the investigation of geophysical processes.

Bits and Bites of Geodesy – Satellite radar altimetry: How do we know that sea level is rising?

In a previous post, Thomas Frederikse briefly explained how geodesy is used to observe sea level change. In this part of Bits & Bites, Bene delves deeper into the topic. Rising sea levels are one of the consequences of climate change that already impacts people in low-lying coastal regions, and the future prospects are not exactly encouraging as well. We know that rising sea levels are caused by warmer water that expands in volume and by melting ice caps and …


Geotandem: Exploring the subsurface of Mars using geodetic data

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 Tectonics & Structural, Geodesy and Geodynamics divisions come together to present one of our favorite planets of the solar system, …


Expanding the picture: What does a geodesist look like?

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 the times of people like Carl Friedrich …


High resolution terrestrial water storage changes from combination of GRACE and models

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 distance between the two satellites over time. Following this basic concept, measuring inter-satellite distance by an ultra-precise microwave-based …

Current issue of the EGU newsletter

How do you get more people to care for the geosciences – a field that affects and influences all of life itself? Scientists across the EGU network share their stories!

Friedrich Barnikel outlines how, since 2003, EGU brings together scientists and teachers for capacity-building workshops, while Evi Nomikou takes us through EGU’s third Geoscience Day, highlighting volcanic geohazards to over 260 school students.

We also hear from Grace Skirrow who breaks down a seemingly complex subject like fluvial geomorphology and the role that it can play in policy decisions. Meanwhile, geologist Sinelethu Hashibi explains why she’s driven to translate geoscience for isiXhosa-speaking communities. And for those of you fond of card games, don’t miss the launch of QUARTETnary: a game about the geological time scale, developed by Iris van Zelst and Lucia Perez-Diaz and partly funded by the EGU Public Engagement Grant 2021.

Finally, don’t forget to visit our EGU24 page to stay up-to-date with information on the upcoming General Assembly this April. You can also subscribe to receive monthly updates in your inbox at the beginning of each month.
