Geodesists on Tour: Taking Greta Gravimeter to the North

Geodesists on Tour: Taking Greta Gravimeter to the North

Summer is coming to an end in the northern hemisphere, and it usually signals the end of the field season – at least in northern Europe. During the field season, we mostly take our absolute gravimeter (we call her Greta) to measure gravity at various locations across Sweden. Occasionally, we even take Greta to other countries – but that’s a story for another time.   Who is G ...[Read More]

Dual use of gravity data

Dual use of gravity data

Today, we are going to talk a little bit about dual-use, particularly in the context of geodesy. If you’re unfamiliar with the term, dual-use refers to the application of knowledge, information, data, products, or technology in ways that may deviate from their original scientific intent, often leading to ethical challenges. These challenges arise from the lack of control over who uses the da ...[Read More]

Geotandem: Exploring the subsurface of Mars using geodetic data

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 Tectonic ...[Read More]

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

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 dista ...[Read More]
