Holger Steffen

Holger Steffen is a researcher in geodesy at Lantmäteriet (The Swedish Mapping, Cadastral and Land Registration Authority). His primary research interests are related to glacial isostatic adjustment, from geodetic and geologic observations to the modelling of the displacement/velocity and stress fields. He is also involved in the estimation of a European strain rate model as part of EPOS (the European Plate Observing System) and is chairing the working group on "Geodynamics and Earth Observation" in the Nordic Geodetic Commission (NKG).

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]

Reshaping Earth: GIA and its far-reaching effects
Julien Seguinot (distributed via imaggeo.egu.eu)

As the Geodesy blog team (we are growing, horaay!), we wanted to create a space for researchers to talk about their work/papers in a more simplified language. For the first post in this series, we said “Wouldn’t it be cool if we learn more about Glacial Isostatic Adjustment (GIA) models?” then we realised that we first need to uncover what GIA is. So, we passed the pen to Holger, Rebekka and Yuche ...[Read More]
