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]

  Way too early on a Saturday morning in late June 2023 I woke up and started my travel to a small airport in Akureyri, North-East Iceland. This is the location of an Icelandic charter company called Norlandair that we used for our airborne geophysical surveys and logistic operations in the Arctic. For a few months I had been preparing a survey to test a new quantum-based technology for airbo ...[Read More]

Geodetic Data and Products – Idea of a Central Access Point

  The services of the International Association of Geodesy (IAG) provide very important and valuable geodetic data, information, and data products that are increasingly relevant for Earth System research, including monitoring of global change phenomena and a wide range of diverse applications such as satellite navigation, surveying, mapping, engineering, geospatial information systems, and so ...[Read More]
