Calculating postglacial sea-level change within few seconds: a statistical emulator for GIA

Yucheng Lin, Marius Schlaak and Bramha Dutt Vishwakarma December 22, 2023

Sea-level change serves as a direct indicator of climate change with profound implications for coastal areas. Since 1900, the global mean sea level (GMSL) has risen over 20 cm, leading to beach erosion, delta inundation, and increased flooding worldwide. Over glacial cycles spanning tens of thousands of years, interactions between ocean and continental-scale ice sheets can cause GMSL to fluctuate ...[Read More]

Reshaping Earth: GIA and its far-reaching effects

Holger Steffen, Rebekka Steffen, Yucheng Lin and edited by Öykü Koç December 19, 2023

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]

Geodesists on Tour: On a Campaign in the Arctic with a Giraf(f)e in the Aircraft

Tim Jensen and edited by Rebekka Steffen November 6, 2023

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 reference frames – Why do we need them?

Detlef Angermann, Laura Sánchez, Martin Sehnal and edited by Rebekka Steffen October 30, 2023

A geodetic reference frame provides the foundation for determining positions on Earth and in space, as well as for reliably quantifying our planet’s changes due to geodynamic processes and ongoing climate change. The ITRF ensures a uniform basis to tackle current and future challenges, including a wide range of location-based applications (navigation, traffic and fleet management, transport ...[Read More]

EGU Campfire Geodesy – Share Your Research – Seventh Edition

Öykü Koç October 27, 2023

We are finally back with the 7th edition of Geodesy Campfire – Share Your Research. The Geodesy EGU Campfire Events “Share Your Research” give (early career) researchers the chance to talk about their work. We have two exciting talks; the first is by Stacy Larochelle and the second is by Parisa Shafiei. Below you can find detailed descriptions of their talks. We will have time for networking ...[Read More]

Postdoc Diaries: Challenges of Postdoc Life

Öykü Koç, edited by Rebekka Steffen and Marius Schlaak September 21, 2023

Hello, it’s us again! Coming back from the holidays, there couldn’t be a more fitting way to kick off a new blog season than by delving into the world of postdocs or to put it more precisely, by stepping into the shoes of a postdoc. As we try to reacquaint ourselves with our daily routines, I think it’s a perfect moment to empathise with those navigating postdoctoral life’s uniqu ...[Read More]

Women in Geodesy: Kristel Chanard

Öykü Koç, Rebekka Steffen and Andreas Kvas May 29, 2023

I hope you are ready to be inspired because we have another exciting interview, with Kristel Chanard, our Outstanding Early Career Scientist Awardee of 2022. I promise that her answers will encourage you to pursue a career in science or continue to that! Her answers remind us again that we need to make geosciences more inclusive and diverse. So, let’s leave the spotlight to Kristel and hear what ...[Read More]

Women in Geodesy: Sara Bruni

Öykü Koç, Rebekka Steffen and Andreas Kvas May 22, 2023

Are you ready to hear from another woman in geodesy? We pass the mic to our Outstanding Early Career Scientist Awardee of 2018, someone who is currently carrying out her scientific works outside of academia. We are not going to take that much of your time and leave the stage to her. Would you like to share your thoughts about what being a woman in science means to you? I enjoy being a scientist be ...[Read More]

What would we like to see from future gravity missions? Help us to define the scientific requirements!

ESA's QSG4EMT Study Team, edited by Öykü Koç and Rebekka Steffen May 19, 2023

Are you interested in water storage, sea level, ice sheets, crust-mantle dynamics, or any other mass change signals? Please complete the following user requirement survey and help shape future satellite gravity missions Mass changes on and below the Earth’s surface, such as from water storage variations to groundwater use, glacier melt, sea level change, and earthquakes, among many others, c ...[Read More]

Women in Geodesy: Susanna Zerbini

Rebekka Steffen, Öykü Koç and Andreas Kvas May 15, 2023

In the past weeks and months, we have introduced you to famous female geodesists who won the Vening Meinesz medal of the EGU Geodesy division. This week we turn our eyes to Susanna Zerbini, who was awarded with the Vening Meinesz medal in 2009 for her important work at the interface of geodesy and geodynamics using space geodetic techniques. Having this in mind, we were curious to find out what sh ...[Read More]
