Outcrop analogues to Carbon Sequestration Targets: the Gog Quartzite of Alberta – including a short virtual field trip!

Jon Noad January 12, 2023

Introduction In 2022 I was asked to put together a virtual field trip looking at carbon sequestration (CCS). We are particularly lucky in Alberta in having three excellent Cambrian targets for CCS including the Basal Cambrian Sandstone, currently being used for CCS in Shell’s QUEST project, quartzites of the Deadwood Formation (being utilized for a CCS project in Saskatchewan) and the Gog Quartzit ...[Read More]

Arc and Intraplate Volcanism in Northeast Asia Since mid-Miocene: Numerical model studies

Changyeol Lee and edited by Giridas Maiti January 11, 2023

Northeast Asia may be one of the best natural laboratories to investigate both arc and intraplate volcanisms which have developed since the mid-Miocene. The arc volcanoes have occurred above the sinking young (Philippine) and old (Pacific) oceanic plates in Southwest and Northeast Japan subduction zones, respectively. The intraplate volcanoes across the Korean Peninsula and China have occurred abo ...[Read More]

Imaggeo On Monday: Blood moon over Germany

Simon Fuhrmann January 9, 2023

A blood moon occurs during a total lunar eclipse. The sunlight falling through the air layers of the Earth’s atmosphere is refracted inwards, whereby especially the short-wave blue components are weakened by scattering. The long-wave red components, on the other hand, still reach the moon, which leads to the red colouring. Photo by Simon Fuhrmann shared on imaggeo.egu.eu. Imagg ...[Read More]

Seismic Swarms in the Azores

EGU Guest blogger January 9, 2023

Will Sturgeon – Post-Doc at the Earth Sciences Department of University College London, UK – takes us on a journey to the Azores to deploy seismometers in response to the seismic swarm earlier in 2022… Protruding from the central Atlantic Ocean, about 1,400 km west of Lisbon, is an archipelago of nine volcanic islands, known as the Azores. Also described as “Europe’s Hawaii”, the ...[Read More]

What’s new at EGU23?

Sinikka Lennartz January 6, 2023

EGU23 is back with longer talks, posters and PICO sessions! While EGU is always great to catch up with colleagues in classical sessions offered every year, here, we want to highlight some new sessions that will premier at EGU23. We have selected a few from each Subdivision to show the broad range of topics covered. General Biogeosciences The PICO session “It’s all about migration!” focuses on migr ...[Read More]

GeoPolicy: What’s coming up for 2023?

Chloe Hill January 6, 2023

2022 was an exciting GeoPolicy year with many new science for policy projects and opportunities beginning and others being restored after a 2020/2021 pause due to COVID19. In 2023, we hope to build on EGU’s current initiatives and bring you yet more opportunities to engage and get involved in European policy! This blog post will kick-off the New Year by outlining a few of the key science for polic ...[Read More]

A touch of space weather! An EGU funded outreach project for blind and visually impaired students

Lenka Zychova January 4, 2023

This image shows four tactile images created to share space weather phenomena with blind and visually impaired learners. The image shows a representation of the magnetosphere (a small blue ball with black concentric circles surrounded by dots to the left and right, the ones on the left are smaller), aurora formation (a small blue ball with black concentric circles to the left and right with dots on the circles) and radiation belts ( a small blue ball with a yellow and brown pair of rings extended evenly to the left and the right). All the images are on a white background.

We can all probably agree that the Northern Lights are one of the world’s most spectacular natural displays. But how do we share this beauty with children who are blind? How do we explain the processes behind the aurora creation to the visually impaired when all the illustrations of Earth’s magnetosphere are in 2D? The Northern Lights are just one of the consequences of ‘space weather’. Space weat ...[Read More]

Can Artificial Intelligence replace scientists to explain Climate Change? Find it out in our first interview to… ChatGPT!

Davide Faranda January 3, 2023

Figure: DallE (the visual cousin of ChatGPT) has produced this image when I asked for “a cartoon showing a climatologist with research articles walking on a weather map” As a communication officer of the division of Nonlinear Processes I started to write posts for the EGU blog a few years ago and I found it a very difficult task: one has to find the right scientific sources about arguments ...[Read More]

Imaggeo On Monday: Aurora show on the road

Junbin Zhao January 2, 2023

In Sweden a beautiful Northern Lights show proceeds unnoticed by the busy drivers passing by. The Northern Lights or Aurora Borealis are spectacular lights created as a result of disturbances in the Earth’s magnetosphere caused by solar winds. They are visible at both polar regions and or often seen as veils or lines of greenish-blue light. Photo by Junbin Zhao shared on imaggeo.egu.eu. &nbs ...[Read More]

2022 Recap of the HS Blog

Editorial Team December 28, 2022

Thinking about the past year, one of the highs of the year was definitely seeing the EGU General Assembly back to Vienna in May. The first-ever fully hybrid EGU meeting was a great success with over 12,000 presentations. Most of all, it was great seeing our hydrological sciences community meeting in person again. Many constraints prevented us from having all the features we love in the GA meeting, ...[Read More]
