A new study published today in the EGU journal The Cryosphere could improve our understanding of changes in the atmosphere–ice–ocean system and the mass balance of sea ice in a changing Arctic.
The European Geosciences Union is honouring 47 people at all stages of their careers who have made substantial contributions to the Earth, planetary, and space sciences.
This November EGU co-hosted an event to discuss how the geosciences can support the EU’s biodiversity targets, addressing specific issues relating to the Nature Restoration Law. Attended by several Members of the European Parliament and other key stakeholders, EGU’s Policy Manager Chloe Hill provides a reflection.
Applications are now open for individuals with an EU or Swiss passport, who are fluent in English, to work as a conference assistant at EGU23, in Vienna, Austria for our conference organiser Copernicus. Applications will be reviewed from 16 January 2023.
The EGU Outreach Committee has named three Public Engagement Grant winners this year: a project empowering school children to create their own environmental change maps, a model to explain how geophysics is done under the ocean and an investigative geoscience podcast !
To determine the best strategies for geoscience communication on TikTok, we created a TikTok account called “Terra Explore”. We produced 48 educational geoscience videos and evaluated each video’s performance. Our most-viewed videos received nearly all of their views from TikTok’s algorithmic recommendation feed, and the videos that received the most views were related to a recent newsworthy event (e.g., earthquake) or explained the geology of a recognizable area.
This high-resolution model-based study investigates the variability in the generation, propagation, and sea height signature (SSH) of the internal tide off the Amazon shelf during two contrasted seasons. ITs propagate further north during the season characterized by weak currents and mesoscale eddies and a shallow and strong pycnocline. IT imprints on SSH dominate those of the geostrophic motion for horizontal scales below 200 km; moreover, the SSH is mainly incoherent below 70 km.
We present a global fire emission model based on the GFED model framework with a spatial resolution of 500 m. The higher resolution allowed for a more detailed representation of spatial heterogeneity in fuels and emissions. Specific modules were developed to model, for example, emissions from fire-related forest loss and belowground burning. Results from the 500 m model were compared to GFED4s, showing that global emissions were relatively similar but that spatial differences were substantial.
Hi Martin. Thank you for joining me for this interview! To start, could you please tell our readers a bit about yourself and your research interests? I’m a space plasma physicist at Imperial College London, studying how the interaction between the solar wind and our magnetosphere leads to a huge amount of dynamics and waves that play a role in space weather. I’m also the Chair of EGU’s Outreach Committee and have been very active in outreach, media, and public …
We are getting used to perceiving glaciers more and more distant and disconnected from our mountains. With each passing year, it is more difficult to observe them, reach them or climb them. They are becoming an exotic element of the Alpine imagination. When our gaze rests on a mountain glacier, with its crevasses and large moraines, we are filled with the wonder of someone observing a new natural wonder. Facing an Arctic ice cap In the Arctic, it is not …
The upper atmosphere of Earth is constantly being impacted by the flow of charged particles being released from the sun. This flow (the solar wind) carries with it a magnetic field which distorts and reshapes that of Earth, ultimately resulting in a large amount of electromagnetic space weather energy being channelled into the polar regions. One of the most frequently observed outcomes of this process is the Dungey cycle [Dungey, 1961], which is where the bulk ionised population of upper …
