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 !
In August 2018, the first wind lidar Aeolus was launched into space and has since then been providing data of the global wind field. The primary goal of Aeolus was the improvement of numerical weather prediction. To verify the quality of Aeolus wind data, DLR performed four airborne validation campaigns with two wind lidar systems. In this paper, we report on results from the two later campaigns, performed in Iceland and the tropics.
Atmospheric methane (CH4) has been growing steadily since 2007 for reasons that are not well understood. Here we determine sources of methane using a technique informed by atmospheric measurements of CH₄ and its isotopologue 13CH4. Measurements of 13CH4 provide for better separation of microbial, fossil, and fire sources of methane than CH4 measurements alone. Compared to previous assessments such as the Global Carbon Project, we find a larger microbial contribution to the post-2007 increase.
The morphology and size of sediments influence erosion efficiency, sediment transport and the quality of aquatic ecosystem. In turn, the spatial evolution of sediment size provides information on the past dynamics of erosion and sediment transport. We have developed a new software which semi-automatically identifies and measures sediments based on 3D point clouds. This software is fast and efficient, offering a new avenue to measure the geometrical properties of large numbers of sediment grains.
This imperfect cube of calcite was formed on the gold surface during the electrochemically assisted scaling process. Once negative electrochemical potential is applied to the gold surface, the oxygen dissolved in water undergoes reduction, yielding hydroxide anions. These anions accumulate at the gold-solution interface, forming a high pH layer. As calcite becomes less soluble with the increasing pH, it can precipitate on gold even from undersaturated solution. Like this wannabe cubic calcite crystal. Photo by Joanna Dziadkowiec shared on imaggeo.egu.eu. …
“Who are these men?!” he says, seeming genuinely baffled. I feel my shoulders rise towards my ears with tension as I wait for him to continue. The man is summarizing what his group, comprised solely of men, have arrived at during their group-discussion at the gender equality seminar we are taking. We have been presented with, I might say, “the usual” statistics for academic women. A prevalence, certainly, of sexual harassment and hostile working environments, but specifically highlighted also is …
In the early days of 2023, nearly 100 researchers gathered in Longyearbyen, Svalbard, one of the last permanently inhabited places before reaching the North Pole (see my previous blogpost about Svalbard). The Svalbard Integrated Arctic Earth Observing System (SIOS) held its fifth Polar Night Week. SIOS is an international partnership of research institutions that study the environment and climate in and around Svalbard. This annual meeting brings the SIOS community together for science seminars, working group meetings, dedicated keynote talks, …
