The EGU Education Committee has awarded four Higher Education teaching grants for 2021, to educators from Europe and the United States. Find out more about our deserving winners and their plans for Higher Education teaching projects.
Natural Hazards in the news: flooding in western Europe, meet the Natural Hazards Division ECS Rep Valeria Cigala, how the Olympics has more geology than you expect and submit your session proposal for EGU22.
From the 13th to the 15th July 2021, a period of intense rainfall led to catastrophic and deadly flooding in Western Europe. Several of EGU’s Division Presidents from natural hazards, hydrology, geomorphology and more, explain what happened and why interdisciplinary disasters like this are difficult to manage.
Newly announced journal metrics for EGU’s journals, managed by our publishing partner Copernicus, have revealed an increase in Impact Factor for all EGU Journals. Several journals, including Atmospheric Chemistry and Physics (ACP), Earth System Dynamics (ESD), Natural Hazards and Earth System Sciences (NHESS) and The Cryosphere (TC) have reached their highest value ever. See the full list of new details on Copernicus’ website.
Thanks to the enthusiastic efforts of our members and volunteers, vEGU21 reached an amazing 18,155 people over the two weeks of the virtual General Assembly!
This paper reports on dark current signal anomalies of the detectors used on board the ESA’s Earth Explorer satellite Aeolus during the first 1.5 years in orbit. After introducing sophisticated algorithms to classify dark current anomalies according to their characteristics, the impact of the different kinds of anomalies on wind measurements is discussed. In addition, mitigation approaches for the wind retrieval are presented and potential root causes are discussed.
Satellite images show that the Amazon forest has greened up during past droughts. Measurements of tree stem growth and leaf litterfall upscaled using machine-learning algorithms show that leaf flushing at the onset of a drought results in canopy rejuvenation and green-up during drought while simultaneously trees excessively shed older leaves and tree stem growth declines. Canopy green-up during drought therefore does not necessarily point to enhanced tree growth and improved forest health.
Plasma waves are an integral part of cometary physics, as they facilitate the transfer of energy and momentum. From intermediate to strong activity, nonlinear asymmetric plasma and magnetic field enhancements dominate the inner coma of 67P/CG. We present a statistical survey of these structures from December 2014 to June 2016, facilitated by Rosetta’s unprecedented long mission duration. Using a 1D MHD model, we show they can be described as a combination of nonlinear and dissipative effects.
Have you ever wondered what undertaking cryo-fieldwork in a glacial environment typically involves? Well, what about undertaking cryo-fieldwork in a glacial environment during a global pandemic?! Read on to find out all about the challenges I faced on my recent trip to Iceland in July 2021… Fieldwork Preparation As this previous blog post highlights, undertaking cryo-fieldwork requires a significant amount of preparation and stringent planning to ensure it will run smoothly. During a global pandemic, however, the amount of preparation …
We all want our five minutes in the spotlight. It could be the long-awaited moment you finally get to give an oral presentation at EGU, in front of an audience eager to absorb every single word that comes out of your mouth and every single slide like they are solving all open issues in all the geosciences. But not all research fields are created equal and, let’s face it, some fields seem to be considered the soggy leftover of a …
One year ago, we started a series of blog posts synthesising the main results and discussions about the most significant earthquakes recorded recently, previously called “Earthquake of the month” and now known as “Earthquake Watch.” In our first edition, we reported on the 2020 Simeonof earthquake M 7.8 that occurred in Alaska (read here), and today we return to the same region with another interesting earthquake. On July 29th at 06:15 (UTC), a large earthquake M8.2 occurred in the Alaska …
