After a pause, the Geochemistry, Mineralogy, Petrology and Volcanology division’s early career scientists talks (EGU campfires) are back! The first session in 2023 will be a special relaunch event. It will be held on Thursday 16th November at 4pm CET on Zoom. For this special edition, our speaker is Xin Zhong (PostDoc @ Freie Universität …[Read More]
Geologists are often fascinated by the processes (and their products) taking place at the sea. Perhaps the fact that we do not have easy access to most of these processes is what puzzles us as geoscientists. Subduction can be considered as one of these “mysterious” processes for which several mechanisms remain to be better understood. …[Read More]
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 …[Read More]
Ladies and gentlemen, disaster movie aficionados, and geological enthusiasts, it’s time to revisit the epic showdown that was the Geo-Movie Cup 2023. This year, the competition reached unprecedented heights, welcoming new movies into the mix, adding Instagram as a polling platform, and ultimately crowning “Dante’s Peak” as the winner. Let’s dive in and recap this …[Read More]
Today, 3 November, is globally recognized as the International Day for Biosphere Reserves. The first edition of this observance day was marked last year, with UNESCO urging our relationship with nature needed “a radical rethink.” As Audrey Azoulay, Director-General of UNESCO explains, “The logic is simple: to improve our relationship with nature, we must first …[Read More]
Particle Precipitation High energy particles (e.g. electrons and protons) that precipitate at high latitudes can alter the chemical composition of the atmosphere by different photochemical reactions. This mainly happens due to primary collision processes and subsequent ion and neutral-chemistry reactions. Such reactions ordered by increasing energy are, for example, excitation, photo-dissociation, photo-ionization and dissociative …[Read More]
The EGU Programme Committee convened in late October to finalize the scientific program for the upcoming General Assembly, GA2024. Their task involved organizing the numerous session proposals, spanning 22 divisions, including Inter- and Transdisciplinary (ITS) sessions, discussing the format of scientific sessions (do expect news for virtual posters and PICOs at GA2024!), the mentoring programme, …[Read More]
In this week’s blog post, Dr. Remya S N and Dr. Vishnu Nandan talk about how optical and radar satellite images were used to characterize the very recent catastrophic Glacial Lake Outburst Flood (GLOF) from the South Lhonak Lake in the Indian Himalaya before and after the flooding and highlight the importance of timely …[Read More]
“Europa may be one of the most promising places in our solar system to find present-day environments suitable for some form of life beyond Earth.” This week in News & Views, Kevin Trinh, a PhD student at Arizona State University, discusses how his recent works on Jupiter’s moon Europa can enlighten us about the evolution …[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights roundup. For October, the Divisions we are featuring are: Planetary and Solar System Sciences (PS) and Solar-terrestrial Sciences (ST). They are served by the journals: Annales …[Read More]
