Water justice in hydrological research

Water justice in hydrological research

Water justice has become a crucial discussion in the past decades. Some of the core aspects reflect the questions about who gets involved in the decision-making process, who has access to drinking water, or who gains from flood alleviation schemes. Many hydrologists are struggling to find an answer to these major challenges.  The rise of water justice In recent decades, the question of justice in ...[Read More]

Geological TrIPS: The amazing fragments of oceanic crust treasured on the Greek island of Syros

Geological TrIPS: The amazing fragments of oceanic crust treasured on the Greek island of Syros

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. Fortunately, subduction zones can be studied through their anci ...[Read More]

Geodesists on Tour: On a Campaign in the Arctic with a Giraf(f)e in the Aircraft

Geodesists on Tour: On a Campaign in the Arctic with a Giraf(f)e in the Aircraft

  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 I had been preparing a survey to test a new quantum-based technology for airbo ...[Read More]

Geo-Movie Cup 2023: Dante’s Peak’s Explosive Victory

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 year ...[Read More]

Assessing the impact of chlorine ions on solar proton event induced ozone loss

Assessing the impact of chlorine ions on solar proton event induced ozone loss

  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-dissoc ...[Read More]

Towards an exciting EGU General Assembly with HS (and more)

Towards an exciting EGU General Assembly with HS (and 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]

A ‘Ticking Bomb’: Understanding the 2023 Glacial Lake Outburst Flood (GLOF) in Sikkim Himalaya

Two photos of a glacial lake, on the left in 2022 and on the right in 2013, visually smaller.

  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 observations and monitoring for people’s livelihoods. The South Lhonak L ...[Read More]

Slow Evolution of Europa’s Interior

Slow Evolution of Europa’s Interior

“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 of Europa’s interior. One of the most promising p ...[Read More]

Geodetic reference frames – Why do we need them?

Geodetic reference frames – Why do we need them?

  A geodetic reference frame provides the foundation for determining positions on Earth and in space, as well as for reliably quantifying our planet’s changes due to geodynamic processes and ongoing climate change. The ITRF ensures a uniform basis to tackle current and future challenges, including a wide range of location-based applications (navigation, traffic and fleet management, transport ...[Read More]
