Did you know that cracks play a large role in the Arctic sea ice production?

Guillaume Boutin April 7, 2023

What do you need to form sea ice? Well, you can start with some sea water, an ocean will do, and cold air above it. Once a layer of ice starts forming, break it to make some cracks. You would have not thought of that? Yet, our recent study suggests cracks in the ice contribute significantly to Arctic winter sea ice production. A relationship between sea ice formation and breakup? We have known for ...[Read More]

ECS SpotLight: Changes in the climate dynamics have already modified characteristics and impacts of storms in France: the case study of storm Alex 2020

Mireia Ginesta-Fernandez April 6, 2023

Extratropical cyclones play a key role in modulating the precipitation and wind in mid-latitudes and can be responsible for extreme wet and windy events. With global warming, the dynamics and thermodynamics associated with these atmospheric systems are being affected. However, due to the complexity of modelling the climate system, a challenge arises when evaluating the influence that climate chang ...[Read More]

Paper focus: Plumbing the depths of magma crystallization by Hugo Moreira and co-authors

Inês Pereira April 5, 2023

Do you know when you stumble upon a very interesting paper, with a captivating title and you wish you could talk to the author(s)? Well, I did just that. It happens that I know the first author quite well, so I had no shame in contacting him and ask about it. One of his latest papers was published in Geology with the title “Plumbing the depths of magma crystallization using 176Lu/177Hf in zi ...[Read More]

The Legend of Zelda: A Link to Learning Hydrology?

Taylor Maavara and Lewis Alcott April 5, 2023

Can we learn about hydrology through video games? Plenty of educational video games exist specifically to teach scientific concepts, but lots of these games are not particularly fun. But can popular commercial-off-the-shelf (COTS) video games fulfill the same function of teaching players scientific concepts through tangential learning as a secondary benefit to enjoying the game? Existing peer revi ...[Read More]

Earthquake Watch: The 6 February 2023 Kahramanmaraş Earthquakes – A catastrophic day for Turkey

EGU Guest blogger April 3, 2023

Assoc. Prof. Dr Onur Tan from Istanbul University-Cerrahpasa outlines the 6 February 2023 Kahramanmaraş Earthquakes for the Earthquake Watch. February 6, 2023, was a catastrophic day for Turkey. The most destructive earthquake in the last century, Mw 7.8, hit the eastern part of the country at 04:17 local time. Unexpectedly, the second Mw 7.5 mainshock shook the region nine hours later. The mainsh ...[Read More]

Tropical conditions in southern Germany: Investigating the sedimentation of Middle Jurassic shallow marine environments in the South German Basin by cyclostratigraphy

Katharina Leu March 31, 2023

Most people would not relate Central Europe to a tropical environment today. During the Middle Jurassic (174-163 Ma ago), however, such conditions prevailed in most parts of the nowadays landmass that was almost completely covered by a shallow epicontinental sea (estimated 0-100 m water depth) except for several emerged areas and islands. During this time, the continent of Pangaea broke apart, as ...[Read More]

Highlighted Paper – The ice factories of the Arctic Ocean

Jakob Dörr March 31, 2023

Each year, the Arctic sea ice goes through a cycle of melting and freezing. From March to September, sea ice gradually melts and becomes thinner, and from October to March, the water freezes again. In our warming climate, we see that more and more ice melts each year. One would expect that the ice would also freeze less, but we have observed that the ice growth – or ice production – has increased ...[Read More]
