Mir fällt auf, dass das Buch, das ich gerade im Zug lese, viele misstrauische Blicke auf sich zieht 👀Aber es liest sich gut.

The comfy Nightjet #Train2EGU took me directly to Vienna. There were many people with poster tubes in it 👀
Looking forward to #EGU25

Getting together for some mulled wine at the cozy, nearby Christmas Market 'Christgrindelmarkt' to chat about ocean carbon cycle, cats, model development, families, Hamburg weather, people's pathways in academia, hobbies, recent papers, plans for next year, etc. has become our group's tradition.

Male members only - is written on the wall in the lobby of a college not far away. Women, if there were any at that time, had to use the back door.

As I was told, they tried but were not allowed to remove this inscription because of the monument conservation law.

Looking with horror at the current status of the elections. Who are all this people?

How do strong tropical storms, such as hurricanes and typhoons, drive changes in CO2 fluxes between ocean and atmosphere?

Our simulation with a horizontal resolution of 5 km in the ocean and atmosphere allows representing such phenomena in the atmosphere and also mesoscale eddies in the ocean.

This was an opportunity to remind that it was Eunice Foote, who was the first to measure the solar heating of CO2, already in the 1850s :

„An atmosphere of that gas would give to our Earth a high temperature“ - she wrote in her paper published in American Journal of Science and Arts, 1856.

This first week of the winter semester, our new Oceanography students at @uni-hamburg.de @cenunihh.bsky.social have their orientation events.

I look forward to inspire them with modeling the ocean carbon cycle as an interactive component of the Earth system 😍

Lucas Carnier Casaroli presented results of his PhD project "Interannual Variability of Dissolved Inorganic Carbon in the Equatorial Pacific: The Influence of Tropical Instability Waves and ENSO". His results are getting mature enough to becoming a good PhD thesis.

Hwa-Jin Choi who joined my group only two weeks ago presented a mix of her previous work and the concept for her new project "Evolution of the ocean’s anthropogenic carbon reservoir under changing emissions".

Very proud of the presentations by PhDs from my group! Looking at them makes me want go back in time and start working on a PhD again 😉
Danai Filippou started her project "Ocean Compound Extreme Events and their Predictability" only in the summer and already presented first results. 🌊

🌊 In this study we show that coastal permafrost erosion weakens the Arctic Ocean CO2 uptake by 7-14%. This exerts a weak positive biogeochemical feedback on climate, increasing atmospheric CO2 by 1–2 TgC  per year per °C of rise in global surface air temperature.

This new ICON-XPP model is our working horse for the upcoming CMIP7 climate projections. It will also remain the horse we are working on for a while 😉
At an all-hands workshop at the Seewetteramt #Hamburg last week we discussed progress and challenges.
