The scientific publishing we used to know is broken in a way we will not be able to fix. It does not even deserve a fix. Let’s move on.
"Runctitiononal features"? "Medical fymblal"? "1 Tol Line storee"? This gets worse the longer you look at it. But it's got to be good, because it was published in Nature Scientific Reports last week: www.nature.com/articles/s41... h/t @asa.tsbalans.se

100 years ago, research vessel #Meteor set sail to explore the Atlantic Ocean – one of the most important expeditions of the 20th century. To mark the anniversary, GEOMAR and DSM/Leibniz-Institut für Maritime Geschichte launched a storymap.

The current Mediterranean SST anomalies are absurd.
June 2025 mean Mediterranean SST reached 6 of the 10 highest daily anomalies since 1982. The three highest values were recorded in June 21, 20 and 22 with 2.65, 2.57 and 2.51ºC.
A mean Med SST value of 25.1 was recorded on June 23.

These two award-winning scientists illustrate how messed up the system is in 🇩🇪 and 🇨🇭. One had a successful career but had to find a permanent position elsewhere. The other's contract will run out in 3 years. It also illustrates how it won't be easy to accommodate US scientists in these systems. 🌊
🌊 Great medal and award lecture at #EGU25!
Congrats to @tatianailyina.bsky.social for receiving the Fridtjof Nansen Medal and @polarocean.bsky.social for the Outstanding ECS Award for their outstanding work in oceanography👏 Truly great scientists!

Even among marine biogeochemists, I would say there are only a handful worldwide that truly understand "alkalinity" (@agdco2.bsky.social is one and you should follow him), so it's always astounding to me that we're all now using the term casually like this. 🌊

Gemütlich im Mittelbau #einkuscheln?! Ihr wisst: Ich habe #IchBinHanna gestern im Wissenschaftsausschuss des NRW-Landtags vertreten. Was ich da alles gesagt hab? 1 🧵! Da ich vermute, dass Euch das besonders interessiert, fange ich mal mit meiner Reaktion auf das Einkuscheln an. (1/8)
