Back on R/V Kronprins Haakon!
I am currently covering an #expedition with the Norwegian #research icebreaker Kronprins Haakon in the #ArcticOcean. Earlier this week, the ship reached the geographic #NorthPole. Low sea-ice cover allowed for easy passage through the central #Arctic.

Is the #AMOC nearing collapse?
In February, I joined researchers from @bjerknes.uib.no on the icebreaker Kronprins Haakon to the Greenland Sea.
My text and images about their encounters during #Arctic winter and the future of the AMOC:

Shutting down Mauna Loa CO₂ observations while atmospheric CO₂ keeps skyrocketing is like turning off a fire alarm because you don’t like the noise

Mauna Loa Observatory’s Lease May End Because of NOAA Cuts
NOAA, the nation’s leading climate science agency, may lose dozens of offices, including one that is key to the Mauna Loa Observatory in Hawaii.

After four weeks in the #Arctic, I'm spending the next two months of my @frontiersmedia.bsky.social science journalism residency at @gfz.bsky.social in Potsdam. At GFZ, I'm embedded with the team of @lianegbenning.bsky.social who studies the secret lives and biogeochemistry of #glacier #microbes.
For our English speaking friends: We're happy to host journalist and photographer @timkalvelage.bsky.social who will accompany our researcher @lianegbenning.bsky.social in the upcomings months. This was made possible through the FRONTIERS Science Journalism Residency Program of @erc.europa.eu 1/2
Wir freuen uns ganz besonders über einen Gast im Team von @lianegbenning.bsky.social : Der Journalist & Fotograf @timkalvelage.bsky.social begleitet Liane & ihr Team für zwei Monate. Möglich gemacht durch ein FRONTIERS-Stipendium des @erc.europa.eu . Lest mehr dazu hier: www.gfz.de/presse/meldu...

I just started my @frontiersmedia.bsky.social science journalism residency at @gfz.bsky.social and iC3. In the next 5 months, I'll explore how #glacier microbes and meltwater runoff affect the Earth system from the atmosphere to the #ocean.

Alkalisches Gesteinsmehl soll die CO2-Aufnahme der Meere im Kampf gegen den #Klimawandel erhöhen. Wie Forschende vom @geomarkiel.bsky.social die Effizienz und ökologischen Folgen der #Ozeanalkalinisierung untersuchen, habe ich fürs Magazin Bild der Wissenschaft aufgeschrieben.
