1/3 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: www.nature.com/articles/d41... @frontiersmedia.bsky.social

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.

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. #FRONTIERSResidency #FRONTIERSfellow #FRONTIERSFellowship

Vor einigen Monaten in der Zeit veröffentlicht - jetzt noch mal im Wissensmagazin P.M. erschienen: Meine Recherche auf den Malediven, wo Forschende die größte Tigerhai-Population im #Ozean und ein kritisches Habitat für den Schutz der Art entdeckt haben. #Haie, #Tigerhai, #SharkConservation, #Shark

Die #Tiefsee der #Arktis gehört zu den unbekanntesten Lebensräumen unseres Planeten. Ich habe ein Team um Tiefseeforscherin #AntjeBoetius auf einer Expedition mit der #Polarstern zum #Nordpol begleitet. Jetzt nachzulesen in der aktuellen Ausgabe von @spektrum.de der Wissenschaft.

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.
