Helene Hollitzer @helenehollitzer.bsky.social · 11/03/2026New preprint out 🌊 We investigate how terrigenous inputs from rivers and coastal erosion affect ocean acidification in the Arctic Ocean using an ocean biogeochemical model constrained by observations. 🔗 doi.org/10.5194/egus...doi.orgContrasting effects of river and erosion-derived inputs on Arctic Ocean acidificationAbstract. Although the Arctic Ocean is relatively small in volume, its extensive coastline delivers large quantities of terrigenous material from rivers and coastal erosion. As a result, the Arctic Oc... 110

Reposted by Helene HollitzerJens Terhaar @polarocean.bsky.social · 15/01/2025Has the Atlantic Meridional Overturning Circulation (AMOC) weakened over the last decades? In our new study, we combine state-of-the-art CMIP6 models and observation-based estimates of the air-sea heat flux in the North Atlantic to show that the AMOC has not declined since the 1960s! 🌊nature.comAtlantic overturning inferred from air-sea heat fluxes indicates no decline since the 1960s - Nature CommunicationsThe AMOC is crucial for the global ocean overturning circulation and controls the climate around the North Atlantic. Here, the authors use 24 Earth System Models from the CMIP6 to demonstrate tha... 25443159
Helene Hollitzer @helenehollitzer.bsky.social · 15/01/2025🎙️ I'm happy to present at the next GO2NE webinar on 21 January! I'll be sharing our recently published research showing that the effects of wind and buoyancy forcing on global #ocean #deoxygenation have partially offset each other since the 1960s. 🌎🌊 011
