Marine Heatwaves Disrupt Ocean Carbon Pump, Trapping CO2 Near Surface

Alaska Gulf heatwaves – “The Blob” (2013‑2015) and 2019‑2020 – trapped carbon near the surface, with ~660 ft (200 m) and 660‑1,300 ft twilight‑zone accumulation. Read more: getnews.me/marine-heatwaves-disrupt... #marineheatwave #carbonpump

Climate change and terrigenous inputs decrease the efficiency of the future Arctic Ocean’s biological carbon pump - Nature Climate Change Changes in the Arctic could impact the oceanic carbon sequestration of the region. Here the authors consider regional biogeochemistry, including coastal erosion and river inputs, to show a 40% reducti...

Eine neue Studie des #Alfred-Wegener-Instituts zeigt, dass der Klimawandel und zunehmende Einträge von Land (z. B. aus tauenden Permafrostböden) die Effizienz der biologischen Kohlenstoffpumpe #BCP im Arktischen Ozean erheblich verringern könnten.

Our #MarineSnow Catchers come in a variety of sizes, from 50L to 300L. On recovery these giant water samplers have to settle on deck to allow the undamaged marine snow particles to sink to the bottom chamber for sampling. bit.ly/3SkXLam #carbonpump

Better understand the #ocean dynamic, better understand the ocean #carbonpump are part of the missions of the @TaraOcean_ ⛵️ @romaintrouble

All this knowledge, based on #science, is essential to develop solutions to fight against #climatechange 🌏
