Today we are running the last of the seawater samples from the Distributed Biological Observatory project. The research cruise is on the UAF RV Sikuliaq in the Pacific Arctic. #FieldworkFriday
🧪🌊🦑🐻‍❄️ @uafairbanks.bsky.social

Sikuliaq is an Iñupiaq word for "young sea ice".

The Chukchi Sea is approaching ice-over, though substantial areas of now disconnected open water remain. With colder weather this week, ice will grow. Ice is also growing out from the coast in the Bering Sea, and ice extent is near the 1991-2020 median for the end of November. #akwx #Arctic #seaIce

In the latest Global Carbon Budget, the estimate of the ocean carbon sink was increased by 0.8 Gt of CO₂ due to methodological changes.

Each mCDR deployment aims to remove a tiny fraction of that, so if people think we have the methodology to do proper MRV for mCDR right now, they're delusional. 🌊
In our revised assessment, we increase the GOBMs estimate by 10 ₫ 8% and the fCO-products estimate by 0.18 ± 0.4 GtC/yr. These two corrections combined lead to an increase of S_ocean by 0.22 ÷ 0.23 GtC/yr for the 2014-2023 period.

📢Global Carbon Budget 2025📢

Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.

The key findings are covered in two reports this year:
