🌊 Great medal and award lecture at #EGU25! Congrats to @tatianailyina.bsky.social for receiving the Fridtjof Nansen Medal and @polarocean.bsky.social for the Outstanding ECS Award for their outstanding work in oceanography👏 Truly great scientists! Check out the interviews: bit.ly/3ScAwQp @egu.eu

I am excited about my Fridtjof Nansen Medal Lecture tonight at #EGU25. It is about ocean carbon cycle, its predictability and feedbacks in the Earth system - topics I am truly passionate about. Hope to see many colleagues there 🧪 🌊 meetingorganizer.copernicus.org/EGU25/sessio... @egu.eu

At #EGU25, I gave an interview with respect to the Ocean Sciences @egu.eu #EarlyCareer Award. It is about my past, present and future science and also being a parent in academia! If you want to hear more, please come to my medal lecture tomorrow: meetingorganizer.copernicus.org/EGU25/sessio...

Interested in the freshwater distribution and variability in the Southern Ocean 🌊 ? Come by my #EGU25 presentation where I will show new insights from oxygen stable isotopes! 🗓️: Monday April 28 🕰️: 14:32 - 14:42 ⛓️‍💥: meetingorganizer.copernicus.org/EGU25/EGU25-...

Love the ocean 🌊? Love science 🔬? Want to get involved in some cool ocean research 🙋‍♀️ I've just updated the list of marine-themed community/citizen science! ➡️ www.oceanoculus.com/...

A new estimate of the composite model-based estimate of the annually averaged ocean carbon sink. 🌊 This composite model-based estimate of the ocean carbon sink from 1959 to 2022 is similar in magnitude to the best estimate of the Global Carbon Budget but 70 % less uncertain.

The use of civilian platforms for #oceanobservation is a viable & sensible method to expand the capacity of the observing system. Get the scoop on the proof in the paper by @jacbeh.bsky.social, Peter Landshützer & Toste Tanhua www.nature.com/articles/s41... @horizoneu.bsky.social #REA #citscience

💰 Weaker ocean circulation may cost trillions A new study by @felixschaumann.bsky.social and @edualastrue.bsky.social in @pnas.org reveals that a weakening Atlantic Meridional Overturning Circulation (AMOC) could lead to costs of several trillion euros. #CLICCS #climate #ocean @uni-hamburg.de

🌊⛵ In 80 days Boris Herrmann sailed around the world, not just for the sport but also to aid climate research by collecting valuable ocean pCO2 data in remote regions. 🎥 Check out this German documentary focusing on his #ClimateProtection efforts and for which I was also interviewed: bit.ly/4grKcjU

Hamburg sailor Boris Herrmann crossed the finish line of Vendée Globe. Howling winds and roaring waves was not the only challenge on the way. As in the previous races, his sailboat has been collecting precious CO2 data. This matters for improving our understanding of the ocean carbon sink! 🧵 🌊🧪

🌊 Ready to make a big splash, TRICUSO wrapped up its kick-off in Southampton this week having set groundwork for a 4 year journey to develop technology & methods to address the #Carbon #Sink Status of the #Southern #Ocean in support of the #WMO Global Greenhouse Gas Watch. #Climate #research

Introducing our new project - TRICUSO - Three Research Infrastructures Carbon Uptake Southern Ocean. We aim to integrate effort from surface CO2 observations within ICOS, deep observations from GOSHIP and Argo as a contribution to the WMO Global Greenhouse Gas Watch @tricuso.bsky.social 🌊

Working on or interested in "Budgets, trends, and drivers of major Greenhouse Gases in the atmosphere, on land, and in the ocean from regional to global scales"? Please consider submitting to our session at EGU25 (meetingorganizer.copernicus.org/EGU25/sessio...). See you soon 🌊

🌊 Ocean book review on the EGU #OceanSciences blog 🌊 I have read and reviewed "Blue Machine" by @helenczerski.bsky.social, and I highly recommend it. (Btw, it's perfect as a Christmas gift!) Any book recommendations for us to explore next? 📚💙 blogs.egu.eu/divisions/os...

The ocean was unusually hot in 2023 👇 We found that this caused an unexpected decline of the ocean carbon sink, primarily driven by anomalous outgassing of CO₂ in the northern hemisphere extratropics. ▶️ doi.org/10.21203/rs.... Feedback on our preprint is more than welcome! 🌊

Applications for both positions are now open! Deadline for both is January 3, 2025. Please get in touch if you have questions.

👋 Hello Bluesky! 👋 I'm Jacqueline, a PhD at the Max Planck Institute for Meteorology, and I am interested in everything related to #ocean #carbon. 🌊 I use machine learning and #observations (especially from sailboats) to study the ocean carbon sink. ⛵ 📝 Check out our papers below where we:

Ocean Acidification is reshaping life and biogeochemical cycles.

📢Today the Global Carbon Project releases its 2024 edition of the Global Carbon Budget, a comprehensive assessment of our perturbation of the carbon cycle and the balance of sources and sinks of CO₂. 1/🧵

📢Global Carbon Budget 2024📢 Despite some predicting a peak in global fossil CO2 emissions, we estimate growth of 0.8% [-0.3% to 1.9%] in 2024. Maybe a peak next year? Is it all bad news, or can we find some good news? essd.copernicus.org/preprints/es... 1/

The ocean takes up anthropogenic CO₂ emissions, 26% on average over the past decade. The #GlobalCarbonBudget 2024 confirms that the ocean sink increased in 2023 after 3 years of stagnation due to rare triple La Niña event. 2023 was an El Niño year, with an expected increase in the sink. 🔽 🌊 1/10
