If you’re at #OSM26 in Glasgow, I’ve just signed lots of copies of Blue Machine that are now on sale in the shop at @glasgowscience.bsky.social 🌊🌊 Share the ocean love!

Extremely insightful and complex study on ocean alkalinity enhancement under different future emission scenario. Congratulations to @jhauck.bsky.social and team. This is a great primer for many of the things we plan to elaborate further in #OAEMIP.

🌊 New paper out assessing the potential of Ocean Alkalinity Enhancement (OAE) to mitigate the impacts of ocean acidification on marine calcifiers doi.org/10.1021/acs....

🌊

Want to understand how the world’s first carbon credits for ocean alkalinity enhancement were issued? Anna Madlener — one of the new colleagues I’m extremely excited to work with at the Carbon to Sea Initiative — has you covered: www.carbontosea.org/2025/11/25/a...

🚨 The Global Carbon Budget 2025 has just been released and I actively contributed for the first time 😍

Future atmospheric and ocean warming over the 21st century might be larger than previously expected based on a new study by @linusvogt.bsky.social Linus & I developed the idea during Linus research visit with me at @whoi.edu and turned it then into this paper: esd.copernicus.org/articles/16/...

Call for #abstracts – Ocean Sciences Meeting 2026 🌊 📅 February 22–27, 2026 📍 Glasgow, Scotland We are excited to announce our #OSM26 session: CC019 – Ocean uptake, transport, and storage of heat and carbon Details and submission: agu.confex.com/agu/osm26/pr... See you in Glasgow! ✨️

A study in Nature Climate Change shows that the ocean carbon sink unexpectedly declined in 2023 despite record-high sea surface temperatures (SSTs), primarily due to SST-driven outgassing of CO2 in the subtropics. 🌊 🧪

History made for the ocean: #BBNJ Agreement enters into force, protecting high seas & deep seabed, safeguarding life under water. “Our ocean is the foundation of our very existence. Today we took an important step forward to save our ocean, & to save our future” - ED @ingerandersen.bsky.social

1/n This study led by @aaronferderer.bsky.social tested how 5 diatom species respond to broad ranges of seawater carbonate conditions. Goal was to determine carbonate chemistry niches and to inform Ocean Alkalinity Enhancement (OAE) and Ocean Acidification (OA) 🌊 www.science.org/doi/10.1126/...

🌊 Very exciting opportunity in ocean physics!

🚀 Exciting next step: I’ll soon start as a Research Fellow at Carbon to Sea! 🌊

Round 1 of the second science seminar for #AntarcticaInSync - an international collaboration aiming at advancing research of all kinds in Antarctica + the Southern Ocean. Fear not if you missed it, there is another chance Wednesday at 15:00 UTC www.antarctica-insync.org/2nd-antarcti...

Every measurement matters 👏👇

news.climate.columbia.edu/2025/09/04/t... We've had a new analysis published on the impact on the ocean carbon sink from the unprecedented ocean warming of 2023.

Great news study of the global ocean carbon sink response to the 2023 warming conditions

🌊 In 2023, the ocean carbon sink weakened for the first time in a record-hot year 🌡️🌎 Our new study in Nature Climate Change quantifies this unexpected decline and explains how it came about. 👇 doi.org/10.1038/s415...

🌊With the Fall semester upon us, it's time to start thinking about recruiting/applying to grad school for 2026. If you are a marine scientist looking for a graduate student, I've created a form where you can add your name and other info: docs.google.com/forms/d/e/1F... Please share widely! (1/2)

Today at #EGU25:

🌊 #EGU25

A new ocean modeling study by HOLLY OLIVAREZ, NICOLE LOVENDUSKI, et al. suggests that recent slowdowns in carbon absorption may be due to natural variability instead of global warming. But a definitive answer requires more frequent & wider sampling of ocean chemistry www.colorado.edu/today/2025/0...

Good morning #EGU25! Do you want to know what the record high sea surface temperatures did to the ocean carbon sink? Come and see me after the coffee break (11:35) in Room C: meetingorganizer.copernicus.org/EGU25/EGU25-...

My #EGU25 starts w/ a session on global budgets and drivers of greenhouse gases with solicited talks by @jens-d-mueller.bsky.social on the ocean sink under record high SST in 2023/4 Santiago Botía on what it meant for the drought in South America and land sink in the Amazon, Cerrado and Caatinga

🌊 The N.Atlantic has been experiencing extreme T°C in 2023. This situation raises a number of questions: Have we missed something? Do climate models allow us to understand such an event, or have we entered a new climate regime? We attempted to answer these questions in this study: rdcu.be/eh0e8 1/14

A record increase in the global average atmospheric CO2 in 2024, 3.75 parts per million (previous record was 2.96ppm). The global average is more representative than Mauna Loa, as it is the average of numerous stations located around the world. gml.noaa.gov/ccgg/trends/... 1/

I am happy and grateful that I could contribute and work on this extensive review of the carbon cycle across the Arctic land-ocean aquatic continuum. 🏞️ 🌊 Have a look! The Arctic is such an amazing and interesting fast changing region in the world! www.nature.com/articles/s43...

🌊 Extreme Sailing for Science⛵ Ollie is now crossing the Tropical Atlantic, a region where diazotrophs really express their superpower. You don't know what diazotrophs are or why they matter for the carbon uptake capabilities of the ocean? Then check out our latest post ⤵️ @swisspolar.bsky.social

@glenpeters.bsky.social makes an important point here. I often ready in 🌊 #mCDR papers: IPCC says we need #CDR to achieve our climate targets, as all scenarios that reach these goals include a certain level of CDR. 1/2

Shout out to my science colleagues! What thickness of a diffusive boundary layer is realistic assuming very turbulent water? I find a lot online, but no clear estimates. Thanks in advance, Michael Feel free to repost for range 😘
