Our new 🌊 paper “Progressive oxygenation of the North Atlantic Subpolar Gyre” is out @jgroceans.bsky.social (open access): agupubs.onlinelibrary.wiley.com/doi/10.1029/... We examined the breathing of one of the ocean’s lungs 🩺 and found some surprises Paper summary in schematic, more info ⬇️ 1/🧵

Reminder for those of us who leave things to the last minute - last day to respond to the NSF request for input on ocean observing 🌊 GO-BGC funding is crucial for us to keep putting floats in the water, and for me to keep putting Lego floats in my office!

NSF has funded over 80% of the world's BGC-Argo floats via GO-BGC, which ends in October 2026, so the global array will start shrinking. NSF is asking US researchers to weigh in on future ocean observing priorities: www.go-bgc.org/nsf/nsf-requ...

Turns out my printed-out dissertation is useful for something after all

New paper out for all my North Atlantic ventilation fans! Led by Una Miller @cornelluniversity.bsky.social

Quintessentially Seattle activity of the day: picking up a bunch of beers for a workshop happy hour on my bike

Something feeling very familiar about this England performance at the world cup..

I'm proud to announce a commentary from the Phenomena, Observations, and Synthesis panel of @usclivar.bsky.social about the necessity of the Argo program. 🌊 🧪 You can check it out here: doi.org/10.5670/ocea...

Interested in understanding how the subsurface tropical Pacific has responded to GHG forcing? Interested in understanding whether models and observations agree on that response? Check out our recent paper in @jgroceans.bsky.social! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Look what’s swimming back for a limited time! Donors who give at least $65.13 through the link in this post will get their paws on the shirt as a thank-you gift. mbayaq.co/4vDTCkE.

🌊 Every day, ~4,000 Argo floats observe the world’s oceans. They provide essential, open and freely available data that improve weather forecasts, early warnings systems, and climate predictions. Behind this network: more than 30 yrs of scientific effort. Thanks to all those who keep Argo alive!

Look it’s just typical Paraguayan efficiency. Famous Paraguayan precision engineering. Strict, emotionless Paraguayan rationality. No wonder they’ve never lost a World Cup penalty shootout

Since winning the 2014 World Cup, Germany have won as many knockout games as Italy (0)

I especially love this diagram.

🌊 Ocean monitoring is in trouble: without the US, it’s up to Europe and Asia to avoid losing sight of the world’s deep‑sea ecosystems theconversation.com/ocean-monito...

🌊 New paper alert! For the first time from space, two NASA missions enable us to observe plankton community composition alongside the physical processes that structure it. 🛰️ 🦠 🌀 Check it out from @tosoceanography.bsky.social: doi.org/10.5670/ocea...

Come join us in Seattle for the float data workshop! There will be lots of science, lots of fun people, lots of sunshine*, and of course a soccer game (maybe frisbee too) 🌊 *sunshine not guaranteed, but fairly likely in August

You know you’re American when the only examples of ground transportation you can think of are different ways of having someone drive you in a car

Come join us in Seattle for the Float Data Workshop in August! Perfect for learning how to use Argo data (or getting even better at it), and meeting others in the community 🌊

Every spring, thousands of fish swim through the Oudegracht in Utrecht, looking for a place to lay their eggs. But the Weerdsluis is often closed. The Fish Doorbell helps. When you spot a fish on the livestream, press the doorbell. The lock keeper will check to see if the lock can be opened.

Successful second edition of OSM Soccer at #OSM26 yesterday - guess we’ll need to keep it going in 2028 🌊

Organizers clearly don’t trust the life skills of a room full of scientists #OSM26

SAVE THE DATE! Aug. 2026 @globaloceanbgc.bsky.social Float Data Workshop in Seattle! Get the deets & submit expression of interest here: www.us-ocb.org/go-bgc-float... 🌊

Finally Bach decides to drop some new tracks, feels like it’s been 200 years since the last one

Another reminder that a 13-year study found that protected bike-lanes led to a drastic decline in fatalities for all road users. ALL ROAD USERS. And painted bike-lanes? No safety improvement at all. For sharrows, it’s actually safer to NOT have them. Via @usa.streetsblog.org @nyc.streetsblog.org
