We’re excited to welcome Brazil & Steph Muchai as OGP’s Co-Chairs and to spotlight UK & Laura Neuman, who will follow in 26–27.

Brazil & Steph’s Co-Chair Agenda sets bold priorities for #opengov.

Since it's coming up again in the Discourse: GPS (GNSS) is a passive system and does not itself actually track anything. The satellites just shout out their own position & time.
Your device just listens to that, works out its position, and may store or transmit that data through a phone connection.

Dip-test question: without looking it up, what do you think "open government" is?

🌊 New paper!

Deep Argo floats don’t just profile the deep ocean, they now improve global seafloor maps!

📈 Adding Deep Argo data to GEBCO boosts the Seabed 2030 effort.

On the anniversary of the sinking of the Titanic, we thought we'd answer a question that's often asked,

"If they raised the Mary Rose, why not raise the Titanic?"

Incredible work from @ptfretwell.bsky.social, Hamish Pritchard, and the Bedmap team...!

So much depends on the topography beneath the Antarctic Ice Sheet, including the future of sea level rise across the planet - and this new work will really help us understand and prepare.

It’s 10 days into the new year & @globaloceanbgc.bsky.social & @soccomproject.bsky.social have already deployed 10 new @bgc-argo.bsky.social profiling floats. 410 in the water, 70 with chem & 332 have chem/bio sensors - O2, pH, NO3, & bio-optics. They sample the upper 2 km
every 10 days. 🌊⛴️🌡🧪

🌊🧪@bgc-argo.bsky.social Float of the Month. WMO 7900823 deployed nearly 80 south in the Ross Sea has done 2 years under ice. Here's the data plot (all data freely available @soccomproject.bsky.social). No bloom this year! Too much ice melt, no deep mixing, and no iron to feed plankton - IMO.

At the covid inquiry today, Matt Hancock was forced to look in our direction as we held up pictures of our lost loved ones. He was also forced to look at a photograph of our beautiful wall, displayed in the hearing room, where nearly a quarter million of our beloved covid dead are remembered. ♥️

A brief history of climate science:

1822 - Joseph Fourier suggests the atmosphere behaves like a greenhouse

1857 - Eunice Foote suggests that CO₂ is the gas responsible

1861 - John Tyndall identifies the main greenhouse gases which absorb infrared radiation: H₂O, CO₂, CH₄

Just met my neice for the first time, who is less than two weeks old, and it struck me that she is already infinitely better at understanding the world around her than the best GenAI.

Optimist: the cup is 1/2 full

Pessimist: the cup is 1/2 empty

Contextualist: whether the cup is half full or half empty depends on whether it is being filled or emptied.
Optimist: the cup is ½ full

Pessimist: the cup is ½ empty

Oceanographers: the amount of water is not the issue…
Optimist: the cup is ½ full

Pessimist: the cup is ½ empty

Land and climate expert trained in counterfactuals: ok, how much water was in the cup yesterday? How much was in the cup last year? And how much was originally in the cup before humans started altering it for drinking purposes?
