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.

Ah right, full set of numbers, and only 5 seconds of music. It was great how it brought levity and finality at the same time.

Last time I attended was quite awhile ago, and I must admit the timer is my most prominent recollection! Along with a few speakers talking at an ever increasing pace. Could have sworn it was the full 30 seconds, but I bow to you as the original source!

Last time I attended (which was awhile ago) the Challenger Society Ocean Modelling Group meetings had everyone on a strict 10 minute timer, and in the last 30 seconds the countdown music kicked in automatically.

Agreed. A totally pointless activity which never made any sense at any *cough* point in time.

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

Depending on one's perspective, either many trip hazards across the building or one giant trip hazard with many expressions. Although I didn't ponder too much about that when I first entered and fell over with my suitcase in tow.

I once stayed in a hotel in Bergen that had black walls and carpets with a square laser-like pattern across the floor, up the walls, and over the ceiling. And the floor wasn't even as several buildings had been knocked through. Trippy!

The classic mistaking the map for the territory fallacy. The metric should be useful in understanding an element of productivity, but it is accidently used in place of an actual understanding of what it is to be productive.

🌊 New paper!

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

πŸ“ˆ Adding Deep Argo data to GEBCO boosts the Seabed 2030 effort.

You could use a 'region' of the Earth as a starting point. How many 1-in-100 year events happen every year globally?

More importantly, having a rough idea of what was in the book really isn't reading it. I mean, if the value of all books could be extracted to a paragraph, we could just do away with books.

Or am I missing a joke here?

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?"

Allow our scaled diagram to explain...

With the amount of damage to the bow, just getting it safely under tow and into a port looks a bit dicey. Let's hope for some fair weather until it is secured alongside somewhere (preferably straight into a dry dock?)

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.
