Is there any job where the skills tested in the interview are as wildly different from the skills needed to actually do the job as a politician campaigning vs. a politician governing? Curious what examples people have.

And maybe our democracies should change that?

I haven't been to Antarctica, but this photo captures something profound about what a gift it is to do oceanographic science aboard research vessels, and the deep gratitude I feel to be someone who has had that privilege.

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line, which is currently a record low for the current date. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between October and January by looking at the decadal average line positions.

🚨 Friday ice update - #Arctic sea ice extent is currently the lowest on record (JAXA data)

• about 840,000 km² below the 2010s mean
• about 1,380,000 km² below the 2000s mean
• about 2,070,000 km² below the 1990s mean
• about 2,530,000 km² below the 1980s mean

Nares Strait is a gateway for the export of Arctic waters to the North Atlantic. Yet the long-term evolution of its water masses is poorly characterized. Barut et al., use data from 2006–2024 to resolve temporal variability in key mass properties 🐻‍❄️ 🌊

My paper with Susan Allen, @jilian0717.bsky.social, @jaytcullen.bsky.social, & @tiaanderlini.bsky.social is out! We show how Pacific source waters shape property flux into the Salish Sea, and separate dynamical vs property-driven change—useful for understanding coastal conditions in a changing ocean

The 3 graphs show temperature, salinity, and oxygen from the surface to 300 m versus year from 2018 through 2025 for profiling float 5905383. The map shows the trajectory of the float from deployment in the Weddell Gyre (green square) and a loop around the Weddell sea to the present position at the red square.

What's interesting as the Thanksgiving Holiday arrives? The first @bgc-argo.bsky.social profiling floats begin to emerge from under Antarctic sea ice each year. Float 5905383 is the first @soccomproject.bsky.social float for 2025/26. It has spent 7.9 years operating under ice.

From the outset, ONC’s ocean monitoring infrastructure has been designed for multi-use.

This investment has enabled groundbreaking scientific discovery + accelerated ocean tech innovation—while supporting Canada’s evolving needs.

Line graph time series of 2025's daily Arctic sea ice extent compared to each year from 1979 to 2024 as shown with thin lines in colors from purple to white. This graph is for Baffin Bay. There is large daily variability, but a long-term decreasing trend during all months of the year. A seasonal cycle is also visible in this region.

This year's #Arctic sea ice freeze-up is clearly the latest on record for the Baffin Bay region (located between Greenland and the Canadian Arctic Archipelago). The extent of ice cover is a record low for the date there.
