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.
#argofloats #oneargo
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.

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.

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.

Data from @nsidc.bsky.social at nsidc.org/data/seaice_...
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.

Innovation across #Canada's research landscape is inspiring!

ONC wrapped up 3 days of collaborating, sharing insights, & planning for a strong future w/ partners at #CSPC25.

We are proud to be part of the University of Victoria delegation w/ UVic Research & Innovation & UVic ACET.

I don't know if posting pictures of Orion (you can see Orion's Belt there...the 3 stars in a row bottom centre) is useful at all. IMHO it's a big waist of space

Nov. 20, 1933: A M7.3 earthquake struck offshore Baffin Island, #Canada. This is the largest known #earthquake along the passive margin (east/north coasts) of #NorthAmerica and north of the Arctic Circle. This remains a seismically active area:

In our display case @seos-uvic.bsky.social we have some well preserved fossils. For example consider this Pycnodontid, this Trilobite, or this Zip 100 disk…

Can you identify the other fossils? Did you ever use them?

🌊 How do we collect sea ice to measure tor trace elements and isotopes? You need a big drill to collect the core and then a lot of patience to shave down the outsides with a ceramic blade…to get clean ice to melt and analyze. Dr. Tia Anderlini on the trigger here.
