Climate hiccups and fisheries management headaches
In Atlantic Canada, the collapse of the Northern Cod stock in the early 1990s forced the government to impose a fishing moratorium that sent 40,000 people into unemployment. It remains the largest ind...

🌊 What is the Meridional Overturning Circulation
and why is it important?
The Meridional Overturning Circulation (#MOC) – critical for transporting heat, carbon, oxygen and nutrients across the globe – is weakening under climate change.

We have a new paper in Science Advances on seasonal movements of the sub-Arctic seafloor. Using sub-annual bathymetry, porewater data, and moored sensors, we observed the seabed expanding and contracting through freeze–thaw cycles, forming seasonal frost blisters.

This false assertion about the ocean producing 50% of the oxygen we breathe is so widespread that @jpgattuso.bsky.social @bopplaurent.bsky.social and others have written about it here.
Humans will always have oxygen to breathe, but we can’t say the same for ocean life
We are not at risk of running out of oxygen due to climate change, but ocean creatures are – and that will harm the whole planet.

As scientists warn that #AMOC may slow/collapse, experts are trying to improve research on this critical ocean conveyor system
We need:

- Global cooperation
- Sustained funding
- New tech for real-time data
