We figured out a cheap-ish way to make ocean models create Dense Shelf Waters (DSW) on the surface of the Antarctic continental shelf! How?
Fast answer: Ocean surface cells thinner than 1 m!

We have been lucky in the last 2 weeks and observed sea ice formation. Starting with little ice crystals that can form pancakes or thin grey sheets. Older ice flows from last winter can be 1 m thick and covered in snow. And if there is a penguin on an ice floe - even better.
