I’m back at my happy place — the teaching lab at GFI in Bergen! :-)
Here a quick look at what we’ve been doing today: Filling the large wave tank! With clear fresh water and then salty pink water that forms a layer below. As the pink water flows underneath the clear water, there is shear between the two layers, waves form and then they break. Beautiful Kelvin-Helmholtz shear instabilities!
Why have we filled the large tank? Just you wait and see… ;-)
