(Remotely controlled?) DIYnamics kitchen oceanography experiments

On this page I’m sharing a bunch of videos that I did in my kitchen, using the DIYnamics setup for a rotating table. I’m recording these videos because several of my friends were planning on teaching with this exact setup right now, but can’t due to Covid. So I thought this might be the next best thing: I record videos, and then my friends can ask their students to watch them in preparation for a video call with me, where they can “remote control” the experiment by telling me what to do. These videos as well as the video calls are meant to complement the theoretical studying going on in lectures and exercises. They are NOT polished, stand-alone teaching videos, they are just me rambling while I am running experiments!

Intro video: Why are we in my kitchen today?

Giving the context & explaining the setup of rotating table and cameras.

Solid body rotation

Running a tank to solid body rotation and discussing why that is important for tank experiments.

Bottom Ekman layer

Stopping a tank that was spun up into solid body rotation to watch a bottom Ekman layer develop.

Rotation vs thermal forcing; “Hadley cell”

Showing the full spectrum from “thermal forcing, no rotation”, over two experiments which include both thermal forcing and rotation at different rates, to “no thermal forcing, just rotation”

Both very slow and fairly fast rotation to compare a 3D overturning and a 2D eddying regime, full length documentation of the experiments.

Planetary Rossby waves

Using an ice cube melting on a sloping bottom to create planetary Rossby waves.

Also check out the video below that shows both a top- and side view of a planetary Rossby wave, filmed with a co-rotating camera.
