New SERC “Teach the Earth” Activity on “Ocean Currents and Overflows”
One day in the office at the Geophysical Institute in Bergen last Friday, and for the first time in a long time I am writing a little bit of oceanography…

Rheoscopic fluid
I just wanted to quickly clean my tank… But then it was too pretty, so I guess the rheoscopic (“current showing”) fluid gets to stay a little longer. What an…
Totally not the focus of our experiments, but so beautiful! Kelvin-Helmholtz instabilities
This is really not the focus of our experiments here in Grenoble, but they are too nice not to show: Kelvin-Helmholtz instabilities! They showed up really nicely in our first…
How the strength of the current influences which path it takes. First observations!
Depending on how strong a current we introduce in the 13-m-diameter rotating tank to simulate the strength of the coastal current in Elin et al.’s 2016 article (link on our…
Temperature-driven overturning experiment – the easy way
In my last post, I showed you the legendary overturning experiment. And guess what occurred to me? That there is an even easier way to show the same thing. No gel…
A very simple overturning experiment for outreach and teaching
For one of my side-projects I needed higher-resolution photos of the overturning experiment, so I had to redo it. Figured I’d share them with you, too. You know the experiment: gel…
Currents caused by thrusters
Or: fast inflow into nearly stagnant water body Did you ever notice how when certain ferries dock, they stop, already parallel to the dock, a couple of meters away from…
Currents on soap bubbles
There are currents and eddies and whirls everywhere! Today, Rolf showed us currents on soap bubbles. Check out the movie below for moving pictures!
Marsigli’s experiment
Density-driven flow. The experiment presented in this post was first proposed by Marsigli in 1681. It illustrates how, despite the absence of a difference in the surface height of two fluids,…
