Totally not the focus of our experiments, but so beautiful! Kelvin-Helmholtz instabilities

September 22, 2017

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…

Standing waves in a current

May 4, 2017

The other day I found the perfect standing waves on a current: This egg-carton-like pattern really stays pretty constant over time and I think the changes in the wave pattern…

Another wave hunt expedition: Learning to discover ocean physics wherever you go

June 21, 2016

One of my favourite topics right now: Learning to “see” ocean physics wherever you go. For example here: A visit to my goddaughter in Schleswig, and this time we are practicing all…

Ice on Elbe river in Hamburg. By Mirjam S. Glessmer

Reading ice on a river as tracer for flow fields

January 21, 2016

For most of my readers it might be pretty obvious what the movement of floating ice says about the flow field “below”, but most “normal” people would probably not even notice that…

Flow separation

April 27, 2015

On the way to the pool I cross over the Elbe river on this pretty bridge. Which is pretty spectacular, just because the structure itself is so amazing. But what…

Waves on a current

April 20, 2015

When you throw a stick in the water and the waves don’t form circles. Throwing something in the water usually results in waves traveling out in circles from the point…

Wave fields around objects in a channel

February 25, 2015

One of the reasons I have been wanting to do the vortex street experiment I wrote about on Monday is that it is pretty difficult to visualize flow fields (especially if…

Wind waves meet current

April 8, 2014

Wind waves on one side of the current – no waves on the other. Recently in Bergen, I was walking to meet up with a friend at the kayak club,…
