Another episode of the Treibholz podcast (in german) with Ronja, Maxie and myself! We are doing Elin’s favourite experiment (ok, mine too), looking at ice cubes melting in fresh water and salt water. What can we learn from that about the ocean? #KitchenOceanography

DIY #WaveWatching “fortune teller” on #WaveWatchingWednesday
(Download in English || Download in Spanish; thanks to Felipe Veloso for translating!)
How about a little wave watching game to celebrate #WaveWatchingWednesday?
The minute I saw Andrea Lopez Lang’s tweet, where she made a “fortune teller” (no idea that’s what they were called) as going-away and please-remember-what-you-learned gift for her class, I HAD to make something like that!
Unfortunately I’m not teaching a class right now where I could easily see how this could be done, but luckily there is always wave watching!
And Kjersti had a great idea for how this could be used right away: To send students out with these toys and ask them to discover one example for each of the waves shown on the toy. Plus then of course document it, and share on social media… ;-)
Waves are traditionally taught in a theoretical and very dry manner, and the transfer to the real world is hardly happening at all (especially since the large tank in the basement at GFI has been demolished, which still breaks my heart), so this is a fun way to get students outside and try & find contents from their lecture in real life.
P.S.: It’s not as difficult as it might seem at first once you start observing and get a little creative. Nobody said that the rock that makes the ring waves had to have been there when you got there, and wakes can be created by ships or bird or even if you pull a stick through the water…

Treibholz podcast, my second episode in 2020
On today’s Treibholz podcast (in german), Maxie, Ronja and I are playing with #KitchenOceanography again: this time double-diffusive mixing, specifically salt fingering. We had a lot of fun and discovered a lot about experiments and how they seldomly show what one expected ;)
