Last #WaveWatchingWednesday of 2020 — this year’s final compilation of my Instagtam posts!

Today with a lot of non-wave watching pics. But who doesn’t love some #KitchenOceanography?

Another episode of the @TreibholzPod podcast (in german) with Ronja, Maxie and myself! We are doing my favorite experiment, looking at ice cubes melting in fresh water and salt water. What can we learn from that about the ocean?

Just gave my first lecture as part of @iearth.no@unibergen — from my parents’ attic instead of my usual “studio” back home, and with internet problems & frozen laptop included to keep it interesting. The fun of doing things online! But there is nothing that can’t be saved by a little #KitchenOceanography, thanks for playing along, everybody! I look forward to work with all of you soon! :)

Today’s wave watching: only in the clouds…

My favourite coffee drink is latte, because
a) it is served in a glass, so you can actually see what’s going on in it, and
b) together with milk, it gives a beautiful stratification, because the molecular diffusion of heat is so much faster than molecules changing places. Super awesome!

A little frost on the grass, some ice on puddles, sun slowly coming up. Perfect day for a #fartlek

More layers in our coffee & milk experiment! But what’s going on on the left where the stratification is being eroded? Any ideas?

Sometimes #wavewatching requires a little effort. But it’s usually worth it!
See the standing waves on the upper side of the weir and then the submerged hydraulic jump on the lower side? I love to discover a hidden wave!

Oh no, it’s already my last podcast episode with Treibholz this year! We are looking at ice cubes frozen from fresh and salt water, and are having a lot of fun, as always when we do #KitchenOceanography! Thanks for having me, Ronja & Maxie!⁠⠀

The heron and I meet up every morning. I think he’s waiting for me and would be disappointed and sad if I didn’t show up. So I have to get there. Obviously. Those are the things that motivate me to go for a run

Fascinating how bubbles eat up other bubbles as they climb up on the edge of the jug. But what makes them stop where they stop? Change in slope? Or are they not stopping, do they just bubble up and leave the smaller bubbles be?

Nix mit Wellen gucken heute

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.daae had the great idea to use it in teaching — send students out to find examples for each of the waves drawn on the “fortune teller”! And, of course, document & share on social media ;-)⁠⠀

Ice forming in needles on puddles with air bubbles trapped underneath and slowly frozen into the ice. I don’t need a lot of water to be happy :)

Did the ice form and the waterlevel drop afterwards? But the water level is regulated in this pond. Very mysterious… But nice ice needles!

Floral pattern in ice on puddle. Pretty!

Ice started forming wherever there were blades of grass or other things penetrating the water surface, and it grew outward from there. But then the water level seems to have dropped over time, leaving those tree-ring-like pattern in the ice

Ice! :)

Made it here before the guys who come here to fish every morning! Small victories ;)

And then I did an update of my content management system and the last picture won’t upload. How much more 2020 can you get? ;-)

[edit 19:41] …but it’s working again, so here are two more pics:

What a pretty checkerboard wave pattern in the middle of the lake!
