tank experiment – Adventures in Oceanography and Teaching

Finally published yesterday: “Student guides: supporting learning from laboratory experiments through across-course collaboration” by Daae et al. (2023)

A project near and dear to my heart is using the DIYnamics rotating tank experiments in across-course collaborations. “Older” students, who did experiments the previous year, are trained to then act as guides to “younger” students when they do experiments for the first time, thus lowering the threshold of engaging with equipment, acting as role […]

Learning together across courses — our iSSOTL presentation

mglessmer — Thu, 04 Nov 2021 11:38:47 +0000

Last week, Kjersti Daae and I gave a virtual presentation at the iSSOTL conference, and here is a short summary. We presented an ongoing teaching innovation project, funded by Olsen legat and conducted together with Jakob Skavang, Elin Darelius and Camille Li, that we started last year at the Geophysical Institute in Bergen: Bringing together […]

Solid body rotation

Several of my friends were planning on teaching with DIYnamics rotating tables right now. Unfortunately, that’s currently impossible. Fortunately, though, I have one at home and enjoy playing with it enough that I’m Playing with it Making videos of me playing with it Putting the videos on the internet Going to do video calls with my […]

Thermal forcing vs rotation tank experiments in more detail than you ever wanted to know

mglessmer — Mon, 25 May 2020 12:05:23 +0000

This is the long version of the two full “low latitude, laminar, tropical Hadley circulation” and “baroclinic instability, eddying, extra-tropical circulation” experiments. A much shorter version (that also includes the end cases “no rotation” and “no thermal forcing”) can be found here. Several of my friends were planning on teaching with DIYnamics rotating tables right now. […]

Thermal forcing vs rotation

mglessmer — Sat, 23 May 2020 12:05:57 +0000

The first experiment we ever ran with our DIYnamics rotating tank was using a cold beer bottle in the center of a rotating tank full or lukewarm water. This experiment is really interesting because, depending on the rotation of the tank, it will display different regimes. For small rotations we get a low latitude, laminar, tropical […]

Brine rejection and overturning, but not the way you think! Guest post by Robert Dellinger

mglessmer — Thu, 16 Apr 2020 12:05:58 +0000

It’s #KitchenOceanography season! For example in Prof. Tessa M Hill‘s class at UC Davis. Last week, her student Robert Dellinger posted a video of an overturning circulation on Twitter that got me super excited (not only because as of now, April 15th, it has 70 retweets and 309 likes. That’s orders of magnitude more successful than any […]

New rotating table on #FlumeFriday! Welcome to the family!

mglessmer — Fri, 10 Jan 2020 18:40:41 +0000

In addition to our four DIYnamics-inspired rotating tanks, we now have a highly professional rotating table with SO MANY options! And also so much unboxing and constructing and trouble-shooting to do before it works. But we finished the first successful test: wanna see some rotating coffee in which milk is added? Then check this out! […]

Thermally driven overturning circulation

mglessmer — Thu, 21 Nov 2019 17:11:01 +0000

Today was the second day of tank experiments in Torge’s and my “dry theory 2 juicy reality” teaching innovation project. While that project is mainly about bringing rotating tanks into the theoretical teaching of ocean and atmosphere dynamics, today we started with the non-rotating case of a thermally driven overturning circulation. Very easy setup: A […]
