Wow, I am so bad at posting wave watching pics recently… Here is everything that happened on my wave watching Instagram @fascinocean_kiel in the last 10 weeks! Enjoy!

Best way to start the day, best way to end the day…

Super muddy stripe in the water parallel to Långa Bryggan. Not right by the bridge where the digger drove through the water, but quite a bit downwind (see Langmuir stripes?) due to the water moving parallel to the coast. Pic 1 before, 2 after a dip. Could probably calculate the current speed from that!

Mud stripes after the digger drives out and back, drifting the other way today

Beautiful day for not one but two swims!

Perfect #wavewatching today!

Yesterday’s swimming in the rain @katarina.martensson

The best way to start the week! @katarina.martensson

Nothing calms me down in quite the same way as these exact shades of blue

Playing in the sea before work! Unfortunately the waves are not quite as impressive as it seems in this pic, it’s just a little water on the lens! But one can always dream…

I used to be a lot more intentional about using social media to talk about interesting work stuff in addition to all the water I look at (although you see that there are plenty of water representations on my desk!). Today I just want to point out that I still have my blog, and that I am still updating it fairly regularly. And yesterday, I wrote about a YOU HAVE TO READ THIS BOOK-book on the science of learning (Zakrajsek, 2022). It’s written primarily for college students, but I think it’s also super useful for teachers. So head over to my blog (link in bio) and check it out!

A favourite #fridykningsfysik experiment is about understanding stratifications in water – why, for example, there is warm water in the surface of Boalt quarry during summer, but as soon as you dive down, it gets really cold. We play with this here by melting pink ice cubes in two cups containing freshwater and salt water. As you can see, in one cup the melt water forms a layer floating on top of the water in the cup, in the other it mixes with the water below and everything becomes pink. Curious about why that is happening? Let us know!⁠

Cold dip and sun, and I’m as happy as can be

Summer dip with unexpected company up close!

Breaking waves in the clouds

They say the water is 10degrees warm now, but it definitely still feels like cold exposure!

After work dips are always good

Windy day, lots of flying sand and thus interesting erosion!

Getting better!

On tornado watch. Someone gotta do it…

It looked so much warmer than it was… But #langmuircirculation!

Super nice excursion backwards (so we start with wave watching, obviously), including fossilized ripple marks in different spots, a collapsed mud volcano, tidal cross-bedding, scratch marks from inland ice, drawings of ships and horses. So much to see in such a small area!

Things I didn’t try beforehand and that still worked out well: asking participants to brainstorm what students do who perform well in their courses, what less successful students do, collecting & clustering keywords for both on the whiteboard, and then projecting this @active.divers training picture on top to stress the point that it is a surface APPROACH and deep APPROACH to learning, and rather than an inert quality in a student, that it’s often a strategic decision which one is being used, and that instruction can encourage one or the other. As soon as I switched on the projector, participants took out their phones and started taking pictures. I like to take that as a sign that this visualization is helpful and that they want to remember it

Growing old is inevitable, growing up is optional

My office this afternoon

New #ActiveDivers depth record: 600m! Luckily only for the styrofoam diver, not for a real one (the current world record is at something around 215 m, and for the disciplines that we do ourselves at around 130 m, in the club 68.3 m). But the styrofoam shows nicely how huge the pressure gets at those depths – it shrinks the whole sphere!⁠
How did we do it? We brought the styrofoam spheres on a research ship to a Norwegian fjord, where the spheres were tied to an instrument that was sent down into the water all the way to the bottom. Now we have a whole series of how much the spheres shrink at different pressures: The normal “dry” one for comparison, then 3,4m (the deepest point in our pool – no shrinkage noticeable), then 50m, 100m, 300m, and 600m! Pretty impressive, isn’t it?⁠

Podcast, iced coffee, dips & this view. Perfect!

No need to go on vacation if you live like this

…and the camera is balancing on a fin that has a second fin as counterweight… I need to work on my camera setup!

Look at these cute little wave rings!

Make a wish

After work walk. In combination with a before work swim, that’s not a bad day…

Some people don’t even recognize what they filled up their driveway with…


Plopping back up

My favourite photo of the day

It’s been more than a week already since we came back from our trip to DeepSpot with a great group of #ActiveDivers, but I’m still processing the amazing experience Lots more pictures over on @active.divers!

#ActiveDivers terminsavslutningen on Sunday. More pictures to follow soon, over on @active.divers! :)
