#WaveWatchingWednesday

The arrow is pointing the wrong way: both roll waves (on the asphalt) and “normal” waves (on the stones on the edge of the street) are coming down the hill, towards us!
Actually, the waves on the right are standing waves and they are not going anywhere, it’s just the water that is coming towards us in that case!

So here we are, crossing a bridge on a bus, watching the wake of a ship that has disappeared into the fog… Happy weekend!

My happy place

#WakeWatching, without even getting up! Love it! Happy weekend, everybody!

Coffee with a view while planning #KitchenOceanography for the @iearth.no #GeoLearningForum2021!

Does it count as #KitchenOceanography if I make a vortex to poach an egg?

This place is absolutely awe-inspiring. It isn’t even a particularly windy or wavy day, yet with a bit of a funnel, there are enormous amounts of energy crashing here. See the old bridge supports and people on the other side for scale… Also love the contrast of that huge wave and the bunch of small waves where the spray hits the still puddle in the foreground! Very much un-tamed nature…

I look like I’m wondering whether it’s a good idea to turn my back to all that wave power…

The water on the right was brought up there by an earlier wave, falling back down when the next one is already coming. Surprising I ever managed to leave this amazing spectacle!

Still playing with coffee #KitchenOceanography for #GeoLearningForum2021. Which version do you prefer, dark on white or white on dark? And what color should the dark color be? You can’t really make it out, but it’s a dark blue right now…

On the right side of the weather…

After a lot of rain last night, the water is shooting down the rocks so quickly that the sea is struggling to keep the water level up in that spot! Submerged hydraulic jump!!

Can you see that you are standing at the end of a narrow pier?
From both sides, waves are refracted, coming into the spot right in front of us, the center of the concentric circle segments mark the edges of the pier!

Lots of fishies and comb jellyfish! So cute!

What would I be willing to miss a bus for? Taking pictures of waves! In this case, roll waves! Very cool.
Would other people be willing to miss a bus for pictures of waves? Judging from L’s back, probably not

If a weekend has to end, at least make it a double rainbow while waiting at the bus stop…

Planetary Rossby waves in our rotating #DIYnamics tanks! One of my favourite experiments ever!

Lots of lightbulb moments everywhere!

Just in case you weren’t sure how I feel about rotating tank experiments… For today’s class, I made heart-shaped ice cubes! Which we got to use with a bit of a delay because of a fire alarm in the building with the freezer…. :D

Looks like spring has arrived!

Made the most out of a sunny evening!

Oh look, this is actually a pretty good light to take pictures of roll waves! Interestingly, these are not evenly spaced, there are larger ones that overtake the others and eat them up!

Good night, Bergen!

Here we have roll waves and standing waves in very close proximity. What’s different? I’d assume roughness of asphalt is similar, slope is similar-ish. Only water depth might be slightly less where roll waves, those gushes of water that are pulsating down the hill, form. Pretty cool!

You all had better be ready for some serious #KitchenOceanography at #GeoLearningForum2021! We will put the coffee breaks to good use!

Bye bye for now, Bergen!

Don’t know how anyone can work on #bergensbanen. All I can do is look out of the window and take way too many pictures! So glad there is more water in the rivers this time around!

Fascinated by the different textures of the water surface! Why this smoother stripe in the middle? I have NO idea!

I love water. How amazing does this river look?

Waterfall

Perfect start of the weekend: #WaveWatching IN coffee!

As @kjersti.daae says: “Frozen water can smile!” If that’s not enough of a reason to post this…

Waves coming round the island on both sides, making cool interference pattern!

Waves being dampened out by those grass stems or whatever they are. But looks so beautiful!

Someone got cold feet!

And suddenly we were out of the snow again! Luckily there is plenty of water everywhere ;)

Cool waves are radiating from the strong current, so cool!

Super cool standing waves in a shallow but wide stream aka the path…

We call this wave “the zipper”

I love waterfalls

Much more water this time round! And I love standing waves that constantly break upstream but can never fill the dip created by the strong current!

So impressive with the low clouds trapped in the valley!

Never seen this before: Hoar frost combined with frozen water droplets. So what do we think happened here? Rain, then sudden drop in temperature to create frost?

Beautiful weather for a hike! Plus ice on puddles

An ocean of clouds does count for #WaveWatching, doesn’t it?

When @kjersti.daae pointed out the many levels of clouds, I had already forgotten the lowest one, which we had crossed

So cool: water trapped behind the falling curtain of water and the submerged hydraulic jump! See the higher water level in the back?

Isn’t this just soooo beautiful? And fascinating how some of the water is trapped in the boundary layer, running down along the rock, and some shoots over the edge and goes flying?

Halo! So apparently it’s cold enough for ice crystals up there…

Drove through #winterwonderland today!

Just gave a presentation at @geohyd_unioslo on #KitchenOceanography using coffee (my super cool new postcards did arrive exactly on time, so happy Vanja went and picked them up!)

So happy that people started playing with coffee & milk, and actually got beautiful layers!

Apparently this is what it looks like when I talk about #wavewatching and #kitchenoceanography

Full moon over Oslo fjord

Good morning, world!

shooting away from the point of impact, then a hydraulic jump, then flowing water, very nicely visible here!

Day 2 of playing with coffee & milk, and then ice cubes and salt, and eventually softice and whatever else was left of the coffee break. So much fun! The top left one is the double-diffusively layered latte experiment I was going for, the rest was open exploration. @kjersti.daae’s & my contribution to @iearth.no’s sharing session at #GeoLearningForum2021

Can’t remember at what time I had a drink during the night, but judging from the shape of my bottle, it was probably somewhere high up in the mountains!

Good morning, Bergen!

Home is … getting off the night train, sneaking into your friend’s house in the dark, curling up on the couch, and waking up to coffee & bacon & eggs. And then going on a road trip involving at least 3 ferry rides and going back and forth an 8 km tunnel to 260m below sea level just because the bridge before has such pretty views. Thank you for a wonderful day @gloep_

Two sets of wakes and snow on the mountains. What more could anyone ask for?

Wow, what’s going on with these clouds?!

These waves in the clouds are seriously cool

Love this light!

What a cool contrast between the lush grass and the snowy mountains!

Wake watching: nice separation of the turbulent wake where the boat pushed through the water bounded by a little foam, & the V-shaped wake formed of wavelets

Bergen, I will miss you…

Do you see what I see?

#SheLies

Don’t know what it is about #SheLies but I’m fascinated

Getting ready to go hooooooome

Beautiful wakes on #oslofjorden

And this is home #KielerLeuchtturm

Pilot boat on a windy morning!

#LeuchtturmFriedrichsort

#WakeWatching!

Confined to the cabins due to protocols for disembarkment, but looks like we are home ;)

What can I say, except for MOIN Kiel :)

It’s not getting boring, now that I’ve been home for almost 5 hours… @kjersti.daae and I just presented at #issotl!

Good morning!
