That’s a great question, Sophia! And one that is really difficult to answer. But I’ll try!

Or: How does momentum get transferred from a rotating tank to the water? I recently noticed — and it was confirmed by observations and student feedback that my friend Kjersti got — that it is not at all obvious to students how momentum gets transferred from a rotating tank into the water. For me, the […]

It doesn’t feel like it, but today marks the 7-year-anniversary of my first blog post on my “Adventures in Oceanography and Teaching”! To celebrate, I sent out this call to action (and please feel free to respond, no matter when you are reading this): Below, I am sharing the pictures that people sent me plus […]

Florian sent me a #friendlywave — a wave picture he took, with hopes that I might be able to explain what is going on there. And this one had me puzzled for some time! This is what the picture looks like: What I knew about it: Florian was on the ferry from Wisschafen to Glückstadt, crossing the […]

My long time Twitter friend Anne shared these beautiful pictures and I absolutely had to do a #friendlywaves post where I explain other people’s wave pictures. Take a moment to admire the beautiful picture below. Wouldn’t you love to be there? I certainly would! What can we learn from this picture? First — it’s a windy […]

A #friendlywaves post: you send me the pictures, I talk about physics! Today: My friend A sent me these lovely pictures from Lofoten, knowing I love wave watching. And there is so much to see! Let’s begin with the picture above, where we are looking out over the stern of a ship towards a bridge. There […]

A reader of my blog, Rocío*, sent me this beautiful image from Arnao beach (Castrillón- Asturias-Spain), and I asked if I could use it in a #friendlywaves post. He agreed, so here we go! First, let’s check out the original image in all its beauty, before I start scribbling on it. What features of the waves […]

Christina writes on Twitter: “#wavewatching from a plane, approaching #Panama. @Meermini, do you know what causes those regular ‘wrinkles’?” and how could I resist writing a blog post about what I think might be the explanation? Below is the picture Christina shared on Twitter. What I think we see here are basically two wave fields: […]

Do you like observing wave fields and pondering what might have caused them? Why they look the way they do? What caused them? What they can tell us about the wind, the sea floor, the trajectory of a ship? This is actually not an easy task and takes a lot of practice and a good understanding […]

Astrid, #wavewatching supporter from Day 1, sent me these pictures for a #friendlywaves post. Today, I want to start with a spoiler picture (or, rather, I did start with a spoiler picture already — see above) that shows you the setting at low tide to help us explain the wave pattern that we then observe […]

Anyone who might be new to my blog because of yesterday’s presentation at #SiPManc — please don’t be scared and run away, this is the most complicated #friendlywaves I have ever gotten, usually things are A LOT easier! :-) I love #friendlywaves! Victor sent me the picture above. He took it in 2017 in Tampa, […]

My friend Alice is currently in Berlin, and as one does when visiting Germany’s capital city: She’s wave watching! I can only say: I approve! That’s what I always do there, too (exhibit 1, exhibit 2). And knowing that I always like the challenge, she sent me a #friendlywaves picture. Meaning a picture of waves […]

This is a #friendlywaves challenge, where I try to explain other people’s wave photos and they tell me how I did. I love it when my friends see waves, think of me, whip out their cameras, take pictures, and send them to me! In this case, Nena even used a telephoto lens and took the […]

My friend Alice (of the awesome Instagram @scied_alice and the equally awesome blog, which you should totally follow) sent me a #friendlywaves from her trip to Cyprus. She said that this was a simple one, so I am looking forward to what else she has up her sleeve once I pass this test ;-) So here we go […]

A beautiful picture: the pink sky, purple clouds, a peaceful channel flowing in between lush greens that the calm water surface mirrors back, a bridge somewhere in the background, connecting the shores, both in reality and in the image on the water. Early morning harmony. Hygge? And what jumps at me? Waves! Which I think […]

After doing a #friendlywaves post from a Norwegian fjord yesterday, let’s do another one from somewhere south of Bergen, by my friend Arnt. Very different mood today! What I find super fascinating about the picture below is how clearly you see the ship’s feathery wake in the reflection of the street lamps on the bridge, […]

The other day, my friend and co-author Pierré sent me pictures he took during fieldwork in a Norwegian fjord. As I, sadly, wasn’t there, all I can do now is admire the pictures and wish I had been there. And, of course, do a #friendlywaves — an interpretation of a wave field that a friend […]

The whole #friendlywave thing (where I explain your wave picture) is starting off great! Here is one that reached my via my Twitter; link to thread here. What’s going on in the north east of Île d’Yeu, France? Here are four pictures from the Twitter thread that got me intrigued: Because of the awesome waves […]

#friendlywave is the new hashtag I am currently establishing. Send me your picture of waves, I will do my best to explain what’s going on there! When it rains, it pours, especially in LA. So much so that they have flood control channels running throughout the city even though they are only needed a couple of […]

Recently, more and more of my friends send me pictures of waves they spotted when walking along a lake side or taking a ferry ride. I love how contagious wave watching is, and I love sharing my fascination with you! :-) Here are some pictures that Fred sent me of his lovely Sunday walk today. There […]

“Hei Mirjam. Bergen had it’s two days of allocated summer during the weekend of 22 – 23 July 2017 and Elsa and I decided to – in true Norwegian style – take advantage of the rare occasion and go for a hike. A colleague of mine has a “hytte” near Langhelle and had invited us […]
