reflections – Adventures in Oceanography and Teaching

Fun #WaveWatching today! Reflections all the way….and then the boundary suddenly ends!

You might remember this edge here and the reflection situation. More details in this recent post, but in a nutshell: The wave crests marked in red are approaching the beach and wooden edge, and where they hit the wooden edge, they get reflected and converted into the green wave crests which propagate away from the […]

When you meet a hard boundary, the reflection starts

When I look at the picture above, I see basically three different zones on the surface of the lake. The yellow zone, which is under the direct influence of the wind, where the water is full of small waves, and then two other zones. In the red zone, the water isn’t under direct influence of […]

Lille Lungegårdsvannet

The geometric shape of Lille Lungegårdsvannet makes for perfect wave watching conditions. Not only when wanting to look at waves from all sides, but also when you are just fascinated by reflections and geometric wave pattern. And also by rainbows. Am I the only one who, when the sun is out and at a good […]

Bergen harbour wave watching

mglessmer — Fri, 20 Sep 2019 05:06:21 +0000

Oh look, someone built a perfect rectangular wave watching basin into Bergen harbour! As you see above, waves are propagating towards this little wave tank and into it. They then get reflected at the edge at the bottom of the picture. Then, the original incoming wave and reflection propagate together further into the basin. They […]

A #friendlywaves from Tampa, Florida

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, […]

Determining the slope of sea surface via the reflection of a structure

(Disclaimer: The physics the title refers to are somewhere in the second half of the blog post when I am done rambling) In case you are wondering why I am blogging so much all of a sudden: Sometimes I just love to spend a couple of hours on my sofa, drink something warm, and play […]

Early morning wave watching. Nothing quite like it :-)

mglessmer — Wed, 17 Apr 2019 05:35:17 +0000

Occasionally working from home is awesome for many reasons, but mainly because I can use the time usually spent on commuting on … wait for it … wave watching. With my cup of coffee so I can warm up my fingers in between taking tons of pictures. But I just love it. See below how […]

Commissioned wave watching: Eckernförde edition on a beautiful calm and sunny Sunday!

mglessmer — Sun, 20 Jan 2019 14:47:22 +0000

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 […]

Forget about big waves, today we are focussing on the details!

mglessmer — Tue, 15 Jan 2019 15:30:23 +0000

Today we are focussing on tiny waves right near the shore inside the sheltered harbor. See how below there are two wave fields, one with longer waves with crests that are parallel to the water’s edge, and then shorter ones propagating at a right angle relative to the first field? Where the rope swims on […]

Wave reflections

This still is one of my favourite kinds of wave field to look at. So calming. (Who am I kidding. All waves are my favourite waves, of course! I am addicted to wave watching…) Here is a short movie for you where you see the crests coming in from the bottom right and then being […]
