Irregular wave ripples, and some left on the beach when the water is gone

mglessmer — Fri, 29 May 2020 12:05:02 +0000

I’m getting more and more fascinated with wave ripples. I kinda understand how they form, but not enough to be able to explain as much about them as I would like to. For example below: Why is the pattern so different where sand has been washed on top of the shallow stones? Yes, the water […]

Reflections in waves

mglessmer — Sun, 05 May 2019 13:05:30 +0000

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, […]

A #friendlywaves from a field trip in a Norwegian fjord

mglessmer — Sat, 04 May 2019 13:05:11 +0000

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 […]

Visiting my friend’s office for some #wavewatching

Since we seem to be on the topic of wake watching these days, here are some pictures I took when visiting my friend Liz at the European Cruise Service’s offices in Bergen the other day. She had already told me about the awesome wave watching to be done from their meeting room, but see for […]

I’m explaining your wave pictures: A #friendlywave from the Île d’Yeu, France

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 […]

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 […]

Visiting the ruins of a wave power plant — waves running up a funnel to fill a reservoir

mglessmer — Thu, 20 Dec 2018 09:36:32 +0000

Using wave energy to generate electricity sounds very attractive, after all there are tons of waves and all they do (in addition to looking pretty) is eroding coast lines. But that’s exactly the problem: There is a lot of energy in waves, so wave power plants have to be extremely tough. Here is another post […]

Visiting the ruins of a wave power plant — waves driving a turbine

mglessmer — Wed, 19 Dec 2018 11:02:24 +0000

After posting about how longer fetch leads to higher waves yesterday, here is why I was in that exact spot in the first place: To visit an old wave power plant on Toftøyna! The power plant was built in the 80s but destroyed only a couple of years after it had been built, so all […]

Same wind, different waves, or: the influence of fetch length on the size of waves

mglessmer — Tue, 18 Dec 2018 09:49:24 +0000

I just found this picture that I took back in May near my friend Elin’s cabin on an island in western Norway, and it’s a really nice illustration of how the same wind will cause very different waves depending on whether it’s blowing over the sea for many kilometres, or over a puddle for only […]
