For #CTDAppreciationDay, I am re-sharing a video that Sindre Skrede (find him on twitter or vimeo for many more exciting pictures and movies!) and I made in 2011 (!!).
I am still super proud of this work because I first narrated it in Norwegian (after only having lived in Norway for a couple of months and having started classes only after moving there! Scary stuff, but I did it!), and we only translated it to English afterwards. Also I think we did a great job there!
Reposting from Elin’s blog:
Kjersti, Steffi, Elin and myself (Mirjam) recently discussed ways to better integrate the GEOF105 student cruise into the course. My suggestion was to ask the students to observe things throughout the whole duration of the course, and then have them relate their time series with what they observe when “at sea”. In this mini series tagged #BergenWaveWatching, I write up a couple of suggestions I have for observations that are easy and fun to make. I am anticipating that my suggestions will be strongly biased towards #wavewatching, so if you have any other suggestions, I am all ears! :-)
Where to go
Anywhere where you can look out over water, for example Fjellveien (where the picture above was taken from) or Fløyen
When to go
Any time
What to look out for
Pattern on the water. Can you see wakes? Langmuir circulation? Gusts of wind? Areas that are sheltered from the wind?
Langmuir circulation in Østerfjorden, described here.
What to do with the data
Observe closely and try to make sense of it by relating it to, for example, ships, weather at that time, …
Do you have suggestions for us? What other spots or topics would you recommend in and around Bergen to be added to the #BergenWaveWatching list? Please leave a comment! We are always looking to expand this list!
“I don’t want my face on the internet!”, “My science should speak for itself, it shouldn’t matter who I am as a person!”, “I just don’t like what I look like in pictures!”, “People won’t perceive me as professional when I include selfies in my science communication work!”: There are many reasons for not posting selfies on the internet, and I sympathise with many of them. However, I have chosen (and continue to choose) to post the occasional selfie. Why is that?
My main goal I am trying to achieve with my scicomm Instagram @fascinocean_kiel is to show that exciting science (specifically ocean physics) can be discovered EVERYWHERE if you are open to seeing it. This means that I post pictures of water that I take on walks along any kind of river, lake, ocean, but also in puddles, sinks, or tea cups, pretty much daily.
But in order to make my Insta relatable to other people, I find it important to put these pictures in the context of my life. Yes, I live on the Baltic Sea coast and therefore have the opportunity to see “the ocean” (well, kinda) on an almost daily basis, which is reflected in my Insta. But I commute to work in Hamburg (where I see Elbe river and the Port of Hamburg, which you also see quite a lot), and I travel a lot throughout Germany and beyond. Some days I’m on the train — on those days you’ll often see pictures of water taken from the train window. Or if I am giving workshops in locations with fancy taps, you will see those. My point is: You can discover oceanography everywhere. If you choose to look for it.
But then who does get this excited about this kind of stuff? Well, I do. And this is where #ThisIsWhatAScientistLooksLike comes in. I’m not wearing a lab coat, and I am not even observing this science as part of my job. I’m not even employed as a scientist any more, nor do I want to be. But I didn’t loose my identity as a scientist when I decided to stop pursuing an academic career. That was a huge fear I had when I was in the process of wanting out of academia — that I would be a failed scientist if I left, even if I left because I would rather be somewhere else. So for me, showing that I am still a scientist even if that’s not my day job anymore is my way of offering myself as the role model that I wish I had during that time, showing that leaving academia doesn’t make you any less of a scientist.
Of course, #ThisIsWhatAScientistLooksLike also includes other aspects, for example making women or other minorities in science more visible. Or showing that there is no one “correct” way of being a scientist. For example the clothes you wear or how much effort you put into looking put together are in no way correlated to how serious you are about your science. Contributing to spreading that message is a nice side effect for me.
But does posting selfies do anything to how people perceive scientists?
There is a 2019 study by Jarreau et al. that looked at this. They compared different kinds of Instagram posts, some showing selfies of scientists, some showing only lab equipment or other pictures of the work only. And they found that posting selfies does actually have an impact on how scientists are perceived.
Scientists posting selfies (as opposed to those only posting “work stuff”) were perceived as significantly warmer. Appearing warm is definitely desirable in this context, as warmth is a component of trustworthiness. Obviously, as a scientist we want to be, but also be perceived as, trustworthy. This perception is created in this study when selfies were used.
Another finding is that posting selfies does not result in scientists being perceived as less competent, both for male and female scientists. So here goes the fear mentioned above that posting selfies will make you appear less serious about your work! Or does it? Note that of course this study does not guarantee that nobody ever will think less of you because you are posting selfies. Of course there might be people you are working with, or more generally, that see your selfies online and think any number of weird things. In general, this does not appear to be the case. But you know your bosses, your community, your life best, so ultimately if this is a concern you have, you need to weigh the potential benefits of posting selfies against that risk. In my case, I have decided that I can totally live with what some people might think about me posting selfies because I know that the people who matter to me don’t think less of me because of it. Additionally, I have gotten a lot of feedback that people actually enjoy seeing selfies on my Insta occasionally, because it does make it more relatable.
As a women, I also find it important that I post selfies, because the study showed that this can contribute to making science be perceived less as “exclusively male”. The common stereotype of what a scientist looks like is still to this day an old white male (in a lab coat and with messy hair). Of course there are plenty of those around, but there are so many brilliant and inspiring women out there, too, that I’d like to see that stereotype change.
In total, results of the study are that showing selfies can potentially help change attitudes towards scientists towards the better. The study doesn’t explore the mechanisms through which this happens (so it might depend on, for example, facial expressions, features of the background, or tons of other things), so it is by no means guaranteed to work for every selfie being posted on the internet (and also how many selfies do people need to see for this effect to kick in, or what does the ratio to “science stuff only” pictures need to be? And how long does the effect last?). In any case, to me, this study is indication enough that me posting selfies might have all the intended consequences, and that’s reason enough for me to choose to post selfies. And I encourage you to check out the study and consider posting selfies, too!
P.S.: This picture is clearly not a selfie, it was taken by my brilliant colleague Sebi Berens (www.sebiberensphoto.com / @sebiberensphoto). Thank you, Sebi!

Yesterday, we’ve had four rotating tables operating simultaneously, for three different experiments. The one that everybody is gathering around in the picture above is our favourite experiment: a slowly rotating tank with cooling in the middle that shows a nice 2D circulation instead of an overturning as we would expect in a non-rotating system.
A second group was doing an Ekman spiral experiment similar to this one.
If you are interested in observing the bottom boundary layer of a tank, it might look a bit weird to people who don’t know what you are up to…
And the other two experiments were the planetary Rossby wave experiments that I’ve written about so much before that it doesn’t really matter that I didn’t take any pictures this time round.
Yay! Another recap of my wave watching Insta!
The year started off in the very best company — watching ships and waves and flowers with Astrid!
But of course there is also actual wave watching happening: Here we see a ship’s wake arriving. I find it fascinating how there are the stripes where you can look into the water and then those where you can’t! Total reflection in action. When I learned about that in physics class I never thought that was a phenomenon I would ever see in real life!
When the waves from the picture above meet the curved sea wall, they get reflected into this pretty pattern.
Another day, foggy and very windy! That day, my focus was on how there are no waves in the lee obstacles. Only after sufficiently long fetch do waves start to grow.
See how the surface roughness changes with distance from the obstacle?
Oh, and then there was a sunny day! The Oslo ferry is leaving in the distance. See the stripes in different blue tones? In the foreground you can see how the colors are related to surface roughness. Areas that are more exposed to wind are rougher with more waves and different wavelengths, and look darker. More sheltered areas in the lee of structures have fewer waves and appear in a lighter blue.
Oh, and then I had a great day with my nephew in the port of Hamburg with harbour boat trips, walks on the beach, and tons of wave watching. He was very impressed by my skill to know how far each wave would run up the beach, especially since we saw lots of people who either ran away screaming or got wet feet :-D
Another picture from the same day with my nephew: Here is a wave train from a ship’s wake arriving at the beach. I love watching this kind of stuff!
And then one day, I went#WakeWatching! On all three pictures below, you see waves made by the same little ferry. On the right is the turbulent wake where the ship just moved through the water, and on the left some of the feathers that form the V.
Here the ship is turning so we see water that is disturbed by the ship moving through, but doesn’t have the „boiling“ like where the propeller stirred up everything.
Now we see how the wind waves seem to be bunching up at the boundary between the wake and the area that wasn’t affected by the ship moving through.
Then, for #SciCommSunday, I posted a picture of a book that I think is a brilliant introduction to the science of communicating science that I also wrote a blogpost on.
And surprise: Bonus pic for my dear readers that I didn’t post on Instagram but that I think is cool (will definitely experiment with this kind of pictures more! Except panorama mode does weird things to waves, so on second thought maybe not…)
What we are looking at in the picture above is a really low-water day in Kiel. Which leads to interesting wave watching opportunities!
See how waves that arrive with straight crests somewhere offshore get bent as they reach the shallow water? That’s because the velocity of a wave depends on water depth. The deeper the water, the faster the wave can move. The shallower the water, the more the wave is slowed down. Therefore, waves get slowed down first in regions where the water is shallower, and the parts of the wave crest that are still in deeper water wrap around the shallower part. Kinda like when you are slipping on an icy road, you fall in the direction of the foot that didn’t slip because your body spins in that direction.
When there is really low water in Kiel fjord, we can observe the influence of topography on waves much better than we usually can! For example here we see how on one part of the “beach”, there are several wave crests behind each other, all breaking, whereas on the other part on the other side of the headland there is only one wave crest at the water’s edge. Why is that?
Wave crests get steeper and start to break when the water is shallow enough for the wave to “feel” the bottom. On the left side of the picture, depth is increasing faster towards the open ocean: The wave only feels the bottom right before it has reached the water’s edge. On the right side of the picture, on the other hand, the depth changes very gradually. Therefore waves feel the bottom already much earlier and many wave crests are steepening, preparing to break and finally breaking at the same time.
And then I just thought this picture was fun :-)
And a rainy day at work!
I actually don’t mind all the rain: It makes the flow in all the storm drains so much more interesting! Here we see how water shoots out of a pipe into a little lake. Note that I’m saying the water is shooting rather than flowing: That means that it is moving so fast that any disturbance is washed away with the water.
As the water shoots into the much slower flowing lake, it pulls water from the sides with it. This water obviously needs to be replaced from further away, so a recirculation is set up.
Here is an annotated version of the picture to see the recirculation going on:
So that’s what has been going on over on my wave watching Insta @fascinocean_kiel! :-)

I strongly believe that all scicomm efforts should be grounded in the science of science communication. That means reading a lot of original literature, or … reading this book that I recently found. It’s a quick and fun overview over the current understanding of what works and why: “The Science of Communicating Science — The Ultimate Guide” by Craig Cormick.
The book is structured in four parts: “The ground rules”, “communication tools”, “when things get hard”, and “science communication issues”. It is a really easy and enjoyable read. It’s full of funny stories and cute sketches that illustrate key concepts, and despite it being pretty much a review of the relevant literature, it’s written in a conversational style. The author brings in a lot of stories that make his points. For example to stress the importance of story telling, he talks about how every last tired student woke up in a lecture once he paused his usual lecturing and said “let me tell you a story!”. Very relatable.
This part provides a lot of the background knowledge on scicomm. Why do we need to communicate science? What makes science communication good science communication? What is it that the public knows and believes about science, and how much do they care about science? And is there even such a thing as “the public”? (Spoiler alert: of course not!)
It for example tackles one of the big problems I see in science communication: People believing that they will change other people’s minds with more information (and, it’s quite interesting that in my experience, those people’s minds usually aren’t changed by all the data that contradicts them on that).
This part of the book should definitely be required reading for anyone doing scicomm.
In this part, the author deals with many different ways to communicate with audiences, and what is known about them — both the communication tools themselves and what audiences might be reached with which tool. For example for social media, it is important to understand who for example has internet access and who is actually using what channel for what purpose, in order to find the best way to reach your specific audience. Or for TED talks, turns out that the gestures and way you present yourself are super important for how you are being perceived so that it basically doesn’t matter to the ratings whether people watch you with sound on or off. How scary is this?
This part of the book is definitely interesting to browse for an overview over many different tools, and looking at chances and challenges of each. And if you are planning to use, or already using, any of the tools described there, it will be super helpful to look into what the author has to say about it.
Now we are getting into the really difficult issues, like for example beliefs. Why do people believe what they believe? And how can we respectfully and constructively deal with people who hold beliefs different from ours? (How) can we change beliefs?
Or another example that I found really interesting because I hadn’t thought about it before, or at least not in those terms, was communicating risk. For risk communication, there are different strategies recommended for audiences that are defined depending on how much they are concerned about a specific risk on the one hand, and how much they are affected by that risk on the other. People in the low concern & low affected corner are an audience that can be communicated with in the way you would normally do scicomm. However, as soon as there is high concern or high risk, things change. For audiences that are highly concerned despite not being highly affected, listening is the key, both to make them feel understood as well as to understand what exactly their concerns are so that you can eventually help them see that despite the concerns they might not be as much as risk as they think they are. But then for people with low levels of concerns but high risk, a completely different approach is needed, one that educates people about the risks they are at. Lastly, people who are both highly concerned and highly at risk are the group that you need to engage with the most. And there are a lot of pointers for how to do that in the book, that I can’t all spill here ;-)
Another chapter in this part of the book that I found really interesting is on changing people’s behaviours. In a nutshell, you don’t change people’s behaviours by changing what they think they should be doing, you change behaviours first and that will lead to a change in attitudes towards the behaviour they are now employing. It’s all about cognitive dissonance and how we are trying to avoid a mismatch between what we say we want to do and what we actually do — usually by changing our attitudes, not our behaviours. So make it easy for people to behave in the way you want them to behave and their attitudes will follow (one of the reasons why I think taxing and fines as tools to influence behaviours should be used a lot more; attitudes will follow…).
This part of the book then concludes with chapters on “communicating controversies” (lots of helpful strategies for if/when you get caught in a shit storm!) and “debunking bunkum” about dealing with pseudoscience.
I really loved this part of the book, because here issues get addressed that we don’t talk about enough, like ethics of scicomm. When we talk about “what works in scicomm”, in a way it’s fair to say that we are talking about ways of manipulating people. We do this with the best intentions, but still, we are basically employing and sharing techniques to make people believe what we believe and act in ways that we think are the right ones. And once in a while it’s good to stop and think about what exactly it is that we are doing there and if we want to adopt existing or develop new guidelines or a code of conduct.
Then there is a chapter on all the caveats of scicomm research. How valid is all the stuff that we think we know about how scicomm works? Very important read!
And lastly, the author ends with an appeal to scicomm researchers to make their findings accessible to practitioners, and for practitioners to dig around if there might already be research available on their formats and topics. To sum it up: “Go and do brilliant things”!
In my old job in scicomm research, I had the time to read a lot of scientific articles as well as reports, blog posts, etc, and go to workshops, watch youtube, browse social media, etc, to inform myself about the cutting edge science and practice of scicomm. And that’s pretty much a full-time job. Now, with my current job, I still try to keep up to date, but I am really glad I have this foundation of two years full-time focus on scicomm research & practice to fall back on. So I am very much aware of how much there is to learn about scicomm, and how difficult it is to do when that isn’t your primary focus.
I received this book last year, two days before giving an introductory scicomm workshop, and binge-read it to make sure I wasn’t missing anything super important in my workshop. Turns out that the first part of this book, “the ground rules”, is a very good match with what I chose to include as a foundation for my workshop, citing many of the same articles and focusing on very similar topics. If you can’t spend a huge amount of time on diving into the science of scicomm (or attend one of my workshops, obviously ;-)), reading this book is really the best way to get started that I am aware of, and I highly highly recommend reading it! And even if you think you know all there is to know, it’s really refreshing to get a new perspective on things. Still go read the book! :-)
P.S.: A quick overview over the main message of the book (and including some of the fun sketches!) is also given here, by the author himself. So go check that out, too!
P.P.S.: Looking for more to read? Another book I liked a lot and recommended on here about a year ago (when it had just come out): Communicating Climate Change by Armstrong, Krasny & Schuldt.
“The Science of Communicating Science — The Ultimate Guide” by C. Cormick (2019).
“Communicating Climate Change” by A. K. Armstrong, M. E. Krasny, J. P. Schuldt (2018).
In addition to our four DIYnamics-inspired rotating tanks, we now have a highly professional rotating table with SO MANY options! And also so much unboxing and constructing and trouble-shooting to do before it works. But we finished the first successful test: wanna see some rotating coffee in which milk is added? Then check this out!
Luckily Torge is patient enough to deal with me bossing him around, but it took forever to get the whole thing to work and I wanted my movie ;-)
Before we got to that point, though, did I mention that we had a lot of unboxing and constructing to do? But it was a bit like Christmas… And I can’t wait to play with every last piece of equipment! So many new and fun options for experiments I’ve always been wanting to do!
Happy #FlumeFriday! :-)

Where to go
We spotted standing waves in a bucket on the latest GEOF105 student cruise, but in addition to on ships, they can also be spotted for example on trains (see pic below), in cars, or even on washing machines.
What to look out for
The pattern that form on the surface of vibrating fluids
What to do with the data
Describe the pattern and try to understand why it looks the way it does (like I did here). Is it the frequency of vibration? The shape of the vessel? The material of the vessel? The location relative to the source of vibration?
Do you have suggestions for us? What other spots or topics would you recommend in and around Bergen to be added to the #BergenWaveWatching list? Please leave a comment! We are always looking to expand this list!

Where to go
Bølgekraftverket in Øygården
When to go
Until recently I would have said that it doesn’t really matter when you are going, because whenever I had been there I got to see things like this:
But then I went there and there were absolutely no waves to be seen, which I think was a combination of a calm day with hardly any wind, no swell coming in either, and very low water levels, possibly tides and in general. So I would recommend going there when there is wind and also the water levels aren’t super low so any potential waves actually have the chance to make it into the area of the wave power plant.
Unusually calm day at the wave power plant. See the pillars that used to carry a bridge across here?
A one-off visit on a wavy day should give you plenty of things to discover and think about, but you might get addicted and come back again ;-)
What to look out for
There are at least two parts of the wave power plant where you can clearly recognize how they were supposed to work when they were still in operation. A wave power plant where waves used to drive a turbine, and another one where waves run up a funnel to fill a reservoir. But in general it’s a pretty awesome wave watching spots with some rocks that are usually just below or at water level, steep cliffs, areas that are exposed to the open ocean while others are sheltered from the waves and wind. So much to explore!
What to do with the data
“Data” here means your pics and movies of the waves.
I find it super interesting to just describe the observations of the waves around the island and wave power plant, and it might keep you busy for a while (see for example the two blog posts I linked to in the paragraph above). But you could of course also look into wave conditions in this spot. What does the wave forecast say for the day you are visiting? How do the wave conditions on that day compare to the average conditions? Or the day when the power plant got destroyed? Or the most recent extreme events? How often do extreme events occur? And what conditions actually make an event “extreme” in this place?
How this is relevant for the student cruise
Understanding waves and their enormous forces is relevant for anyone who wants to work with ocean observations or any kind of structures in the ocean. This is the ideal spot to become aware of how fragile any human structure is when confronted with the forces of nature. Also looking at wave fields more closely, both in observations and in models, is a great way to connect to what’s really going on in the ocean.
