I hope you saw my post on the Arnside tidal bore and are well aware of the awesome tides in Morecombe Bay (if not, check it out here!), so here is a little more about them. This is what the bay looked like at the beginning of our picknick. 40 minutes later, see how there […]
Does that warning sign above (that I showed as a teaser in yesterday’s post on wave watching in and around Arnside) make you as curious as it made me? Usually, water rises for approximately 6 hours until high tide is reached, and then falls again for another approximately 6 hours until low tide is reached. […]
Looking at the picture above, taken in the South Walney Island Nature Reserve on our walk yesterday, what is the first thing you notice? For me, it is not the cute little hide which is a perfect spot for seal and bird watching, for me it is — obviously! — what is going on with […]
As you might have noticed, the last couple of days I have been super excited to play with the large tanks at GFI in Bergen. But then there are also simple kitchen oceanography experiments that need doing that you can bring into your class with you, like for example one showing that tides and internal waves […]
Another thing I can’t stop being fascinated by: Tides. Sometimes you look towards Hastings Pier, and there is water all the way up to the sea wall. Those are the times I am too stunned to take pictures, unfortunately. Other times, the sea retreats: Further and further. And then at some point I can’t zoom […]
Disclaimer: This post might well be called “fun with tides” similar to Sheldon Cooper’s “fun with flags” — it is super nerdy, but at least I am having fun! There is some really cool art around Hamburg, and the one I want to talk about today is called “four men on buoys” by Stephan Balkenhol: […]
For most of my readers it might be pretty obvious what the movement of floating ice says about the flow field “below”, but most “normal” people would probably not even notice that there is something to see. So I want to present a couple of pictures and observations today to help you talk to the people around […]
Tides in Cornwall. The other day we talked about a very simplistic models of tides in a glass, and how the high tide and low tide travel as a wave around an ocean basin. This isn’t really a news flash for people reading this blog, I know. But it is sometimes hard to imagine how […]
A first attempt where gravity (due to a tilted axis of rotation) replaces the pull of the moon. (deutscher Text unten) The movie contains both a view from a co-rotating camera and from a non-rotating camera. Gezeiten im rotierenden Tank, in dem die Anziehung durch den Mond durch Erdanziehung simuliert wird, die wir durch eine […]
Watching the strongest tidal current in the world. Together with my friend P, I went to see the strongest tidal current in the world more than two years ago. And it only occurred to me last night that I had not shown you the movies! If you ever find yourself close to Bodø, Norway, you […]
Instruction for a very simple DIY tidal model. Today, we built a very simple DIY tidal model in class. It consists of two sets of tidal bulges: One locked in place relative to the sun on the piece of cardboard that we use as the base, the other one with its very own little moon […]
