Sightseeing in Berlin? Any excuse for a #wavewatching trip!

Berlin is full of interesting history to discover … for example that of ships that have gone past on the Spree! :-D

Let’s start with some easy wave watching. In the picture above, you see a ship and its wake (both parts: the turbulent one where the ship has gone, and the feathery wake that forms the V with the ship at its tip). And you can make out the wake of a ship that has already gone round that bend of the Spree: the turbulent part showing a different surface roughness, and reflected remains of the feathery V on the right shore of the Spree. So far, so good!

Below, you see two turbulent wakes: The one of the ship you still see, and then the one of a ship that went the other way, but already went out of the area captured in the picture.

And here is a series where you see the feathery wake reach the side of the Spree…

…get reflected there…

…and then meet the reflection of the other side of the V to form a checkerboard pattern! Would you have known what’s going on here if you hadn’t spotted the ship just about to leave the picture, or seen the previous images?

Below is another nice one. What happened here? A ship sat there, waiting, and then started moving again right before I took the picture! This is the beginning of a turbulent wake right here.

And below another nice wake plus reflection.

And here you see another feathery wake, plus the turbulent wake of the same ship on the other side of the Spree.

Similar picture as above, except in a different spot…

Yes, that’s a pretty good representation of what sightseeing trips with me are like ;-)
