One might ask oneself why we are insisting on rotating tank experiments. In order to establish that rotation isn’t just there to make equations a lot more complicated, but that it actually changes how things behave, we ran two different experiments. Turbulence in rotating and non-rotating system First the probably easiest experiment anyone could imagine: […]
Yesterday Torge and I spent a fun Friday night trying out new rotating tank experiments together with Rolf Käse. Rolf taught the lab course that got me into tank experiments (back in 2004!) and he’s still such a huge inspiration! Rolf brought his tank which features a conical bottom, and this gives so many more […]
(English below) Am 23.11. sind wir planmäßig aus Mindelo ausgelaufen. Die ersten Tage auf See waren sehr arbeitsintensiv. Alle Geräte an Bord mussten vorbereitet werden und die Routine an Bord musste sich einspielen. Währenddessen werten Kollegen in Kiel und am HZG Satellitenbilder aus der Region aus und erstellen Computersimulationen der Wirbelbewegungen. Zusammen mit den Echtzeitdaten […]
Auf Reisen gibt es nichts Besseres, als die lokalen Gerichte zu probieren. Es geht oft um mehr als nur eine Mahlzeit, es geht auch darum eine Kultur zu erleben. An Bord der M159 gaben Mike und Rainer uns diese unglaubliche Erfahrung. Jeden Tag entdeckten wir Deutschland und andere Länder. Sie haben uns von Hamburg nach […]
When travelling, there is nothing better than tasting the local food. It is often more than just a meal, it is also about experiencing a culture. On board of the M159, Mike and Rainer gave us that incredible experience. Every single day, we discovered Germany and other countries. They have transported us from Hamburg to […]
For 21 days, the Meteor has passed through the waters of the Atlantic Ocean. Starting our expedition M159 in the southern hemisphere in Recife, Brazil, we worked our way northward to a ship position close to the Cap Verde Islands, where we are about to collect our last mooring for this cruise – the Cape […]
(English version below) Langsam wird es spannend. Forscherinnen und Forscher aus Kiel, Geesthacht, Kaiserslautern, Bremen, Aachen sowie von den kapverdischen Inseln legen derzeit im tropischen Nordostatlantik ihre Daten-Netze aus. Netze, in denen sie einen Eddy fangen wollen. Am besten sogar mehrere. Eddy? Wer – oder was – ist das eigentlich? Also, bevor wir die Jagd […]
I like making photographs of mountains. Mostly because of the sheer beauty of them, but also because the process to do so is particularly simple and yet it generally makes for splendid pictures: first one has to climb another neighbouring mountain, then one has to point the camera in the general direction of the first […]
The R/V Meteor has a meteorological station from the German Weather Service (Deutscher Wetterdienst, DWD) and a technician to operate it on board. In 1964, the previous Meteor was the first research vessel with a meteorological station operated by the DWD. When the ship was replaced by the current Meteor in 1986, a meteorological station […]
What is the base of life in the open sea? This is a very complex question, because many factors and forces are at work in the high sea. But let’s start somewhere, maybe with the water itself… Upwelling regions are, in simple terms, a convergence of deep ocean currents bringing cold water, rich in nutrients, to the […]
