An expedition can never be fully planned in advance. At sea, everything can evolve differently every day, every hour. So was the case for this trip. The drifter, which was supposed to be followed until the 7th of February, left the upwelling patch and was heading at high speed to the south. As a result, […]
The week is starting onboard POSEIDON. Slowly the sun rises, immersing the sea for a brief moment in orange-red light. Eight o’clock. The work on the deck and in the laboratories is going on. The day begins with the measurement of the microstructure sonde, followed by the CTD. In addition to this station work, so-called […]
A focus of this trip is on the drifter, which tracks the course of an upwelled water patch of deep water. After we deployed the drifter on January 27, we followed it for several days. We also surveyed the area around the drifter by doing east-west and north-south sections, always returning to the drifter. On […]
Three times a day, water samples are taken on the R/V POSEIDON using the CTD rosette. CTD stands for conductivity, temperature, and depth, which is determined by measuring the pressure. CTD sampling provides a vertical profile of the water and brings water from different depths to the surface. The CTD rosette on board consists of […]
What is the nature of your work? I am a marine biologist, a benthologist and the centre of my research area is the northern communities, plants, animals, and everything connected with them in marine environments. Since in nature everything is interconnected, I have had the change to study sediments, chemistry, plankton communities and also fish. […]
Liebe Kollegen, Freunde, Familie und Interessierte, Unsere Expedition neigt sich dem Ende zu. Nach 30 Tagen im Arbeitsgebiet haben wir am 27. Januar um 16 Uhr nach Norden in Richtung Las Palmas de Gran Canaria abgedreht und den rund 1.300 Seemeilen langen Rücktransit angetreten. Nach nun abgeschlossener Forschungsarbeit hier einige Zahlen und Fakten zu unseren […]
Saturday, the 27th of January 2018. Today we finally launched the drifter. In the last days we searched for a suitable upwelling-patch off the coast of Mauritania. The drifter has been prepared until late in the night. In the morning, we came closer to the final point of deployment, an area with a fresh upwelling-patch, […]
In the early morning of the 23th of January 2018 the R/V POEIDON left Las Palmas and sailed in the following two days to the coast of Mauritania. During the transit the scientists set up their labs, took initial test measurements and checked the functionality of all their equipment for the upcoming research. Using satellite […]
Archäologe Florian Huber faszinierte Kinder und ihre Eltern bei der Kinderuniversität mit Schilderungen seiner Forschungstauchgänge. Mein zweiter Tag im Exzellenzcluster Future Ocean und es geht sofort richtig zur Sache. Schüler, die ihre Eltern am Ärmel hinter sich herziehen, volle Eingänge ins Audimax und gespannte Stille, als es auf der Bühne losgeht mit der Vorlesung „Versunkene […]
Las Palmas. Yesterday we started the setup for the upcoming expedition on board the POSEIDON. Almost all of the equipment arrived with the ship in a container, which had to be emptied upon arrival. With all equipment on deck, the setup in the different labs and on deck could start. Melf installed a mast on […]
