In our last blog entries we have already reported on our gear and how difficult recovery can be at times. Today, we would like to share some of the daily working life of the scientists here on board with you. Marine geophysical surveys commonly require a large number of helping hands (and brains, of course). […]
Das Thema Mikroplastik ist derzeit in aller Munde. Fast jeder hat schon von diesen Teilchen gehört, die man kaum sehen kann und die doch anscheinend überall sind: In unserer Zahncreme, in unserem Duschgel, möglicherweise auch in unserer Nahrung, vor allem aber in unserer Umwelt. Die Sorge um die Folgen dieser Verschmutzung umtreibt viele Menschen, und […]
(Deutsche Version unten) Between the 14 Feb and 1 March 2018 expedition POS520 with RV POSEIDON and the submersible JAGO takes place off the coast of the cape verde island Santo Antão. The chief scientist, the JAGO team and participants of the cruise write here as guest writers. Today Henk-Jan Hoving, GEOMAR, Deep Sea Biologist, […]
In the last GAME project, the student teams found experimental evidence for the assumption that consumption rates of herbivorous invertebrates will increase when the ocean gets warmer. However, their experiment was (like all experiments) somehow limited, since they offered their test animals a mono-diet that did not give them the chance to change their food […]
Doing science at sea has its very own rules – just like the German soccer cup or DFB-Pokal, for which the saying goes: The cup makes its own rules. The teams dedicate many months to a thorough preparation, all options are evaluated, everything is double-checked, every tactical variation is considered and at the end everything […]
If you want to get an image of the Alps, you need seismometers surrounding the area. But how do you get the seismometers to work at the bottom of the sea? And how do you get them back? To explain this, we invite you to a virtual journey on board of the research vessel Maria […]
Finally, here is the english version of the science comic developed in cooperation with the scientist Dr. Lucia Pita and the science illustrator Dr. Susanne Landis, Scienstration. If the font is too small to read on the screen: simply zoom in on the image with the key combination “ctrl” and “+”. Keep your eyes peeled […]
With a few hours delay we left the port of Las Palmas on Gran Canaria to sail to the Ligurian Sea. The start of MSM 71 indeed proved stormy: The Atlantic waters greeted us with winds of 7 Bft and gales of up to 10 Bft with waves of 6 m height. Nonetheless, everybody on […]
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 […]
