Harvesting

Earthquake waves generated by the Sept 9, 2017 Mexiko earthquake (magnitude 8.2). The waves travel through the earth, similar to a medical computer tomography. We use these data to reconstruct the inner structure of our planet.

During our last days here in our working area we are shifting it into gear, because it is harvesting time! Finally we will have a look at our data coming back from the sea floor – we all have been waiting for this very moment since weeks now (and some of us since a few […]

On the edge

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). […]

Wie viel Mikroplastik ist an unseren Stränden?

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 […]

GAME 2018: Grazing in a warmer ocean revisited – will marine invertebrates change their food preferences?

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 […]

To fish in muddy waters…

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 […]

Ocean bottom What??

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 […]

EN ROUTE !

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 […]
