The Calypso corer is bent. It is not supposed to look like this. We try to avoid these bananas, but sometimes we just hit a piece of ocean floor that is much harder than we interpret it to be. Luckily our crew can fix a million problems. Photo: Jochen Knies

Chief Scientist’s Diary: Jochen Knies

October 26, 2019: Bend it like Beckham.

Well, things can go terribly wrong during an Arctic Expedition. Always expect the unexpected. We bend the Calypso Giant Piston corer on the first station on the Vestnesa Ridge, Northwest of Svalbard. We thought we had control of the sediments we were supposed to core. ( This is why a good geophysical survey is important!) Unfortunately the core came up on deck with an angle of more than 40 degrees. The good thing though: we saved 6 meter of core material, which will hopefully provide us with an explanation as to why this happened. A big applause to the crew  onboard of RV “Kronprins Haakon” who saved our core material. We have learned a lesson and will shorten the piston core from ~25 m down to ~15 m, at least for the Vestnesa Ridge. Honestly, I would appreciate ONE boring day without any surprises. Just ordinary nine-to-five, you know. However, the crew feels otherwise. The reason that they love their job. is because something unexpected is bound to happen.  We will see what’s surprises are coming next.
