Sampling for biogeochemistry of the surface ocean

Several of our posts mentioned the GoFlo bottles that we use to sample the ocean water. Those sampling bottles are specifically designed for trace metal research. We will explain their functioning in a follow-up post. Today, I wanted to show you some impressions of the sampling using so-called Niskin bottles. These bottles are assembled around…

Celebrating our lab rats

Today seems a good day to celebrate those team members that are stuck in the clean laboratory container most of the day and night. As soon as the water collecting bottles (our “GoFlo” bottles) surface from their sampling trip from the deep ocean, the carriers will bring them to the container, where Natasha, Thato, Ryan…

Seawater pumps

One of our newest purchases this year was two so called in-situ pumps (“McLane pumps”). These pumps are lowered into the water, in our cases down to 250m and 500m on a cable, and kept at those depths for 1-2 hours to filter large volumes of water. In an hour, we can get 80L of…

Everyone gets a piece of pancake ice

The sea ice scientists collected pancakes from the ocean with a basket. Those pancakes were brought on board and stored frozen. Then they were subsampled, some were cut and some were used to drill ca. 30cm long ice cores. Our piece of pancake and ice core had to be treated with special precaution not to…

Pancake research

In the end, we never reached the pack ice. Despite sailing all the way to 63 degrees South. So, the differnt science teams on board decided that pancakes are just as fascinating and hectic pancake research began. First, the wave team (those studying wave occurrence, height and frequency, e.g. to find rogue waves or to…
