Last water stop

We had our last station to collect water from the abyssal ocean yesterday. Just before yet another storm hit us. That last station was at ca. 41 degrees South and marked the end of our transect as we could not reach our planned last station at 38 degrees South anymore, we had to make our…

Winter Time low productivity

At c. 52degS c. 28deg E in what most likely is the Polar Frontal Zone and about a day away from the Polar Front. The photo shows a filter used to collect phytoplankton material, for pigment analysis, having ran c.30L of surface ocean water through it. Compared to summer time (Dec-Jan 2017) in the same…

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…
