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 expose the ice core to metal or microbial contamination. The one dragged along the deck was obviously not for trace metal or genomic analysis, but it gives you an idea of the size and weight of the ice blocks. Sometimes the eager basket underestaimted the pancakes (the basket is ca. 2 x 2m to give you an idea of the size of the ice floe). The different teams on board will use their blocks and cores for various purposes; the sea ice engineers to study the structural properties as well as breaking patterns, others including our team to study the macro- and trace metal nutrient content, the productivity in the ice and the sea ice community composition.
