AWI scientists Oliver Hauck and Björn Suckow took part in the North Sea Conference 2025 in Oldenburg - and won two awards. In the North Sea Video & Photo Contest, their contributions took first place in two categories: A photo by AWI photographer Esther Horvath won in the “North Sea Places” category. A video produced by Heide Matz and Carlotta Labitzke won in the “Free for All” category. The entries showcase the CLANCY project's efforts to contain the invasive mitten crab.
