I was invited to take part in a research expedition in the Baltic Sea arranged by Örebro University and Pangaea Exploration, which I gratefully said yes to. The expedition has been running since the beginning of August, but I joined them on Saturday. So now I find myself miles from the nearest coast, on board the “Sea Dragon”, a Global Challenge Vessel, and part of a small but enthusiastic crew. The goal of this expedition is to study marine litter, a growing problem for the world’s oceans.
