Dorsch Data is an installation that visualises the decline and near extinction of the cod population in the western Baltic Sea, focusing on the effects of overfishing. Life in northern Germany is closely linked to the Baltic Sea. Fishing and seafood form an integral part of the local culture, yet the sea is becoming increasingly affected by climate change and human activity. This interactive visualisation enables visitors to explore the data physically and understand and compare the dramatic decline in the cod population. The project was exhibited at Einblick Ausblick 2024 in Kiel, Germany.
