Marker Wadden

Study site

The Marker Wadden is a newly constructed archipelago in lake Markermeer, which aims to improve the lake’s degrading food web by stimulating primary productivity. The archipelago consists of five islands that add a currently missing habitat type to the lake: shallow, sheltered waters with high nutrient availability and gradual land-water transitions. We constructed and maintain a network of sensors in the waters between these islands (16 locations) that monitors the influence of the Marker Wadden on water quality and movements of five (acoustically tracked) species of freshwater fish.
