Artificial stream and pond system

Hall and grounds with artificial guttering

The artificial stream and pond system (“Fließ- und Stillgewässer-Simulationsanlage” – FSA) of the German Federal Environment Agency’s field station in Berlin-Marienfelde is one of the largest and most modern mesocosm systems in the world. read more


Effect study "Irgarol"

Pigment analyses of aufwuchs (biological surface film) in stagnant water mesocosms under the effect of the anti-fouling agent Irgarol®Irgarol® is in the group of s-triazines and a biocidal agent which is used as an anti-fouling coating for marine vessels to prevent the attachment of algae and organisms on their hulls. Irgarol inhibits photosynthesis and is highly toxic for higher plants, algae and... read more

Filling the outdoor channel with sediment

In order to test, for example, the effect of certain substances on aquatic communities, the mesocosms has to be adequately designed and has to be rich in structure providing a wide variety of habitats for different species. In order to meet these requirements, sand and mud (soft sediment) and selected aquatic plants and organisms are introduced into the stream and pond mesocosms. read more



Retention of substances (sediments, nutrients, pollutants) in river flood meadowsIn 2002 and 2003, a working group of the Institute for Geographical Sciences at the Free University (FU) Berlin carried out a study on matter retention in river flood meadows. The background for this study was the renaturation of rivers and river flood meadows, something, which has become very topical following the re... read more
