Years of Mesocosm Experiments
02/2009 - 07/2009 and 11/2009 - 10/2010
Description of Facility

Outdoor, pelagic/benthic, freshwater

floating platform including 3 floating PE-rings with mesocosms reaching into the sediment, 47 m³ per mesocosm, each 2 m diameter and 15 m depth (see Fig. 1)

Controlled Parameters

1)   Water: e.g. nutrients, species composition (algae & zooplankton), carbon, metals, ecotoxicology

2) Sediment: e.g. nutrients, metals, ecotoxicology
Research Topics

Nutrients, quantification of sediment P-release,
effects of lanthanum modified clay on the P-release

Facility location(s)
Primary interests
Specialist areas

Mobile mesocosm structure, can be installed on other study sites
