The lakes in SITES AquaNet and SITES Water
Seven lakes at seven different stations are central for SITES AquaNet and SITES Water. The monitoring for SITES Water, including lake and stream sampling, is carried out in six of the stations catchments and therefore covers a gradient in aquatic biogeochemistry e.g. nutrient concentrations, water color and catchment characteristics. SITES AquNet offers experimental manipulations in lakes with varying environmental conditions along a latitudinal gradient.
