Subsite B: Erssjön

The lake stations are important parts of the Skogaryd catchment concept, which combines terrestrial, stream and lake ecosystems at a landscape level.

Continental GHG balance estimates are biased and inconsistent due to the lack of integrated landscape GHG assessments, and particularly the lack of coordinated flux measurements from lakes and running waters. Erssjön represents a typical lake in the (hemi-)boreal forest landscape. At this lake we monitor greenhouse gas emissions (CO2 and CH4), water chemistry and carbon sedimentation, addressing the recognition of the importance of inland water fluxes terrestrial greenhouse gas balances.

Measurements

Net emissions of GHG (CO2, CH4, H2O), water matter transport and internal function of the lake. For example are GHG flux studies with Eddie Covariance from a raft, manual chambers/water samples in transects out from the shoreline, water flow and matter measurements of streams (in and out of the lake), see SITES-Water for measuring program. Erssjön hosts the mesocosm infrastructure, SITES-AquaNet.
