Summary: This working group addresses issues related to lake gross primary production (GPP) and ecosystem respiration (R). Sensor network data and zero to 3D models are brought to bear on questions, such as: What assumptions are implicit when oxygen data from a specific depth is used to estimate whole lake metabolism? How do assumptions in metabolism modelling approaches affect metabolism estimates? How can we use high resolution models to upscale single point estimates of lake metabolism to whole ecosystems?
