Production–Irradiance (P–E) relationships based on hourly averaged of AEC‐based benthic metabolism and PAR (in μmol quanta m⁻² s⁻¹). (A) Seasonal P–E relationships at the CW. Note that during the winter oxygen uptake rates were mostly correlated with temperature and thus higher during daytime. Averaged R ² ranged from 0.69 during the spring to 0.93 during the autumn. (B) Integrated annual P–E relationships for each reach based on the available benthic oxygen fluxes.
