In general, Arctic lake systems are classified as oligotrophic due to their low primary production, represented in chlorophyll values of 0.8-2.1 mg/m3. The lake’s water column, or limnetic zone, is well-mixed; this means that there are no stratifications (layers with different temperatures). During winter (October to March), the surface of the lake is ice covered. During summer (April to September), ice melts and the water flow and evaporation increase. Consequently, the two climatic periods (winter and summer) in the Arctic region cause a typical hydrologic behavior. This hydrologic behavior influences the physiochemical subsystem of the lake.  Table 1 show summary statistics of the daily variables we obtained from the Arctic lake simulation. The model used is deterministic, so there is no variation in different simulation runs. Table 1 depicts a higher dispersion for variables such as temperature ($T$) and light ($L$) at the three zones of the Arctic lake (surface=S, planktonic=P and benthic=B); Inflow and outflow ($I&O$), ($I$&$O$),  retention time ($RT$) and evaporation ($Ev$) also have a high dispersion, $Ev$ being the variable with the highest dispersion.
