| Sumario: | Lake Alchichica is a deep, warm-monomictic lake in Puebla State, central Mexico. Water temperature, dissolved oxygenand chlorophyll a annual concentration patterns are compared under ENSO and non-ENSO conditions. The effects of ENSO ontropical Lake Alchichica lead to extreme values above or below the long-term averages in the physics, chemistry and biology ofthe lake. We find a narrower and slightly colder hypolimnion, larger thermal changes along the thermocline, a shallower thermocline,warmer epilimnion, later start of the hypoxic/anoxic condition of the hypolimnion, thinner hypolimnetic anoxic layer,and modest spring cyanobacteria bloom. |
