  text: Metalimnetic oxygen minima are observed in many lakes and reservoirs, but
    the mechanisms behind this phenomena are not well understood. Thus, we simulated
    the metalimnetic oxygen minimum (MOM) in the Rappbode Reservoir with a well-established
    two-dimensional water quality model (CE-QUAL-W2) to systematically quantify the
    chain of events leading to its formation. We used high-resolution measured data
    to calibrate the model, which accurately reproduced the physical (e.g. water level
    and water temperature), biogeochemical (e.g. nutrient and oxygen dynamics) and
    ecological (e.g. algal community dynamics) features of the reservoir, particularly
    the spatial and temporal extent of the MOM. The results indicated that around
    60% of the total oxygen consumption rate in the MOM layer originated from benthic
    processes whereas the remainder originated from pelagic processes. The occurrence
    of the cyanobacterium Planktothrix rubescens in the metalimnion delayed and slightly
    weakened the MOM through photosynthesis, although its decaying biomass ultimately
    induced the MOM. Our research also confirmed the decisive role of water temperature
    in the formation of the MOM since the water temperatures, and thus benthic and
    pelagic oxygen consumption rates, were higher in the metalimnion than in the hypolimnion.
    Our model is not only providing novel conclusions about the drivers of MOM development
    and their quantitative contributions, it is also a new tool for understanding
    and predicting ecological and biogeochemical water quality dynamics.
