  text: Climate forecasts project a global increase in extreme weather events, but
    information on the consequences for ecosystems is scarce. Of particular significance
    for lakes are severe storms that can influence biogeochemical processes and biological
    communities by disrupting the vertical thermal structure during periods of stratification.
    An exceptional storm passing over northern Germany in July 2011 provided an opportunity
    to assess the consequences and underlying mechanisms of such extreme events on
    the interplay between the physics and ecological characteristics of a deep, nutrient-poor
    lake. Wind speeds were among the most extreme on record. A suite of variables
    measured throughout the event consistently indicates that a cascade of processes
    pushed the clear-water lake into an exceptionally turbid state. Specifically,
    thermocline deepening by the storm-entrained cyanobacteria of a deep chlorophyll
    maximum located at about 8 m depth into the surface mixed layer. Released from
    light limitation, intense photosynthesis of the cyanobacteria boosted primary
    production, increased algal biomass, raised the pH and thus induced massive calcite
    precipitation to a level never observed within three decades of lake monitoring.
    As a consequence, water transparency dropped from 6.5 to 2.1 m, the minimum on
    record for 40 years, and the euphotic zone shrank by about 8 m for several weeks.
    These results show that cyanobacterial blooms not only are promoted by climate
    warming, but can also be triggered by extreme storms. Clear-water lakes developing
    a deep chlorophyll maximum appear to be particularly at risk in the future, if
    such events become more intense or frequent.
