Turbulence production in the upper mixed layer, thermocline and bottom waters of lakes is intensified when frontal systems which induce cooling and higher winds pass through a region. The amplitude of internal waves, whose breaking causes turbulence, increases during these events and varies with bottom slope. In addition, these frontal systems induce stream inflows which spread into lakes at various depths as a function of temperature and discharge. Consequently, during storm events, we can now envision hot spots where solute fluxes and metabolic activity are intensified and cold spots where change is only possible if currents transport water from hot spots. The proposed work will build upon this knowledge to design experiments to locate these hot and cold spots and quantify the bacterial and primary productivity. Via time series arrays, collaborative modeling efforts, and adaptive sampling based on real time data on the physical state of the lakes, we will be positioned to more accurately quantify lacustrine bacterial and primary productivity than ever before. Studies will be conducted in Mono Lake and research preparations and analysis of water samples will be conducted at SNARL.
