Little Rock Lake (LIRO) is a relocatable site and part of NEON's Great Lakes 05 Domain. LIRO a seepage lake located in Wisconsin. LIRO is representation. No streams enter or drain the waterway. More than 98 percent of the lake's water comes from rainfall and snowmelt, so Little Rock is highly sensitive to atmospheric pollutants. This site has one meteorological station located in the riparian area and one meteorological station above water on a buoy. The met stations are outfitted with the a subset of the same sensors used at terrestrial sites. Measurements include wind speed and direction, air temperature, barometric pressure, relative humidity, shortwave radiation, and PAR. Remote sensing surveys of this site collect lidar, spectrometer and high resolution RGB camera data. Seven groundwater wells throughout the site collect specific conductivity, water tempertaure, and elevation of groundwater. This site has one buoy-mounted sensor station and an inlet station and outlet station. At the buoy, the automated instrument measurements are: PAR at water surface, PAR below water surface, temperature at a specific depth in surface water, water quality (specific conductivity, chlorophyll a, dissolved oxygen content, pH turbidity, and fDOM), and nitrate. At the inlet and outlet stations, the measurements are: PAR below water surface, elevation of surface water, and temperature in surface water. Field ecologists collect the following types of observational data at this site: aquatic organisms (Aquatic Microbes (surface water),macroinvertebrates microalgae, plants and macroalgae, zooplankton. Biogeochemical data on plants,sediment water and particulates.As well as physical aquatic data on bathymetric maps, stage,secchi depth and depth profiles, and riparian assessment.Total data products planned for this site: 77
