Crampton Lake is the core aquatic site in NEON's Great Lakes Domain 05 located on property of the University of Notre Dame Environmental Research Station (UNDERC), which serves as NEONs core terrestrial site in the Great Lakes Domain. Most of Crampton Lake is in Vilas County, Wisconsin, but a small portion of the northern shore of the lake is across the border, in Gogebic County, Michigan. UNDERC is approximately 7500 acres of mixed and hardwood forests as well as open water and wetlands. Crampton Lake Crampton Lake is approximately 26 hectares surface area. The max depth is about 17.5 meters and average depth around 5 m. Structurally, there are two significant bays and one island. There are two deep holes which account for the max depth while much of the bottom is 1-10 m deep. 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. 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. Eight groundwater wells throughout the site collect specific conductivity, water tempertaure, and elevation of groundwater.
