Lake Rotoehu fixed buoy data

Description: This dataset contains high-frequency environmental measurements collected by a fixed sensor buoy deployed in Lake Rotoehu. The buoy was equipped with a temperature string spanning the water column, along with surface sensors for pH, chlorophyll-a, phycocyanin, and dissolved oxygen. Additional dissolved oxygen measurements were recorded at the lake bottom. A meteorological station mounted on the buoy recorded atmospheric conditions including wind speed, air temperature, relative humidity, and solar radiation. These observations support the characterization of physical, chemical, and biological dynamics in Lake Rotoehu over time.
