Lake Rotoiti fixed buoy data

Description: This dataset contains high-frequency environmental measurements collected by a fixed sensor buoy deployed in Lake Rotoiti. The buoy was equipped with a temperature string spanning the water column, along with surface sensors for chlorophyll-a, 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, and wind direction. These observations support the characterization of physical, chemical, and biological dynamics in Lake Rotoiti over time.
