Temperature at specific depth in surface water (DP1.20264.001)

Temperature at specific depths on buoys is measured every minute and is reported as 1-minute instantaneous measurements and 30-minute mean values. A temperature chain with between 3 and 10 thermistors (depending on lake depth) is affixed from the buoy at the water surface. The shallowest thermistor is located at 5 cm below the water surface. Deeper thermistors have their depth published with the data and vary for each lake or river. Latency: Data collected in any given month are published during the second full week of the following month.
