Textul licitației
Most measurements are taken in connection with hydropower plant development and mainly in regulated rivers. The measurements are mainly long-term measurements, starting around 1980 with loggers. The stations are equipped with temperature loggers attached in a heavy metal box in the streaming river. The metal box is fixed to the riverside with a chain. The data is internally stored in the logger. Since the loggers have a limited lifetime, they need to be replaced to maintain our capacity. NVE also operated some stations measuring water temperature in lakes down to 100 m. The stations are equipped with an anchored buoy with a vertical wire below. The temperature loggers are attached at approximately ten fixed depths. Since ice frequently move buoy to shallow water, we need pressure measurements to see the actual logger depth. The loggers have a limited lifetime, so they need to be replaced
