Global monitoring system has been collecting measurements from 36 lakes in the world, including 10 European lakes. The lake in Olsztyn will be the first in Poland to feed data on water quality and climate change factors to the system.
The project author Prof. Julita Dunalska told PAP that the measuring buoy designed and built in Olsztyn undergoes last tests on Lake Kortowskie. Starting next spring, it will be permanently anchored in the deepest place of the lake.
The device will measure a number of parameters of the water, including temperature, pH, turbidity, the oxygen, chlorophyll and phycocyanin content, which will allow to monitor the occurrence of cyanobacterial blooms. Meteorological equipment on the buoy will record air temperature, wind speed and solar radiation.
Measurements will be transferred automatically every two minutes to the monitoring centre in the Department of Environmental Protection Engineering at the Faculty of Environmental Sciences, University of Warmia and Mazury, and from there to the Global Lake Ecological Observatory Network (GLEON).
Previous studies of water required sampling of the lake each time by the employees of Olsztyn university. With the measuring buoy, scientists will have steady flow of a much larger amount of data and the ability to monitor the quality of water without leaving the lab. Increased frequency of measurements will ensure deeper understanding of processes occurring in the lake.
In the future, researchers at the University of Warmia and Mazury would like to include the Great Masurian Lakes in the global monitoring system.
