River gauging station data from two streams in the Greiner Lake watershed, Cambridge Bay, Victoria Island

Climate change is expected to be more severe in the Arctic compared to other regions, where changes in both temperature and precipitation are predicted in the near future. These changes will have a significant impact on the ecosystems of this region. Of special concern is the disruption of the carbon cycle in the Arctic, where positive feedbacks may further accelerate changes in the global climate. Tundra ecosystems store almost half of the global soil carbon, and the warming of the Arctic, the increase in precipitation and subsequent enhanced permafrost melting could release this sequestered carbon, and thus hasten global climate change. Therefore, the understanding of interactions among hydrology, sediment and element cycles, climate, and ecosystems is of crucial importance in predicting the effects of climate warming on arctic terrestrial ecosystems. Thus, two river gauging stations have been installed in the Intensively Monitored Area (IMA) of the CHARS Experimental and Reference Area: station #1 on the river connecting First Lake and Greiner Lake (69.203492°, -104.805418°), while station #2 on a small thermokarst stream connecting two shallow lakes in the northern part of the IMA (69.246597°, -104.831333°). Both river gauging stations recorded data every half hour from the date of their installation on August 3rd, until September 16th, the day the sensors were retrieved from field and the stations prepared for winter. The river gauging stations recorded: water turbidity (NTU), water level (m), as well as water temperature (degrees Celsius).
