Description
Summary:Current warming, shifting hydrological regimes and accelerated permafrost thaw in the catchment of the Arctic rivers will affect their water biogeochemistry.The Lena River is the second largest Arctic river and 71 % of its catchment is characterized by continuous permafrost.Monitoring of Arctic rivers will enable to observe expected changes in matter transport such as an increase of dissolved organic matter (DOM) re-mobilization from permafrost.A number of biogeochemical variables are presented here in a unique high frequency throughout the whole year.The sampling of Lena River water is done near the Research Station Samoylov Island in the central Lena River Delta.The Samoylov research station allows a unique chance for continuous sampling since it operates throughout the year.
