Streams and flow stations
Small streams, lakes, and rivers make up a minuscule fraction of the landscape, yet they are of vital importance as they are the primary carrier of nutrients, pollutants, and other elements from terrestrial ecosystems downstreams to other lakes and eventually the ocean.
Knowledge of the spatial and temporal variability in aquatic ecosystems is fundamental for the understanding of biogeochemical cycles, as well as the causes and consequences of biodiversity, trophic complexity, and ecosystem stability.
Measurements
Within the SCR we have a sampling program for the streams that is linked to the SITES-water program (since 2013) where the water flow (continuously), water chemistry (bi-weekly; DOC/N, NH4+, NO3-, PO43-, Al, B, Ca, CU, K, Mg, Na, P, S, Si, Zn, Mn, Fe, F, Cl, NO2-, NO3-, UV-abs., pH, Conductivity), DNA (by-weekly) and DIC as well as methane. In addition to this program, MeHg and total Hg have been measure from the late autumn 2018 at several location in the stream system.
