Research project The project investigate climate impacts on carbon fluxes of whole networks of streams, lakes and rivers. Using field data and modelling we test hypothesis that greenhouse gas emission, carbon burial in sediments and carbon export downstream vary depending on the climatic conditions and the structure of the water network.
The project is financed by the Swedish Research Counsil.
The purpose is to study climate impacts on carbon fluxes of whole networks of inland waters - stream, rivers, and lakes). We focus on northern high latitudes, a region of critical importance in a changing climate because of its high density of inland waters and ongoing and predicted strong climate change.
Specific aims and methods include to:
(A) Collect empirical data from different types of inland water networks across gradients in temperature and precipitation to test hypothesis that the extent to which inland waters emit (carbon dioxide, methane), bury, and export carbon downstream depends on the different climatic conditions and the structure of the inland water network.
(B) Develop a model that to project future carbon fluxes from various types of inland water networks in response to changes in temperature and precipitation.
