Nutrient Cycling Through Wetlands in Southeast Alaska Affects Stream Carbon
A regional watershed evaluation in southeast Alaska revealed that wetlands affect stream carbon concentrations. The research team's findings were integrated to create a model for the production and export of abundant organic material from wetland soils that is closely associated with the flux of water in the coastal temperate rainforest. Nutrient cycling and export of carbon, nitrogen, and phosphorus in peatlands, and the cumulative impact of these cycles across several spatial scales is now better understood because of this collaborative terrestrial and aquatic research program. These combined studies established a fundamental understanding of the movement of carbon from terrestrial to aquatic zones in watersheds with significant wetland acreage. The information established values for dissolved carbon, nitrogen, and phosphorus export from watersheds that can be used to develop methods for evaluating watershed conditions by forest managers.
