Headwater C fluxes This research focuses on understanding processes controlling temporal and spatial variability in aquatic carbon fluxes in headwater streams. Headwater streams are areas of active carbon cycling because of steep topographic gradients, complex soil and vegetation patterns, and an abundance of small lakes and streams. The project will combine information from the following major components: High-frequency measurements of aquatic carbon fluxes using in-stream sensors will provide information on temporal dynamics at unprecedented resolution. A geostatistical model will be developed to characterize relations between landscape type (e.g., wetlands, forest, tundra) and aquatic C dynamics and fluxes. Variations in fluxes...

Wetlands that are hydrologically connected to stream and river networks are commonly considered to be major sources of carbon that may be biologically or photochemically processed in-stream, or exported to coastal regions. However, very little is known about the potential or actual lateral carbon fluxes from different major wetland types, or the downstream fate of that carbon (rapid decomposition vs. sequestration vs. export). Major questions: What is the variability in potential carbon sources (as dissolved organic C, dissolved inorganic C, CO2 and CH4) from major inland wetland types to inland waters? What metrics and/or markers (chemical,...
