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 of individual species [...]
