Effects of Water Flow Variation in Large Rivers Exacerbated by Drought
Biogeochemical activity in the hyporheic zone (HZ), sediments where the flowing waters of a river mix with shallow groundwater, supports many of the biological processes that occur within a watershed.
Gaps Identified to Improve Accuracy of CO2 Fluxes Measured By Eddy Covariance Systems
Turbulent vertical fluxes of heat, water vapor, and carbon dioxide (CO2) occur constantly between land surfaces and the atmosphere.
Key to Understanding How Watersheds Function Lies in the Sediment
Co-authors of a paper in Hydrological Processes led by PNNL researchers Zhangshuan Hou, Timothy Scheibe, and Christopher Murray, produced a map that identifies different classes of sediments which compose the riverbed along the Hanford ...
Nutrient-Hungry Peatland Microbes Reduce Carbon Loss Under Warmer Conditions
Enzyme production in peatlands reduces carbon lost to respiration under future high temperatures.
Fire Increases Ecosystem Vulnerability to Future Disturbance Events
A new study examines how back how back-to-back extreme events can affect a forest landscape.
