Influences of organic carbon speciation on hyporheic corridor biogeochemistry and microbial ecology
How to Spy on a Fish: Tracking Salmon Migration in the Columbia River Basin
Salmon are a critically important species in the Pacific Northwest – not only ecologically but also economically and culturally...
High Throughput Center
At PNNL’s High Throughput Center, robots handle routine and repetitive small-scale laboratory tasks to improve the researchers’ labor landscape—and productivity.
Charting the Frontier of Electron Microscopy
A gathering of international experts in Portland, Oregon, explored the future of electron microscopy and surfaced potential solutions in areas including new instrument designs, high-speed detectors, and data analytics capabilities.

Diversity and Function Within Soil Microbial Communities
The microbial communities within the loose, friable aggregations of organic and mineral components in soil are highly organized spatially, shaped in part by the structure of the soil itself.
A New Role for Microbes in Peatland Nitrogen Supply
Nitrogen is a critical nutrient regulating productivity in many ecosystems and influences nutrient availability by affecting organic matter decomposition rates.
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 ...
