Researchers have developed a new technique to visualize the activity and distribution of enzymes that mobilize phosphate around plant roots.

Soil respiration—the flow of CO2 from the soil surface to the atmosphere—is one of the largest carbon fluxes in the terrestrial biosphere.

New analysis indicates that emissions from abandoned mines will contribute to higher emissions than previously thought.

Early achievement of net-zero greenhouse gas emissions in California brings much larger health benefits than economic cost.

Scientists at the U.S. Department of Energy’s Pacific Northwest National Laboratory have developed and continue to maintain a global database of measurements made of soil-to-atmosphere CO2 flows, termed soil respiration.

Existing techniques to detect pertechnetate in the environment have drawbacks. PNNL’s redox sensor technology uses a gold probe to accurately and efficiently measure low levels of pertechnetate—and possibly other contaminants—in groundwater

A new procedure for estimating sunlight reflection provides insight into feedbacks that affect Arctic warming.

A recent paper published in Water Resources Research found that the spatial variability of subsurface sediments, and seasonal fluctuations in a river’s water level, influences the behavior of a uranium contaminant plume, particularly in ...

Tower, aircraft, and satellite observations combined to evaluate weather forecast model.

Researchers adding water to the surface of alumina measured some surprising results that raise important questions regarding the fundamental reactions that govern chemical transformations of aluminum oxides and hydroxides.

Scientists at the Interfacial Dynamics in Radioactive Environments and Materials (IDREAM) sort out which compounds are present and their concentrations, providing an important new tool with broad applicability.

DOE researchers investigated the role of microbial genetic diversity in two major subsurface biogeochemical processes: nitrification and denitrification.

Nighttime interaction between Bay Area pollution and biogenic isoprene led to efficient formation of secondary organic aerosols.

Tree presence impacts how soils respond to temperature change in coastal forest.

An integrated water model quantifies the impact of water management on thermoelectric power plant generation.
