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

Agent-based models of water resource management can include the interaction between human-engineered systems and natural processes

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.

With the help of a diagnostic tool called the Salish Sea Model, researchers found that toxic contaminant hotspots in the Puget Sound are tied to localized lack of water circulation and cumulative effects from multiple sources.

PNNL coastal ecologist Heida Diefenderfer was a featured speaker in February at the National Academies of Sciences, Engineering, and Medicine’s Government-University-Industry Research Roundtable on policy and global affairs.

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

PNNL's Sensor Fish were deployed at Ice Harbor Dam to collect data from a new turbine. The data indicates the design changes are making travel through the dam less arduous for fish.

PNNL Emeritus Scientist Ronald Thom received the 2019 Environmental Leadership Award at the Northwest Straits Marine Conservation Initiative Conference.

The world’s largest scientific society honored Sue B. Clark, a PNNL and WSU chemist, for contributions toward resolving our legacy of radioactive waste, advancing nuclear safeguards, and developing landmark nuclear research capabilities.

PNNL’s Nuclear Process Science Initiative (NPSI) has developed a book that examines processes used to separate nuclear materials.

Study shows warmer surface and more rain reduce Arctic snow cover; keep temperatures climbing.

PNNL adds its expertise to an international expedition investigating the vulnerable central Arctic Ocean.

We are all citizens of watersheds, the terrestrial landscapes that determine how much water we have, how clean it is, where it goes, and how fast.

Researchers from Pacific Northwest National Laboratory reviewed the current state of knowledge about the impacts of climate change on soil microorganisms in different climate-sensitive soil ecosystems.

Enzyme production in peatlands reduces carbon lost to respiration under future high temperatures.

Nitrogen is a critical nutrient regulating productivity in many ecosystems and influences nutrient availability by affecting organic matter decomposition rates.

Despite a breadth of research on carbon accrual and persistence in soils, scientist lack a strong, general understanding of the mechanisms through which soil organic carbon (SOC) is destabilized in soils. In a new review article, researcher

The inner Salish Sea’s future response to climate change, while significant, is predicted to be less severe than that of the open ocean based on parameters like algal blooms, ocean acidification, and annual occurrences of hypoxia.
