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.

Turbulent vertical fluxes of heat, water vapor, and carbon dioxide (CO2) occur constantly between land surfaces and the atmosphere.

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 ...

A multi-institutional team of scientists developed a new sensitivity analysis framework using Bayesian Networks to quantify which parameters and processes in complex multi-physics models are least understood.

Reactive transport models (RTMs) are used to describe and predict the distribution of chemicals in time and space, in both marine and terrestrial (surface and near-surface) environments where microbially-mediated processes govern...

Hydrologic exchange flows (HEFs) increase the contact between river water and subsurface sediments thereby playing a critical role in biogeochemical and ecological functions along river corridors.

Hydrologic exchange fluxes (HEFs) between rivers and surrounding subsurface environments strongly influence water temperatures and biogeochemical processes. Yet, quantitative measures of their effects on the strength and direction of such e

CME investigators Daniel Martin (Yale) and Samantha Johnson (PNNL) received a team science award at the 2019 Energy Frontier Research Centers (EFRC) Principal Investigators' Meeting in Washington, D.C. in July 2019.

Prof. Yogesh (Yogi) Surendranath of the Center for Molecular Electrocatalysis (CME) was honored with a Presidential Early Career Award for Scientists and Engineers.

Energy storage is slowly shifting utility planning practices from the current paradigm, which ensures grid reliability by building reserve generation resources, to ensuring grid reliability by optimizing grid services.

Trouble on the electric grid might start with something relatively small: a downed power line, or a lightning strike at a substation. What happens next?

A PNNL technology enables automated Economic Dispatch, which coordinates the use of energy in a manner that enhances distributed generation, efficiency, renewables, and grid reliability.

Vapor detection technology developed at PNNL can quickly and accurately identify explosives, deadly chemicals, and illicit drugs.

Pacific Northwest National Laboratory is leading efforts to address next-generation computing’s critical role in protecting the nation from cybersecurity threats.

PNNL researchers are developing the only tool that can control large-scale distributed energy resources in real time.

The U.S. Department of Energy's (DOE’s) Pacific Northwest National Laboratory issued its annual report on distributed wind.

Bringing together federal elected officials, business leaders, educators, and PNNL representatives, the Association of Washington Business (AWB) held its 2019 Federal Affairs Summit in Richland on August 19 and 20.

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

PNNL helped teach the next generation of principal investigators about aerosols—tiny atmospheric particles that can affect the Earth’s climate—during the 2019 Aerosol Summer School.

Kristin Burnum-Johnson, Richard Saldanha, and James Stegen of the Department of Energy's Pacific Northwest National Laboratory have each been selected to receive 2019 Early Career Research Program awards from the U.S. Department of Energy.
