Integrating hydrogeology and biogeochemistry are required to model the dynamics of geochemical processes occurring in river corridor zones where groundwater and surface water mix.

Theoretical analysis reveals flow variations that happen over longer time periods affect a plume’s spread and center of mass.

Knowing which bacteria in a community are involved with carbon cycling could help scientists predict how microbial carbon storage and release could influence future climate dynamics.

Extreme sea levels will become 100 times more frequent by the end of the century around the world, according to a new study.

A new study shows that, when starved, some trees turn to self-digestion before dialing down energy storage.

Maggie McKeon honored by fellow costal and estuarine professionals as lead author of an outstanding publication in coastal oceanography.

A new research partnership between PNNL and the University of Nevada, Reno aims to tackle critical challenges such as climate change, infrastructure resilience and cybersecurity.

The Washington State Academy of Sciences consists of more than 300 elected members who are nationally recognized for their scientific and technical expertise.

PNNL provided ultra-low measurements of argon-39 to date groundwater as part of a collaborative study of the aquifer in California’s San Joaquin Valley. PNNL is one of only a few laboratories worldwide with this capability.

Research shows that previous drought and flooding conditions strongly influence soil respiration and carbon composition.

The multi-year project funded by DOE’s High Energy Physics program will focus on using machine learning to prevent power outages.

Principles derived from coastal wetlands to describe wetland channel cross-sections were applicable to the Columbia River estuary, but not the tidal river.

Understanding the fundamental relationships between river flow, water exchange, and nutrient cycling can inform ecosystem effects of river regulation.

Scientists at PNNL and the Confederated Tribes of the Colville Reservation identify acres of spawning habitat in the Upper Columbia River.

This is a story of how Nikki Sather's career journey studying the pulse of the Pacific Northwest's ecosystems began with a salmon's heartbeat. Sather currently works as an earth scientist at PNNL's Marine and Coastal Research Laboratory.

Understanding the Earth as a complex, dynamic system includes investigating what happens on, above and below its surface.

An updated version of a widely used database will provide powerful insights into the global carbon cycle.

Niri Govind and Amity Andersen co-hosted a workshop to explain how to use theory and modeling in the interpretation of X-ray absorption spectroscopy data.

Variability in field measurement conditions likely does not impact estimates of an important flux in the global carbon cycle.

PNNL physicist Jan Strube is defining experimental requirements to track high-energy particles at the proposed International Linear Collider.
