COMPASS points to understanding nature’s transition zones—areas that can be dry land at times and under water at others.

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

Tools for advancing effective large-scale ecosystem restoration outcomes to maximize both ecological and economic benefits.

Culminating 10 years of study, researchers at PNNL’s Marine and Coastal Research Laboratory developed a new predictive framework for estuarine–tidal river research and management.

Changes in water volume tend to be smaller in managed watersheds but occur earlier.

PNNL is studying the movement of lamprey fish, which are culturally and historically important to the Pacific Northwest, on rivers and through hydroelectric dams.

Oil spills could be cleaned up in the icy, rough waters of the Arctic with a chemically modified sawdust material that absorbs up to five times its weight in oil and stays afloat for at least four months.
