Tim Johnson has been selected for an open-ended term as associate editor of the Groundwater journal.

Book on hydrogeological electrical imaging offers groundbreaking insights to help students and practitioners pioneer the subsurface frontier.

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

A team led by researchers at PNNL demonstrated a new way to monitor deep subsurface fractures.

A new microbial community model reveals previous exposure to hydrologic variation influences a species’ specialized biogeochemical functions.

Detailed characterization of molecules in, under, and along the Columbia River reveal potential mechanisms for biogeochemical cycling.

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.

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

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 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.

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