Current Highlight

1973: Only DOE Marine Research Lab Begins Operation

On May 11, 1973, the Marine Research Laboratory, located at the mouth of Sequim Bay, in Washington, was officially dedicated with 80 invited guests in attendance. Known today as PNNL-Sequim, the facility was established to expand environmental research capabilities. In addition to on-site studies, early researchers aimed to conduct field investigations using mobile aquatic laboratories. Today, the campus is home to the only marine research facilities within the Department of Energy complex. Strategically situated, the campus plays a key role in marine-based research focused on helping the nation achieve sustainable energy, a sustaining environment, and coastal security.
