Photosynthesis shines as remediation tool
DOE/Pacific Northwest National Laboratory
Marine construction, wood treatment, agricultural chemical production, chlorine production-- for decades we have been dumping waste into our harbors, many of which are now considered some of the most contaminated hazardous waste sites in the United States. Battelle researchers at PNNL's Marine Sciences Laboratory have developed a promising technique for remediating contaminated sediments in seawater and freshwater ecosystems.

Measuring aquatic vegetation goes high-tech
DOE/Pacific Northwest National Laboratory
Using people to manually characterize aquatic vegetation in the coastal environment may no longer be the best method of capturing features in a marine environment.

No more free ride for phytoplankton
DOE/Pacific Northwest National Laboratory
They may not be terrorists, but they can be sneaky--phytoplankton. These single-celled algae can sneak into nonindigenous harbors and coastal waters via ships' ballast water. Toxins from the phytoplankton can be taken up by shellfish and become harmful to humans who consume the shellfish.

MSL's approach to eelgrass is spreading
DOE/Pacific Northwest National Laboratory
More than 60 percent of the world's population lives near the coast. In addition to the growing development and economic importance of coastal areas, there is a major push for maintaining and restoring coastal ecosystems.

Short-term estrogen exposure cuts fish fertility
DOE/Pacific Northwest National Laboratory
A new study by Pacific Northwest National Laboratory and the University of Idaho shows that exposure to estrogen affects adult fish as they swim through rivers, lakes and streams to spawn. The study suggests that when adult male fish are exposed to short-term and low concentrations of synthetic estrogen, their fertility can drop by as much as 50 percent.

It's not raining cats anymore
DOE/Pacific Northwest National Laboratory
The mystery of why panthers were dropping dead from the trees in the Florida Everglades was solved fairly quickly. The mystery of how they were being poisoned with mercury took a little longer. Scientists from PNNL's Marine Sciences Laboratory were part of a team of researchers involved with the initial assessment of mercury contamination in the Florida Everglades project between 1993 and 2000.

Researchers help computing reach its full potential
DOE/Pacific Northwest National Laboratory
It didn't take long for computers to turn typewriters, manual cash registers and similar devices into artifacts. Today, with everything from laptops to massive supercomputing capabilities, people have access to tools that perform complex tasks in a matter of seconds, saving vast amounts of time and money.

Regional program touts cooperation for economic growth
DOE/Pacific Northwest National Laboratory
Pacific Northwest National Laboratory's Office of Northwest Regional Programs (ONRP) is emphasizing cooperation as a way to energize economic development efforts in Washington, Oregon and Idaho.

Culvert technology may help young salmon muscle their way upstream
DOE/Pacific Northwest National Laboratory
Tens of thousands of culverts lie beneath roads in the Pacific Northwest, successfully moving water under the roadbed to preserve pavement and prevent flooding. At the same time, many are blocking juvenile salmon from migrating upstream to the habitat they need to survive and grow.
