A state law going into effect this month will significantly increase funding for the cleanup of abandoned and derelict vessels in Puget Sound. The funding will add about $4.3 million annually to remove hazardous sunken wrecks and related pollutants.
New research suggests that recovery efforts are working for Puget Sound’s threatened yelloweye rockfish. Preliminary models show "considerable improvement" in population numbers.
Puget Sound's glaciers are melting rapidly due to climate change. The North Cascades mountains have lost about 56% of their glacial ice while estimates show that glaciers in the Olympics could be gone within the next 50 years. Scientists say salmon and other species could be hard hit as the region loses its “giant storage tank” of ice.
Can restoring the natural balance of the Nooksack River also reduce flood risks? Officials on both sides of the U.S.-Canada border are taking note as climate change raises the stakes.
The marine heat wave that struck the Pacific Ocean in late 2013 also caused large changes in temperature in the Salish Sea, but scientists are still puzzling over the impacts of those changes on Puget Sound's food web. The so-called "blob" of warmer than average water was thought to have increased the production of plankton, which potentially benefits creatures like herring and salmon that feed on the tiny organisms. A new paper in the journal Frontiers in Marine Science calls that interpretation into question, pointing to a computer model that links the cause to higher-than-normal river flows in the region.
Puget Sound is one of the largest estuaries in the United States, but its overall size may be less important than its complexity. The place is defined by the mixing of saltwater from the ocean and freshwater from creeks and rivers that create an almost alchemical transformation of habitat. In this article, we look at the geologic forces that formed Puget Sound and made it the dynamic system that we understand today.
Large plumes of methane bubbles have been discovered throughout the waters of Puget Sound prompting questions about the Puget Sound food web, studies of earthquake faults and climate-change research.
Over the past year, the Washington Department of Fish and Wildlife has reported an unusually high number of sixgill sharks found washed up along Puget Sound's shoreline. Four dead sharks in all were spotted, alarming scientists who believe that the large predators use Puget Sound as a pupping ground. Sixgills are rarely seen in Puget Sound but are one of its largest fishes, reaching lengths of up to 16 feet. Some speculate that warmer-than-usual waters could be a factor in the deaths, but the cause remains a mystery. We spoke with Fish and Wildlife biologist Lisa Hillier.
Fishing for rockfish was once promoted as a sustainable alternative to salmon harvests, but when rockfish numbers plummeted, fisheries managers realized they had a problem. Now a rockfish recovery plan seeks to reverse the damage as scientists learn more about protecting this once-popular game fish.
