By Christopher Dunagan, Puget Sound Institute Recent studies have shown that Chinook salmon that spawn in the spring are genetically distinct from varieties that spawn during fall months. Experts are confronting the resulting ecological, social and legal implications of that finding. Each year, as the dark days of winter surrendered to the rebirth of spring, …
There are more than 45,000 residential properties along Puget Sound’s shoreline. Of those, almost half have some form of environmentally damaging shoreline armoring, researchers say. That makes private landowners a primary focus of state and federal armor removal efforts, but many landowners say they either lack funds or are unwilling to pay for sometimes costly …
Scientists are reporting some potentially good news about the health of Puget Sound’s streams. Ten years of data from 126 stream sites within King County have shown a slight improvement in water quality, according to the county’s Water and Land Resource Division. The study examined the variety of insects and other invertebrates that were collected …
This is a guest blog from Partners in Puget Sound Recovery, an inter-agency group focused on strategies for stormwater mitigation, habitat protection and shellfish recovery in Puget Sound. Project Spotlight: Replicable Model for Depave and LID Retrofits Overview: This project will conduct three depave and retrofit activities providing direct stormwater benefit to three communities resulting in …
The reported deaths this week of three more southern resident orcas have brought renewed urgency to efforts to save the critically endangered population of whales. Many scientists and policymakers are focusing on the orcas’ access to their main source of food, the Chinook salmon. Members of the orca population are appearing dangerously thin and malnourished. …
If you were to ask a group of experts to make a list of culturally important foods in the Pacific Northwest, it would not be a surprise if salmon rose to the top. But researchers say Pacific herring may have at times rivaled salmon in importance in the Salish Sea. Scientists believe that herring have …
By Jeff Rice When people hear about Puget Sound’s Grand Uncertainties Matrix, they aren’t always sure what to make of it. It sounds vaguely existential. Like something out of a Wachowski brothers film. But it turns out that this particular matrix doesn’t star Keanu Reeves and you don’t have to wear sunglasses and a trench …
The Puget Sound Institute’s Andy James is the corresponding editor of a 2019 report on monitoring and research activities focused on toxic contaminants in the Salish Sea. The report from the Puget Sound Ecosystem Monitoring Program covers a range of case studies including the occurrence of microplastics and pharmaceuticals in shellfish, PCBs in river otters and new findings …
By Christopher Dunagan After five weeks at sea, a team of 21 scientists from five countries returned Monday with some surprising findings about the mysterious lives of salmon in the Pacific Ocean, according to Laurie Weitkamp, a salmon biologist with NOAA’s Northwest Fisheries Science Center in Newport, Ore. “It was quite an experience,” said Weitkamp, …
The Shoreline and Coastal Planners Group spring meeting will focus on shoreline armoring in Puget Sound and will feature a presentation by Puget Sound Institute research scientist Aimee Kinney. The meeting will be held on on April 23rd at the South Seattle College Georgetown campus and will include assessments of updates to the EPA-funded Puget …
The Environmental Protection Agency’s National Estuary Program has issued a call for proposals for research into climate change risks to Puget Sound shellfish, marine water quality and public health. A total of $150,000 is available to fund up to three projects. Applications are due by 11:59 PM on April 8th. The full call for proposals …
Prior to European settlement, dense assemblages of Olympia oysters covered as many as 20,000 acres, or 26.7% of Puget Sound’s intertidal zone. Today they occupy about 5% of their original range, prompting a slew of state and federally-funded restoration efforts. Sarah DeWeerdt reports on the comeback of Puget Sound’s only native oyster for our magazine …
