A new book explores our complicated connection to the ecosystem we call home. We interview author David B. Williams about Homewaters: A Human and Natural History of Puget Sound, published this month by the University of Washington Press.
Researchers are looking at the forces of discrimination that worsen the environmental health risks for some communities.
Years of struggle have led to reduced pollution and a stronger sense of community in the Duwamish Valley. As cleanup efforts there continue, environmental justice has come front and center for the area's diverse populations.
Close to 30% of Puget Sound's shoreline is armored with seawalls and other structures meant to protect beaches against rising tides and erosion. But science increasingly shows that these structures are ineffective and cause significant harm to salmon and other creatures. State and federal agencies have been encouraging private property owners to remove armoring in a race to improve habitat, but why did so much of it start appearing in the first place?
The geoduck has earned an honored place as Puget Sound's largest and most distinctive native clam, but how much do we really know about it? Often seen as a culinary curiosity, the geoduck has only been commercially harvested on a large scale since the 1970s, and the clam's current popularity is based mostly on demand from Asian markets. Nevertheless, this deep-burrowing mollusk has always been a signature part of the Salish Sea ecosystem.
Scientists believe that herring have been a staple of Salish Sea food and culture since humans first arrived here at least 12,500 years ago. That importance has continued into modern times, even as herring numbers have declined in parts of the region.
Northwest Coast First Peoples made clam garden terraces to expand ideal clam habitat at tidal heights that provided optimal conditions for clam growth and survival, therefore enhancing food production and increasing food security.
The audio files below are excerpts from a May 2013 interview with Donald Malins, former Director of the Environmental Conservation Division of NOAA Fisheries. Research by Malins and his colleagues in the 1970s and mid-1980s revealed high levels of industrial toxics in sediment-dwelling fish in Puget Sound, leading to the creation of Superfund sites in the Duwamish Estuary and Commencement Bay. Read a full profile of Donald Malins. The interview was conducted by Richard Strickland and Randy Shuman in cooperation with the Encyclopedia of Puget Sound as part of the Puget Sound Voices series. Additional assistance was provided by Jake Strickland.
In the 1970s and 1980s, research from a division of NOAA's Montlake Lab suddenly changed the way scientists and the public viewed the health of Puget Sound. Their discovery of industrial toxics in the region's sediment-dwelling fish led to the creation of two Superfund sites, and new approaches to ecosystem management across the Sound. The man at the forefront of this research was Dr. Donald Malins, featured here as part of the Puget Sound Voices series.
A botanist believes Coast Salish tribes once favored small islands in the San Juan archipelago for growing camas, an important food staple. Her studies may also show the vulnerability of these relic gardens to climate change as sea levels rise.
One of the first working models of Puget Sound was a scaled-down concrete reproduction, with actual water running through channels, around islands and into bays, inlets, and harbors. Motors, pumps and timing gears are part of an elaborate mechanism that replicates tides and river flows in the still-functioning model.
Treaty rights are critical to the sovereignity of Puget Sound area Tribes and are deeply connected to natural resource management. Five landmark treaties in our region were signed during a three-year period from 1854 to 1856 and continue to drive policy to this day.
Puget Sound is often referred to as the second largest estuary in the United States behind only Chesapeake Bay, 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.
Modern automobile tires are a complex mixture of chemicals, all used together in different ways to give tires their structure and properties, including riding comfort, safety and long life. Chemicals from tire wear particles are now thought to be responsible for the deaths of large numbers of coho salmon returning to spawn in Puget Sound streams.

For close to 100 years, Seattle's Ballard Locks has been one of the region's busiest waterways, drawing major boat traffic along with millions of tourists. But as it prepares to celebrate its centennial, the aged structure is also drawing the concern of engineers. They worry that an earthquake could cause the locks to fail, draining massive amounts of water from Lake Washington and Lake Union. In some scenarios, the two lakes could drop by as much as 20 feet, stranding boats, disabling bridges and causing big problems for salmon restoration.
Puget Sound is the second largest estuary in the contiguous United States. Today, we understand that estuaries — where freshwater and saltwater merge — are among the most productive places for life to exist.
This study compared recent and historical data to determine the presence of any significant changes in nutrient and oxygen concentrations subsequent to METRO discharge, examined seasonal cycles in water properties, and examined the flux of nutrients within the study area.
This 1954 report present the results of a geochemical investigation, based on existing data, of the waters of Puget Sound. Rivers draining into the Puget Sound and upwelled water moving in at depth from Juan de Fuca Strait are the chief sources of the chemical constituents in Puget Sound.
A scientific assessment of current status and future trends in resource abundance and environmental quality in the Strait of Juan de Fuca, Strait of Georgia, and Puget Sound
The decaying seawall along Seattle’s waterfront is providing scientists with an opportunity to improve long-lost habitat for migrating salmon. It could also show the way for habitat enhancements to crumbling infrastructure worldwide. One University of Washington researcher describes the project.
The Puget Sound Model was designed and built by the University of Washington School of Oceanography in the early 1950s to simulate the tides and currents of Puget Sound. A series of videos produced by the Encyclopedia of Puget Sound describes its construction and operation.
The Puget Sound Model was designed and built in the early 1950s at the University of Washington School of Oceanography as a research and teaching tool for understanding Puget Sound circulation patterns.
The Encyclopedia of Puget Sound spoke with Seattle Times reporter Lynda Mapes about the exhibit Elwha: A River Reborn, which opened at the University of Washington Burke Museum on November 23rd. The exhibit is based on the book of the same title by Mapes and photographer Steve Ringman, and tells the story of the largest dam removal in U.S. history.
Vern Morgas remembers the early days of scuba diving in Puget Sound.
The Salish Sea extends across the U.S.-Canada border, and includes the combined waters of the Strait of Georgia, the Strait of Juan de Fuca, Puget Sound Basin and the San Juan Islands (see map).
The name Salish Sea was proposed by Bert Webber in 1989 to reflect the entire cross-border ecosystem. Both Washington State and British Columbia voted to officially recognize the name in late 2009. The name honors the Coast Salish people, who were the first to live in the region.
