KUOW interviewed PSI’s Aimee Kinney today about the impacts of shoreline armoring on the Puget Sound ecosystem. Kinney was the lead author of an analysis report of recent nearshore studies funded by the Washington Department of Fish and Wildlife. New studies reveal that shoreline armoring degrades beach ecology and hurts Puget Sound species like forage fish and salmon. Read the analysis report on the Encyclopedia of Puget Sound.
For more than a hundred years, property owners have seen shoreline erosion as the enemy. They have battled it with startling amounts of concrete and have lashed together so many protective beach structures that about a third of Puget Sound’s shoreline is now classified as armored. It’s a fitting term for this longstanding battle against the elements. But it turns out that in many cases erosion is actually a good thing—crucial, according to scientists— because it provides the sand and gravel needed for healthy beaches. Now environmental agencies are encouraging the removal of bulkheads or their replacement with more natural erosion controls, such as logs embedded in the beach. New maps identify locations where bulkhead removal is likely to provide the greatest ecological benefits.
Our series on shoreline armoring continues today with two new stories. Studies show that a significant number of shoreline structures are being built illegally without required permits. We also report on efforts to educate shoreline property owners about alternatives to environmentally-damaging concrete bulkheads.
Our online magazine Salish Sea Currents launches a six-story series today focusing on shoreline armoring in the Puget Sound region. Close to a third of Puget Sound’s shoreline is classified as armored with bulkheads and other structures meant to hold back storm surge and erosion. But new studies reveal the often significant toll this is taking on the environment. The series kicks off with a look at armoring’s impact on beach ecology and forage fish habitat.
Local agencies and stakeholders—including PSI— were in D.C. today to advocate for Puget Sound. Follow some of the action on social media, including Twitter posts at #saveoursound and #saveamericassound. Among the day’s highlights was a new stormwater bill introduced by Representative Derek Kilmer, who announced the legislation on Facebook.

KUOW’s Bill Radke speaks with PSI director Joel Baker about a recent NOAA study identifying dozens of pharmaceuticals—from Prozac to Valium to bug spray—that are showing up in Puget Sound salmon.
UW Today reports on a recent paper co-authored by PSI lead ecosystem ecologist Tessa Francis. The paper, published in the journal Ocealogia, describes how individual herring populations in Puget Sound exhibit a portfolio effect, collectively influencing and stabilizing the region’s population as a whole. Francis teamed up with the paper’s lead author UW doctoral student Margaret Siple to analyze more than 40 years of herring data on 21 subpopulations in Puget Sound.
Concerns are growing that an earthquake or major ship accident could cause a failure that would halt ship traffic — or, worse, drop water levels in Lake Washington and Lake Union by up to 20 feet. That could mean stranded boats, disabled bridges and big problems for salmon restoration.
The News Tribune reported on an upcoming discussion series on a proposed methanol plant in Tacoma. The series is sponsored in part by our parent group the Center for Urban Waters at the University of Washington.
- A four-part series on Tacoma’s proposed methanol plant starts Thursday at UWT
- Joel Baker, the science director at the Center for Urban Waters, hopes to focus on the facts
- Whether Tacomans will be receptive remains to be seen
There is a nice story in The News Tribune today on the upcoming Radiolab event in Tacoma. The January 22nd show at the Pantages Theater will focus on Northwest water issues and features a panel of environmental leaders, including PSI Director Joel Baker. The paper calls Joel and his lab “the ‘CSI’ of water science” and highlights some of their research into the high prevalence of household chemicals in local waterways.
“What we find in the water is by and large what you find in your house, from refrigerators to medicine cabinets,” Baker told the paper. The article describes how Baker and his group at the Center for Urban Waters are finding everything from artificial sweeteners to long-banned substances like DDT in nearby Puget Sound. Known as emerging contaminants, these substances often escape filtration systems and can be found in levels that, although tiny—sometimes in the parts per billion or even trillion—can still be potentially harmful.
From orcas to starfish to humans, disease affects every living creature in the ecosystem. Scientists are increasingly alarmed by its potential to devastate already compromised populations of species in Puget Sound.
Our Director Joel Baker is part of a panel of four environmental leaders in Puget Sound who will be interviewed onstage at the Inside Radiolab show next week in Tacoma. Radiolab’s Robert Krulwich will host the January 22nd event at the Pantages Theater where he will interview panelists about Northwest water issues.
In addition to Baker, other panelists include Jennifer Chang of the Puyallup Watershed Initiative, Ryan Mello, Executive Director of Pierce Conservation District and Sheida Sahandy, Executive Director of the Puget Sound Partnership.
Radiolab’s quirky take on science has made it one of the Internet’s most popular podcasts, with more than 4 million downloads. It is also broadcast on over 450 public radio stations around the country. The live theater presentation will go behind the scenes of the show, with Krulwich talking about how he and his co-host Jad Abumrad create some of radio’s most compelling science journalism. The show begins at 7:30.
