A new study shows a surprising decline in some toxic chemicals in Puget Sound fish, while levels of PCBs increased in some cases. Scientists say the study shows that banning toxic chemicals can work, but old contaminants remain a challenge as they continue to wash into Puget Sound.
These days, you may know the Encyclopedia of Puget Sound as a news source. Our magazine stories and blogs cover science as it happens across the Salish Sea, from research on salmon recovery to toxic chemicals in the food web.
There is no other publication focusing strictly on Puget Sound science, and — we’ll be bold here — we strive to provide the best such coverage in the region. Not because we have the most stories or the biggest staff (we don’t), but because we report the news that you need to know.
We work closely with the scientists on the ground and often hear what’s happening before the major media outlets. We work hard to get the stories right, and we provide context that other publications can’t.
That context is one of the most important parts of the Encyclopedia of Puget Sound. We are a news source, but we are also a resource — an encyclopedia. If you want to know how scientists and policymakers view the ecosystem and how they are working to protect it, we have organized it from A to Z.
This August, as the dog days settle over Puget Sound and forest fires rage in the distance, we’ll continue to build the encyclopedia behind the scenes. Do you want to know more about toxic algae blooms or zooplankton? How about floodplains or the impacts of shoreline armoring? There’s plenty to discover. You can use the encyclopedia in your classes. Share it with policymakers. Identify thousands of species. Find out the age of a rock fish. Scope out local beaches. The website continues to get better every day, and we are glad to bring it to you.
In recent decades, hundreds of millions of dollars have been spent to restore habitat for Puget Sound salmon. This month, PSI senior writer Christopher Dunagan looks at how scientists are gauging their progress. Are environmental conditions improving or getting worse? The answer may depend on where you look and who you ask.
Our 2016 article “Killer whale miscarriages linked to low food supply” provided an early look at a study published this week in the journal PLOS ONE.
PSI senior writer Christopher Dunagan wrote the article based on research that was presented at the 2016 Salish Sea Ecosystem Conference, and it remains a helpful summary of the newly published findings.
Scientists have found that Puget Sound’s endangered Southern Resident Killer Whales are experiencing a high rate of miscarriages in large part because they are not getting enough food. The whales depend primarily on diminished populations of Chinook salmon and this scarcity magnifies other existing threats ranging from toxic PCBs to noise pollution.
The PLOS ONE study was co-authored by Samuel K. Wasser , Jessica I. Lundin, Katherine Ayres, Elizabeth Seely, Deborah Giles, Kenneth Balcomb, Jennifer Hempelmann, Kim Parsons, and Rebecca Booth. Dunagan’s article summarizing their findings is available on the Encyclopedia of Puget Sound.
This week in Salish Sea Currents: PSI senior writer Christopher Dunagan reports on a new approach to flood control in Puget Sound. Rivers, scientists say, can be contained by setting them free. Conservationists hope this is good news for salmon recovery.
The story is part of our ongoing series on the science of Puget Sound recovery. Funding for the series is provided by the Environmental Protection Agency.
Can nature make you happy? Science weighs in: A recent study by PSI social scientist Kelly Biedenweg found that Puget Sound residents reported increasing happiness the more they engaged with the natural environment.
“We (in the Pacific Northwest) are pretty much the leaders in trying to understand how happiness and integration with the environment relate to each other,” Biedenweg told The News Tribune, which featured the study in its April 7th edition. Biedenweg has been working with the state of Washington to identify indicators of human well-being such as happiness, physical and psychological health and economic prosperity for the Puget Sound region.
The study was published in the Journal of Environmental Psychology and was funded by The National Science Foundation and the Environmental Protection Agency. It was based on online surveys of 4,418 area residents across eleven Puget Sound counties.
A version of The News Tribune story was also published on April 9th in The Olympian.
New in Salish Sea Currents: We continue our series on Puget Sound’s EPA-funded Implementation Strategies. This week we take on Chinook recovery.
As threatened Chinook populations continue to lose ground, the state is looking to new strategies to reverse the trend. In the Skagit watershed, the scientists — and the fish — are among those leading the way.
Puget Sound-area writer Bob Friel reports from the newly-established Fir Island Farms Reserve where he witnessed the discovery of the very first Chinook to be found at that restoration project.
Although eelgrass populations have declined in some parts of Puget Sound, overall numbers for the aquatic plant have remained steady ecosystem-wide, according to an analysis of 41 years of data from the Washington Department of Fish and Wildlife.
The study, published in the Journal of Ecology, was co-authored by Puget Sound Institute lead ecosystem ecologist Tessa Francis and was aided by a team of University of Washington student assistants who sorted through more than 160,000 notebook entries to parse out survey findings.
The data comes from long-time surveys of Pacific Herring, which also included the detailed observations of eelgrass abundance. (We first wrote about this treasure trove of hand-written notebooks in a PSI blog focusing on its implication for herring studies.) The paper was co-authored by a team of scientists from NOAA, PSI, Earth Resource Technology, The Nature Conservancy, WDFW and the University of Washington School of Environmental and Forest Sciences.
The researchers say the findings give some hope that eelgrass meadows may be more resilient than expected to pressures such as climate change, but they caution that sharp declines in some areas are a source of concern.
“The fact that eelgrass has been stable over the last 40 years tells you that things are probably not getting worse, but it doesn’t mean that things are good,” study co-author Phil Levin, of the University of Washington and The Nature Conservancy told the Seattle Times today.
PSI’s Francis was also quoted in the Seattle Times story and called the findings “promising in terms of recovery, because it’s a lot easier to think of what we might do on a local scale, than to think of what we might do on a grand, ecosystem scale.”
Eelgrass is an aquatic flowering plant that provides important habitat for young salmon, herring, Dungeness crabs and many other species. You can read about efforts to restore eelgrass beds in Puget Sound in our magazine series Salish Sea Currents.
In early 2016, scientists at NOAA made headlines when they reported finding 81 different man-made chemicals in the tissues of juvenile chinook salmon in Puget Sound. Among those chemicals were drugs such as cocaine and Prozac.
This was the first time scientists had made these findings for the region’s salmon, but it has been well-understood that marine waters the world over are becoming an alphabet soup of rogue chemicals. In varying degrees, these chemicals are settling into the bodies of every species analyzed in Puget Sound, including humans.
Many are pharmaceuticals that pass through sewage treatment plants. Others, such as flame retardants (also known as PBDEs) can bind to the dust and blow out to sea. Some simply persist in the environment and pass through the food chain. Often these chemicals occur in vanishingly small traces, sometimes in the parts per trillion.
The big question, scientists say, is not whether these chemicals are in the environment, but which of them are the most dangerous. Could something in such trace amounts cause harm? And what happens when more than four million residents of the region all contribute to the problem?
That is the topic of our latest story in Salish Sea Currents. Christopher Dunagan reports on some of the effects of chemicals known as contaminants of emerging concern. The story covers a range of contaminants, from pharmaceuticals like Prozac and birth control to industrial chemicals. Some of the findings are surprising — tiny amounts of birth control in the water can actually change the sex of some fish species — and in other cases the ramifications are unknown but potentially disturbing. Take a read and you will never look at wastewater and our chemically-dependent culture the same way.
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.
As world leaders meet this week in Paris to discuss global climate change, a new report from the University of Washington looks at expected climate impacts in the Puget Sound region. Christopher Dunagan wraps up his three-part series on the report’s findings with a focus on the region’s species and habitats.
Puget Sound’s shifting climate may mean big changes for the region’s farmers, according to a new report commissioned by the Puget Sound Institute. New patterns of droughts and floods, along with changes in the growing season will influence the way crops are grown — and even the types of crops that thrive in the region. Christopher Dunagan brings us part two of our series on the report’s findings.
