Our story last week about the impacts of predators on chinook salmon populations in Puget Sound continues to gather strong interest from our readers. Several thousand viewed it after it came out last Thursday, and it was reprinted in the Kitsap Sun on Monday.
The story was written by PSI senior writer Christopher Dunagan and reports on a new study showing that area seals and sea lions are eating a much higher amount of threatened chinook than previously known. Many questions still remain, but it is the first time that a peer-reviewed study has attempted to quantify these predator impacts to such a degree and in such detail.
Here are a few highlights: As many as one in five young chinook are eaten before they can make it out of Puget Sound into the open ocean. Area seals and sea lions eat twice as many chinook as do Puget Sound’s endangered orcas, and six times the annual commercial and recreational catches from local fishermen combined. Scientists attribute the large numbers to an increase in seals and sea lions since the 1970s after the animals were protected under the Marine Mammal Protection Act.
Not surprisingly, scientists and policymakers will have to look more closely at these numbers to determine what to do. Seals and sea lions are rightly protected, and old (and undesirable) policies of hunting the animals to protect salmon are not an option. Scientists say that even if such policies were possible, there is no saying that they would actually protect the salmon population.
The fact is that the seals and sea lions are just doing what they do naturally, and while their populations are healthy, there aren’t necessarily more of them than there should be. Some would argue that this study is a reminder that we need to continue to recover habitat and create better conditions for the salmon to withstand what are essentially normal pressures from the environment. Historically, Puget Sound’s chinook and predators co-existed just fine, but that was before millions of humans started destroying the local streams and floodplains, degrading beaches and polluting the water. See a harbor seal with a salmon in its mouth? That can also be seen as a sign of Puget Sound’s health.

This year has been as busy as any we have had since our founding in 2010. As we look forward to year seven (!) of our organization, we have put together a sort of highlight reel of accomplishments.
At various points, PSI scientists worked to prioritize emerging contaminants in our waterways. We studied the health of forage fish populations, analyzed eelgrass abundance and brought together key scientific findings for Puget Sound’s marine and nearshore.
Most recently, our team began helping to develop new state and federal Implementation Strategies that will prioritize future Puget Sound cleanup efforts (you can read more about the Implementation Strategies in the Encyclopedia of Puget Sound).
Through it all, we have kept you informed with dozens of articles in our magazine Salish Sea Currents, as well as many new papers in scientific journals. After a strong 2016, we believe that science is more vital than ever to Puget Sound recovery. We look forward to building on our accomplishments in 2017.

Marine Waters 2015 report cover
The Puget Sound Ecosystem Monitoring Program released its fifth annual Marine Waters Report today. The report provides an assessment of marine conditions for the year 2015 and includes updates on water quality as well as status reports for select plankton, seabirds, fish and marine mammals.
According to the report, water temperatures broke records throughout Puget Sound. The year was also the worst on record for two distinct stocks of Pacific herring. You can read the full report on the Puget Sound Partnership website.

Puget Sound Institute Director Joel Baker was interviewed by the The News Tribune in Tacoma this week as part of the paper’s coverage of climate change in Puget Sound. The article features a new University of Washington report commissioned by the Puget Sound Institute that provides the most comprehensive look to date at expected climate impacts in the region.
New Puget Sound climate study: Older projections coming true, more changes ahead
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.

A new report commissioned by the Puget Sound Institute and the Encyclopedia of Puget Sound provides the most comprehensive assessment to date of the expected impacts of climate change on the Puget Sound region.
The report was produced by the University of Washington Climate Impacts Group, and is meant as an easy-to-read summary that covers topics such as increasing landslides, flooding, sea level rise, impacts on human health, agriculture and rising stream temperatures for salmon. Partners in the report include NOAA, The Nature Conservancy, the Puget Sound Partnership, the WWU Huxley Spatial Institute and others including dozens of contributing scientists. Major funding for the report was provided by the Environmental Protection Agency.

Landslides, which all too often kill people, destroy homes and disrupt transportation networks, could increase in the coming years as a result of climate change. A new report commissioned by the Puget Sound Institute looks at what we might expect in the region, especially during the winter months when rains and flooding reach their peak. PSI senior writer Christopher Dunagan brings us part one of a three-part series on some of the report’s findings.
The 2015 State of the Sound report from the Puget Sound Partnership points to lack of funding as one of the leading barriers to Puget Sound recovery. The report looks at ongoing progress to restore the health of the ecosystem, but according to the Partnership’s Executive Director Sheida Sahandy, “The rate at which we as a community are continuing to damage Puget Sound is greater than the rate at which we are fixing it.”
Overall, funding has fallen far short of critical needs, the report argues. Projects described in the state’s recovery plan as ‘Near Term Actions’, would have required $875 million to carry out during the years 2014 – 2015, but as of last June had received only $67 million. The period from 2012-2013 had a shortfall of 57%.
The State of the Sound also describes a lack of significant progress on several key areas of focus for state and federal recovery efforts. The agency tracks a series of ‘Vital Signs’ such as numbers of orcas or fluctuations in herring populations—there are 21 vital signs in all—as indicators of Puget Sound health. “The majority of Vital Sign indicators are, at best, only slowly changing. Few are at—or even within reach of—their 2014 interim targets,” reads the report.
Some vital signs have seen modest improvement, however. The Partnership says that in 2014 removal of shoreline armoring such as seawalls and bulkheads exceeded permits for new armoring structures. Goals for habitat restoration also made some steps forward.
The State of the Sound report includes a series of funding recommendations ranging from continuation of existing allocations to support of legislation that would direct additional funds to key areas like habitats, stormwater and restoration of shellfish beds.

Microplastics in the Ocean: A Global Assessment
Our Director Joel Baker recently co-authored Microplastics in the Ocean: A Global Assessment, an international report commissioned by GESAMP (The Joint Group of Experts on Scientific Aspects of Marine Environmental Protection). GESAMP is an inter-Agency Body of the United Nations, comprised of a group of independent scientists providing advice to UN Agencies on a wide variety of ocean matters. The report examined the global distribution of micro plastic particles, their known and hypothesized effects on marine organisms, and evaluated potential solutions.

Before it was SSEC14, it was the Puget Sound Research Conference. It was 1988, the cold war was still in swing and researchers in Seattle were gathering for the very first science conference dedicated to the waters of Puget Sound.
