Rainfall in May was extremely low: The third lowest amount ever recorded. Rivers are responding differently depending upon whether they received water from rain or snow, which is melting rapidly. With projected drier and warmer conditions, can the remaining snowpack maintain healthy streamflows this summer? Seawater is already getting saltier than normal in response to the lack of rain. We see algal blooms in many colors. What is that orange stuff out there? It’s a Noctiluca bloom and organic material drifting at the surface stretching from South to Central Sound and Whidbey Basin.

Kids around the region are learning about the Salish Sea thanks to a new book that is being offered — in many cases free of cost — to Washington schools and libraries. Explore the Salish Sea by Joe Gaydos and Audrey Benedict inspires the next generation to appreciate and perhaps someday protect the environment close at hand.
A high-profile salmon escape led to a ban on salmon farms in Washington earlier this year. But just across the border, scientists say salmon farms in British Columbia expose migrating fish from Puget Sound to potential maladies like parasites, bacteria and dangerous viruses. They say simply getting rid of salmon farms in Washington does not put the potential impacts to rest.
A report from the Washington State Department of Health outlines results from a series of projects funded by the U.S. Environmental Protection Agency's National Estuary Program in 2011. These projects addressed pathogen pollution in Puget Sound through the management of human and animal waste. Restoring shellfish growing areas, avoiding shellfish closures, and protecting people from disease served as the primary objectives.
The U.S. Environmental Protection Agency awarded a Five-year Puget Sound Tribal Capacity Program grant (Grant #PA-00J27701) to the Skokomish Indian Tribe. The tribe received approximately $1 million over a five-year project period (10/1/2010-9/30/2015). The purpose of the Puget Sound Tribal Capacity Program is to assist Puget Sound tribes in participating in the development and implementation of the Puget Sound Action Agenda.
A report from the Northwest Indian Fisheries Commission describes the results of a series of 97 tribal projects related to Puget Sound recovery funded by the Environmental Protection Agency.
In December 2005, Washington Governor Christine Gregoire outlined an ambitious vision for Puget Sound. She appointed 21 leaders, including representatives from building and timber industries, shellfish growers, agriculture and environmental interests, port authorities, and local, state, federal, and tribal governments to the Puget Sound Partnership. The Partnership was given a 10-month assignment to “develop recommendations for preserving the health and ecosystem of Puget Sound, and to help educate and enlist the public in achieving recovery of the Sound by 2020.” The report was published in December 2006.
Ocean acidification may be twice as extreme in Puget Sound’s seagrass habitats, threatening Dungeness crabs
Ocean acidification could be up to twice as severe in fragile seagrass habitats as it is in the open ocean, according to a study published last April in the Proceedings of the National Academy of Sciences. The conditions may threaten Dungeness crabs by 2050 and will be especially pronounced in the winter, the study says.
Pacific herring exposed to stormwater in Puget Sound show some of the same effects as fish exposed to major oil spills. Symptoms include heart and developmental problems.
New studies show that eelgrass wasting disease is more common in warmer waters, leading to concerns over the future effects of climate change on eelgrass populations in Puget Sound. We continue our series on science findings from the 2018 Salish Sea Ecosystem Conference.
Genetic testing shows that invasive European green crabs in Puget Sound likely did not come from the Sooke Basin in British Columbia as previously thought. New findings on the crab's origins were presented at the 2018 Salish Sea Ecosystem Conference in Seattle.
State agencies tracking pollution levels in Puget Sound have discovered traces of oxycodone in the tissues of native bay mussels (Mytilus trossulus) from Seattle and Bremerton area harbors. The findings were presented at the 2018 Salish Sea Ecosystem Conference in Seattle.
Kelps are large seaweeds in the order Laminariales that form dense canopies in temperate rocky intertidal and subtidal habitats less than 30 m in depth. The kelp flora of the Pacific Northwest is one of the most diverse in the world.
Scientists are trying to learn how to restore Puget Sound’s diminishing kelp forests in an effort to stave off habitat loss for rockfish and other threatened species. We report on new findings presented at the 2018 Salish Sea Ecosystem Conference in Seattle.
By March, regional impacts of large-scale climate patterns normalized, and air temperatures, precipitation, and coastal downwelling were below normal. April brought abundant rain and rivers responded. With La Niña returning to ENSO-neutral conditions, will the favorable snowpack maintain beneficial streamflows through summer? In 2018, water conditions in Puget Sound are mostly expected, except in Hood Canal where conditions only changed recently. Many rivers and field drainage ditches release sediment. A strong red-brown bloom is present in Sinclair Inlet, a bright- brown bloom in Padilla Bay (Joe Leary Slough), and a bright green bloom in Bellingham Bay. It is colorful out there! You might see our team on the water sampling sediments this month.
Bridging the gap between nature and technology might be a challenge for the Puget Sound region, but tech leaders could play an important role in protecting and restoring the ecosystem, according to a panel of experts at last week’s Salish Sea Ecosystem Conference in Seattle.
Gov. Jay Inslee joined former Interior Secretary Sally Jewell to open three days of science talks at the Salish Sea Ecosystem Conference in Seattle. The conference includes about 700 scientific presentations on topics ranging from orcas to habitat restoration, from climate change to toxic chemicals.
Large-scale climate patterns and local weather patterns are returning to more normal conditions. La Niña helped build a favorable snowpack, projected to persist well into spring due to cooler weather. As a consequence, stream flows are largely normal. In Puget Sound, we see again normal water conditions and observe early spring blooms in Central Sound, northern Hood Canal, and Whidbey Basin. Herring are spawning in Admiralty Reach and further north. Salmon Bay in Seattle continues to have frequent oil sheens on the water.
Sediment Quality in Puget Sound: Changes in chemical contaminants and invertebrate communities at 10 sentinel stations, 1989–2015
A 2018 report from the Washington State Department of Ecology presents results from 27 years of sampling sediments and benthic invertebrates at 10 long-term stations throughout the greater Puget Sound area every year from 1989 through 2015.
As the region's population grows, scientists say we can expect to see increasing amounts of nitrogen and other elements flowing into Puget Sound. Known as “nutrients” these elements are naturally occurring and even necessary for life, but officials worry that nutrients from wastewater and other human sources are tipping the balance. That could mean big problems for fish and other marine life, gradually depleting the water of oxygen and altering the food web.
A regional sewage-treatment system in Thurston County has helped contain low-oxygen problems in Budd Inlet as the population continues to grow. The system cleans up some of the effluent for replenishing groundwater supplies.
High amounts of elements such as nitrogen can cause blooms of phytoplankton that sometimes trigger perturbations throughout the food web. This occurs most often in the spring and summer after the long, dark, cloudy days of winter begin to fade.
The amount of oxygen in the Salish Sea is dependent on water circulation which distributes chemical elements such as nitrogen through the system.
Under the federal Clean Water Act, states are required to assess the quality of their surface waters and compile a list of polluted water bodies. The law mandates cleanup plans to address pollution and other water-quality problems. This article describes how this process works in Washington state for dissolved oxygen.
Daily and annual habitat use and habitat-to-habitat movement by Glaucous-winged Gulls at Protection Island, Washington
A 2017 paper in the journal Northwestern Naturalist looks at distribution patterns for Glaucous-winged Gulls across associated habitats in the Salish Sea.
As wildlife managers work to recover Puget Sound’s diminished Chinook population, a proposed white paper is expected to review the impacts of some of the salmon's chief predators. The study would include a section on potential management of seals and sea lions, prompting open discussion of a long taboo subject: Could officials seek to revise the Marine Mammal Protection Act — or even conduct lethal or non-lethal removal of seals and sea lions in some cases? Such actions are hypothetical, but we look at some of the ongoing discussions around the issue as prompted by a new resolution from the Puget Sound Leadership Council.
A December 2017 article in the journal PLOS One reports that incidents and violations among whale watching vessels have increased in the Central Salish Sea since 1998.
The Washington Marine Resources Advisory Council has released an addendum to the 2012 report Ocean Acidification: From Knowledge to Action. The original report established a statewide strategy for addressing ocean acidification in Washington. The addendum identifies updates based on emerging science and management practices and is intended to be a companion to the 2012 report.
Sea lions living along the coast of Washington are at risk from harmful algal blooms throughout the year, according to a 2017 study published in the Marine Ecology Progress Series.
Group characteristics, site fidelity, and photo-identification of harbor porpoises, Phocoena phocoena, in Burrows Pass, Fidalgo Island, Washington
A 2017 paper in the journal Marine Mammal Science examines harbor porpoise group structure and site fidelity in the Salish Sea.
The Puget Sound Ecosystem Monitoring Program has released its sixth annual Marine Waters Overview. The report provides an assessment of marine conditions for the year 2016 and includes updates on water quality as well as status reports for select plankton, seabirds and fish.
