Responding to oil spills in Puget Sound: A guide for volunteers

A state law going into effect this month will significantly increase funding for the cleanup of abandoned and derelict vessels in Puget Sound. The funding will add about $4.3 million annually to remove hazardous sunken wrecks and related pollutants.

We are in a weakening La Niña, coastal downwelling has lessened and we are getting out of a cold and wet stretch, hurray. In March, rivers have almost returned to normal and carry clear water. It’s a good time to go diving if you don’t mind cold water. The productive season has only started in some places and patches of jellyfish are visible. Have a look at this edition and marvel about the secrets of the dead, or mysterious sediment clouds and the oil sheen spotted near Lummi Bay.

After a relatively warm summer and fall, and La Niña forming in the tropics, stream flows in the Puget Sound region are now relatively normal. Summer in Puget Sound produced lots of algal and organic material in the water and on beaches, which by October have disappeared. Kelp beds look strong in northern Puget Sound and the Straits; and the harvest of the annual chum salmon run is in full swing in Hood Canal. Jellyfish aggregations are visible in Budd and Sinclair Inlets — and some of the jellyfish might conceal a beast of another kind within. Oil sheens on the water are currently numerous.

Scientists are still trying to understand what caused the deaths of thousands of rhinoceros auklets in the Salish Sea in 2016. Some studies point to disease as a central factor in that incident and potentially other large seabird die-offs along the coast. That is prompting a deeper look at what makes these birds sick, and how local populations are faring. We followed a group of researchers as they gave a health checkup to a breeding colony of rhinoceros auklets on Protection Island.

The Toxics in Fish Implementation Strategy is a recovery plan that will guide funding and activities to reduce the impacts of toxics contaminants on marine fish and the humans that consume them. A final version of the plan was published in May 2021.

Bills in the state legislature target oil spill threats to Puget Sound and its endangered killer whales.

An EPA-funded study of oil spill risks in Puget Sound forms the basis of new legislation to regulate vessel traffic in the region. We break down some of the numbers from the study and look at where the risks may be greatest.

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.  

A 2017 report from the University of Washington summarizes current scientific knowledge on chemical oil spill dispersants and their potential impacts on shoreline habitats in San Juan County, Washington. 

A July 2016 report from the University of Washington Puget Sound Institute summarizes and reviews 10 EPA-funded projects focusing on Puget Sound's marine and nearshore environments. The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program.  The report is an analysis of findings on invasive species, toxics, oil spill, and integrated risk assessment.

A 2015 paper in the journal PLoS ONE identifies ongoing and proposed energy-related development projects that will increase marine vessel traffic in the Salish Sea. It evaluates the threats each project poses to natural resources important to Coast Salish first nations and tribes.
