In late 2013, a marine heatwave that scientists dubbed “the blob” began warming the ocean throughout the Northeast Pacific, causing temperatures to rise almost 3°C above normal. The disruption severely depressed salmon returns. Whales, sea lions and seabirds starved, and warm water creatures were suddenly being spotted off the coast of Alaska. In Puget Sound, temperatures also jumped, but the effects of the blob […]

"> Science during the year of Covid: The Puget Sound Marine Waters Overview
While Covid restrictions remain a part of everyday life, a lot has eased since the global quarantines of spring 2020. During that time, the coronavirus effectively shut down scientific fieldwork in Puget Sound, leaving huge gaps in data for most facets of the ecosystem.

"> Recovery of Puget Sound species could hinge on better understanding of ecosystems
A recent report from the Puget Sound Partnership helps us understand the difficulty of restoring the Puget Sound ecosystem. What caught my attention in the State of the Sound report was that after 20 years of protecting and restoring streams, wetlands, shorelines and estuaries, we have not increased overall fish and wildlife populations, and some […]

"> Puget Sound fish and wildlife populations fall short of 10-year recovery goals
A final report on the 2020 ecosystem-recovery goals for Puget Sound outlines habitat improvements for some streams, shorelines and wetlands, but it also describes ongoing declines among fish and wildlife populations that use those habitats. The latest State of the Sound report, released this week by the Puget Sound Partnership, summarizes the status of 52 […]

Introducing DORA Explorer
Whether on land or in the sea, oxygen is critical for sustaining life. Healthy ecosystems depend on it, and the amount of dissolved oxygen in marine environments is one of the ways that scientists measure water quality. Both the research community and the regulatory authorities rely on complex computer models of the Salish Sea to […]

"> Conference highlights latest findings on toxic chemical in tires
The International Conference on Emerging Contaminants (EMCON), hosted virtually this month by the University of Washington, focused on newly identified threats from chemicals and microplastics in the environment. The conference provided an opportunity to hear the latest research on the discovery of a tire-related compound deadly to Puget Sound’s coho salmon. The cause of what scientists […]

"> Plunging into a jungle of weather statistics to find the footprints of climate change
“Augusts in Seattle are getting hotter, leading to a change of 3.5°F since 1970.” This was the sentence that caught my eye while reading an email from Peter Gerard, director of communications for Climate Central, an organization that prides itself on helping news reporters tell an accurate story of climate change. I wondered immediately: Is […]
