The Salish Sea may be a giant ‘practice room’ for humpback whales as they get ready to sing in their winter breeding grounds in Hawaii and Mexico. A network of hydrophones is recording it all.
Were the islands half full of auklets or were they half empty? One scientist offers an insider's view of a newly published study of two Pacific seabird colonies. He says having good data for the paper was key, but finding the right title didn't hurt.
About the magazine
Welcome to Salish Sea Currents, an online magazine founded in 2014 featuring stories about the science of ecosystem recovery. We are published by the University of Washington Puget Sound Institute (PSI) with major funding from the Environmental Protection Agency.

It’s hard to overstate the importance of mathematical models to science. Models show how planets move and how diseases spread. They track the paths of hurricanes and the future of climate change. Models allow scientists to look at systems or scenarios that they could never view otherwise. Increasingly, they are also helping scientists understand the Salish Sea. In this seven-part series, Christopher Dunagan reports on how computer models are changing the way we study the ecosystem.

Nearly half of the invasive species in Puget Sound's marine waters have been found within the last 20 years. Among the most common pathways for invaders are ships and boats that may carry thousands of tiny hitchhikers. Our series looks at this growing threat and some of the species of top concern.

Following dam removal, migratory salmon and other anadromous fish have been free to swim into the upper Elwha for the first time in 100 years. Their actual behaviors and reproductive success may well be driven by changes in their genetic makeup.
Scientists are reporting a decline in oxygen-rich waters throughout the world, raising concerns for sea life. In parts of Puget Sound, low oxygen levels can occur naturally but may be worsened by human-caused pollution. In this five-part series, Christopher Dunagan reports on the critical nature of oxygen to Puget Sound species. Scientists are finding that changes in oxygen levels can lead to physiological adjustments, shifts in predator-prey relationships and other repercussions throughout the food web. Read the latest story.
This three-part series explores opportunities and challenges of using medical interventions to save Puget Sound's southern resident orcas from extinction. Part 1 looks at how scientists might treat endangered southern resident orcas that face starvation and risks of disease; Part 2 considers how veterinarians have intervened with other animals in the wild, and how this might apply to orcas in Puget Sound; and Part 3 explores a federally approved vaccination program designed to ward of a deadly virus among endangered Hawaiian monk seals.
A series covering major science themes presented at SSEC16 in Vancouver, BC. Sponsored by U.S. EPA and the Salish Sea Ecosystem Conference.

An in-depth series on issues related to shoreline armoring in the Puget Sound region. Sponsored by U.S. EPA and Washington Department of Fish and Wildlife.
Salish Sea Currents presents an in-depth series focusing on shoreline armoring in the Puget Sound region. Close to a third of Puget Sound's shoreline is classified as armored with bulkheads and other structures meant to hold back storm surge and erosion. But new studies reveal the often significant toll this is taking on the environment. To be notified of new Salish Sea Currents stories, subscribe to the Puget Sound Institute eNews.
A 10-story series covering major science themes presented at SSEC14 in Seattle, WA. Sponsored by U.S. EPA and the Puget Sound Partnership.
In this first Salish Sea Currents series, we offer 10 stories exploring major research themes presented during the 2014 Salish Sea Ecosystem Conference.
New EPA-funded Implementation Strategies are designed to target Puget Sound recovery in the most direct and coordinated way ever conducted by state and federal agencies. We report on how these strategies will affect Puget Sound’s Vital Signs for years to come, and why you should care (a lot).
