New Seattle seawall improves migratory pathway for young salmon

Design innovations at the new seawall along Seattle's waterfront could inspire improvements for other shoreline structures around Puget Sound. They may even encourage broader regulatory changes that enhance habitat for migrating salmon and other species.

Delicious and now endangered: Can the pinto abalone make a comeback?

The pinto abalone was a popular sport catch for divers in the Salish Sea until its numbers plummeted to near extinction. Now, the marine snail is on the endangered species list and the focus of an ambitious hatchery and replanting program. A broad coalition of partners has released more than 20,000 young pintos into the wild with the hope that the population will start to rebound.

Search for invasive green crab continues during pandemic

The state's stay-at-home order has halted much of the field research that would normally be underway in Puget Sound this spring, but a small group of scientists and volunteers have been able to continue their search for an invading marauder along the shoreline. Their work has been classified as critical by the state.

Causes of mortality in a harbor seal (Phoca vitulina) population at equilibrium

A 2020 article in the journal Frontiers in Marine Science looks at harbor seal stranding and necropsy findings in the San Juan Islands to assess age-related stranding trends and causes of mortality. The harbor seal (Phoca vitulina richardii) population in the Salish Sea has been at equilibrium since the mid-1990s. This stable population of marine mammals resides relatively close to shore near a

Fire danger returning to Western Washington

Historically, the eastern part of the state has seen the largest impacts from fires, but climate change is now increasing the risk west of the Cascades. That could have big implications for many rural communities throughout Western Washington, including those in the Puget Sound region.

Salish Sea Currents special climate issue

Welcome to the 2020 edition of Salish Sea Currents magazine. This is the fourth issue of the magazine, and the first one dedicated to a single theme. All of the stories in this report address the impact of climate change on the Salish Sea ecosystem.
In 2014 and 2019, sea surface temperatures across a broad area warmed to well above average (0 in the middle of the key). On map, 3° C = 5.4° F // Map: NOAA Fisheries

Warm-water ‘blobs’ significantly diminish salmon, other fish populations, study says

It’s no secret that salmon and other Northwest fish populations are expected to shrink as a result of a warming Pacific Ocean. But a new study suggests that the resulting decline in commercial fishing by 2050 could be twice as great as previously estimated by climate scientists.

Nooksack River Transboundary Technical Collaboration Group 2018-2019 annual report

The Nooksack River watershed spans part of the border between British Columbia and the State of Washington. In August 2018, the international, multi-agency Nooksack River Transboundary Technical Collaboration Group was established to implement a three-year work plan to reduce fecal bacteria concentrations in the Nooksack River watershed. As a work plan deliverable, the group produced this annual

Voices Unbound: Enviro-Amplify

What do people really mean when they talk about the environment? A new podcast asks regular citizens a simple, but charged question: "What are the environmental challenges that are most important to you?" The answers to that question drive this engaging podcast in sometimes unexpected directions, from the environmental impacts of being homeless, to air quality, to wide-ranging discussions about

Earth Day events go online because of virus

Participants in this year’s Earth Day activities won’t be rallying in large groups, participating in environmental festivals or coming together to clean up the Earth. On the 50th anniversary of Earth Day — April 21st — the environmental movement will be uniquely digital, with many people celebrating from their home computers.
