Knowing the cause of sea star wasting disease allows scientists to look for ways to increase resilience among the ravaged sea star population.

The Washington State Department of Ecology and other state natural resources agencies have divided the Washington into 62 "Water Resource Inventory Areas" or "WRIAs" to delineate the state's major watersheds.

Crab Team members maintain a massive surveillance program to track the population’s advance, while researchers probe the inner workings of the invasive species.

Research on the sounds and feeding behavior of Puget Sound's southern resident orcas is providing new insight into how the whales respond to underwater noise. A recent online conference brought together some of these findings along with discussions on how to reduce the impacts of noise from vessel traffic.

In recent decades, hundreds of millions of dollars have been spent to restore habitat for Puget Sound salmon. In this article, we look at how scientists are gauging their progress. Are environmental conditions improving or getting worse? The answer may depend on where you look and who you ask.

Tidal wetlands are crucial to Chinook salmon recovery but are among the most threatened habitats in Puget Sound. In 2012, The Nature Conservancy began restoring a 150-acre section of tidal marsh on Port Susan Bay at the mouth of the Stillaguamish River. That project is entering a new phase and may soon connect with other adjacent restoration efforts put forth by the Stillaguamish Tribe.

As the plight of Puget Sound’s southern resident orcas becomes increasingly desperate, with the population dropping from 98 to 75 in just 22 years, scientists are weighing the options of medical intervention. In part two of our two-part series The Orca Docs we look at how veterinarians have intervened with other animals in the wild, and how this might apply to the situation here in Puget Sound.
