Are the orcas starving? Scientists say it’s not that simple

The reported deaths this week of three more southern resident orcas have brought renewed urgency to efforts to save the critically endangered population of whales. Many scientists and policymakers are focusing on the orcas’ access to their main source of food, the Chinook salmon. Members of the orca population are appearing dangerously thin and malnourished.

Ancient harvests: A history of Salish Sea herring

If you were to ask a group of experts to make a list of culturally important foods in the Pacific Northwest, it would not be a surprise if salmon rose to the top.

Unsung seabirds could help track Puget Sound health

Pigeon guillemots have attracted relatively little scientific attention compared to other seabirds in Puget Sound. That may be because their population is generally stable, but a group of citizen scientists is helping to put guillemots on the conservation radar. They hope the birds can be used as an indicator of Puget Sound health. Eric Wagner reports for Salish […]

How did science fare in this year’s legislature?

By Jeff Rice There is no such thing as a general “science budget” for the state of Washington, but scientific research is meant to inform and catalyze many of the policies that govern Puget Sound recovery. There would be little understanding of how to protect Puget Sound’s beloved orcas without legions of scientists in the […]

Survey illustrates a lack of familiarity with the Salish Sea

Washington and British Columbia residents are largely unfamiliar with the Salish Sea. A recent study conducted by the SeaDoc Society and Oregon State University reveals a need to improve geographic literacy and familiarity with the Salish Sea among those communities who share and live alongside this integrated transboundary ecosystem. This is a guest blog from […]
