Salish Sea Currents magazine

Each spring, about a dozen gray whales make a brief detour into the Salish Sea before heading north to their feeding grounds in the Arctic. Biologists dubbed these whales "Sounders" after first noting their presence in the 1990s, and the whales have become rare but widely anticipated visitors to local waters. The whales were spotted again this year, but biologists have documented a 24 percent decline in gray whale populations along the West Coast.

A 2021 paper in the journal PLoS ONE provides a clearer picture of what endangered southern resident orcas eat throughout the year. Chinook salmon make up the bulk of the whales' diet, but the paper suggests that other salmon species and non-salmonid fishes can also play important roles depending on the season.

The recently approved HEAL Act requires the state of Washington to address issues of environmental justice within its agencies. The Act is expected to be signed by the governor and focuses on inequities in environmental health conditions for disenfranchised populations.
