In June we observed a widespread Noctiluca bloom in Central Puget Sound, evident by bright orange streaks in the water. Noctiluca blooms in Puget Sound have lasted much longer and occurred on a much larger scale than in previous years.

A new field guide brings together detailed accounts and illustrations of 260 species of fish known to occur in the Salish Sea. This review from EoPS editorial board member Joe Gaydos was originally published on the SeaDoc Society website. 

This article is the latest in a series about computer models and their uses within the Puget Sound ecosystem. Today, we look at the Salish Sea Model, one of several models in the region helping to predict water circulation, water quality and food-web relationships.

Tufted puffins have become an increasingly rare sight in the Pacific Northwest. Biologist and writer Eric Wagner recently visited Puget Sound's Smith Island, home to one of the region's last surviving colonies of these colorful seabirds. 

All across the region, communities are finding that rising seas and rising rivers are two sides of the same coin. New research funded by the Environmental Protection Agency may help managers target their responses to climate-fueled flood risks in Puget Sound. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.

Beavers provide critical benefits for wetland ecosystems but can also alter the landscape in ways that are unpredictable for property owners and conservationists alike. New techniques are helping humans and beavers share the landscape with the goal of benefiting both parties. The following article was commissioned by the Habitat Strategic Initiative Lead (HSIL), a cross-agency team co-led by the Washington Departments of Fish and Wildlife and Natural Resources.

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.

A 2023 report from the Puget Sound Ecosystem Monitoring Program presents an overview of selected recent monitoring and research activities focused on toxic contaminants in the Salish Sea. 

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.
