About the Encyclopedia

The Encyclopedia of Puget Sound is a free, open access website where scientists, policymakers and educators find and share information about the Puget Sound ecosystem. Read more about us.

Our scope

Puget Sound is fed by its many water sources, from high elevation snowmelt to floodplains and wetlands. Articles and accounts feature terrestrial species and environments, as well as nearshore and marine systems. View watershed boundaries.

Species Library

Puget Sound hosts more than 100 species of seabirds, 200 species of fish, 15 marine mammal species, hundreds of plant species, and thousands of invertebrate species. Find descriptions and photos in our Species Library.

Puget Sound Voices

Media: Puget Sound scuba pioneer

Puget Sound science owes a debt to the researchers and explorers who got there first. We profile some of these important figures in an occasional series we call Puget Sound Voices. This month, we feature Vern Morgas, one of Puget Sound's first scuba divers.

Prior to the 1940s, if you wanted to explore the waters beneath Puget Sound, you might have used a Jules Verne-style diving suit, complete with giant helmet and air tubes. Either that or you held your breath.
