An Environmental Education Organization Promoting Estuary Education & Protection of the Puget Sound The Puget Sound Estuarium was founded by the South Sound Estuary Association (SSEA) in 2007. We encourage community members to EXPLORE animals and plants in their local estuaries, where freshwater and saltwater meet. We CONNECT people of all ages to what is unique about this delicate, vibrant ecosystem. Our educational opportunities INSPIRE individuals to take better care of our shared natural resources. Our vision is to create an educated community that is engaged and inspired to promote the health, conservation and restoration of Puget Sound. Our mission is to foster learning opportunities that inspire people of all ages to connect with, protect, and enjoy the unique estuary environment of south Puget Sound.
