Southern Adventist University is affiliated with Walla Walla University's Rosario Beach Marine Biological Station to enrich and supplement its on-campus programs.
This Marine Biological Station is located on Fidalgo Island in the Puget Sound in the state of Washington and provides students with opportunities to study marine habitats in a temperate climate. This station also furnishes facilities for summer class work and research. Its close proximity to biomes ranging from sea bottom to Alpine tundra provides an excellent opportunity for instruction and investigation.
