An ecosystem is defined by the physical space and the biology, including plants and animals, that live in that space. Different land ecosystems include forested mountains, grassy plains and dry deserts; marine ecosystems are just as diverse. In the Pacific Northwest, marine ecosystems range from the open ocean that is dominated by basin-wide forces, the coastal ocean that is influenced by seasonal upwelling events, and estuaries and bays that have both salt and freshwater flowing through them. All of these different marine ecosystems allow for a great diversity of habitats, which are necessary to support the many life stages of marine animals that call the Pacific Northwest home.
The dynamics of the coastal ocean in the Pacific Northwest are controlled and influenced by several regional- and large-scale factors that produce highly productive coastal and estuarine environments. The interaction of coastal currents with the contours of the ocean bottom and freshwater inputs from sources like the Columbia River and the Strait of Juan de Fuca, seasonal upwelling favorable winds that fuel phytoplankton blooms, and the south-flowing branch of the North Pacific Current, which moves water from Asia to North America, to form the California Current System, are some of the regional factors. Some of the important large-scale factors that shape our ecosystems are the Pacific Decadal Oscillation (PDO), which affects salmon survival in the ocean, and the El Niño Southern Oscillation (ENSO), which affects both ocean and weather conditions every 2-7 years.
