Plankton activate Puget Sound marine life. They form the base of the food web that scales up to larger, iconic megafauna including salmon and killer whales. Place is important, even in oceanic real estate. So is timing. Seasonal changes in Puget Sound chemistry and physics result in spatial and temporal patchiness, creating micro-neighborhoods within the larger scope of the Pacific Northwest marine environment, and an elusive ‘now you see ‘em, now you don’t’ pattern for hungry predators.
