The Salish Sea is changing – but understanding how and why requires looking beneath the surface. In this talk, Greig Oldford will introduce how ocean computer models, including the NEMO-HOTSSea model, can help reconstruct past ocean conditions such as temperature, currents, and mixing. He will then show how these physical changes connect to zooplankton – the tiny drifting animals that form a critical link between plankton and fish, including salmon. Using recent modelling work in the Strait of Georgia, the talk will explore how long-term ocean data can help us understand shifting marine food webs and better anticipate ecological change.
