Upwelling is a process by which cold, low-oxygen, low-pH, nutrient-rich water from the deep Pacific Ocean is drawn onto the continental shelf in response to shifts in the large-scale winds. The pathways of upwelled water across the continental shelf, the timing of its arrival at the coast, and how mixing modifies its properties have consequences for coastal ecosystems. Climate projections suggest changes in upwelling, with impacts that will vary regionally. The project’s overall objective is to determine how seasonal upwelling affects nutrient availability that supports high levels of plankton productivity along the BC central coast.
