The Great South Australian Coastal Upwelling System is a seasonal upwelling system in the eastern Great Australian Bight, extending from Ceduna, South Australia, to Portland, Victoria, over a distance of about. Upwelling events occur in the austral summer (from November to May) when seasonal winds blow from the southeast. These winds blow parallel to the shoreline at certain areas of the coast, which forces coastal waters offshore via Ekman transport and draws up cold, nutrient - rich waters from the ocean floor. Because the deep water carries abundant nutrients up from the ocean floor, the upwelling area differs from the rest of the Great Australian Bight, especially the areas offshore of Western Australia and the Nullabor in South Australia, which are generally nutrient - poor. Every summer, the upwelling sustains a bountiful ecosystem that attracts blue whales and supports rich fisheries. The Great South Australian Coastal Upwelling System (GSACUS) is Australia's only deep - reaching coastal upwelling system, with nutrient - enriched water stemming from depths exceeding. Recently, a new upwelling centre has been discovered on the western shelf of Tasmania. Since this new upwelling centre is located outside South Australian waters, the entire upwelling system should be rather called the Great Southern Australian Coastal Upwelling System.
