The Bonney Upwelling
BONNEY UPWELLING A clear explanation of this impressive natural phenomenon is provided at the bluewhalestudy site: "Driven by wind, the process of upwelling draws deep, nutrient-rich, cold water upwards toward the ocean's surface, replacing the warmer, usually nutrient-depleted, surface water. The nutrients in upwelled water are derived from marine organisms (both plant and animal) dying and sinking to the ocean floor. These nutrients are most abundant near coasts and river outlets, but may be conveyed by currents great distances along the ocean floor to be upwelled far from their source. When upwelled nutrients meet sunlight near the surface, minute phytoplankton (plant-like cells) 'bloom', turning the ocean green and providing a vital food source for a range of animals from krill (a type of zooplankton) to small schooling fish. These feed larger animals including rock lobster, giant crabs, fish (including commercial species), squid, seabirds, seals, dolph
