Upwelling intensity depends on wind strength and seasonal variability, as well as the vertical structure of the water, variations in the bottom bathymetry, and instabilities in the currents. In some areas, upwelling is a seasonal event leading to periodic bursts of productivity similar to spring blooms in coastal waters. Wind-induced upwelling ...
Computer models of ocean circulation increasingly place most of the deep upwelling in the Southern Ocean, associated with the strong winds in the open latitudes between South America and Antarctica. [28] Direct estimates of the strength of the thermohaline circulation have also been made at 26.5°N in the North Atlantic, by the UK-US RAPID ...
Where significant vertical movement of ocean currents is observed, this is known as upwelling and downwelling. The adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of seawater.
The Bonney Upwelling is the largest and most predictable upwelling in the GSACUS. It stretches from Portland, Victoria to Robe, South Australia.The continental shelf is narrow offshore of the "Bonney Coast" - only about 20 kilometres (12 mi) from the shore to the continental slope - and deep water is funneled to the surface through a series of submarine canyons.

Due to upwelling and downwelling, which are both wind-driven, mixing of different layers can occur through the rise of cold nutrient-rich and sinking of warm water, respectively. Generally, layers are based on water density : heavier, and hence denser, water is below the lighter water, representing a stable stratification .
