Coastal upwelling is the best known type of upwelling, and the most closely related to human activities as it supports some of the most productive fisheries in the world. Coastal upwelling will occur if the wind direction is parallel to the coastline and generates wind-driven currents.
Ekman transport leads to coastal upwelling, which provides the nutrient supply for some of the largest fishing markets on the planet [15] and can impact the stability of the Antarctic Ice Sheet by pulling warm deep water onto the continental shelf.
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 800 kilometres (500 mi). Upwelling events occur in the austral summer (from November to May) when seasonal winds blow from the southeast.
The upwelling further cools the already cool California Current. This is the mechanism that produces California's characteristic coastal fog and cool ocean waters. As a result, ocean surf temperatures are much colder in summer along the Pacific coast than the Atlantic coast at the same latitude.
Upwelling behavior: One of the unique characteristics of the Somali Current is the presence of strong coastal upwelling - the only major instance of this happening at a western ocean boundary. Following Ekman transport and with the southwest monsoon blowing parallel to the Somali coastline, the upwelling direction is to the offshore during the ...
Coastal upwelling of the South Eastern Arabian Sea (SEAS) is a typical eastern boundary upwelling system (EBUS) similar to the California, Bengulea, Canary Island, and Peru-Chile systems. Unlike those four, the SEAS upwelling system needs to be explored in a much focused manner to clearly understand the chemical and biological responses ...
Coastal upwelling is the main factor contributing to the high biological productivity of the Humboldt current. [1] Upwelling within the current is not uniform across the entire system. Three notable upwelling subsystems are produced by this current:
While upwelling promotes abundant primary and secondary production in the upper parts of the water column and near the coast, deeper waters with limited oxygen exchange create hypoxic areas called oxygen minimum zones at the coastal shelf and upper coastal slope. The Benguela oxygen minimum zone starts around a depth of 100 m and is a few ...
