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.
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.
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 ...
The world's largest ocean gyres. Western boundary currents may themselves be divided into sub-tropical or low-latitude western boundary currents.Sub-tropical western boundary currents are warm, deep, narrow, and fast-flowing currents that form on the west side of ocean basins due to western intensification.
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.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Near coastal zones, winds blowing parallel to the coast can generate wind-driven currents that create an Ekman transport away from the coast. [21] This moves the upper water mass away from the coast and leads to upwelling of cooler water from depth, [9] also termed coastal upwelling.
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 ...
