The Great Whirl is a huge anti-cyclonic eddy generated by the Somali current flowing in (northern) summer, and one of the two gigantic Indian Ocean Gyres (the other is the Socotra Gyre). The Great Whirl can be observed between 5-10°N and 52-57°E off the Somali coast in the summer season, a location typically around 200 km southwest of the ...
Both currents redistribute mass and heat along the stream current system along Madagascar's coast. [1] The North Madagascar Current flows into the South Equatorial Current just north of Madagascar and is directed into the Mozambique Channel, this connects to the gyre's equatorial currents into the Agulhas Current off the coast of Southeastern ...
Cyclonic eddies rotate anticlockwise (clockwise) in the Northern (Southern) hemisphere and have a cold core. Anticyclonic eddies rotate clockwise (anticlockwise) in the Northern (Southern) hemisphere and have a warm core. The temperature and salinity difference between the eddy core and the surrounding waters is the key element driving vertical ...
Direct evidence for these eddies has been found in satellite altimetry data, [1] ship borne surveys, [2] and moored current meter records. [3] These same current meter records, that were over two years in length, failed to show a strong, consistent current along the Mozambican coast, largely dispelling the notion of a steady Mozambique Current.
The East Madagascar Current is an oceanic flow feature near Madagascar.It flows southward from 20°S on the east side of Madagascar to the southern limit at Cape Saint Marie and subsequently feeds the Agulhas Current.
The Loop Current is an extension of the western boundary current of the North Atlantic subtropical gyre. [1] Serving as the dominant circulation feature in the Eastern Gulf of Mexico, the Loop Currents transports between 23 and 27 sverdrups [2] and reaches maximum flow speeds of from 1.5 to 1.8 meters/second.

These types of mesoscale eddies have been observed in many major ocean currents, including the Gulf Stream, the Agulhas Current, the Kuroshio Current, and the Antarctic Circumpolar Current, amongst others. Mesoscale ocean eddies are characterized by currents that flow in a roughly circular motion around the center of the eddy.
This water becomes the Agulhas Return Current, rejoining the Indian Ocean Gyre. It is estimated that up to 85 Sv (Sv) of the net transport is returned to the Indian Ocean through the retroflection. The remaining water is transported into the South Atlantic Gyre in the Agulhas Leakage. Along with direct branch currents, this leakage takes place ...
