Durban Eddy

From Openwaterpedia

Durban eddy is a lee-trapped, semi-permanent, cold core cyclonic eddy that occurs off the east coast of South Africa south of Durban. It is driven by the Agulhas Current which moves offshore of a regressing shelf edge south of Durban. The eddy draws cold water upward, which is nutrient-rich compared to surrounding waters, facilitating biological production. The eddy is a mesoscale feature, extending approximately 60-90 km alongshore and 30-50 km offshore.
