Eddies enclose warm and salty Mediterranean water

Please scroll down for video

The high rate of evaporation in the Mediterranean Sea leads to a significantly large salinity in that basin when compared with the Atlantic. The salty and relatively warm Mediterranean Water flows through the Strait of Gibraltar and afterwards along the Iberian Peninsula into the northeast Atlantic. At an intermediate depth (800-1200m), it flows over a complex system of underwater canyons and promontories. In the course of this, strong eddies separate from the main flow and spread into the ocean interior.

The film shows the Mediterranean Water eddies (meddies for short) wandering through the ocean (violet/blue) while rotating clockwise and enclosing the salty and warm water, keeping it over several years. During their movement, the meddies are influenced by other oceanic eddies (shown in green), whose rotation sense is counterclockwise. Due to the interaction, the meddies modify their translation direction, sometimes start to wobble and can eventually loose their stability and be destroyed.
