 Meddies are long-lived eddies (mainly anticyclonic) found in the North Atlantic Ocean containing water from the Mediterranean Sea, as they are formed due to the outflow Mediterranean currents. They are coherent vortices characterized by large salt and heat anomalies relative to their environment, typically these anomalies are of 0.4 - 1.1 g/kg and 2 - 4°C, respectively. Meddies usually have radii from 10 to 50 km, are 500 – 1000 m thick, and are found at depths of 1100 m. Most meddy observations come from the area of the Mediterranean Salt Tongue, as they are mainly created in two sites near the Strait of Gibraltar: Cape St. Vincent and Estremadura Promontory (see Figure 1). Every year, between 15 and 20 meddies are formed at these two sites, and there is a higher probability for meddy formation when the undercurrent speed is high. Meddies can survive for many years and can move through thousands of kilometers, thus they constitute a principal means by which ocean tracers are transported. Their open ocean decay is very slow, while topographic interactions appear to be the main decaying cause of meddies. These interactions are significant to the maintenance of the Mediterranean Salt Tongue, indeed studies estimate that meddies inject 25 - 50\% of the salt anomaly necessary to sustain the Mediterranean Salt Tongue.
