| dc.description.abstract | The influx of Mediterranean Water through the Strait of Gibraltar significantly influences the Northeast Atlantic. This inflow gives rise to distinctive oceanographic features known as Mediterranean Water Eddies (Meddies), which are characterized as deep, anticyclonic lenses of warm, saline water. During the R/V Knorr cruise KN207-03, conducted from the Azores to Iceland in the summer of 2012 as part of the international NA-VICE project, a meddy was identified at 41.3◦N, 27.1◦W. Its main physical properties were determined using in situ measurements from a Conductivity-Temperature-Depth (CTD) profiler and an Acoustic Doppler Current Profiler (ADCP). The meddy exhibited salinity and temperature anomalies of 0.26 and 2.4◦C, respectively, along with azimuthal velocities reaching 0.38 m s − 1 . These characteristics were compared with established criteria from previous studies to confirm that the observed feature – located further north than most previously documented meddies – met the classification requirements. At the time of the cruise, a cyclonic eddy exhibiting Mediterranean Water characteristics was detected north of the meddy. The analysis suggests that these features interacted, resulting in trapping of Mediterranean Water beneath the cyclone. The meddy sea surface expression was examined using altimetry data combined with an eddy detection algorithm, revealing a Sea Level Anomaly of 14 cm and a radius of 57 km. Additionally, altimetry and Argo data were used to reconstruct the meddy trajectory, indicating that it originated in the Irish continental shelf. This finding supports the hypothesis that meddies can form north of the Iberian Peninsula, as far as the extension of the Mediterranean Outflow. | eng |
