| Mesoscale eddies are frequently observed ocean processes at the shelf edge of the Black Sea. Remotely sensed high-resolution chlorophyll a and altimetry data have been used to investigate the development and migration of the mesoscale eddies in the northwestern Black Sea, along with a 3D circulation model output in this study. More than 15,000 eddies of different signs were identified in 2002–2010, with 53% of them appearing from March to July. During these periods, eddy-induced exchange accounts for 16%–31% of the total cross-slope volume transport at the upper layers shallower than 20 m. About volume of northwestern-shelf water was renewed by a single mesoscale eddy over the period 5 May to 20 July 2005, which is equivalent to 30.9% of the overall volume of shelf water |
