The paper presents the results of quasi-synchronous satellite and oceanographic observations of three submesoscale eddy formations in the coastal zone of the southeastern Baltic Sea. Each of the presented eddy processes is distinct in its morphometric characteristics, as well as in its location region and genesis. The paper examines and identifies features of the three-dimensional structure of currents arising within eddy formations and assesses the influence of eddy processes on the hydrological structure of waters. Small-scale individual cyclones forming in the coastal zone beyond Cape Gvardeysky represent purely surface circulation manifestations and do not entail any changes in the dynamic structure of waters, either spatially or in depth. Eddy dipoles arising in the area of Cape Taran, which have significantly larger spatial scales, are characterized by a more complex current structure. The study showed that the cyclonic portion of dipoles exhibits a significant increase in current velocities at the periphery and extends its influence to the underlying water layers. Differences in the structural features of eddy dipoles depending on their age are also demonstrated. Using two cases of eddy dipoles, detected in 2014 and 2021, it was shown that in both cases, upwelling of water was observed in areas of cyclonic vorticity, with the intensity of the process varying depending on the age of the structures and their spatial location.
