The Living Planet Symposium (LPS2019) of ESA took place on the 13-17 of May 2019 in Milan, Italy. GET in cooperation with the Environmental Radioactivity Laboratory of NCSR“D” and Ph.D. candidate Georgia Mavrokefalou, under the Industrial Scholarship Program of NCSR“D” and Stavros Niarchos Foundation (SNF), successfully presented a poster presentation titled “Use of Copernicus Marine Envrionment Monitoring Services (CMEMS) for the Remote Tracking of Marine Radioactive Pollution”.  This work presents the estimated activity concentrations of the radionuclide Cesium-137 (137Cs) using CMEMS data in the marine regions of North Aegean, Souda Bay and Corinth-Patras Gulf. The estimations were then compared to actual 137Cs activity concentration measurements taken from seawater samplings and analyses. From the comparison of the estimated and the actual measurements it appeared that the estimated measurements are quite close to the actual ones (r2>0.80). Moreover, from the seawater samplings and measurements carried out during this work, it seems that in recent years the 137Cs activity concentration values remain quite stable; South Aegean Sea and Corinth-Patras Gulf exhibit values lower than 5 Bq/m3 and North Aegean Sea exhibit values lower than 8 Bq/m3.
