The present Ph.D. study titled “Study on the relation of radioactive pollution and satellite observations of marine parameters and comparative analysis on a Geographic Information System”, aims at the creation of an innovative tool dedicated to the remote control of the conservative pollutants in the marine environment, by integration of in situ measurements, satellite observations and GIS for routine and emergency radiological inventory at first, but also extrapolated to other diluted pollutants too. The case study which will be investigated during this project is in the Aegean Sea, Eastern Mediterranean. Therefore, a program has been developed to explore the relations of Sea Surface Temperature, Sea Surface Salinity, Ocean Colour (OC) parameters (Chlorophyll-A concentration, Particulate Inorganic Carbon concentration, Particulate Organic Carbon concentration, Instantaneous and Daily Photosynthetically Available Radiation) and Biogeochemical parameters (Nitrates concentration, Phosphates Concentration, pH) with 137Cs activity concentrations in the Aegean Sea and analyze them to a GIS platform, as a first step for the development of this tool. SMOS, MODIS, VIIRS and CMEMS time series data are acquired processed and correlated with real time measurements of 137Cs activity concentrations from the Aegean Sea aspiring to result to a conjoint modelscheme for remote survey recording and forecasting pollutant inventory. Furthermore, additional environmental and radiological parameters and models (e.g. ecological and biological half-lives, relative biological effectiveness) will be used to the inter-relations among the study variables and biota in a GIS platform for integration to the impact level. Therefore, the innovative tool will be used for the remote detecting of: a) the inventory of radioactive pollution for a cost efficient monitoring in the marine environment to assess the radiological status, b) the impact assessment of possible radiological events and incidents, c) the estimation of the effects on the ecological pyramid (food chain) of radioactive pollution for dose estimations to both humans and ecosystems on the basis of “the one health concept” (potential capacity) whereas could be used: for the application of scenarios for forecast under accidental releases and furthermore and to investigate the application for other conservative pollutants (e.g. potential capacity heavy/trace metals). Moreover, it may be a reliable tool for support to the decision makers for early application of countermeasures in case of radiological events.
