Dr. Olga Sykioti Olga Sykioti is Associate Researcher at the Institute for Astronomy, Astrophysics, Space Applications and Remote Sensing of the National Observatory of Athens (IAASARS/NOA). She has a BSc in Geology, two MScs one in Remote Sensing and one in Hydrology, Geostatistics and Geochemistry and a PhD in Geosciences and Remote Sensing from Pierre & Marie Curie University (Paris, France). Her research interests focus in hyperspectral and microwave remote sensing in geosciences with emphasis in applications in the land and marine environment.
A program concept has been developed to utilize sea surface salinity (SSS), sea surface temperature (SST) and ocean color parameters for the comparison to the inventory of artificial radionuclides, which are conservative and part of the sea salinity. As a pilot study, time-series of SMOS and MODIS satellite measurements of ocean parameters are retrieved along with salinity profile measurements in order to investigate potential correlations to activity concentrations of 137Cs in the Aegean Sea (Greece). Other spectral indicators from satellite measurements of salinity changes are also investigated. The challenge of the study is the establishment of potential relations between satellite measurements of the marine environment and field radiological measurements resulting to a remote control tool for the radiological impact assessment under routine and event-case conditions. The presented results are a part of this effort.
