5. Annual Meeting, June 15-16 2015, Istanbul, Turkey Difficulties encountered: Data in many different formats (Excel files), takes time to restructure the data The chemistry data has not been available to others before, researchers concerned that data can be misused Radionuclides in biota: Data can be based on samples from more than one station – which position should be used? ODV format: Not possible to use platform code
