    How to view and interpret the Smart buoy oil data
    The results of the measuring station are viewable by clicking the on the map or the button below the map on the front page. The results are first presented in graphic format (the last 30 days) and below the graphs the results of the latest hours are presented in table format. You can download the measurement series to your own computer in excel-compatible format by pressing “Download to a file” button. All service events at the measuring station can be viewed by clicking “Browse the service history of the station”.

    The results based on fluorometers (oil hydrocarbon and CDOM (colored dissolved organic matter)) are given as non-calibrated raw data and presented as RFU (relative fluorescence unit). A possible oil contamination drifting to the buoy area would result in a significant increase in oil hydrocarbon concentration compared to turbidity and CDOM, which would remain at the basic level at the same time. If an increase is also observed in CDOM values, an increased oil hydrocarbon concentration may not be the result of an oil spill, but merely a result of natural organic compounds being transported from coastal areas, as these compounds are measured at the same wavelengths.
