Samples taken around the wreck of the Franken in Gdansk

In the framework of the PHC-Polonium between MIO and IOPAN (The Institute of Oceanology of the Polish Academy of Sciences), the first sampling mission around the wreck of the Franken, a German supply ship sunk in 1945, took place from November 3 to 6. On board the Oceania, the IOPAN team and the MIO team, Stéphane Mounier and Benjamin Oursel (CEM). The program included profiles with the mini-fluo, prepared by Najib Bhairy (MIO-SAM) and Marc Tedetti (MIO-CEM), and water sampling to correlate the fluorescence signal and PAH content. Indeed, the wreck is likely to diffuse these contaminants in the bay of Gdansk and a direct measurement would be a plus for the monitoring of this spot. Due to the confinement, the measurements of PAH by GC-MS could not be done, but this is only a temporary solution
