In addition to the examination of dab (Limanda limanda), Baltic cod (Gadus morhua) and Baltic flounder (Platichthys flesus) for macroscopically visible external and internal diseases and parasites, extensive samples for the CHEMSEA project were taken for measurements on dumped chemical weapons and their biological effects. In particular, cod samples were taken for the CHEMSEA project in areas B09, B13 and B15. In addition, fish samples were frozen for the detection of contaminants (incl. radioactive substances) in the framework of national legislation (BLMP) and international monitoring programmes (HELCOM). Hydrographical measurements were carried out (water temperature, salinity, oxygen content, turbidity).
