Wet chemical surface ozone measurements during POLARSTERN cruise ARK-VII/3 (PS17) in 1990@en

The north-south profiles show the decrease in ozone mixing ratios towards the north in high geographical latitudes, which was also found on other trips. The mean latitudinal distribution of the ozone mixing ratio appears not to run through the cluster of datapoints, because the ship stayed at several stations for longer periods and frequently encountered higher ozone mixing ratios there. During the voyage, oceanographic, marine biological and geoscientific questions were investigated.
