The 1st leg of the voyage was used for ship inspections off Labrador at 57.5°N (May 10-June 10); Stopover in Tromsø (June 10-12); the 2nd leg of the journey was in the Fram Strait.The sometimes very high ozone mixture ratios in the first part of the voyage are due to stratospheric intrusions, since according to the ship's weather station report there was a relatively stationary complex atmospheric low system off Newfoundland. This is favorable for the formation of tropopause folds. During the 2nd leg of the voyage, very low ozone mixture ratios were measured at times at 70°N, which were probably due to ozone depletion by bromine during sunny weather. ... : Positions might be approximate. ...
