Wet chemical surface ozone measurements during YMER cruise Y80 in June-August 1980

To mark the centenary of Swedish polar explorer Nordenskjöld's research trip, Sweden hosted a new research trip to the polar region between Franz Josef Land, Svalbard and Greenland. The icebreaker Ymer, which otherwise operates in the Baltic Sea, was used for this purpose. Several containers were set up on the prow in front of the bridge. The ozone device was installed in an air chemistry laboratory container on the port side, from where the intake line was routed to the railing mounted above. The voyage was mostly in the pack-ice belt and the crew was instructed to keep the ship bow-to-wind whenever possible so that air-chemical measurements with long sampling times remained undisturbed. The device was stable. On the return trip to Stockholm, the wind was mostly unfavorable, so that south of 70°N hardly any usable data could be obtained.
