During the 1965 Atlantic Expedition of the "Meteor“ concentrations of various atmospheric trace gases were measured. The following gases were considered: carbon dioxide (CO2), sulfur dioxide (SO2), nitrogene dioxide (NO2), and nitric oxide (NO). The air whereof these components were measured was sucked in from a height of 14 m above the surface of the sea. The results allow conclusions upon the long term global increase of the atmospheric CO2 content, the meridional distribution of the CO2 on the Atlantic Ocean, and the dependance of its concentration upon the time of the day and the thermal structure of the atmosphere. Attempts at determining concentrations of sulfur dioxide and nitric oxide of non-continental origin failed at large. Concentrations of NO2, however, could succesfully be measured.
