Abstract The sulphur content in the precipitation collected on Ocean weather ships in the North Atlantic has been analysed. From these data and from the results of trajectory computations it is concluded that considerable amounts of anthropogenic sulphur are transported from North America towards Europe. the dry deposition of sulphur over the Atlantic must be small except close to the emitting sources. the amount of sulphur in precipitation from air coming from the high pressure area near the Azores is very small. It is concluded that the normal global value of natural sulphur in precipitation can hardly be larger than 0.1 mg 1 −1 .
