Summary. During the EUGENO‐S field campaign in 1984 a large number of airgun shots were fired at sea in the Skagerrak and Kattegat and in Lake Vänern in southwestern Sweden. The signals were recorded on land by analogue “MARS” and digital “SN‐PCM‐80” three channel stations, by a digital 48 channel “SERCEL SN348” reflection instrument, and by “Geostore” stations. The airguns were shot about every 300 m along profiles up to 100 km in length. Clear reflected and refracted arrivals were observed from 5 km to 250 km shot‐receiver offset. The field and data processing techniques used are briefly described, and two examples of data are discussed.
