The South Irish Seismic Experiment (SISSE) was completed from 27th to 31st August 1977. The experiment was originally planned as two crossing marine shot lines with onshore and offshore recordings at the ends of both lines. Due to bad weather only one of the shot lines with 37 shots was completed. This archive contains the digital data for the 8 MARS recording stations and paper plots of record sections for 3 of the 6 Geostore recording stations.
