Presents together for the first time the deep seismic reflection data collected around the British Isles by the BIRPS Group (BIRPS - British Institutions Reflection Profiling Syndicate). The boxed set of 100 seismic profiles provides a detailed image of the deep structure of the continental shelf of northwest Europe, crossing all of the major geological features off the shores of the British Isles. The BIRPS data provides some of the clearest seismic images of the deep continental crust and mantle available worldwide. Each profile is separately displayed at a scale of 1: 200,000, so that the majority are a handy A4 height that allows easy interpretation. The accompanying book provides of summary of the data acquisition and processing parameters and a brief guide to interpretation of seismic data.
