We are poised to embark on a new era of discovery in the studyof geomorphology. The discipline has a long and illustrioushistory, but in recent years an entirely new way of studyinglandscapes and seascapes has been developed. It involves theuse of 3D seismic data. Just as CAT scans allow medical staffto view our anatomy in 3D, seismic data now allows Earth scientiststo do what the early geomorphologists could only dream of -view tens and hundreds of square kilometres of the Earth's subsurfacein 3D and therefore see for the first time how landscapes haveevolved through time. This volume demonstrates how earth scientistsare starting to use this relatively new tool to study the dynamicof a range of sedimentary environments.
