Seabed Mechanics : Edited Proceedings of a Symposium, sponsored jointly by the International Union of Theoretical and Applied Mechanics (IUTAM) and the International Union of Geodesy and Geophysics (IUGG), and held at the University of Newcastle upon Tyne

Symposia do not just happen, and those which venture on the Bureau of IUT AM. I was on the train like a into new territory happen even less frequently.
