Authors’ acknowledgement The authors wish to express their sincere gratitude to all those who supported us in the development of this book. A special thank you is dedicated to the persons who welcomed us at their workplaces and shared their knowledge and experiences about the Sound with us. Your contributions have been decisive and invaluable to this book. We are especially grateful to the photographer and pilot who carried out the aerial photography. Your effort has helped us visualize the Sound and show differences over time that otherwise wouldn’t have been possible. We are particularly indebted to all those who freely agreed to share images, drawings, maps and data with us. These have enriched the book by illustrating complex situations in an eloquent and graphically attractive way. We also wish to acknowledge the remarkable work of language editing and graphical layout that helped us translate our ideas into a book aimed for a large audience. Finally – and most importantly – we wish to thank our supervisor, Professor Olof Lindén, at the World Maritime University who never says no to new ideas and who first came up with the idea to write this book.

variety of goods and services. Settlements have been established along all coasts in the vicinity of fishing grounds and at maritime commerce points. The unprecedented growth in human population and the expansion in the global economy and trade of the last century have been accompanied by an ever increasing use and exploitation of the ocean. Technological advances, increasing levels of material wealth and growing concerns about the use of land-based resources have led to new claims for ocean space and resources. As a consequence, traditional maritime activities such as shipping, fishing and, in some parts of the world, aquaculture have to compete for limited space and resources with expanding offshore oil and gas exploitation, increasingly diverse maritime tourism activities, as well as emerging offshore renewable energy production and mineral resource exploration. The Sound1 constitutes no exception to this global trend. Historically a cornerstone in the political and economic
