In the region of the Baltic Sea, maritime security has risen in importance due to an increase in maritime traffic volume. This is of special concern to various neighboring regions which include the resund region with Copenhagen and Malm; the Polish region of Pomerania with Gdansk, Gdynia, and Sopot; as well as to the northwestern region of Russia. This matter is vitally important for Hamburg's port, the second largest in Europe. The River Elbe is one of the busiest waterways of the world which makes Hamburg's economy essentially dependent on the security of the waterways. The International Tribunal for the Law of the Sea (ITLOS) held a conference in Hamburg in 2007 bringing together judges, practitioners, experts, and students to discuss problems and solutions for maritime security. This book is a collection of the conference proceedings which are meant to foster cooperation and mutual understanding of the contemporary legal and security issues around the Baltic Sea.
