In 2007, the International Max Planck Research School for Maritime Affairs together with the International Tribunal for the Law of the Sea (ITLOS), both based in Hamburg, decided to establish an annual lecture series, the "Hamburg Lectures on Maritime Affairs" - giving distinguished scholars and practitioners the opportunity to present and discuss recent developments in this field. The present volume - the second in the series - collects eight of the lectures held in 2009 and 2010 by David Joseph Attard, Lucius Caflisch, Beate Czerwenka, Lars Gorton, Francesco Munari, Kyriaki Noussia, Peter Wetterstein and Wolfgang Wurmnest.
