Book excerpt: One of the most creative innovations of the international diplomatic community in the 20th century was its invention of the international regime, a wrote Douglas M. Johnston in his last major work published posthumously (The Historical Foundations of World Order: The Tower and the Arena, Nijhoff, 2008). While regimes often provide order and certainty and a consequent reduction in disputes and misunderstandings, regimes are driven by specific concerns. With diverse disciplinary backgrounds and perspectives, the distinguished contributors to this tribute follow a long tradition of scholarly inquiry into the governance, creation, operation, viability and maintenance of international regimes. Their contributions on ocean and environmental regimes as diverse as fisheries, ocean dumping, maritime security, seafarersa (TM) rights, or enhancement of marine environmental protection attest to the depth to which modern international law and the underlying international relations have been transformed into an international law of structured cooperation. This book includes biographical and bibliographic notes on Douglas M. Johnston
