This thoroughly revised and updated third edition of the prestigious casebook provides an essential overview of landmark legal decisions and statutory provisions in U.S. marine and coastal law, with a particular emphasis on regulatory changes and legal conflicts involving climate change, coastal resilience/protection, and sea level rise. In addition to a thorough updating of the contents of the second edition (including editorial commentary on every case), this new revised edition features extensive new content, including two entirely new chapters and new "learning objectives" for each chapter. Produced by five experts in U.S. marine law, this third edition stands as an accessible and invaluable resource for both lay readers and legal professionals who are seeking greater understanding of the ever-evolving and frequently contentious laws and regulations governing U.S. and international fisheries, maritime shipping and transport, offshore oil and mineral resources, climate change mitigation strategies, coastal protection, marine pollution, and port and harbor operations.
