Book excerpt: While the Arctic Ocean has long been covered with ice, recent changes in climate have caused the ice to melt, spurring both conservation challenges to the region's environment and biodiversity, as well as new opportunities for navigation and natural resource development. Changes in the Arctic Environment and the Law of the Sea offers policy and legal guidance in response to these new challenges. Synthesizing the presentations of leading experts at "Changes in the Arctic Environment and the Law of the Sea" meeting held in May, 2009 in Seward, Alaska, the topics explored in this volume include the political context and scientific background, marine transport, environment and biodiversity, in addition to offshore petroleum and the status of Spitsbergen. A list of selected Internet resources provides links for additional websites, as well as PowerPoint files from presentations given at the meeting. Changes in the Arctic Environment and the Law of the Sea is based on the 33rd Annual Conference of the Center for Oceans Law and Policy, a primary sponsor, along with the Law of the Sea Institute of Iceland as well as with the U.S. Arctic Commission, the University of Alaska (Fairbanks) and the Law of the Sea Institute, Law School (Boalt Hall), University of California, Berkeley.
