The establishment of the U.S. Exclusive Economic Zone (EEZ) in 1983 "for the purpose of exploring, exploiting, conserving, and managing natural resources" presents the nation with an opportunity and a challenge to wisely use its diverse resources. Besides living resources such as fisheries, this vast region contains extensive and potentially valuable mineral and energy resources, and is used for various other purposesâ?"such as waste disposal, pipelines, cables, and military uses. This book assesses the state of knowledge of seafloor properties and processes as they relate to future utilization of the U.S. EEZ seabed.
