The Presidential proclamation on March 10, 1983, of a 200-nautical-mile-wide Exclusive Economic Zone (EEZ) focuses attention on the mineral resources of a vast submarine area. The hard-mineral resources in the EEZ include shallow-water placer deposits, polymetallic sulfide deposits, and cobalt-enriched manganese crusts in deeper water. The petroleum resource potential of basins within the EEZ is of importance especially in the deep water of the continental slope and rise. In order to formulate a national program to assess the resources in the EEZ, a symposium on 'A National Program for the Assessment and Development of the Mineral Resources of the United States Exclusive Economic Zone', was held at the National...

GLORIA long-range side-scan sonar imagery and 3.5-kHz seismic-reflection profiles depict a series of nine elongate deposits with generally high-backscatter surfaces covering most of the latest fanlobe sequence of the Mississippi Fan in the eastern Gulf of Mexico. The youngest deposit is a “slump” that covers a 250 by 100 km area of the middle and upper fan. The remaining mapped deposits, termed depositional lobes, are long (as much as 200 km) and relatively thin (less than 35 m thick) bodies. Small channels and lineations on the surface of many of these depositional lobes radiate from a single, larger main channel that is the conduit through which sediment has been supplied to these surficial deposits on the fan....

By proclamation of the President on March 10, 1983, the United States claimed sovereign rights and jurisdiction within an Exclusive Economic Zone (EEZ). The United States is responsible for wisely developing and managing the EEZ and its marine resources and for protecting its environment. The U.S. Exclusive Economic Zone is a region that extends seaward 200 nautical miles from the coast and brings within the national domain over 3 million square nautical miles of submarine lands. The EEZ contains vital natural resources, both living and nonliving, of the seabed, subsoil, and overlying water. Because most of the EEZ has not been explored, its resources and their potential remain undefined
