| Purpose | This cruise was the first leg of the joint USGS/IOS GLORIA Survey of the East Coast Atlantic Margin Exclusive Economic Zone (EEZ). The cruise covered a portion of the EEZ that included the northern Blake Plateau and the continental slope and rise off Georgia, South Carolina, and North Carolina, from the 400 isobath to the 200 mile EEZ boundary. The British Institute of Oceanographic Sciences' (IOS) long-range sidescan sonar system (GLORIA) was contracted by the USGS to produce a reconnaissance-type map of the sea floor within the U.S. EEZ of the conterminous United States, Hawaii and Puerto Rico. The survey is being done to provide a basic understanding of the EEZ, including resource potential and geologic hazards. | ||||||||
