Gloria mosaic of the deep sea floor off the Atlantic coast of the United States

This mosaic is a GLORIA (Geological LOng Range Inclined Asdic) view of the deep sea floor off the East Coast of the United States. It covers a surveyed region (fig. 1) of 195,000 square miles, an area nearly as large as Texas. The survey is part of a program to map the entire Exclusive Economic Zone (EEZ) of the United States and its island territories (also including Puerto Rico and the Northern Mariana Islands) carried out by the U.S. Geological Survey in cooperation with the British Institute of Oceanographic Sciences (IOS). A detailed atlas of the East Coast data has been published (EEZ-SCAN 87 Scientific Staff, 1991), and, along with this report, provides an overall view of the morphology and texture of the sea floor in the EEZ beyond the Continental Shelf.
