Abstract

In 1984, the U.S. Geological Survey (USGS) began a program to map deep water portions of the Exclusive Economic Zone (EEZ) by selecting the long-range side scan sonar system GLORIA (Geological Long-Range Inclined ASDIC), owned and operated by the United Kingdom's Institute of Oceanographic Sciences (IOS), now the Southampton Oceanography Centre, Challenger Division.

The USGS selected side-scan sonar as the mapping tool because it could be used to obtain information on geologic processes. The intensity of the back-scattered sound from the seafloor is a function of the gradient or slope of the seafloor, of the surface roughness, and of the sediment characteristics such as texture. The darkness or brightness of a feature or an area on the sonographs and completed mosaics is therefore a function of how much sound is reflected from the seafloor. The recorded digital data are processed and used to construct digital maps of the seafloor.

Purpose:

To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act.
