Description:

Abstract:

In 1984 the USGS began a systematic program of reconnaissance-scale imaging of the poorly explored deepwater parts of the EEZ, using a long-range sidescan-sonar system known as GLORIA (Geologic LOng Range Inclined Asdic). The instrument was designed, built, and operated by the United Kingdom's Institute of Oceanographic Sciences (IOS). Imaging of the U.S. Atlantic East Coast was completed in 1987. These sidescan data data were subsequently processed, digitally mosaicked and published in atlas form in 1991.

The bathymetric contours which comprise this data layer were used in the atlas and were printed directly onto each GLORIA imagery sheet.

Purpose:

The EGLORIA_CNT data layer contains bathymetric contours for the US Atlantic East coast. The dataset was created for use with the EEZ GLORIA mapping program and was used as an overlay of the GLORIA sidescan sonar mosaics in the published Atlas. The data can be used with geographic information systems (GIS) software to display oceanographic information about the U.S. Atlantic East Coast.

Supplemental_Information:

The data are to be used for illustrations and illustrative maps on scientific topics. These data are NOT suitable to be used for any navigational or legal purpose. There is NO ASSURANCE of their accuracy, completeness, or precision. The contour line data are in most cases manually digitized from a variety of published or unpublished maps, and while we try to maintain attribution notes, such notes can be lost by incomplete access of a data set.

Contour intervals are every 250 m from -250 to -5000 m.
