Southeast regional bathymetric contours consist of a vector coverage of bathymetric contours with increasing resolution in coastal areas. Contours were derived from a composite of several bathymetric datasets of varying regional coverage and resolution. Isobath intervals range from 2 meter in coastal areas to 200 meters in deep offshore areas.
This coverage was developed to compliment other regional spatial data utilized by ocean planners in addressing management issues. It is intended only to provide general information on regional scale ocean depth and bottom morphology.
Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI). The institute name has not been changed in historical data sets or references to work completed by the Florida Marine Research Institute. The institute name has been changed in references to ongoing research, new research, and contact information.

The attributes of vector contours were found to be consistent both with the source data, and two independently derived spatial data sets i.e. 1:17 k vector shorelines, and navigational charts. Due to the highly variable quality and resolution of the data from which these contours were derived, this general consistency should not serve as a basis for confidence in specific features, or lack of features, represented or implied by the data.
Portions of this coverage were derived from different source data and subjected to different processing methods, as a result, isobaths exhibit discontinuities in several regions. There is also logically inconsistent overlap or spacing between the 200 and 400-meter isobath in some areas.
Coastal contours of 2-meter depth intervals and variable vertical and horizontal resolution are available for the coastlines of North Carolina, South Carolina, Florida, and the majority of Georgia with the exception of a 30 km zone north of the Florida boarder. Depth contours at 10-meter intervals and variable vertical and horizontal resolution are available out to 100 m depth for the continental United States from 38N to 89W stretching from the Northern coastal boundary of Virginia to the eastern extent of Louisiana. Data within this zone is not included for areas outside the continental U.S. i.e. Mexico, Cuba, and the Bahamas. Depth contours at 200-meter intervals and variable vertical and horizontal resolution, are available for regions deeper than 200 meters for the entire extent of the coverage. Note: The spatial completeness of this coverage is a result of interpolation and does not reflect the completeness of the source data.
Processing methods utilized in the preparation of this coverage set the upper limits of horizontal accuracy at 90 meters for depths of 0 to 10 meters, 900 meters for depths of 10 to 200 meters, and 9 km for depths greater than 200 meters.
The vertical positional accuracy retained throughout processing does not exceed 1 meter
All contours with "source" attribute defined as "NGDC" were derived from this source data. The spatial extent of the portion of this coverage derived from this dataset is bounded to the North and South by the parallells 37N and 31N. The East-West extent ranges from the shoreline to the 200 meter isobath between 37N and 35N, and out to the 2200 meter iosbath between 35N and 37N.
Arcs derived from this data source are identified by the source attribute "geonex". The spatial extent ranges from the florida shoreline to a depth of 10 meters.
Arcs derived from this source data provide coverage of the Florida shelf and are identified by the source attribute "dbdb_v" and the res attribute "30sec". The spatial extent of the portion of the coverage derived from these data is bounded on the West by the meridian 85W and on the North by the parallel 31N. The data extends seaward from the 10 to the 200 meter isobath.
Arcs derived from this source data are identified by the source attribute "dbdb_v" and the res attribute "5min". Contours deeper than 200 meters for the entire coverage are derived from these data with the exception of the area described for in the source citation e_shelf. Contours up to the 10 meter depth in areas north of 37N and west of 85W were also derived from these data.
