            The goals of this chapter include: 1) providing users with the ability to visualize the textural information in a geographic context (Polloni  and others, 1995),  2)  supplying maps in flexible scales for synthesis (Kenwood and others, 1996; Polloni  and  others, 1998 ), and 3) giving users the ability to identify and query geographic and attribute data (Polloni, 1998a, b). The primary effort is to deliver the textural data as geo-referenced points so that they can be used on basemaps for other digital data from along the U.S. east coast.  Project files are included that already have the inter-disciplinary data layers loaded as theme coverages  (Fig. 1).  The user can turn data layers on or off,  measure distances in user specified units,  and add, if available,  other  user specified themes as long as they are in the same coordinate system  (i.e. latitude and longitude in decimal degrees).    Coverages in state plane or other coordinate systems must be re-projected to be compatible with these data.

            One of the data layers provided here was originally produced for the Continental Margin Mapping Project (CONMAP; Klitgord and Hill, 1986; Escowitz, 1987) of the U.S. Geological Survey (USGS). As part of CONMAP, syntheses of surficial sediment studies on the U.S. Atlantic continental margins were compiled in a series of standardized maps and digital databases to facilitate the transfer and use of the extensive information acquired by the USGS (Poppe and others, 1989; Poppe and others, 1994).  The maps, which are intended to be reproduced at a scale of 1:1,000,000, are on an Albers Conic Equal Area Projection with standard parallels at 29.5oN and 45.5oN, and are compatible with the U.S. National Atlas and the USGS geologic and tectonic maps.  Although combined for this report, the Atlantic margin was divided into the following four regions for the CONMAP series: Georges Bank Basin and Gulf of Maine, Baltimore Canyon Trough, Carolina Trough, and Blake Plateau Basin.  The sediment map from northern-most region was previously released in digital form as part of a marine geographic information system (GIS) library for Massachusetts Bay (Butman and Lindsay, 1999).

            Each sediment map in the CONMAP series is a compilation of grain-size data produced in the sedimentation laboratory of the Woods Hole Field Center of the Coastal and Marine Geology Program of the USGS and from both published and unpublished studies.  These studies are listed in alphabetical order in the data bibliography (Appendix A).  Sediment was classified using the Wentworth (1929) grain-size scale and the Shepard (1954) scheme of sediment classification. Certain grain-size categories are combined because of the paucity of some sediment textures; blank parts of the maps indicate areas where data are insufficient to infer sediment type.  Bathymetry is used as a guide in placing some of the contacts between different sediment types.  However, because the true boundaries between sediment types are probably highly irregular or gradational, because the extreme textural variability that characterizes some areas does not appear at this scale, and because the accuracy of the navigational systems used during the earlier studies is limited, all contacts should be considered to be inferred.  In summary, the CONMAP series is old and does not accurately depict small-scale sediment distributions.  This data layer is supplied primarily as a gross overview and to show general textural trends. areacdsm.gif

             As part of the Continental Margin Program (Emery and Schlee, 1968; Hathaway, 1971), the U.S. east-coast offshore was divided into 64 distinct marine geographic areas. These areas, which are designated by codes and corresponding descriptions (Fig. 2; Appendix B), are also included as a data layer. They are provided to help users visualize the sample locations and sediment distributions in smaller-scale regional contexts.




            We have provided the GIS ArcExplorer version 1.1 software so that a user with a Windows 95/98 compatible operating system can down-load it to their own system and use it to display the coverages provided.   ArcExplorer can read ArcView shape files included on the CD-ROM and also, if connected to the WWW, can incorporate coverages which may be available on GIS web servers.   A manual for ArcExplorer version 1.1 is also provided in Adobe Acrobat (PDF) format.  The user must have the Adobe Acrobat software installed to read the ArcExplorer manual.  The user is encouraged to get the latest version of the ArcExplorer and Adobe Acrobat software directly from ESRI and Adobe, respectively, on the WWW. 


            Separate project files are included for both ArcExplorer 1.1 and ArcView 3.1.   If you have loaded ArcExplorer 1.1, you can use the project file GEOCST.AEP.   This mapping tool will display the data selected in a geographic coordinate system.  If you have ArcView version 3.1 or later on a Windows 95/98 system, you should be able to use the EASTCST.APR project file and have the coverages appear on your screen in an Lambert Equal-Area Azimuthal projection and GEOCST.APR to view them in an unprojected geographic display.  The images (GLORIA and Elevated Shaded Relief) are both projected only in Lambert Equal-Area Azimuthal and thus are only visible in that projection.  For UNIX systems we have provided the EASTCSTU.APR and GEOCSTU.APR project files.  All project files are available in the root directory of the CD-ROMFor best results, exit from your browser, activate the mapping tool and open the appropriate project file.

            Although the data assembled on this CD-ROM comes from a variety of sources,  we have translated the data layers to be compatible with the desktop mapping tools ArcExplorer and ArcView from ESRI.   The data layers provide texture data and interpretations for integration and viewing;  additional layers (e.g. coastline, bathymetry, state boundaries) have been included for regional reference purposes (Fig. 1).  All data has available metadata for source and quality definition.  All data with attributes can be queried to display as much as is available in the individual records.

            A set of project files for ArcExplorer and ArcView are included so that the user can use them directly.  The project files have links to the data layers provided on the CD-ROM and these links can be switched on and off.  ArcExplorer has been included on this CD-ROM for off-loading to a users computer system.  Instructions for set-up on the users computer system are included in the ArcExplorer user manual.  To install the ArcExplorer software, click on the highlighted "ArcExplorer version 1.1" software link.   Windows will inform the user that this may be downloaded or  run from its current location.  The application will install if the user selects the run from current location and follow the instructions for the complete install.  If you have a browser that only has an option to download (ie NETSCAPE), then the user must download the file (Aeclient.exe, 7Mbyte) and execute the file under their operating system. Aeclient will install ArcExplorer 1.1 and provide a shortcut for the user to restart the software.  Once ArcExplorer is loaded, the user may use the project file (geocst.aep) to add the primary set of data themes.  Other data themes that are in the same coordinate system may be added at this time.  If the user has ArcView, the project file (eastcst.apr) can be used. Both project files have been edited to act with relative file address pathing.
