ArcGIS Project Readme

The map documents and shapefiles used to create the vibracore location maps provided on this disc can be found in the Arc_CI.zip file located in the ARC subfolder of the Software folder located at the top level of the disc. The map documents were created with ESRI ArcGIS 9.3 software. Shapefiles may also be viewed with other versions of ArcGIS, ArcView, or public domain software ArcExplorer ().

The study area map document (.mxd) utilizes a naming scheme incorporating the study area (Chan), for Chandeleur Island and year of last collection (07), would be Chan_07_Basemap.mxd. These maps display 07SCC and CI87 vibracore location data points. Shapefiles of the vibracore location datasets use a similar naming scheme to that of the maps. They are named using a shortened name of the cruise (07SCC or CI87). For example, core locations for 07SCC04, 07SCC05 would be named 07SCC.shp. The interactive maps (on the HTML pages) show the 07SCC surveys (red dots) and the CI87 surveys (blue dots). Only the zoomed in area map (HTML) vibracores are labeled. Clicking on the core data point or the core ID will access the Core Data Table, which contains all sediment core data and displays the specific core information.

The list below describes the shapefiles provided with the ArcGIS project. Metadata are available as HTML documents (viewable with any Web browser) and XML documents (used by ArcCatalog).

07SCC.shp:

Comprehensive point layer file for vibracores collected during cruises 07SCC04 and 07SCC05

CI87.shp:

Comprehensive point layer file of vibracores collected during research cruise 87039

Gulf of Mexico Coastline:

Polygon layer of the Gulf of Mexico shoreline is a vector coastline map of the Northern Gulf of Mexico states from Texas to Florida USA. This shapefile is for a visual coastline reference layer only, NOT to be used for navigation.

Raw_Data Folder:

Contains the original .csv files for the 07SCC_ and CI87_ (i.e. 07SCC_XY.csv) latitude and longitude locations for each core.
