Directory Structure:

Top level directory:

index.htm - This file is intended to be the starting point for the DVD-ROM access.

allpulley.apr - ArcView project file created with ArcView 3.3 on a Windows XP computer. This project file uses TIFF images with associated world files rather than ESRI formatted grids removing dependency on extensions that do not come standard with ArcView 3.3.

allpulley_sa.apr - ArcView project file created with ArcView 3.3 on a Windows XP computer. This ArcView project contains grids and therefore requires the ArcView extension Spatial Analyst.


Directory data - What follows is a brief description of the data contained in the underlying directories which are utilized in the GIS. For a more complete description of the data, refer to the data catalog page and the metadata associated with each data file. This directory contains the following subdirectories:

  • basemap - this folder includes low-resolution color shaded-relief georeferenced TIFF images of the region, a portion of the U.S. state boundaries for location reference, and shapefiles describing the bounds of the study area.
  • bathymetry - contains high-resolution swath bathymetry grids and georeferenced TIFF images of the study area, as well as hillshade representation of the bathymetry. These data were collected in 1999, 2000, 2001 and 2003.
  • interpretation - shapefile of the interpretation of the seafloor within the study area
  • rov_sub - contains three subdirectories with shapefiles of navigation pertaining to submersible and ROV operations within the study area from the years 1999, 2000 and 2001. These subdirectories are rov99, rov2001, and sse. SSE refers to the Sustainable Seas Expedition submarine navigation.
  • seaboss - contains shapefiles pertaining to the navigation associated with the Seabed Observation and Sampling System (SeaBOSS) which includes points for individual photos, as well as tracklines during which video imagery was acquired in 2003. The subdirectory jpegs in turn contains numerous subdirectories based on CD number (i.e.cd2444) which contain JPEG images of digitized bottom photographs acquired by SeaBOSS.
  • seismic - contains shapefiles of the seismic navigation from 1996 and 2001, both tracklines and shotpoint navigation. The subdirectory images contains JPEG images of the seismic-reflection profiles corresponding to the navigation.
  • sidescan - contains sidescan-sonar mosaics of the seafloor in the study area collected in 2001. Subdirectories indicate the projection of the imagery, either geographic or UTM (zone 17, NAD83). These images are available in TIFF format.
  • visualization - contains MPEG animations and Fledermaus scene files which show the relationship between the high-resolution bathymetry and SeaBOSS bottom photographs.
