Data Integration and Visualization, Hueneme Canyon and Vicinity, CA

Collage of imagery of the seafloor, one is a photo, the others are generated from depth data with a computer.

Detailed Description

 The map view in the center of the sheet is similar to the colored shaded-relief bathymetry map of Hueneme Canyon and vicinity (sheet 1 of this report). Numbered arrows show viewing directions of the perspective views on this sheet (figs. 1, 2, 3, 5, 6); the numbers indicate the figure number of the perspective view. The perspective views and bathymetric profiles in figures 1, 2, and 5 show the colored shaded-relief bathymetry of Hueneme Canyon, as viewed from the south, southeast, and southwest, respectively. These views show a few examples of the complexity of the canyon terrain and try to match the scale of the terrain with more commonly known structures.

Draping the acoustic-backscatter imagery (see sheet 3 of this report) over the bathymetry data (fig. 3) highlights the relations between the backscatter intensity and the seafloor morphology, as well as any anthropogenic influences on the seafloor. Video-mosaic images created from seafloor digital video (fig. 4) display the geologic (rock, sand, mud) and biologic complexity of the seafloor. Whereas photographs capture high-quality snapshots of a small area of the seafloor, video mosaics can capture larger areas and, thus, can show transitional zones between different seafloor environments.

Block diagrams (fig. 6), which combine the bathymetry with seismic-reflection-profile data, help reveal the stratigraphic and structural relations between the surface and subsurface.
