PLATE 6 Integration of GLORIA data with bathymetric data has proven 

 extremely effective in visualizing seafloor geology. This photo shows a 

 perspective view of a portion of the Florida Escarpment with the small 

 ravines cut into it and the meandering channel running across the abys- 

 sal plain floor at the base of the escarpment. Photo courtesy of Dr. David

PLATE 7 Shaded relief image of Seabeam bathymetry along the Texas- 

 Louisiana continental slope. Data collected by the NOAA National Ocean 

 Survey. This image shows part of the Sigsbee Escarpment, several collapse 

 basins north of the escarpment, and one salt diaper south of the escarp- 

 ment. Area shown is approximately 50 by 60 nautical miles. Photo cour-
