Outer Continental Slope
(T. L. Holcombe, W. J. Renteria, and W. R. Bryant)
This 36″x48″ map covers the entire northwestern Gulf of Mexico, stretching across the Continental Shelf, Continental Slope, Mississippi Deep-sea Fan, and Ocean Basin. The contour interval is 2 meters on the Continental Shelf, 10 meters across the Shelf-Slope Break, and 40 meters across the Continental Slope and Ocean Basin. Sources are the entire array of NOAA hydrographic surveys and multibeam surveys, recent multibeam surveys of banks and other features of limited areal extent, and additional trackline data from random sources. Most of the underlying data are available from the NOAA Centers for Environmental Information (NCEI).
Maps of Outer Shelf Banks
(T. L. Holcombe, W. R. Bryant, and S. W. Bednarz)
This 37″ x 75″ map integrates the bathymetry of the Continental Shelf of the northwestern Gulf of Mexico, seamlessly with topographical maps of the coast, from Brownsville at the southern tip of Texas to the mouth of the Mississippi River in eastern Louisiana. Sources of bathymetry are some 3.5 million soundings from 291 historic NOAA hydrographic surveys conducted between 1930 and 2003. The underlying bathymetric sounding data are archived and made available by the NOAA National Centers for Environmental Information (NCEI).
Maps of Bathymetry and Land Topography, Texas-Louisiana Coastal Region
(T.L. Holcombe, C.A. Arias, and W.R. Bryant)
This 37″ x 75″ map contains bathymetry of 26 separate outer-shelf banks, 25 at a 1-meter contour interval and one at a 1/2-meter contour interval. All are indexed to a large bathymetric map of the Continental Shelf. Sources of bathymetry are multibeam surveys conducted by USGS, NOAA and HRI in 1998-2006. Individual maps of the banks are available at the link to the left.

Maps of South Texas Banks
(T.L. Holcombe, N.C. Slowey, and L.H. Holcombe; and J.W. Tunnell, Jr., H.L. Nash, and T.C. Shirley)
This 37″ X 35″ map contains bathymetry of 15 banks on the South Texas Continental Shelf, all having a contour interval of one meter. All are indexed to a large bathymetric map of the South Texas Continental Shelf. Bathymetric data were collected in 2012 by the Schmidt Oceanographic Institute, Palo Alto, CA, and made available by the Harte Research Institute for Gulf of Mexico Studies, Texas A&M University-Corpus Christi.
