Salt domes at the edge of the continental shelf in the Gulf of Mexico. Offshore salt domes were first discovered by the United States Coast and Geodetic Survey in the 1930's and properly identified as salt domes by Francis Shepard, the "father of submarine geology" who often worked with the C&GS.
Louisiana-Texas, Gulf of Mexico

Chart 5101A, first published in 1939, showing contours to be used for contour- following navigation. This was the first chart produced by the C&GS and among the first in the world to have adequate bathymetry for use by mariners as a navigational tool. The data was acquired in the 1930's as the result of radio- acoustic ranging surveys allowing precise positioning far from shore.

Operating the 50-inch camera designed by Captain Otis Reading, USC&GS. After the compilation drawing is completed, glass plates negatives were made by this precision camera, capable of photographing images up to 50 inches square. The error in reproducing images of this size was less than one thousandth of an inch.

Longitude and latitude lines are drawn on the Coast and Geodetic Survey projection ruling machine. This machine eliminated thousands of man-hours of drafting time that would have been required to produce the projections made for the thousands of maps produced for the Allied Armed Services during WWII. Barbara Clayton and Patricia Hayes are the operators of the machine.
Washington, D.C.
