Title page to "Die Tiefenverhaltnisse des Offenen Atlantischen Ozeans" 1935. By Theodor Stocks and George Wust. This work was an analysis of the bathymetry of the METEOR cruise showing the most detailed morphological information of the seafloor ever attained up to that time. It clearly showed the nature of the Mid- Atlantic Ridge and led eventually to the discovery of the median valley.

C&GS Chart 5101A, 1939, a prototype chart incorporating bathymetry acquired with RAR navigation by the C&GS out to oceanic depths. This chart was meant for navigation by following bottom contours. No other chart like this was ever produced as WWII intervened and the use of electronic navigation systems became widespread. The C&GS surveyed the continental margin of the U.S. by 1939.

The famous A.C. Veatch and Paul Smith map of the Mid-Atlantic continental slope which attracted great attention from the scientific world as it showed the results of precision radio acoustic ranging navigation and acoustic sounding. With the exception of Hudson Canyon, none of the other canyons were known at the time of publication of this map.

Harold Murray of the C&GS published this pioneering study of undersea mountains 1941. Many of the seamounts depicted on this chart were flat-topped seamounts later termed guyots by Harry Hess of Princeton.

The discovery survey of Astoria Canyon off the Oregon coast. The lines of dots are lines of soundings navigated by means of radio-acoustic ranging, the first precision navigation system to eliminate the need for visual signals. This system was developed by the C&GS in the 1920's and used until WWII. Many discoveries were made because of it.
