3-D view of Bear Seamount. The concave appearance of the top is an artifact caused by the surveying ship "hovering" over the top of the seamount.

Track of the Surveying Brig DOLPHIN from September 1851 to July 1852. This track chart contains depth information, currents, winds, and other observations. It could be fair to say that U.S. Navy deep sea oceanography began with this cruise ordered by Matthew Fontaine Maury with the DOLPHIN under the command of Lieutenant Samuel Phillips Lee, USN.

Station observations of the Surveying Brig DOLPHIN in the South Atlantic in what was called the "Volcanic Region".

Early bathymetric and geologic map of the English Channel area by Philippe Buache in 1752. Contours were used to express depth of the water before being used to express elevation.

Survey track of the Coast Survey Steamer HASSLER on the coast of California showing depth profiles of the continental slope. Survey was run in 1874 and meant "to determine the 500 fathom curve."

"Admiralty Chart of the North Atlantic Ocean showing bathymetrical colouring" by Sir John Murray and R. E. Peake. Incorporating soundings by S.S. Faraday and S.S. Minia 1903 and soundings at the Azores by the Prince of Monaco 1902.

Inset maps of Admiralty Chart of the North Atlantic Ocean showing soundings by S.S. Minia 1903 and S.S. Faraday 1903. These soundings were taken with a piano-wire sounding system and represented a number of days work for each ship to acquire soundings of this density in the mid-ocean.
