Abstract : The atlas contains 41 bathymetric charts covering the NOrtheastern Pacific Ocean between 4 degrees S and 60 degrees N latitude and from 140 degrees W longitude eastward to the American continental mainland. Sea floor relief is shown by means of 200-fathom contours based on a mean sound velocity of 4800 feet/second. Where sufficient data permits, the 100-fathom and 20-fathom contours are shown. Principal sounding lines used in compilation and analysis of the sea floor relief are indicated by a subdued grey overprint on each chart. The scale of the charts is approximately 1:4,500,000.
