It has been common practice in marine topography to represent depth by means of graded contour lines. To accentuate change in ocean shape as a function of depth, this report portrays the world's ocean basins in a series of regional single-depth charts at 500-fathom intervals from 500 to 3500 fathoms. Land masses at or above sea level are shown solid black. Ocean bottom above chart depth is shaded. Water deeper than chart depth is shown white. Three sets of charts are available. Set 1 comprises the series of regional single-depth charts, a locator, and a series of composite world charts, all 8 by 10 1/2 inches. Set 2 contains a locator and the regional maps in 17-by-22-inch size for use in plotting, plus the world charts in 22-by-34-inch size for wall mounting. The charts were prepared from U. S. Navy Hydrographic Office Chart H. O. Misc. 15,254, titled ''THE WORLD.'' Contains briefing charts only.
