Description: A sketch from a map of the 1888 United States Hydrologic office, showing the Atlantic Basin, outline of the continents, 500 fathom submerged shoreline, and 2,000 fathom submerged shoreline. Depths varying from 1,000 fathoms to 1,000 fathoms are shown by horizontal lines, from 1,000 to 500 fathoms by perpendicular lines, and the crossed lines show the shallowest spots in mid–ocean of 500 fathoms or less. The areas of greatest depth (over 3,500 fathoms) are marked with crosses.
