Abstract : The study utilizes what is already known about the distribution of North Atlantic Physiographic provinces in the preparation of a series of charts which schematically illustrate selected functions of relative relief, slope, and topographic texture. The data employed in compiling these charts was obtained by digitizing high resolution fathograms and, measuring relief, slope, and texture through the use of digital computers. Methods of data reduction and chart preparation are described in section II of this report. Statistical indices from slope data have been computed which characterize each physiographic province in the North Atlantic. From the charts and statistical data, it has been possible to briefly and quantitatively describe North Atlantic topography and to call attention to a number of interesting relationships and characteristics observed in the data which have a bearing on the geologic history and geomorphology of the Atlantic.
