For this broad view the resolution of the data was first reduced to 30 arcseconds about 928 meters north south but variable east west matching the best previously existing global digital topographic data set called gtopo30. The seabed depth varies from shallow light blue on the continental shelves to deep ocean basins dark blue. False most of the continental area of pangaea was located in the southern hemisphere. The topography of the northern atlantic ocean is shown in figure 18 2.
