Isolines show the approximate age in million years of the ocean floor bedrock on each side of the mid atlantic ridge. The topography of the northern atlantic ocean is shown in figure 18 2. False most of the continental area of pangaea was located in the southern hemisphere. 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.
