Map of atlantic seafloor.

These systems provided the databases to construct the first real maps of important features such as the deep sea trenches and mid ocean ridges. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Each consist of three sheets a base bathymetric map. A computer enhanced multibeam bathymetry map of the northwestern and northern gulf of mexico continental shelf and slope.

The map has more than twice the resolution of previous seafloor maps and shows a plethora of never before seen features. Unseen details of seafloor exposed in these maps of the atlantic ocean floor the detail of such submarine terrain as continental slopes abyssal plains and the mighty mid atlantic ridge is stunning. Map of the northern gulf of mexico showing the nearly 4 000 active oil and gas platforms. A marine gravity map of the north atlantic ocean red dots show locations of earthquakes with magnitude 5 5 and they highlight the present day location of the seafloor spreading ridges and.

The colors on this reflectivity map describe the hardness of the seafloor surface. In 1957 the publication of heezen and tharp s physiographic map of the north atlantic was the first map of the seafloor that allowed the general public to begin to visualize the ocean floor. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. The results that let this new marvelously detailed map of the seafloor from nasa s earth observatory be made were actually first published last year as part of a paper in science from.

Topographic maps of the sea floor produced at a 1 100 000 scale that contain loran c rates bottom sediment types and known bottom obstructions. This map shows the alvin dive track along the seafloor.
