Atlantic Ocean Floor Topography

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.

Atlantic ocean floor topography.

Ocean topography off the southeast portion of the united states. A topographic representation of the sea floor around the charleston bump. Scientists used multibeam bathymetric data to create a 3 d view of a portion of the charleston bump. Covering approximately 20 percent of globe s surface the atlantic is second only to the pacific ocean in size.

The topography of the northern atlantic ocean is shown in figure 18 2. Because the continents bordering its waters in the north are offset to the west of those in the south the atlantic appears as an elongated northsouth s shaped channel. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. It covers approximately 20 percent of earth s surface and about 29 percent of its water surface area.

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. It separates the old world from the new world the atlantic ocean occupies an elongated s shaped basin extending longitudinally between europe and africa to the east. This product is intended to aid fishermen and those needing seafloor features and potential fishing grounds. Sea surface temperature readings.

The atlantic ocean is the second largest of the earth s oceans. 18 1 the topography of the sea floor we examined the topography of the sea floor from the perspective of plate tectonics in chapter 10 but here we are going to take another look at the important features from an oceanographic perspective. The outstanding feature of the atlantic floor is the mid atlantic ridge an immense median mountain range extending throughout the length of the atlantic claiming the centre third of the ocean bed and reaching roughly 1 000 miles 1 600 km in breadth. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
