Labeled atlantic ocean floor map.

Earth geology ocean floor image ocean floor wall map by geonova noaa ocean explorer education interactive 3 d seafloor map. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. 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 topography of the northern atlantic ocean is shown in figure 18 2.

41 100 000 sq mi 106 460 000 sq km. Ocean floor map labeled. Typically finely wrought ocean maps have been the result of extensive sonar. 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.

New lithosphere is created by volcanic activity along the crest of the ridge and the plates on either side of the ridge are moving away from one another. Published today this is the most detailed map of the ocean floor ever produced using satellite imagery to show ridges and trenches of the earth s underwater surface even for areas which have. In 1922 a historic moment in cartography and oceanography occurred. Accra dakar abidjan tangier.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Mid ocean ridges are divergent boundaries where convection currents in the mantle lift the ocean floor and produce a rift in the lithosphere that follows the crest of the ridge. Researchers have built a detailed map of the ocean floor s topography by using satellites to spot subtle watery lumps on the ocean s surface. This involved little guesswork because the idea of sonar is straight forward with pulses being sent from the vessel which bounce off the ocean floor then return to the vessel.

The uss stewart used a navy sonic depth finder to draw a continuous map across the bed of the atlantic. This is expensive and time consuming so sonar maps are mostly only made of places where ships spend the most time.
