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.
Atlantic ocean floor profile.
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.
In 1922 a historic moment in cartography and oceanography occurred.
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 diagram above is a drawing of the bottom profile of the north atlantic ocean basin from the u s.
The data table shows a record of the depth of the atlantic ocean measured by a research vessel travelling on course due east along 39on latitude.

A topographic profile of the pacific ocean floor between japan and british columbia is shown in figure 18 3.
Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge.
The uss stewart used a navy sonic depth finder to draw a continuous map across the bed of the atlantic.
Be careful when interpreting this diagram and others like it because in order to show the various features clearly the vertical axis is exaggerated in this case by about 200 times.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
1 continental margin 2 abyssal plain and 3 mid atlantic ridge.
Atlantic ocean floor topography lab.
Coast to europe showing the major features of the ocean floor.
It covers approximately 20 percent of earth s surface and about 29 percent of its water surface area.
This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries.
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.
The second largest ocean on earth the atlantic drives our weather patterns including hurricanes and is home to many species from sea turtles to dolphins.
The sea floor can be subdivided into three major features.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
