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.
Atlantic ocean floor profile.
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 uss stewart used a navy sonic depth finder to draw a continuous map across the bed of the atlantic.
It covers approximately 20 percent of earth s surface and about 29 percent of its water surface area.
Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
The atlantic ocean is the second largest of the world s oceans with an area of about 106 460 000 km 2 41 100 000 sq mi.
This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries.
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.
The diagram above is a drawing of the bottom profile of the north atlantic ocean basin from the u s.
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 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 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.
1 continental margin 2 abyssal plain and 3 mid atlantic ridge.
Coast to europe showing the major features of the ocean floor.
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 spreading however is generally not uniform causing linear features perpendicular to the divergent boundaries.
Atlantic ocean floor topography lab.
A topographic profile of the pacific ocean floor between japan and british columbia is shown in figure 18 3.
In 1922 a historic moment in cartography and oceanography occurred.
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.
