It allowed scientist to map the mid-ocean ridges. In the s scientists used magnetometers to detect magnetic variations on the ocean floor. Age acting rocks helped prove that mid-ocean ridges create new sea floor. They led to the discovery that magnetic strips on the sides of ridges on the ocean floor were the result of sea-floor spreading. This finding was very important to plate tectonics. He studied mid-ocean ridges. He suggested that a process he called sea-floor spreading continually adds new material to the ocean floor.
In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors carry the continents along with them. Du Troit was a South African geologist. He theorized that there were two great landmasses-Laurasia and Gondwana. Wadati was a Japanese seismologist. He wrote several papers. One of his papers proved the evidence of deep earthquakes. He also published the first accurate description of the inclined zone of deep earthquakes.
The Glomar Challenger was the first research ship that drilled samples of rock in the deep ocean floor. This drilling samples were evidence of sea-floor spreading. Plate Tectonics Theories and Scientists.

Equally famous is the Benioff strain instrument, which records the stretching of the Earth's surface. One of his most recent accomplishments was a refined version of the old Benioff seismometer which has given seismologists more knowledge about the cause of very deep earthquakes.
Benioff noticed that earthquake sources get deeper under the overriding tectonic plate proceeding away from the trench at a subduction zone. He realized that this inclined array of earthquake sources indicate the position of the portion of the plate that has already been subducted. Thus, that pattern of earthquakes is known as a Wadati—Benioff zone. From the early s, Benioff also worked on creating electric musical instruments; in particular a piano, violin and cello.
He continued developing these instruments for the rest of his life, working for over two decades with pianist Rosalyn Tureck and also, towards the end of his life with the Baldwin Piano Company.
