Education: attended the University of Cape Town
He was a geologist from South Africa. One of Alfred Wegner's early supporters of continental drift in the late 1900's.
Alfred WegenerBorn: November 1, 1880, Berlin, Germany
Died: November 2, 1930, Clarinetania, Greenland
Education: Kollnische Gymnasium in Berlin
Contributions: a German geophysicist and meteorologist, he was known for his acheivements in meteorology and as a polar researcher. He is now known for his continental drift theory which he backed with his discovery of palaeomagnetism.
Arthur HolmesBorn January 14, 1890, Gateshead, England
Died september 20, 1965, London, England
Education: Imperial colledge of London and the Royal Colledge of Science
Contributions: was the first scientist to grasp the implications of mantle convectionand he pioneered the use of radioactive dating of minerals
Hugo BenioffBorn: September 14, 1899
Education: Pomona Colledge ad California Institute of Technology
Contributions: Hugo Benioff was an American seismologist and he charted the location of deep earthquakes in the Pacific Ocean. He also built the first vertical siesmometer.
Kiyoo WadatiBorn: September 8, 1902
Education: University of Tokyo
Contributions: Kiyoo Wadati was a seismologist who researched on earthquakes. e discovered what is currently called the Wadati-benioff Zone, an area of deep and intermediate earthquakes along oceanic trenches. This became the base for the Plate Tectonics theory.
Harry HessBorn: May 24, 1906, New York City, USA
Died: August 25, 1969
Education: Yale and Princeton University
Contributions: a geologist and naval officer in WWII, Harry Hess was one of the founders of the theory of Plate Tectonics by discovering Sea-floor Spreading.
Sir Edward (Teddy) BullardBorn: September 21, 1907
Died: April 3, 1907
Education: University of Umbridge
Contributions: was a geologist who pioneered the use of siesmology to study the ocean floor and measured geothermal heat flow through oceanic crust.
Robert DietzBorn: September 14, 1914
Died: May 19, 1995
Contributions: As an American oceanographer, goephysicist, and a marine geologist, Robert Dietz worked alonside Harry Hess to discover Sea-floor Spreading. He made the point of saying that something like a coveyer belt must be carrying volcanic mountians (like the ones on Midway Island, Hawaii) northward.
Frederick Vine and Drummond MatthewsBorn: M: 1931 V:1939
Died: M: 1997 V:still alive
Contributions: discovered there was a pattern of magnetic strips across the ocean floor. Proving to be the first test of Sea-floor Spreading.
Glomar ChallengerContributions: In 1968 the Glomar challenger emberked on an expedition to called the Deep Sea Drilling Program, crossing back and forth over the mid atlantic ridge. It also drilled core samples a fixed locations on its 15 year-long journey.
