  • John Milne

     John Milne
    Born: December 30, 1850, Liverpool
    Died: July 31,1913, Shide, Isle of Wight
    Education: King's Colledge School
    Contributions: A British geologist and mining engineer who invented the first horozontal seismograph.
  • Alexander Du Toit

    Alexander Du Toit
    Born: March 14, 1878, in Rodenbosch, South Africa
    Died: February 25, 1948, in Cape Town, South Africa
    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 Wegener

    Alfred Wegener
    Born: 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 Holmes

    Arthur Holmes
    Born 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 Benioff

    Born: September 14, 1899
    Died: 1968
    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 Wadati

    Kiyoo Wadati
    Born: 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 Hess

    Harry Hess
    Born: 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) Bullard

    Sir Edward (Teddy) Bullard
    Born: 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 Dietz

    Born: 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 Matthews

    Frederick  Vine and Drummond Matthews
    Born: 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 Challenger

    Glomar Challenger
    Contributions: 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.

    The Atlantis ship
    Built: 1997
    Length: 274 feet
    Speed; 11 knots cruising
    Contributions: Used as a reasearch vessel by NOAA and WHOI
