  • First Submarine

    First Submarine
    The world’s first submarine was built in 1620 by a dutch physician named Cornelis Drebbel. The boat is covered in leather and is made of wood with iron reinforced in it. The inside of the boat has six seats on each side fitting twelve oarsmen. The oars stick out the sides of the boat and have leather sleeves that tightly fit around the sides so water can’t get in. Drebbel used the submarine multiple times in the Thames River and went twelve to fifteen feet deep.
  • First Enclosed Diving Device

    First Enclosed Diving Device
    Englishman John Lethbridge developed the first enclosed diving device. He made a one- man diving dress that was completely enclosed. The device was made of a barrel of air covered in leather, a glass porthole for viewing, and watertight sleeves connected to two arm holes. Also in 1715 Chevalier de Beauve developed the first waterproof suit. The suit has a helmet with two leather tubes attached to the helmet and the surface which supplies air.

  • First use of Scuba

    First use of Scuba
    The first use of scuba was in 1825. An underwater breathing apparatus knows as a scuba was developed by William H. James.

  • The voyage of the H.M.S. Challenge

    The voyage of the H.M.S. Challenge
    The voyage of the H.M.S. Challenger began a four year trip around the world starting in Portsmouth, England. Scientists tested the temperature, density, and salinity of the seawater. They collected information about meteorology, ocean currents, and sediment. The scientist discovered hundreds of species that were unknown and discovered chains of underwater mountains. All the research found was put together into The Challenger Report. This voyage displayed the basis of modern oceanography.
  • Mid-Atlantic Ridge

     Mid-Atlantic Ridge
    In 1953 the Mid-Atlantic Ridge was discovered. An american geologist named Marie Tharp discovered a rift valley in the Atlantic Ocean. They later found that the rift valley continued 40,000 miles along the ocean floor. The finding of the ridge provides evidence for the theory of continental drift. This continental drift is known now today as plate tectonics.
  • The first solo drive to the Mariana Trench (present day)

    The first solo drive to the Mariana Trench (present day)
    The first solo drive to the Mariana Trench was on March 25, 2012. James Cameron was the first person to do a solo dive to the bottom of the deepest part of the ocean, the Mariana Trench. He dived to the bottom which was about 35,756 feet deep and seven miles down. When he was on the bottom he spent about three hours filming and then returned to the surface. He was filming because he is a Hollywood director.
