  • Period: to

    Challenger Expedition

    The Challenger circumnavigates the globe. This is the first huge aceanographic expedition. (the last date is wrong exept the year)
  • Gorringe Bank

    H.H. Gorringe, discovered an undersea mountain 130 miles west of Portugal. They found it when they were conducting sound tests with a Thompson sound machine.
  • Steel rope

    (only the year is right) The Coast Survey Steamr Blake is the first ship to use steel rope for oceanographic purposes.
  • Titanic

    The White Star Liner Titanic sinks when it hit an iceberg in the North Atlantic Ocean. This peaked the intrest to find a devise that could discover objects using echolocation while a ship was moving.
  • Acoustic exploration

    Reginald Fessenden used a Fessenden Oscillator to reglect a signal off an iceberg and at the same time reflect an acustic signal off the seabottom. This was the beginning of the acoustic exploration of the sea.
  • Period: to

    World War I

    (only the years are right) World War I causes aceanic acoustic research to increase. Both the Navy and Army developed a way to find enemy submarines.
  • First line of soundings

    French scientist succeed in running the first line of sounding obtained from an acoustic echo sounder.
  • Period: to

    Mid-Atlatic ridge continuity

    (only the years are right) The German Meteor expedition proves that the Mid-Atlantic ridge does in fact continue North. They used echo-sounding equipment and other oceanographic instruments.
  • Manned exploration of the sea

    (only the year is right) Edward Beebe was lowered in a tethered bathyscaph to a depth of 3,028 feet.
  • untethered sesearch submersibles

    The French research submersible F.N.R.S. 3 dives to 13,257 feet. This is the begining of manned untethered research submersibles.
  • Thermal vents

    (only the year is right) Thermal vents are found along with an ecosystem that does not need energy from the sun. The organisms use chemosynthesis to atain energy.
  • Titanic discovered!!!!

    Dr. Robert Ballard discovers the Titanic.
