Pressure Proof Diving Suits
Pressure proof diving suits are used to go to depths of the ocean that have too much pressure for the human body to withstand. They were first invented to aid in salvage work. (Navigation) -
Modern Trawls
Trawls are used for collecting organisms in the water. They are large nets carried behind a boat. (Trade) -
Steamboats
The first steamboats were invented for faster travel. These would eventually lead to the invention of other faster forms of aquatic travel. The first steamboat was the Clermont. (Navigation) -
Magnetometer
Magnetometers are used to measure changes in the Earth's magnetism. They were invented in 1832, but weren't used for marine uses until the 1960s. (Scientific Research) -
Submersible Pump
The submersible pump was invented to be attached to the first underwater engine. It is used primarily for collection of samples. (Scientific Research) -
Hydrophones
The first hydrophones were used to detect bells rung by lighthouses and ships. They are used for listening to underwater sound. (Navigation/Military) -
GIS
GIS, or Geographical Information Systems, were invented to map out large areas within a computer. The first ideas of GIS were made in the early 1960s with the use of computers. (Navigation) -

Multibeam sonar is a form of sonar that uses beamforming to map out the ocean floor. (Navigation) -
Acoustic Doppler Current Profiler
While in 1903, the first mechanical flow meter was invented, the first Acoustic Doppler Current Profiler, or ADCP, was invented. This device measures the speed and direction of currents. (Scientific Research/Navigation)
