Ocean Engineers

Ocean engineers solve problems related to the ocean.  They may design instruments on submersibles that can collect different types of data as well as the ships that carry cargo around the world.  They are not afraid of water for sure!  They are also buoyancy experts knowing about how changing the density of an object affects its ability to sink or float.

2.  Mapping the Ocean Floor

1/31/2013

 
Picture
So before we design a submersible to explore the ocean floor, we better know what the ocean floor looks like!  We wouldn't want a thruster to drive a submersible into a large rock or an underwater cliff.  

One kind of technology that ocean engineers have designed is the sounding pole.  The sounding pole is placed into the water and when it hits the bottom of the ocean floor, a color-coded key tells us how deep the ocean is at the point the sounding pole was placed.

More advanced than the sounding pole is sonar!  Sonar uses sound waves to map the ocean floor, giving us a more accurate representation.  Click here to find out more about sonar technology.

    I love what I do.  No ifs, ands, or buts about it.
