The way a submarine dives and resurfaces is because of buoyancy. Buoyancy is sort of like an upward force that things of many sizes afloat, it can be anything from something small like a barrel to a gigantic ship.

One of the most important and amusing jobs in the ocean engineering industry is a marine engineer.

When we are thinking about brine pools, we need you to imagine a hole at the bottom of the ocean. These holes, brine pools, are the saltiest parts of the entire ocean. They are essentially lakes of death, with barely anything able to survive within them. 

Jacques Piccard was one of the men who achieved this goal, he not only achieved it but at the time he broke the record of the lowest recorded depth in the ocean (7 miles deep). They had descended for about five hours to reach a depth of  35,797 feet, at the bottom of the Mariana trench.

Some examples of what they build are aircraft carriers, submarines, sailboats, and tankers. They make around $45.89 per hour and $95,440 per year.

He designed one of the first recorded submarines.

Underwater vehicles are categorized in four classes: Human Occupied Vehicles (HOVs), Remotely Operated Vehicles (ROVs), Autonomous Underwater Vehicles (AUVs), Hybrid Remotely Operated Vehicles (HROVs).

Marine engineers can be also found at all over the places fixing and researching dangerous things, a place that a marine engineer could be at is the water treatment plant facilities to finding recycling services that can maintain a safe and healthy environment. Without these Marine engineers helping the planet with all sorts of things, the humans wouldn't be able to survive on the planet.
