What are underground cables in the sea for?
How does it get there?

The ones the company I work for are for data transmission- Phone calls, internet and such. Certain places around the world make the cable- Newington NH, Hitachi Japan, Calais France,...and we take our ship there to pick it up. The cable comes in through the back end of the ship and goes into large, round rooms called tanks where it is coiled up around the edge to the center and then back out. Depending on the diameter of the cable- from 1/4 to 2 1/2 inches, the ship can carry up to 8,000 miles of cable. The actual data transmission part of the cable is only a 100th of an inch or so wide- the rest is armor to keep the cable from breaking or getting bitten by sharks-- yes, it does happen. To put it on the ocean bottom, it's just paid out the back of the ship as we slowly (0.1-7 mph) move along; it sinks to the bottom and stays there by it's weight. YouTube has some good videos of it.

Communications between continents. They were laid by ship.

Energy and communications. Cable laying ships place them on the ocean floor.

Underground cables are buried under ground. Cables in the sea are submerged and are there for various reasons including telephone and electricity from, for example, wind turbines.
