Keeping the Internet Working

By Brad

The site PopSci has an interesting article on some of the people who keep the Internet alive and well and working beneath sea level:

For the past five years, John Rennie has braved the towering waves of the North Atlantic Ocean to keep your e-mail coming to you. As chief submersible engineer aboard the Wave Sentinel, part of the fleet operated by U.K.-based undersea installation and maintenance firm Global Marine Systems, Rennie—a congenial, 6’4”, 57-year-old Scotsman—patrols the seas, dispatching a remotely operated submarine deep below the surface to repair undersea cables. The cables, thick as fire hoses and packed with fiber optics, run everywhere along the seafloor, ferrying phone and Web traffic from continent to continent at the speed of light.

The cables regularly fail. On any given day, somewhere in the world there is the nautical equivalent of a hit and run when a cable is torn by fishing nets or sliced by dragging anchors. If the mishap occurs in the Irish Sea, the North Sea or the North Atlantic, Rennie comes in to splice the break together.

On one recent expedition, Rennie and his crew spent 12 days bobbing in about 250 feet of water 15 miles off the coast of Cornwall in southern England looking for a broken cable linking the U.K. and Ireland. Munching fresh doughnuts (a specialty of the ship’s cook), Rennie and his team worked 12-hour shifts exploring the rocky seafloor with a six-ton, $10-million remotely operated vehicle (ROV) affectionately known as “the Beast.”
