Susan Casey is an accomplished journalist who's spent years writing about the ocean, and most recently, the deep sea. The deep sea generally starts around 600 feet below the surface where you could no longer see the light from above, but it goes way beyond that. In some places, the ocean is almost seven miles deep. Susan is one of the few people who's gone deeper than 5,000 meters in a submersible, which is over three miles down to the ocean floor.
