People have long explored the surface of the ocean. Since prehistoric times the sea has been a source of food and transportation. People explored perhaps out of curiosity to find the boundaries, to find out how large this watery world is, and where it ends?....if it ends?
Every time and every place explorers look they are surprised... by previously undiscovered species, by new ecosystems such as hydrothermal vent systems, by storms hidden in the depths of the ocean.
