Deep-diving Alvin went on some epic adventures exploring the ocean floor.
On September 1, 1985, underwater explorer Robert Ballard located the world's most famous shipwreck. The Titanic lay largely intact at a depth of 12,000 feet off the coast of St. John's, Newfoundland.For almost 50 years, the deep-diving Alvin has been exploring the ocean floor - even retrieving a lost nuclear bomb between some notable scientific discoveries.
And that will make U.S. ocean research programs competitive again with Russia, China, Japan and France - all of which have vessels that can go deeper than Alvin, said Joseph Crouch, manager of the marine structures and engineering section at the institute. "Unfortunately," he said,"today only about 60 percent of the earth's oceans are available to the United States for ... research. That leaves 40 percent still unreachable to us."
