Ocean depth record

In 1954, an ocean exploration depth record of 13,287 feet (4,050 meters, over 2,000 fathoms, or over 2-1/2 miles) in FNRS III was set when two French Navy officers, Lt. Commander Georges Houot and Lt. Pierre Willm, reached the Atlantic Ocean floor, 120 miles southwest of Dakar, Senegal, Africa, in the tropical Atlantic Ocean.The French research submersible they used was untethered and self-propelled, designed by Auguste Piccard, and built by the French Navy. This exceeded Otis Barton's 1948 diving record of 4,500 feet (1,372 meters) off the coast of California in a tethered modified bathysphere.[Image: cutaway view of FNRSIII]
