Gallery: Lost in the Bermuda Triangle

Murky Depths

Retrieving sunken planes and ships from the Bermuda Triangle is especially difficult because it is home to the Puerto Rico Trench, which reaches depths of about 30,100 feet (9,200 meters) and is the deepest part of the Atlantic Ocean. Crafts that sink to such low points are seldom seen again. This underwater photo shows an unidentified Caribbean shipwreck discovered by NOAA oceanography researchers on April 1, 2011.
