NOAA Ocean Today explores shipwrecks! Ocean Exploration is all about new discoveries, and shipwrecks are one of the most fascinating expeditions of all. The unsinkable Titanic, the civil war ironclad USS Monitor, and literally millions of unknown or unidentified ships lie waiting for searchers brave and resourceful enough to unlock their secrets.

Every ship tells us something and some change the way we think about history. To crack these time capsules, explorers must overcome crushing pressures, darkness, deadly storms, and the hardest challenge of all--finding out where to look in our 140 million square miles of ocean. Explore shipwrecks through the videos on their site.
