Documentaries 2015 Rescue at Sea Documentary on Shipwreck Rescue
A shipwreck is the remains of a ship that has wrecked, which are found either beached on land or sunken to the bottom of a body of water. Shipwrecking may be deliberate or accidental. UNESCO estimates that worldwide over 3 million shipwrecks, some thousands of years old, lie on seabeds.
Very few shipwrecks are as famous as the catastrophic Titanic, Britannic, Lusitania, Estonia, Empress of Ireland, Andrea Doria, or Costa Concordia. There are also thousands of wrecks that were not lost at sea but have been abandoned or sunk. These abandoned, or derelict ships are typically smaller craft, such as fishing vessels. They may pose a hazard to navigation and may be removed by port authorities. There are more than 3 million wrecks on the ocean floor, the United Nations estimates.
