Maritime archaeology is a discipline within archaeology as a whole that specifically studies human interaction with the sea, lakes and rivers through the study of associated physical remains, be they vessels, shore-side facilities, port-related structures, cargoes, human remains and submerged landscapes. A specialty within maritime archaeology is nautical archaeology, which studies ship construction and use.
A shipwreck is the wreckage of a ship that is located either beached on land or sunken to the bottom of a body of water. Shipwrecking may be intentional or unintentional. There were approximately three million shipwrecks worldwide as of January 1999, according to Angela Croome, a science writer and author who specialized in the history of underwater archaeology.
In maritime law, flotsam,jetsam,lagan, and derelict are specific kinds of shipwreck. The words have specific nautical meanings, with legal consequences in the law of admiralty and marine salvage. A shipwreck is defined as the remains of a ship that has been wrecked, whether it has sunk or is floating on the surface of the water.
In property law, lost, mislaid, and abandoned property are categories of the common law of property which deals with personal property or chattel which has left the possession of its rightful owner without having directly entered the possession of another person. Property can be considered lost, mislaid, or abandoned depending on the circumstances under which it is found by the next party who obtains its possession.
Aviation archaeology is a recognized sub-discipline within archaeology and underwater archaeology as a whole. It is an activity practiced by both enthusiasts and academics in pursuit of finding, documenting, recovering, and preserving sites important in aviation history. For the most part, these sites are aircraft wrecks and crash sites, but also include structures and facilities related to aviation. It is also known in some circles and depending on the perspective of those involved as aircraft archaeology or aerospace archaeology and has also been described variously as crash hunting, underwater aircraft recovery, wreck chasing, or wreckology.
Treasure hunting is the physical search for treasure. For example, treasure hunters try to find sunken shipwrecks and retrieve artifacts with market value. This industry is generally fueled by the market for antiquities.
The SS City of Rio de Janeiro was an iron-hulled steam-powered passenger ship, launched in 1878, which sailed between San Francisco and various Asian Pacific ports. On 22 February 1901, the vessel sank after striking a submerged reef at the entry to San Francisco Bay while inward bound from Hong Kong. Of the approximately 220 passengers and crew on board, fewer than 85 people survived the sinking, while 135 others were killed in the catastrophe. The wreck lies in 287 feet (87 m) of water just off the Golden Gate and is listed in the National Register of Historic Places as nationally significant.
The Mansfield Cut Underwater Archeological District is an 18.31-acre (74,100 m2) area located near the city of Port Mansfield, Texas, United States, in the waters off Kenedy County and Willacy County, Texas. Located offshore in the Gulf of Mexico near the Port Mansfield Cut, the underwater archaeological site is the location of the Mansfield Cut Wrecks and has been listed on the National Register of Historic Places since 1974.
The Convention on the Protection of the Underwater Cultural Heritage is a treaty that was adopted on 2 November 2001 by the General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO). The convention is intended to protect "all traces of human existence having a cultural, historical or archaeological character" which have been under water for over 100 years. This extends to the protection of shipwrecks, sunken cities, prehistoric art work, treasures that may be looted, sacrificial and burial sites, and old ports that cover the oceans' floors. The preservation of underwater cultural heritage is significant as it allows for the retelling of numerous historical events. As part of its duty to conduct scientific research and provide continuous education on the importance of underwater cultural heritage, UNESCO strives to maintain these sites for the enjoyment of current and future generations. The convention may provide a customary framework to help raise awareness and seek to combat the illegal looting and pirating occurring in waters worldwide. As an international body, member states of the convention agree to work towards the preservation of sunken cultural property within their jurisdiction and the high seas.
The Black Swan Project is the project name given by Odyssey Marine Exploration for its discovery and recovery of an estimated US$500 million worth of silver and gold coins from the ocean floor. Initially Odyssey kept the origin of the treasure confidential. It was later proved in trial that the recovered cargo was being carried by the Spanish frigate Nuestra Señora de las Mercedes, which was sunk by the British Royal Navy off Portugal in 1804.
HMS Fowey was a fifth rate warship of the Royal Navy, launched on 14 August 1744 in Hull, England. She spent only four years in commission before she struck a reef and sank in what is known today as Legare Anchorage in Biscayne National Park, off the coast of Florida. She was armed with six, nine, and eighteen pounder guns and crewed with over 200 men.
The Whitefish Point Underwater Preserve was established in 1987 to protect and conserve shipwrecks and historical resources on 376 square miles (970 km2) of Lake Superior bottomlands in Whitefish Bay and around Whitefish Point, Michigan. The formation of the Michigan Underwater Preserves helped stop controversy over artifact removal from shipwrecks of this area. The preserve is now known for deep, well preserved shipwrecks in clear water accessible to scuba divers with technical skill and experience. The preserve is one of the last places in the Great Lakes to observe shipwrecks without zebra mussel encrustation.
P2 – Svenskt Vrakskydd is an organization that was started by scuba divers. The purpose was to work for the preservation of shipwrecks in Swedish waters. The organization works through spreading information and debating. For example, the organization has produced a pamphlet for divers that is called “Wreck Ethics”. “Wreck Ethics” is about how to dive amongst wrecks carefully, with tips on how you anchor to do minimum damage possible on wrecks.
The Henry Chisholm was a wooden freighter that sank off the shore of Isle Royale in Lake Superior in 1898 and the remains are still on the lake bottom. The wreck was placed on the National Register of Historic Places in 1984.
SS Monarch was a passenger-package freighter built in 1890 that operated on the Great Lakes. She was sunk off the shore of Isle Royale in Lake Superior in 1906 and the remains of her wreck and cargo are still on the lake bottom. The wreck was placed on the National Register of Historic Places in 1984.
Gallinipper was a schooner that sank in Lake Michigan off the coast of Centerville, Manitowoc County, Wisconsin, United States. In 2010, the shipwreck site was added to the National Register of Historic Places.
The R.M.S. Titanic Maritime Memorial Act of 1986 is a United States Act of Congress that was passed to designate the wreck of the RMS Titanic as an international maritime memorial and to regulate the research, exploration and salvage of the wreckage. The Act became law on October 21, 1986, when it was passed by the 99th United States Congress.
Anxious Bay is a bay in the Australian state of South Australia located on the west coast of Eyre Peninsula about 275 kilometres west north-west of Adelaide. It was named by Matthew Flinders on 21 February 1802. It is one of four ‘historic bays’ located on the South Australian coast.
The conservation and restoration of shipwreck artifacts is the process of caring for cultural heritage that has been part of a shipwreck. Oftentimes these cultural artifacts have been underwater for a great length of time. Without conservation, most artifacts would perish and important historical data would be lost. In archaeological terms, it is usually the responsibility of an archaeologist and conservator to ensure that material recovered from a shipwreck is properly cared for. The conservation phase is often time-consuming and expensive, which is one of the most important considerations when planning and implementing any action involving the recovery of artifacts from a shipwreck.
The Agreement Concerning the Shipwrecked Vessel RMS Titanic is a treaty open to all states regarding the protection of the shipwreck of the RMS Titanic. Following the passage of the RMS Titanic Maritime Memorial Act in 1986, the United States began negotiations in 1997 with the United Kingdom, France, and Canada toward an agreement to protect the wreck. The agreement was signed by the UK in 2003 and by the US in 2004. It was not until 2019 that the US ratified the agreement, bringing it into effect on 18 November, the day of deposit of the instrument of ratification.
