148-736: A glacial-fed lake, Arctic waters, the Great Lakes , etc.) slows the degradation of organic ship materials. Decay, corrosion and marine encrustation are inhibited or largely absent in cold waters. Many modern shipwrecks contribute to marine pollution , mainly as sources of significant oil spills . A 2005 survey of shipwrecks since 1890 found that over 8,500 of the submerged wrecks may still contain oil. Oil spills can have devastating effects on marine and coastal environments as well as fisheries. In addition to being toxic to marine life, polycyclic aromatic hydrocarbons (PAHs), found in crude oil , are very difficult to clean up, and last for years in
222-572: A blanket ban on all diving; for other wrecks divers may visit provided they do not touch, interfere with or penetrate the wreck. In the United States, shipwrecks in state waters are regulated by the Abandoned Shipwrecks Act of 1987. This act is much more lenient in allowing more open access to the shipwrecks. Following the beaching of MSC Napoli , as a result of severe damage incurred during European storm Kyrill , there

Amphora is a Greco-Roman word developed in ancient Greek during the Bronze Age . The Romans acquired it during the Hellenization that occurred in
370-446: A certain age, the original owner may have lost all claim to the cargo. Anyone who finds the wreck can then file a salvage claim on it and place a lien on the vessel, and subsequently mount a salvage operation (see Finders, keepers ). The State of North Carolina questionably claims "all photographs, video recordings, or other documentary materials of a derelict vessel or shipwreck or its contents, relics, artifacts, or historic materials in
444-438: A characteristic red fabric. It was very heavy, although also strong. Around the middle of the 1st century BC the so-called Dressel 2-4 starts to become widely used. This type of amphora presented some advantages in being lighter and with thinner walls. It has been calculated that while a ship could accommodate approximately 4500 Dressel 1, it was possible to fit 6000 Dressel 2–4 in the same space. Dressel 2-4 were often produced in
518-512: A fancy shape for high-quality decorative ceramics, and continued to be produced there long after they had ceased to be used further west. Besides coarse amphorae used for storage and transport, the vast majority, high-quality painted amphorae were produced in Ancient Greece in significant numbers for a variety of social and ceremonial purposes. Their design differs vastly from the more functional versions; they are typified by wide mouth and
592-697: A general analysis of the Western Mediterranean types see Panella, and Peacock and Williams. Ceramics of shapes and uses falling within the range of amphorae, with or without handles, are of prehistoric heritage across Eurasia, from the Caucasus to China. Amphorae dated to approximately 4800 BC have been found in Banpo , a Neolithic site of the Yangshao culture in China . Amphorae first appeared on
666-782: A greater or lesser degree in an Australian case and in a Norwegian case. The American courts have been inconsistent between states and at federal level. Under Danish law, all shipwrecks over 150 years old belong to the state if no owner can be found. In Spain, wrecks vest in the state if not salvaged within 3 years. In Finland, all property on board shipwrecks over 100 years old vests in the state. The British Protection of Wrecks Act , enacted to protect historic wrecks, controls access to wrecks such as Cattewater Wreck which can only be visited or investigated under licence. The British Protection of Military Remains Act 1986 also restricts access to wrecks which are sensitive as war graves . The Protection of Military Remains Act in some cases creates
740-417: A neck amphora, the handles are attached to the neck, which is separated from the belly by an angular carination. There are two main types of neck amphorae: There are also some rarer special types of neck amphora, distinguished by specific features, for example: In contrast to the neck amphora, a belly amphora does not have a distinguished neck; instead, the belly reaches the mouth in a continuous curve. After
814-479: A ring base, with a glazed surface and decorated with figures or geometric shapes. They normally have a firm base on which they can stand. Panathenaic amphorae were used as prizes in the Panathenaic Festivals held between the 6th century BC to the 2nd century BC, filled with olive oil from a sacred grove. Surviving examples bear the inscription "I am one of the prizes from Athens", and usually depict

The necks of amphorae are narrow for pouring by a person holding it by the bottom and a handle. Some variants exist. The handles might not be present. The size may require two or three handlers to lift. For the most part, however, an amphora
962-451: A ship's crew has died or abandoned the ship, and the ship has remained adrift but unsunk, they are instead referred to as ghost ships . Historic wrecks are attractive to maritime archaeologists because they preserve historical information: for example, studying the wreck of Mary Rose revealed information about seafaring, warfare, and life in the 16th century. Military wrecks, caused by a skirmish at sea, are studied to find details about
1036-461: A shipwreck) and adventurae maris (material still at sea), which are treated differently by some, but not all, legal systems. Wrecks are often considered separately from their cargo. For example, in the British case of Lusitania [1986] QB 384 it was accepted that the remains of the vessel itself were owned by the insurance underwriters who had paid out on the vessel as a total loss by virtue of
1110-785: A treasure almost three miles (16,000 ft; 4,800 m) deep. A U.S. federal court and a panel from the United States Court of Appeals for the Eleventh Circuit have upheld the Spanish claim to the contents of the ship Nuestra Señora de las Mercedes ; Spain took control of the treasure in February 2012. A very small number of coins and effects recovered from the ship were deposited in Gibraltar, because they showed clear signs coherent with an internal explosion on
1184-719: Is Queen Anne's Revenge which is undergoing archaeological recovery by the North Carolina Department of Cultural Resources near Beaufort Inlet, NC. An important international convention aiming at the protection of underwater cultural heritage (including shipwrecks) is the Convention on the Protection of the Underwater Cultural Heritage. The 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage represents
1258-611: Is a type of container with a pointed bottom and characteristic shape and size which fit tightly (and therefore safely) against each other in storage rooms and packages, tied together with rope and delivered by land or sea. The size and shape have been determined from at least as early as the Neolithic Period. Amphorae were used in vast numbers for the transport and storage of various products, both liquid and dry, but mostly for wine. They are most often ceramic , but examples in metals and other materials have been found. Versions of
1332-492: Is an international treaty aimed exclusively at the protection of underwater cultural heritage and the facilitation of international cooperation in this regard. It does not change sovereignty rights of States or regulate the ownership of wrecks or submerged ruins. In 2011, the most valuable cargo of a sunken shipwreck was identified near the western edge of the Celtic Sea . This World War II era sinking of Gairsoppa led to
1406-410: Is based primarily on the study of modern amphora production in some areas of the eastern Mediterranean. Amphorae often were marked with a variety of stamps, sgraffito , and inscriptions. They provided information on the production, content, and subsequent marketing. A stamp usually was applied to the amphora at a partially dry stage. It indicates the name of the figlina (workshop) and/or the name of
1480-555: Is that any such finds and recovery must be reported within 28 days to the Receiver of Wreck . Failure to do so is an offence under the Merchant Shipping Act and can result in a criminal record for theft by finding . After several days, the police and Receiver of Wreck, in conjunction with the landowner and the contracted salvors , established a cordon to prevent access to the beach. A similar situation occurred after
1554-406: Is the historical value of the shipwreck that counts as well as any slight piece of information or evidence that is acquired. Exposed wooden components decay quickly. Often the only wooden parts of ships that remain after a century are those that were buried in silt or sand soon after the sinking. An example of this is Mary Rose . Steel and iron , depending on their thickness, may retain

#17327722974251628-433: 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 (an estimate rapidly endorsed by UNESCO and other organizations ). When

1776-512: The Great Lakes of North America, have remained intact with little degradation. In some sea areas, most notably in Gulf of Bothnia and Gulf of Finland , salinity is very low, and centuries-old wrecks have been preserved in reasonable condition. However, bacteria found in fresh water cause the wood on ships to rot more quickly than in seawater unless it is deprived of oxygen. Two shipwrecks, USS Hamilton and USS Scourge , have been at

The two spellings are transcriptions of amphiphorēwes (plural) and amphorēwe (dual) in Mycenaean Greek from which it may be seen that the short form prevailed on the mainland. Homer uses
1924-684: The Phoenician coast at approximately 3500 BC. In the Bronze and Iron Ages amphorae spread around the ancient Mediterranean world, being used by the ancient Greeks and Romans as the principal means for transporting and storing grapes , olive oil , wine , oil , olives , grain , fish , and other commodities . They were produced on an industrial scale until approximately the 7th century AD. Wooden and skin containers seem to have supplanted amphorae thereafter. They influenced Chinese ceramics and other East Asian ceramic cultures, especially as
1998-682: The Roman Republic . Cato is the first known literary person to use it. The Romans turned the Greek form into a standard -a declension noun, amphora , pl. amphorae . Undoubtedly, the word and the vase were introduced to Italy through the Greek settlements there, which traded extensively in Greek pottery. It is remarkable that even though the Etruscans imported, manufactured, and exported amphorae extensively in their wine industry, and other Greek vase names were Etruscanized, no Etruscan form of
2072-615: The sediment and marine environment. Shipwreck pollution may also originate with a ship's cargo or munitions, such as unexploded ordnance or chemical weapons canisters. German trawler V 1302 John Mahn , sunk in the North Sea in 1942, has multiple unexploded depth charges on board which render the wreck hazardous. Samples taken from the wreck and nearby sediment show the presence of heavy metals like nickel and copper, polycyclic aromatic hydrocarbons , arsenic and explosive compounds into surrounding waters, which have changed
2146-655: The 2nd and the 1st century BC due to the distribution of land to military veterans and the founding of new colonies. Spanish amphorae were widespread in the Mediterranean area during early imperial times. The most common types were all produced in Baetica and among these there were the Dressel 20, a typical olive oil container, the Dressel 7–13, for garum (fish sauce), and the Haltern 70, for defrutum (fruit sauce). In
2220-491: The German government, although Nazi Germany (the government at the time) is long-defunct. Many military wrecks are also protected by virtue of being war graves . However, many legal systems allow the rights of salvors to override the rights of the original owners of a wreck or its cargo. As a general rule, non-historic civilian shipwrecks are considered fair game for salvage. Under international maritime law , for shipwrecks of
2294-576: The Maña C1 and C2, later renamed Van der Werff 1, 2, and 3. In the Aegean area the types from the island of Rhodes were quite popular starting from the 3rd century BC due to local wine production which flourished over a long period. These types developed into the Camulodunum 184, an amphora used for the transportation of Rhodian wine all over the empire. Imitations of the Dressel 2-4 were produced on

2368-723: The Tarraconensis region the Pascual 1 was the most common type, a wine amphora shaped on the Dressel 1, and imitations of Dressel 2–4. North-African production was based on an ancient tradition which may be traced back to the Phoenician colony of Carthage . Phoenician amphorae had characteristic small handles attached directly onto the upper body. This feature becomes the distinctive mark of late-Republican/early imperial productions, which are then called neo-Phoenician. The types produced in Tripolitania and Northern Tunisia are
2442-477: The amphorae were one of many shapes used in Ancient Greek vase painting . The amphora complements a vase, the pithos , which makes available capacities between one-half and two and one-half tons. In contrast, the amphora holds under a half-ton, typically less than 50 kilograms (110 lb). The bodies of the two types have similar shapes. Where the pithos may have multiple small loops or lugs for fastening

Some examples bear the inscription "ΤΩΝ ΑΘΗΝΗΘΕΝ ΑΘΛΩΝ" meaning "[I am one] of the prizes from [the goddess] Athena". They contained the prize of oil from the sacred olive tree of the goddess Athena for the winners of the athletic contests held to honour the goddess, and were evidently kept thereafter, and perhaps used to store wine, before being buried with

Wrecks typically decay rapidly when in seawater . There are several reasons for this: An important factor in the condition of the wreck is the level of destruction at the time of the loss or shortly afterwards due to the nature of the loss, salvage or later demolition. Examples of severe destruction at
2738-549: The catastrophic Titanic , MV Doña Paz , Britannic , Lusitania , Estonia , Empress of Ireland , Andrea Doria , Endurance 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 . Poor design, improperly stowed cargo , navigation and other human errors leading to collisions (with another ship,
2812-477: The ceramic ateliers in Marseille during late Augustan times. The type Oberaden 74 was produced to such an extent that it influenced the production of some Italic types. Spanish amphorae became particularly popular thanks to a flourishing production phase in late Republican times. The Hispania Baetica and Hispania Tarraconensis regions (south-western and eastern Spain) were the main production areas between
2886-590: The custody of any agency of North Carolina government or its subdivisions" to be its property. Some countries assert claims to all wrecks within their territorial waters, irrespective of the interest of the original owner or the salvor. Some legal systems regard a wreck and its cargo to be abandoned if no attempt is made to salvage them within a certain period of time. English law has usually resisted this notion (encouraged by an extremely large maritime insurance industry, which asserts claims in respect of shipwrecks which it has paid claims on), but it has been accepted to
2960-448: The damage of marine creatures that create a home out of them, primarily octopuses and crustaceans. These creatures affect the primary state because they move, or break, any parts of the shipwreck that are in their way, thereby affecting the original condition of amphorae , for example, or any other hollow places. Finally, in addition to the slight or severe destruction marine animals can create, there are also "external" contaminants, such as

Most were produced with a pointed base to allow upright storage by embedding in soft ground, such as sand. The base facilitated transport by ship, where the amphorae were packed upright or on their sides in as many as five staggered layers. If upright, the bases probably were held by some sort of rack, and ropes passed through their handles to prevent shifting or toppling during rough seas. Heather and reeds might be used as packing around

3108-636: The exceptional amphora deposit uncovered in Rome in Castro Pretorio at the end of the 1800s, he collected almost 200 inscriptions from amphorae and included them in the Corpus Inscriptionum Latinarum . In his studies of the amphora deposit he was the first to elaborate a classification of types, the so-called "Dressel table", which still is used today for many types. Subsequent studies on Roman amphorae have produced more detailed classifications, which usually are named after
3182-813: The historic event; they reveal much about the battle that occurred. Discoveries of treasure ships , often from the period of European colonisation , which sank in remote locations leaving few living witnesses, such as Batavia , do occur as well. Some contemporary wrecks, such as the oil tanker Prestige or Erika , are of interest primarily because of their potential harm to the environment. Other contemporary wrecks are scuttled in order to spur reef growth, such as Adolphus Busch and Ocean Freeze . Many contemporary and historic wrecks, such as Thistlegorm , are of interest to recreational divers that dive to shipwrecks because they are interesting to explore, provide large habitats for many types of marine life, and have an interesting history. Well-known shipwrecks include

It forms part of a group of UNESCO standard setting instruments regarding the domain of cultural heritage, encompassing seven conventions adopted by UNESCO Member States, which constitute a coherent and complementary body guaranteeing a complete protection of all forms of cultural heritage. The UNESCO 2001 Convention
3330-412: The island of Cos for the transportation of wine from the 4th century BC until middle imperial times. Cretan containers also were popular for the transportation of wine and can be found around the Mediterranean from Augustan times until the 3rd century AD. During the late empire period, north-African types dominated amphora production. The so-called African I and II types were widely used from the 2nd until
3404-433: The late 4th century AD. Other types from the eastern Mediterranean (Gaza), such as the so-called Late Roman 4, became very popular between the 4th and the 7th century AD, while Italic productions ceased. The largest known wreck of an amphorae cargo ship, carrying 6,000 pots, was discovered off the coast of Kefalonia , an Ionian island off the coast of Greece . Some modern winemakers and brewers use amphorae to provide
3478-410: The law of subrogation (who subsequently sold their rights), but that the property aboard the wreck still belonged to its original owners or their heirs. Military wrecks, however, remain under the jurisdiction – and hence protection – of the government that lost the ship, or that government's successor. Hence, a German U-boat from World War II still technically belongs to
3552-450: The local microbial ecology. Iron and steel wrecks are subject to corrosion, which is most rapid in shallow sea water where the salinity induces galvanic corrosion, oxygen content is high and water movement replenishes the oxygen rapidly. In deeper water and in still water the corrosion rates can be greatly reduced. Corrosion rates of iron and steel are also reduced when concretions, solid layers of rust, or layers of marine organisms separate

The largest stands as tall as 1.5 metres (4.9 feet) high, while some were less than 30 centimetres (12 inches) high - the smallest were called amphoriskoi (literally "little amphorae"). Most were around 45 centimetres (18 inches) high. There

Ships that sink upright onto a sand bottom tend to settle into the sand to a similar level to that at which they would normally float at the surface. The thinner materials of the upper works tend to break up first, followed by the decks and deck beams, and the hull sides unsupported by bulkheads. The bow and stern may remain relatively intact for longer as they are usually more heavily constructed. Heavy machinery like boilers, engines, pumps, winches, propellers, propeller shafts, steering gear, anchors and other heavy fittings also last longer and can provide support to
3774-542: The mid-5th century BC, this type was rarely produced. The pelike is a special type of belly amphora, with the belly placed lower, so that the widest point of the vessel is near its bottom. The pelike was introduced around the end of the 6th century BC. Another special type is the Panathenaic prize amphora , with black-figure decoration, produced exclusively as prize vessels for the Panathenaia and retaining

#17327722974253848-405: The owner of the workshop. Painted stamps, tituli picti , recorded the weight of the container and the contents, and were applied after the amphora was filled. Today, stamps are used to allow historians to track the flow of trade goods and recreate ancient trade networks. The first systematic classification of Roman amphorae types was undertaken by the German scholar Heinrich Dressel . Following
3922-544: The particular event they were awarded for. Painted amphorae were also used for funerary purposes, often in special types such as the loutrophoros . Especially in earlier periods, outsize vases were used as grave markers, while some amphorae were used as containers for the ashes of the dead. By the Roman period vase-painting had largely died out, and utilitarian amphorae were normally the only type produced. Various different types of amphorae were popular at different times: On
3996-404: The prize-winner. They depicted goddess Athena on one side (as seen on the second image on this page) and the athletic event on the other side, e.g. a scene of wrestling or running contest etc. By the Roman period utilitarian amphorae were normally the only type produced. The first type of Roman amphora, Dressel 1, appears in central Italy in the late 2nd century BC. This type had thick walls and
4070-406: The remaining hull, or cause it to collapse more rapidly. Vessels that come to rest upside down on a yielding seabed can be relatively stable, although the upper decks usually collapse under the load and machinery and fittings fall. Wrecks that rest on their side tend to deteriorate quickly, as the loads are not what they were designed to support, and poorly supported hull sides give way fairly soon and
4144-469: The same workshops used for the production of Dressel 1 which quickly ceased to be used. At the same time in Cuma (southern Italy) the production of the cadii cumani type starts (Dressel 21–22). These containers were mainly used for the transportation of fruit and were used until the middle imperial times. At the same time, in central Italy, the so-called Spello amphorae, small containers, were produced for
4218-471: The scholar who studied them. For the neo-Phoenician types see the work by Maña published in 1951, and the revised classification by Van der Werff in 1977–1978. The Gallic amphorae have been studied by Laubenheimer in a study published in 1989, whereas the Cretan amphorae have been analyzed by Marangou-Lerat. Beltràn studied the Spanish types in 1970. Adriatic types have been studied by Lamboglia in 1955. For

They were not returned to Spain until 2013, when a court finally ordered Odyssey Marine to return the missing pieces. Archaeologist Valerios Stais discovered one of the most notable instruments of time keeping and prediction of celestial events off the coast of the Greek island Antikythera on May 17, 1902. The device, known as
4366-490: The ship's structure for decades. As corrosion takes place, sometimes helped by tides and weather, the structure collapses. Thick ferrous objects such as cannons , steam boilers or the pressure vessel of a submarine often survive well underwater in spite of corrosion. Propellers , condensers , hinges and port holes were often made from non-ferrous metals such as brass and phosphor bronze , which do not corrode easily. Shipwrecks in some freshwater lakes, such as
4440-407: The shoreline, an iceberg, etc.), bad weather, fire , and other causes can lead to accidental sinking. Intentional reasons for sinking a ship include: intending to form an artificial reef ; destruction due to warfare , piracy , mutiny or sabotage ; using the vessel for target practice ; or removing a menace to navigation. A ship can be also used as breakwater structure . Many factors determine
4514-402: The state of preservation of a wreck: The above - especially the stratification (silt/sand sediments piled up on the shipwrecks) and the damages caused by marine creatures - is better described as "stratification and contamination" of shipwrecks. The stratification not only creates another challenge for marine archaeology, but also a challenge to determine its primary state, i.e. the state that it
SECTION 60
#17327722974254588-409: The time of loss are: After the loss, the vessel's owners may attempt to salvage valuable parts of the ship and its cargo. This operation can cause further damage. Shipwrecks in shallow water near busy shipping lanes are often demolished or removed to reduce the danger to other vessels. On charts, some wreck symbols have a line under the symbol with a depth mark, which indicates the water depth above
4662-661: The transportation of wine. On the Adriatic coast the older types were replaced by the Lamboglia 2 type, a wine amphora commonly produced between the end of the 2nd and the 1st century BC. This type develops later into the Dressel 6A which becomes dominant during Augustan times. In the Gallic provinces the first examples of Roman amphorae were local imitations of pre-existent types such as Dressel 1, Dressel 2–4, Pascual 1, and Haltern 70. The more typical Gallic production begins within
4736-588: The vases. Racks could be used in kitchens and shops. The base also concentrated deposits from liquids with suspended solid particles, such as olive oil and wines. Amphorae are of great use to maritime archaeologists , as they often indicate the age of a shipwreck and the geographic origin of the cargo. They are occasionally so well preserved that the original content is still present, providing information on foodstuffs and mercantile systems. Amphorae were too cheap and plentiful to return to their origin-point and so, when empty, they were broken up at their destination. At
4810-440: The whole or part of the ship, its cargo, or its equipment. An example was the salvage of the scuttled German High Seas Fleet at Scapa Flow in the 1920s and 1930s. The unauthorized salvage of wrecks is called wrecking . Shipwreck law determines important legal questions regarding wrecks, perhaps the most important question being the question of ownership. Legally wrecks are divided into wreccum maris (material washed ashore after
4884-552: The word exists. There was perhaps an as yet unidentified native Etruscan word for the vase that pre-empted the adoption of amphora . The Latin word derived from the Greek amphoreus ( ἀμφορεύς ), a shortened form of amphiphoreus ( ἀμφιφορεύς ), a compound word combining amphi- ("on both sides", "twain") and phoreus ("carrier"), from pherein ("to carry"), referring to the vessel's two carrying handles on opposite sides. The amphora appears as 𐀀𐀠𐀡𐀩𐀸 , a-pi-po-re-we , in

Historic wrecks (often but not always defined as being more than 50 years of age) are often protected from pillaging and looting through national laws protecting cultural heritage. Internationally they may be protected by a State ratifying the Unesco Convention on the Protection of the Underwater Cultural Heritage . In this case pillaging is not allowed. One such example
5032-413: The wreck. On the seabed, wrecks are slowly broken up by the forces of wave action caused by the weather and currents caused by tides . Also, more highly oxygenated water, which promotes corrosion , reduces the strength of ferrous structural materials of the ship. Deeper wrecks are likely to be protected by less exposure to water movement and by lower levels of oxygen in water. Extreme cold (such as in

Submarines tend to last longer as they are built much more strongly to withstand the working loads of external pressure, and may last for centuries. A shipwreck may have value in several forms: Often, attempts are made to salvage shipwrecks, particularly those recently wrecked, to recover
5180-465: Was a significant degree of standardisation in some variants; the wine amphora held a standard measure of about 39 litres (41 US qt), giving rise to the amphora quadrantal as a unit of measure in the Roman Empire. In all, approximately 66 distinct types of amphora have been identified. Further, the term also stands for an ancient Roman unit of measurement for liquids. The volume of a Roman amphora
