Lead ingots from a shipwreck Off Poompuhar, Tamil Nadu, East Coast of India: evidence for overseas trade and their significance

Various types of lead ingots have been reported from a number of shipwrecks from different parts of the world. In 1991 exploration of a wreck off Poompuhar, Tamil Nadu, East Coast of India, at a depth of 19 m yielded a gun, rudder gudgeon, gunpowder boxes and a variety of lead ingots. The most significant ingots are those marked W: Blackett and D with a crown symbol on the obverse and 1791, 1792 and some merchant marks on the reverse. These are similar to Blackett lead ingots found in England, the Netherlands and Sumatra. Pb-isotopic analysis has revealed their source as the North Pennine lead mines of England. Further, the lead used was of high purity -93%. Records show that Blackett was a well-known lead-exporting company in England since 1694. The wreck off Poompuhar may be a Toni type cargo ship carrying traded lead ingots of different manufacturers.     

The Levanzo I Wreck,Sicily: a 4th‐century AD merchantman in the service of the annona?

Between 2005 and 2009 a deep‐water shipwreck was located, mapped, and partially excavated by a joint team from RPM Nautical Foundation and the office of the Soprintendenza del Mare, Sicily. Located off Levanzo Island, one of the Egadi Islands off north‐west Sicily, this wrecked merchantman revealed a mixed cargo of foodstuffs, coarseware, glass, and construction materials. The nature of the wreck‐site, its cargo, operational date, and find‐location indicate its likely association with the annona service which supplied Rome. © 2012 The Authors     

New Evidence for the Submerged Ancient Harbour Structures at Tolmetha and Leptis Magna,Libya

Surveys carried out in 2009, during a project for the creation of three underwater archaeological parks in Libya, have allowed archaeologists both to analyse already known ancient structures and to discover new evidence about the harbour areas of the ancient cities of Tolmetha and Leptis Magna. © 2012 The Author     

The 4th-century B.C. shipwreck at Mazotos,Cyprus: New techniques and methodologies in the 3D mapping of shipwreck excavations

Abstract

Well preserved ancient shipwrecks are rare in the archaeological record, but when discovered, they can provide valuable information on a wide range of research issues if analyzed and documented properly. In this paper we discuss the significance, potential, and constraints of mapping methods applied during the underwater excavation of shipwreck sites with special emphasis on stratigraphy, documentation of finds, and reconstruction of site formation processes. As a case study, we present the digital photogrammetry and computer vision software programs used in the excavation of the 4th-century b.c. shipwreck at Mazotos, Cyprus. Our goal is to develop a targeted documentation and mapping method of ongoing shipwreck excavations so that others can address complex research questions concerning this unique discipline of archaeology.     

The 19th‐Century Akko 1 Shipwreck,Israel: hull‐construction report

The Akko 1 shipwreck was found in 4 m of water inside the ancient harbour of Akko, Israel, and was fully recorded under water. Several hull‐components were retrieved and documented on land, as well as all the finds. The results of the archaeological research and the study of the historical background suggest that the Akko 1 shipwreck is the remains of an eastern Mediterranean naval auxiliary brig, built at the end of the first quarter of the 19th century, and sailing under the Egyptian flag. The ship was apparently wrecked during the 1840 naval bombardment of Akko. © 2012 The Authors     

The Roman Shipwreck of Antirhodos Island in the Portus Magnus of Alexandria,Egypt

Between 1998 and 1999 three excavation campaigns were undertaken on a shipwreck at the now‐submerged site of the ancient Portus Magnus, off the coast of Alexandria. The site, close to the island of Antirhodos, was identified through geophysical and archaeological surveys carried out by the Institut Européen d’Archéologie Sous‐Marine (IEASM), directed by Franck Goddio. The remains of the ship lie c.5 m deep and are spread over c.350 sqm. No cargo has been found. Artefacts recovered, the details of the ship's architecture and radiocarbon dating all suggest it sunk between the end of the 1st century BCE and the 1st century CE. Its dimensions correspond to those of commercial ships of the Roman era. Identification of the wood used contributes significantly to our knowledge of materials used in naval architecture of this period.     

The Byzantine‐Period Dor 2006 Shipwreck,Israel: preliminary hull construction report

The Dor 2006 shipwreck was discovered in 2006, 100 m offshore, 800 m south of Dor (Tantura) lagoon. The wooden hull remains included sections of large frames, stringers and ceiling planks, a large number of strakes and wales, some with unpegged mortise‐and‐tenon joints. Among the finds were ceramic sherds, wooden objects, matting, ropes, food remains, and coins. The shipwreck was dated to between the second half of the 6th and the first quarter of the 7th centuries AD. The wooden components of the hull indicate a large ship compared with other shipwrecks of the period, and the largest ever excavated in the Dor area.     

A Critical Analysis and Philosophical Review of ‘Rapid Reburial’: the Clarence project

In 2012, Australian cultural heritage practitioners and conservation scientists collaborated on a national underwater cultural heritage (UCH) reburial project, known as the Australian Historic Shipwreck Preservation Project (AHSPP) funded by the Australian Research Council. This resulted in the excavation, documentation and reburial of the ‘at risk’ shipwreck Clarence. Following the excavation, the site and associated artefacts were reburied and subsequently covered by shade cloth and finally, with polyvinyl chloride (PVC) tarpaulins. After completion of the in situ reburial, a number of critical issues were put into sharp relief including: what constitutes the accurate identification of a site as being ‘at risk’; and the implications of ‘rapid reburial’.     

Florida's Mystery Wreck

During the summer of 2005 the Florida Bureau of Archaeological Research and the Florida Keys National Marine Sanctuary investigated an unusual shipwreck in 6 m (20 ft) of water off Marathon in the Florida Keys. Known locally as the 'Mystery Wreck' it remained relatively undisturbed for over two decades until State of Florida and Sanctuary archaeologists conducted a research project to learn more about this fascinating early shipwreck. This paper presents a summary of field investigations and a preliminary interpretation of the shipwreck.

A Colonial Shipwreck in Saipan,Northern Mariana Islands

Previous underwater cultural heritage investigations conducted in the western Pacific's Northern Mariana Islands largely focused on the submerged World War Two remains, despite the islands’ rich colonial history. The island chain was the setting of numerous historical occupations including indigenous Chamorro populations, Spain, Germany, Japan and the United States, all of which created a lasting maritime heritage legacy on land and under water. This paper presents the first colonial shipwreck investigation to be undertaken by archaeologists and fills a gap in our history and knowledge of the Mariana Islands’ pre‐World War Two era.
