Archaeometallurgical study of the brass cases from the Akko 1 shipwreck

The Akko 1 shipwreck is the remains of an eastern Mediterranean brig built in the first quarter of the nineteenth century, discovered in Akko harbour, Israel. During the underwater excavations (2006–2008), 158 brass cases were found, mainly between midships and the aft extremity of the shipwreck. It is suggested that they were used for artillery quills. The aim of this investigation is to determine the composition, microstructure and properties of these brass cases in order to understand their manufacturing process and to propose their possible dating and manufacturing location, and to verify their use. An archaeometallurgical analysis of selected brass cases was performed, including optical microscopy, microhardness tests and SEM including EDS. The results show that the collection was made of brass containing about 30 wt% zinc. The uniform thickness and the microstructure of the cases indicate that all artifacts were basically produced of rolled sheets and the cases were hand-made using simple tools. The metallurgical investigation suggests that they were manufactured during the first half of the nineteenth century. Combined with the archaeological evidence and the historical background, this supports the assumption that Akko 1 was a naval auxiliary vessel which was in Akko harbour circa 1840.     

Modeling distance with time in ancient Mediterranean seafaring: a GIS application for the interpretation of maritime connectivity

Investigations of Mediterranean connectivity have increasingly turned toward maritime landscape models to frame questions of seaborne exploration, marine resource exploitation, trade and exchange, and seafaring culture. Environmental and technological parameters are consistently acknowledged as crucial for understanding when and why different relationships developed across the sea, but their formal employment in the modeling and interpretation of maritime space remains quite limited. The methodology outlined here utilizes Geographic Information Systems (GIS) to integrate environment and technology as analytical tools for exploring the complexity of seaborne connectivity. Focusing on sailing days as practical units of distance and using an Archaic Greek shipwreck off Turkey as a case study, this preliminary model demonstrates how a more nuanced spatial approach can inform the human geography and socioeconomic structures of ancient maritime interaction.     

Showcasing Maritime Heritage Artefacts for the Benefit of the Tourist Industry in Malaysia

Conservation in urban areas is an active issue, but in remoter areas historical remains are neglected by both public and government. Conservation of maritime archaeological sites is fast becoming important elsewhere. Acknowledging the importance of conservation for other types of historical sites, this paper addresses the need for conservation of the as-yet-unknown number of maritime archaeological sites in Malaysia. This will take time and continuing effort. Malacca Maritime Museum is a case-study, built specifically for showcasing artefacts from shipwrecks. The first such museum in Malaysia, it has benefited tourism as well as preserving objects and educating the public.

The Phinney Site: The Remains of an American Armed Vessel Scuttled During the Penobscot Expedition of 1779

During the autumn of 1999 and 2000, members of the US Naval Historical Center's Underwater Archaeology Branch conducted an archaeological investigation of a wooden-hulled shipwreck in the Penobscot River, Penobscot County, Maine. The shipwreck site, known locally as the 'Phinney Site', represents a middle-to-late 18th century vessel. Attributes of the vessel's construction and artefact assemblage indicate that it was American-built, owned, and operated. Data recovered during the excavations have established an association between the shipwreck and the 1779 American fleet of nine armed ships scuttled in the river near the present-day city of Bangor during the final days of the Penobscot Expedition.

The Sydney Cove shipwreck project

Lost in 1797 during a voyage from India to Australia, the wreck of the merchant ship Sydney Cove was rediscovered in 1977. A project to excavate and present material from the site was carried out by the designated management agency during the 1990s. The work has provided a unique insight into the merchant ships and cargoes that were vital to the early development of the Australian colonies. This paper presents a summary of the project upon its completion in 2001.     

Description and Analysis of the Finds from the 2006 Turkish Coastal Survey: Marmaris and Bodrum

In the summer of 2006, RPM Nautical Foundation continued its survey along the south-western Turkish coast. After completing the verification of anomalies along the south-east Bozburun peninsula close to Marmaris, a new survey was conducted along the coast near Bodrum. Additional shipwrecks were discovered, those of historic interest ranging in date from Roman Republican to Ottoman. This report describes the shipwreck sites and some of the random finds along the Bozburun coast, as well as the depositional characteristics in the Bodrum approaches.

Preliminary Analysis of the Hull of the Roman Ship from Grado, Gorizia, Italy

The hull of the Roman wreck at Grado has been partially preserved under the cargo of amphoras. The right side presents a rare evidence of a section of the waterway. The ship has been assembled by mortise-and-tenon technique following a shell-first conception. All the frames, except one, are of pine while planking is either of pine and elm. Some strakes, of larix , are a repair made by patch-tenons; a wale shows an other kind of repair. Various signs left by the shipwright are on the hull. In the stern area, a box of wooden elements had to protect a 'hydraulic system'.

Iconic Arctic Shipwrecks,Archaeology, and Museum Narratives

This article reflects on three Arctic shipwrecks currently being reclaimed for future exhibition. Two are icons of polar exploration. Maud was built for Roald Amundsen's North Pole expedition (1917–1925) and Belgica was used in the first Antarctic overwintering expedition (1897–1899). The salvage of Maud in Canada and the ship's return to Norway in 2018 was privately financed. Raising Belgica has been the goal of a Belgian non‐profit organization. The third is a medieval Norwegian wreck excavated in 2017 with community funding. The role of each ship as icon and archaeological heritage is assessed and framed within a broader discussion of museum narratives.     

The Port‐Vendres 4 Shipwreck Cargo: evidence of the Roman wine trade in the western Mediterranean

The Port‐Vendres 4 shipwreck is evidence of coastal export trade between Hispania Citerior and Narbonne in 40/30 BC. The cargo is made up of a particular assemblage of Roman wine amphoras (Pascual 1, Dressel 1B and Lamboglia 2) destined for Gallic markets. Archaeological and archaeometric analyses conducted on a selection of the amphoras allowed the provenance of the cargo to be identified as Hispania Citerior and the central‐southern Tyrrhenian coast of Italy. Iluro and/or Baetulo are proposed as the ports of departure, enabling the reconstruction of the trade route and the historical and economic significance of this shipwreck.     

慈溪潮塘江元代沉船保存状态研究

慈溪潮塘江元代沉船是慈溪地区迄今发现并经科学发掘的第一艘古代沉船,船体结构保存较为完整,现存10道隔舱壁板。通过¹⁴C测年进一步确认沉船所属时代为元代(1271年—1368年)。在沉船船体70个监测点位采集样品,从树种类型、木材化学组分、硫铁元素含量以及微生物病害种类等多个角度开展检测研究,全面调查分析沉船病害情况。结果表明,慈溪潮塘江元代沉船木材样品整体保存状态较好,由于长期处于内河道埋藏环境,木材处于饱水状态,最大含水率主要集中分布于185%～400%之间,局部区域呈现变色、变形、扭曲、开裂现象,木材化学组分呈现低综纤维素、高灰分的特点,含有少量硫铁元素,属于中度腐蚀状态,亟待开展盐分脱除与填充加固等船体保护工作。
