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 Akko 1 Shipwreck, Israel: the First Two Seasons

The Akko 1 shipwreck was found in 4 m of water inside the ancient harbour of Akko (Acre), 250 m from the ancient wall, with its stern touching a submerged rampart. The dense framing-pattern and relatively thin planking, the extensive use of oak and the origin of the timber, suggest that this is the remains of a small armed ship or auxiliary vessel built in the Eastern Mediterranean. The ship has been provisionally dated to the late-18th or early-19th century, the late Ottoman period. The finds testify to its involvement in one of the naval campaigns at Akko.

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.     

New insights regarding the Akko 1 shipwreck: a metallurgic and petrographic investigation of the cannonballs

The Akko 1 shipwreck constitutes the remains of a small Mediterranean naval vessel, discovered in Akko harbour, Israel, and excavated over three seasons between 2006 and 2008. Among the finds at the shipwreck site were eleven cannonballs. Two of them, a 9-pdr and a 24-pdr, were retrieved and studied using metallurgical and petrographic methods. The examination of the cast-iron was performed with optical microscopy, SEM–EDS, XRF and microhardness tests. The remains of the casting sand from within the voids in both cannonballs were studied by petrography. Combined with the archaeological evidence and the historical background, the metallurgical and petrographic testing may suggest that Akko 1 was a warship or an auxiliary naval vessel of similar size to, or slightly smaller than, sixth rate, and was in Akko harbour circa 1840.     

Akko 1 shipwreck: the effect of cannon fire on the wooden hull

The Akko 1 shipwreck was discovered inside the harbour of the old walled city of Akko (Acre, St. Jean d'Acre, Akka), Israel. The ship's hull was built mainly of oak, with closely-set framing timbers that created a solid side. The shipwreck was apparently a result of the naval bombardment of the town in 1840.     

The 19th‐Century Akko Tower Wreck,Israel: a summary of the first two excavation seasons

The shipwreck designated as the Akko Tower Wreck lies at the entrance of Akko harbour, Israel, 35 m north of the Tower of Flies, in 4.4 m of water. Following two seasons (2012 and 2013) of underwater excavation, it is suggested that it is the remains of a merchant brig of 200 tons, dated to the first half of the 19th century, and built under the influence of the French shipbuilding tradition in an established shipyard. The full story of the ship and its place in the maritime history of Akko, however, remains an enigma.     

The Mazarrón 1 Shipwreck: an iron‐age boat with unique features from the Iberian Peninsula

Two iron‐age shipwrecks, associated with Phoenician ceramics, were discovered at the Playa de la Isla in Mazarrón, Spain. This preliminary report describes hitherto unknown boatbuilding features of the Mazarrón 1 hull remains. The vessel presents hybrid boatbuilding techniques using both pegged mortise‐and‐tenon plank‐edge fasteners and sewn seams employing longitudinal continuous stitching, and a unique keel scarf. It is an important source of information for the development of shipbuilding in the western Mediterranean during the Iron Age.     

More than Meets the Eye: A Preliminary Report on Artifacts from the Sediment of Site 31CR314, Queen Anne's Revenge,An Eighteenth-century Shipwreck Off Beaufort Inlet,North Carolina

The excavation of 31CR314, an eighteenth-century shipwreck identified by the North Carolina Department of Cultural Resources as Queen Anne's Revenge, off Beaufort, North Carolina, produced innumerable small artifacts from the sediment. In addition to objects of metal, glass, lithics, wood, and bone, thousands of microartifacts were recovered from the dredge spoil using a sluice and screen system. These microartifacts provide another layer of evidence, corroborating the current hypotheses regarding site formation processes, namely that the site represents a grounded vessel exposed to repeated periods of scour and reburial over nearly 300 years. The evidence provides a model for the formation of shipwreck sites in similar dynamic sand bar environments, where such sites would be exposed to the filtering of light artifacts, and the potential downward migration of artifacts into the substrate. Work at the site has shown that the extricating microartifacts from the sediment, although time-consuming, can make a significant contribution to understanding site formation processes.     

The Norman's Bay Shipwreck,East Sussex,UK: a possible 17th‐century Dutch ship from the Battle of Beachy Head

This report explores a hypothesis that the Norman's Bay shipwreck is the Wapen van Utrecht, a 64‐gun Dutch ship lost during the Battle of Beachy Head in 1690. The shipwreck, found off the Sussex coast, was designated by the Protection of Wrecks Act (1973) in 2006, when it was speculated that the wreck was the English 70‐gun ship Resolution, lost in the Great Storm of 1703. Dendrochronology dates the vessel after the middle of the 17th century AD, however, with timbers from Germany or the Low Countries. Initiatives by the Nautical Archaeology Society to bring the protected wreck to a wide public are also discussed.     

Neutron Activation Analysis of Late Sixth Century bce Pottery from the Pointe Lequin 1A Shipwreck and Massalia,and Comparison with the Cala Sant Vicenç Shipwreck and Emporion

This paper presents the results of neutron activation analyses of pottery samples from four late sixth century bce sites in the Western Mediterranean: the Pointe Lequin 1A shipwreck, the Bourse site in Marseilles, the Greek colony of Emporion and the Cala Sant Vicenç shipwreck, with the goal of locating the production of a commonly found cup type, the so‐called ‘Ionian’ cup, type B2. The NAA results show three distinct compositional groups, although the location of production could not be determined with certainty. The results also show that submarine diagenesis of pottery samples does not necessarily render them incomparable with samples from terrestrial sites.     

The connectivity of pore space in mudstones: insights from high‐pressure Wood's metal injection,BIB‐SEM imaging,and mercury intrusion porosimetry

Study of the pore space in mudstones by mercury intrusion porosimetry is a common but indirect technique and it is not clear which part of the pore space is actually filled with mercury. We studied samples from the Opalinus Clay, Boom Clay, Haynesville Shale, and Bossier Shale Formations using Wood's metal injection at 316 MPa, followed by novel ion beam polishing and high‐resolution scanning electron microscopy. This method allowed us to analyze at high resolution which parts of a rock are intruded by the liquid alloy at mm to cm scale. Results from the Opalinus Clay and Haynesville Shale show Wood's Metal in cracks, but the majority of the pore space is not filled although mercury intrusion data suggests that this is the case. In the silt‐rich Boom Clay sample, the majority of the pore space was filled Wood's metal, with unfilled islands of smaller pores. Bossier Shale shows heterogeneous impregnation with local filling of pores as small as 10 nm. We infer that mercury intrusion data from these samples is partly due to crack filling and compression of the sample. This compaction is caused by effective stress developed by mercury pressure and capillary resistance; it can close small pore throats, prevent injection of the liquid metal, and indicate an apparent porosity. Our results suggest that many published MIP data on mudstones could contain serious artifacts and reliable metal intrusion porosimetry requires a demonstration that the metal has entered the pores, for example by Wood's metal injection, broad ion beam polishing, and scanning electron microscopy.     

A Palaeodietary Study of Stable Isotope Analysis from a High‐status Burial in the Copper Age: The Montelirio Megalithic Structure at Valencina de la Concepción–Castilleja de Guzmán,Spain

This palaeodietary study presents carbon and nitrogen stable isotope data from human and faunal skeletal remains from the Copper Age settlement of Valencina de la Concepción–Castilleja de Guzmán, located in Seville, Spain. Montelirio, the only Valencina–Castilleja human group from which we have obtained reliable palaeodietary results, had a diet based on C₃ terrestrial resources, including both plants and animals. The protein component of the diet consisted mainly of meat, milk and dairy products from livestock as well as C₃ plant protein from cereals and pulses. This study compares data from Montelirio, the Copper Age group from Valencina–Castilleja, with the published data from other Iberian Late Neolithic–Copper Age (LN‐CA) societies. This comparison reveals a homogeneous diet with some exceptions. Overall, the LN‐CA diet in the Iberian Peninsula consisted mainly of animal proteins from meat, milk and dairy products from livestock as well as C₃ plant sources from the characteristic agriculture of the societies of these periods. This study also demonstrates the minor use of aquatic resources from the Neolithic to the Copper Age period in the Iberian Peninsula. Copyright © 2015 John Wiley & Sons, Ltd.
