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.     

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.     

First record of the trace fossil Protovirgularia from the Middle Permian of southeastern Gondwana (southern Sydney Basin,Australia)

LUO, M. &; SHI G.R., February 2017. First record of the trace fossil Protovirgularia from the Middle Permian of southeastern Gondwana (southern Sydney Basin, Australia). Alcheringa 0, 000–000. ISSN 0311-5518.

This study reports the first examples of well-preserved chevronate trails referable to Protovirgularia longespicata De Stefani, 1885 Stefani, DE.C., 1885. Studi paleozoologici sulle creta superiore e media dell' Apennino settentionale. Atti della Reale Accademia dea Lincei, Memorie 22, 101?134. [Google Scholar] from the early Middle Permian (Roadian) upper Wandrawandian Siltstone of the southern Sydney Basin, southeastern Australia. The highly meandering trace with closely spaced, papillate chevrons is interpreted to have been produced by the locomotion-feeding behaviour of certain protobranch bivalves in an offshore environment. The dense trails occurring on the upper bedding planes of pebbly siltstone may represent a gregarious lifestyle, where junior and senior individuals of the trace-maker bivalves coexisted while moving within sediments. The Wandrawandian Protovirgularia also represents the first known occurrence of this ichnotaxon from a glaciomarine environment in the Permian eastern Gondwana. The global record of Protovirgularia occurrences suggests that these trails had a wide environmental distribution since the Cambrian, and there is no obvious difference in the environmental distribution of Protovirgularia after the Permian?Triassic transition.

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 Sydney 2000 Olympics and Urban Entrepreneurialism: Local Variations in Urban Governance

Hallmark events are important redevelopment tools utilised by entrepreneurial governments. The features of these events are analogous to those of entrepreneurial urban governance. This study examined the local impacts of the Sydney 2000 Olympic Games, particularly in relation to its social and political legacies, in three local government areas which hosted Olympic venues. It also investigated the nature of urban governance in Sydney, Australia, as it was manifested in the planning of the Sydney 2000 Olympics. Examples of entrepreneurialism in planning for the Olympics included the centralisation of planning powers, the increasing involvement of the private sector in government activities, and the relaxation of planning processes, resulting in reduced openness, accountability and public participation. Examples of resistance to the anti–democratic tendencies of entrepreneurialism were however evident in some areas, with managerial and democratic concerns remaining important to some local governments. Local community activism was imperative to achieving civic participation and ensuring commitment by local government to these managerial and democratic concerns. Activism also enabled some local communities to secure significant benefits from the Olympic Games.     

Desocializing space: the decline of the public realm in Western Sydney1

This paper addresses the public realm and considers its contemporary context in an important Australian region, Western Sydney. Although problematized by social theory in recent years, my base position is the Habermasian premise that a public realm is critical to the healthy functioning of liberal democracies, such as Australia. This paper has three specific aims. First, I note the erosion of the public realm in an important Australian region, Western Sydney, and the obfuscation of its presence and role by new institutional arrangements emerging principally but not exclusively from federal policy settings. I then consider the consequences of this ‘desocialization of space’ for democracy and equity in a socially and culturally diverse urban region such as Western Sydney.

Désocialiser l'espace: le déclin de la sphère publique dans le Western Sydney

espace public, Western Sydney, néolibéralisme

Le présent article s'intéresse à la question de la sphère publique et examine sa condition actuelle à Western Sydney, une région australienne d'une importance capitale. Bien que la théorie sociale l'a récemment remise en cause, je m'appuie sur la prémisse d'Habermas selon laquelle la sphère publique est essentielle pour le bon fonctionnement des démocraties libérales comme celle qui prévaut en Australie. Les trois principaux buts de cet article sont de faire état de l'érosion de la sphère publique dans une des plus importantes régions australiennes qu'est Western Sydney. Je souligne à quel point sa présence et son rôle sont embrouillés par de nouveaux arrangements institutionnels qui naissent surtout mais pas uniquement grâce aux instances politiques fédérales. J'aborde ensuite les conséquences qu'entraînent la «désocialisation de l'espace» pour la démocratie et l'équité dans la vaste mosaïque socioculturelle urbaine de Western Sydney.

La desocialización del espacio: la disminución del terreno público en el oeste de Sydney

espacio público, el oeste de Sydney, el neo-liberalismo

Este papel trata el terreno público y considera su contexto contemporáneo en una región importante de Australia, el oeste de Sydney. Aunque la teoría social lo ha problematizado en recientes años, yo me baso en la premisa de Habermas de que un terreno público es esencial al buen funcionamiento de las democracias liberales, como la de Australia. Este papel tiene tres objetivos específicos. Primero, hablo de la erosión del terreno público en una región importante de Australia, el oeste de Sydney, y de la ofuscación de su presencia y de su papel, causada por nuevos arreglos institucionales que han surgido principalmente, pero no exclusivamente, de la política federal. Luego, considero las consecuencias para la democracia y la igualdad de esta ‘desocialización de espacio’ en una región urbana donde hay gran diversidad cultural y social, como el oeste de Sydney.     

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.     

False,cheap and degraded: when history,economy and environment collided at Cades Cove,Great Smoky Mountains National Park

Great Smoky Mountains National Park was created in 1934 after decades of popular activism. The National Park Service initially planned to restore wildness to all formerly settled lands through the process of secondary succession, but did not in a valley in the northwest corner of the park, Cades Cove. Transforming the 1200-ha agricultural setting into forest would have eliminated the visual charm highly prized by the tourists who had long come there. Additionally, experts promoted the preservation of Cades Cove's historic–cultural landscape because they falsely perceived the local culture to be a relic of the past. The Park Service acceded, but its commitment to historic preservation was tempered by a concern to minimize its expenses. Consequently, an agricultural permit system was adopted in 1945, which allowed modern farmers to operate on the historic landscape, keeping it open. This cheap method kept open the beautiful vistas of Cades Cove. Unfortunately, the agency's commitment to beauty and economy led to decades of ecological degradation, including water pollution and species extirpation. Only in the last two decades, has park management moved away from its focus on a low-cost, attractive landscape to embrace one that is also ecologically healthy, and thus more sustainable.     

A new Triassic Palaeolimnadiopsis (Crustacea: Conchostraca) from the Sydney Basin,New South Wales

Palaeolimnadiopsis bassi sp. nov. is described from the mid-Triassic Hawkesbury Sandstone of the Sydney Basin, New South Wales. It is distinguished from other species of the genus by its paired growth lines, moderately large size, nonterminal umbo, and small larval valve. Macrolimnadiopsis, Pteriograpta, and Limnadia (Falsisca) are considered to be synonymous with Palaeolimnadiopsis, and Belgolimnadiopsis with Euestheria.     

Early Cretaceous polar biotas of Victoria,southeastern Australia—an overview of research to date

Poropat, S.F., Martin, S.K., Tosolini, A.-M.P., Wagstaff, B.E, Bean, L.B., Kear, B.P., Vickers-Rich, P. &; Rich, T.H., May 2018. Early Cretaceous polar biotas of Victoria, southeastern Australia—an overview of research to date. Alcheringa 42, 158–230. ISSN 0311-5518.

Although Cretaceous fossils (coal excluded) from Victoria, Australia, were first reported in the 1850s, it was not until the 1950s that detailed studies of these fossils were undertaken. Numerous fossil localities have been identified in Victoria since the 1960s, including the Koonwarra Fossil Bed (Strzelecki Group) near Leongatha, the Dinosaur Cove and Eric the Red West sites (Otway Group) at Cape Otway, and the Flat Rocks site (Strzelecki Group) near Cape Paterson. Systematic exploration over the past five decades has resulted in the collection of thousands of fossils representing various plants, invertebrates and vertebrates. Some of the best-preserved and most diverse Hauterivian–Barremian floral assemblages in Australia derive from outcrops of the lower Strzelecki Group in the Gippsland Basin. The slightly younger Koonwarra Fossil Bed (Aptian) is a Konservat-Lagerstätte that also preserves abundant plants, including one of the oldest known flowers. In addition, insects, crustaceans (including the only syncaridans known from Australia between the Triassic and the present), arachnids (including Australia’s only known opilione), the stratigraphically youngest xiphosurans from Australia, bryozoans, unionoid molluscs and a rich assemblage of actinopterygian fish are known from the Koonwarra Fossil Bed. The oldest known—and only Mesozoic—fossil feathers from the Australian continent constitute the only evidence for tetrapods at Koonwarra. By contrast, the Barremian–Aptian-aged deposits at the Flat Rocks site, and the Aptian–Albian-aged strata at the Dinosaur Cove and Eric the Red West sites, are all dominated by tetrapod fossils, with actinopterygians and dipnoans relatively rare. Small ornithopod (=basal neornithischian) dinosaurs are numerically common, known from four partial skeletons and a multitude of isolated bones. Aquatic meiolaniform turtles constitute another prominent faunal element, represented by numerous isolated bones and articulated carapaces and plastrons. More than 50 specimens—mostly lower jaws—evince a high diversity of mammals, including monotremes, a multituberculate and several enigmatic ausktribosphenids. Relatively minor components of these fossil assemblages are diverse theropods (including birds), rare ankylosaurs and ceratopsians, pterosaurs, non-marine plesiosaurs and a lepidosaur. In the older strata of the upper Strzelecki Group, temnospondyl amphibians—the youngest known worldwide—are a conspicuous component of the fauna, whereas crocodylomorphs appear to be present only in up-sequence deposits of the Otway Group. Invertebrates are uncommon, although decapod crustaceans and unionoid bivalves have been described. Collectively, the Early Cretaceous biota of Victoria provides insights into a unique Mesozoic high-latitude palaeoenvironment and elucidates both palaeoclimatic and palaeobiogeographic changes throughout more than 25 million years of geological time.

Maʻagan Mikhael B,Israel: a preliminary report of a Late Byzantine–Early Islamic period shipwreck

The Ma?agan Mikhael B shipwreck was found in 1.5m of water, beneath 1.5m of sand, 70m off the Mediterranean coast of Israel. The hull remains are in a good state of preservation, comprising the endposts, aprons, framing timbers, hull planks, stringers, and bulkheads. The finds comprise rigging elements, wooden artefacts, organic finds, animal bones, glassware, coins, bricks, stones, ceramic sherds, and complete amphoras. The shipwreck was dated to the 7th–8th centuries AD; which makes it an exceptional source of information regarding various aspects of ship construction, seamanship, and seafaring in the area in Late Antiquity.     

Managing ‘Aboriginal selves’ in South‐Western Sydney1

ABSTRACT This paper explores Aboriginal people's multiple sense of selves in suburban situations. While the Aboriginal self has been usually conceived as forged through relationships with kin, in the contemporary world, Aboriginal lives are constrained by a genealogical understanding of Aboriginality, that is, one based on descent. This understanding is endorsed by the state system, by Aboriginal and non‐Aboriginal organisations, and by non‐Aboriginal people. In the suburbs there are different ways in which people come to understand and identify their Aboriginalty. Drawing on ethnographic field‐work in south‐west Sydney, this paper explores these forms of identity, how they are perceived, and the effects this has on their sense of self. The focus is on two individuals with different backgrounds and understandings of what it is to be Aboriginal. The increasing role of Aboriginal organisations to offer new forms of relatedness is also discussed.     

From icons to institutions: Heritage conservation in Sydney

Over the course of the twentieth century, the Identification of heritage values in the urban environment has undergone a slow but in recent years quite dramatic shift from an elite emphasis on individual landmarks to a more inclusive appreciation also characterised by bureaucratisation, institutionalisation and commodification. Heritage is no longer an ‘add on’ to the planning system, although management, financial and philosophical problems remain. This paper traces the evolution of urban heritage consciousness and policy in Australia from the late colonial period to the postmodern era, focussing on Sydney.     

Who were bennelong and Pemulwuy? Museums in Sydney and interpretation of eora aboriginal culture

Abstract

The Eora Aboriginal People are the original inhabitants of the Sydney region [in NSW, Australia]. There are an estimated 2, 000 Aboriginal rock engravings in Sydney. Some museums in Sydney now acknowledge the traditional Aboriginal owners and use Eora words to name their exhibitions. These include: Ngaramang bayumi – music & dance (Powerhouse Museum); Merana Eora Nora – first people (Australian National Maritime Museum); Yiribana (Art Gallery of New South Wales); and Cadi Eora Birrung: Under the Sydney Stars (Sydney Observatory). The Aboriginal history of Sydney, however, is only told at the Museum of Sydney with installations, videos and spoken exhibits about Eora, the indigenous peoples of Sydney. This paper reviews the Eora Aboriginal exhibits at the Museum of Sydney. It questions whether visitors to Sydney learn about Bennelong and Pemulwuy, two key Aboriginal figures in the the early European settlement around Sydney Harbour. Sydney Aboriginal Discoveries on their Dreamtime cruise of Sydney Harbour provide another interpretation of Eora history and culture. The paper suggests the Eora heritage of Sydney should be more widely interpreted in Museums, National Parks and other public venues to rightfully acknowledge this Aboriginal history.     

Exploration of Basel Mission Company shipwreck remains at St George's Reef off Goa, West Coast of India: impact of the Basel Mission Co. on society and culture

A systematic exploration of shipwrecks has been carried out in Goa waters since 1997. Exploration off St George's Reef has brought to light the remains of a shipwreck at a depth of 15 m, containing various types of terracotta artefacts intended for house construction. Basel Mission Tile Works 1865' is impressed on bricks, roof and floor tiles. Study shows that the company was active in manufacturing terracotta and exported it to Africa, Australia, Borneo, Sumatra, and other countries. It has been renamed 'Comtrust', and is still producing terracotta using the same techniques. The impact of the Basel Mission Co. on society and culture is discussed. A study of finds of wrecks in the Mangalore and Calicut areas was undertaken.     

Kinship,Organisations and ‘wannabes’: Aboriginal Identity Negotiation in South‐western Sydney

ABSTRACT This paper explores the ambiguous and dynamic nature of Aboriginal identity in south‐western Sydney. While for most of the Aboriginal people in rural and remote areas, identity has been primarily a matter of kinship ties associated with their perceived place of origin, Aboriginal people often recognize each other as Aboriginal by sharing and recognizing certain ‘Aboriginal’ cultural mores and traits. These two principles of identity are flexible enough to be extended to those who are not raised in an Aboriginal family environment; one meeting with their Aboriginal family is a minimum requirement. In south‐western Sydney, where organizations dealing with Aboriginal issues provide ways of connecting Aboriginal people from various backgrounds, in line with the government's homogenized notion of Aboriginality, Aboriginal people from Aboriginal family environments encounter those who cannot even meet this compromised criterion. Their presence gives rise to tension and conflict revolving around the concept of Aboriginality. Aboriginal cultural values that emphasize actual engagement provide ways of overcoming such dilemmas. Through common participation in the activities of the aforesaid organisations, Aboriginal people in south‐western Sydney develop a new sense of ‘Aboriginality’, which embraces those who cannot claim kinship ties.
