A combination of reconstruction of the former coastline and field survey of previously unrecorded sites provides the basis for the study of the maritime landscape and maritime activities around Portrush on the north coast of Ireland during the Mesolithic period. Movements in relative sea‐level and geological events indicate significant change in environment and availability of resources, particularly flint, for the coastal community. Evidence suggests that most Early Mesolithic material, deposited close to the then shoreline, is presently under water. Remnants of the Late Mesolithic are fast disappearing as coastal erosion continues. © 2010 The Author  相似文献

This paper reports on the first systematic attempt to conduct archaeological survey and excavation for submerged prehistory on the island of Ireland. Fieldwork was conducted in two small bays where Early Mesolithic flint artefacts washed ashore hinted at the presence of a submerged assemblage. Methods employed include non‐intrusive survey, hand coring and excavation. Together, these allowed identification of the artefact source, albeit reworked, in one bay and an early Holocene peat in the other. Though the subtidal assemblage is reworked and relatively small, it is significant in an Irish context and more widely illustrates the potential preservation of prehistoric sites and palaeo‐landscapes in high‐energy settings.  相似文献

This paper describes Phase 1 of the project ‘Archaeological Applications of the Joint Irish Bathymetric Survey (JIBS) Data’, analysing bathymetric and backscatter data derived from multibeam surveys off the north coast of Ireland. In particular, the usability of the data for shipwreck detection, identification and site characterization is explored. In Phase 1, the data was screened for anomalous sea‐bed features, which were subsequently described, catalogued and categorized according to their archaeological potential and cross‐referenced against existing records. A planned second phase of this project will examine each anomaly in greater detail together with the local and regional hydrodynamic conditions. © 2010 The Authors  相似文献

The value of testate amoebae in the reconstruction of changes in surface wetness from ombrotrophic mires is well known, but the potential value of such records in specifically archaeological investigations has not yet been investigated. This note describes the analysis of testate amoebae for a sediment sequence from the multi-period wetland archaeological site of Derryville, Co. Tipperary, Ireland. The reconstructed watertable is presented and plotted against the range of dates from excavated archaeological features in the wetland area. The data demonstrate a clear association between periods of low watertable and increased anthropogenic activity as reflected by site construction. The value of testate amoebae in future integrated archaeological investigations of wetland systems is discussed.  相似文献

Sampling of archaeological human bone may not be justified, contrary to former high expectations regarding adult age assessment based on histomorphometry. The alterations in buried bone as a result of bacterial action are readily visible in the scanning electron microscope (SEM). An understanding of the chemical and structural changes to cortical bone requires work at the level of a few microns. This paper reports on problems encountered during analyses of samples of human bone from Mesolithic (ca. 8000 calbp) shell midden sites at Muge in central Portugal, and the methods used to try and overcome these problems. We believe we have shown that these Mesolithic bones are partly comprised of bacterially reprecipitated mineral, which has had collagen removed, with consequent obliteration of bone microstructure. We conclude that microbial destruction of the structure of archaeological bone can be a serious impediment to analysis of the characteristics of the population represented by those skeletal remains.

This reports on a project that combined evidence gleaned from aerial photographs, place‐names, interviews, topography, LIDAR data, and sonar bathymetry to locate stone tidal fish weirs in the Molène Archipelago. The results were verified by diver and pedestrian visual surveys. Models of Holocene sea‐level change allowed a group of possibly Late Mesolithic–Early Neolithic weirs to be recognized, with a second group broadly dated to the later Neolithic–Early Bronze Age. The construction of these long megalithic structures is compared to the funerary monuments for which the Molène Archipelago is well known, in terms of technique, cost, and societal organization.  相似文献

Utilizing a new theory for examining critical junctures, we seek to better understand the nature of industrial policy change in Ireland during the 1950s and macroeconomic policy change in Sweden in the 1980s. Did these policy changes constitute critical junctures, or something less, and if so why? The theory consists of three elements—economic crisis, ideational change, and the nature of the policy change—that must be identified for us to be able to declare with some certainty if a policy change constitutes a critical juncture. Herein, we will be examining the roles of a variety of change agents including the media, central banks, and politicians. Our findings will help explain why Irish industrial policy was transformed in the late 1950s, while Swedish macroeconomic policy underwent only minor change in the early 1980s.  相似文献

To explore the use of sulphur isotopes as an indicator of the consumption of freshwater fish, we undertook sulphur isotope analysis on bone collagen extracted from humans and animals from five archaeological sites from the Danube Gorges region dating from the Mesolithic to the middle Neolithic periods. The results show a difference in the sulphur isotope values between freshwater and terrestrial ecosystems of 8.7‰. To reconstruct human diets, bone collagen from 24 individuals was analysed for carbon, nitrogen and sulphur isotopic values. The nitrogen isotope ratios ranged from 10.3 to 16.5‰ and the carbon isotope ratios ranged from −20.8 to −18.3‰. Low nitrogen isotope values were found for individuals with low sulphur isotope ratios reflecting the low sulphur isotopic values of the terrestrial animals. The highest human nitrogen isotope values coincided with higher sulphur isotope ratios, which are related to the higher sulphur isotope values of the freshwater fish. Intermediate human sulphur isotopic ratios between these two extremes showed mixed diets of both terrestrial and freshwater resources.  相似文献

This article describes fieldwork undertaken in 1972 at the harbour of the Hellenistic city of Ptolemais at Tolmeita in Cyrenaica, Libya. This survey has shown that the city possessed a sophisticated Hellenistic harbour installation, now submerged by some 2 m. It consisted of a small fishing harbour and a larger commercial harbour protected by extensive stone breakwaters built around two offshore islands. Between the harbours, remains were found under water of an extensive block‐built quay connected to one island, where there was a system of submerged rock‐cut tanks. These are interpreted as the foundations of a fish‐processing factory. Changes in sea‐level are also discussed.  相似文献

We present and test a predictive archaeological survey model that targets early Holocene paleoshorelines in the Prince Rupert Harbour area using LiDAR bare earth digital terrain models and a 15,000-year reconstructed history of relative sea level change. Despite a century of archaeological research in the study area, no sites dating earlier than 6000 cal b.p. had been identified prior to our research. Our field survey identified three early Holocene sites associated with paleoshorelines 7–10?m above current sea level (masl). These locations demonstrate repeated use through the Holocene even as shoreline position changes. We discuss these new data in relation to the early Holocene archaeological record from the rest of the northern Northwest Coast and suggest that the region was ubiquitously occupied by this time and that the lack of recorded early Holocene sites in some areas is likely a result of survey and preservation bias, rather than historical reality.  相似文献

This paper investigates the paradox in post‐conflict societies of continued marginality of cross‐ethnic parties despite significant convergence in public attitudes and identities. In so doing, it examines the argument that parties that attempt to reach across the divide are constrained by consocational institutions designed to accommodate rival identities in such environments. The paper explores this puzzle in the context of Northern Ireland, drawing upon qualitative evidence from elite interviews and focus groups collected in 2012 and 2013. It concludes that cross‐community parties operating in the region do encounter formal institutional barriers, but that such barriers only partially explain the phenomenon and an interplay between formal and informal constraints underlies their position of relatively limited electoral success.  相似文献

This paper examines the theory and practice of the maritime cultural landscape in general, and projects the theoretical concepts and aspects involved on the highly dynamic late medieval north‐eastern Zuiderzee region in the Netherlands. The cultivation of land and marine erosion (floods and rising sea level) are considered as the main factors that caused the transformation of the physical landscape of this region from peatlands with freshwater basins into a tidal lagoon. As a consequence, multiple settlements drowned, large areas of land submerged, and culture and the landscape gradually became more maritime, giving the research area a cultural identity and dimension.  相似文献

Predictions of future requirements for the protection of maritime archaeological sites are made using the fetch method which has been developed to evaluate the quality of landing‐places and navigable channels. The very useful method may explain why archaeological sites along the coast are rare in some areas, but numerous in others. Many of them are vulnerable to destruction by the effects of climate change, especially rising sea‐levels, based on the IPCC scenarios. The objective fetch method can be used worldwide to predict where new finds of sites close to sea‐level can be expected, and also to predict a site's vulnerability.  相似文献

Important pressures still increase the vulnerability of peri‐urban farming despite initiatives to protect agricultural land and activities since the mid‐1960s in several jurisdictions in the USA and Canada. Often, farmland is still removed from agricultural reserves for the ‘good of society’ (for example, creating industrial parks). In 2008, an action research project was initiated to attempt to reduce agricultural vulnerability in several peri‐urban and rural areas near Montreal by emphasising the importance of the appropriation of the value of these farmlands by non‐farm citizens and actors. The action research roles involved accompanying the farmers, facilitating meetings, mobilising non‐farm actors, and informing farmers of possibilities when asked to do so. In this article, one specific project is analysed in Senneville (in the west of Montreal Island). While the project was initiated by the farmers to guarantee their long‐term future, they also sought to involve other, mostly non‐agricultural, actors. In a colloquium, a collective vision for the project was constructed, integrating other functions of farmland such as conservation and leisure activities. Many meetings were organised over a three‐year period and formal presentations were made to the municipality. The project is ongoing, including new farm operations and the reinforcement of local markets for marketing mainly organic produce. The area is now an integral part of an emerging ‘green belt’ of the Montreal agglomeration and is already part of a ‘green coalition’ of both urban and peri‐urban actors (farmers and non‐farmers), and an emerging food system movement which represents a more holistic approach to food production.  相似文献

Spatial analysis in geoarchaeological applications can be improved by implementing a wider set of geoecological parameters, in order to provide more precise results. The aim of the paper is to show how geoscientific ground-truth and techniques can be adopted for detailed archaeological studies using a comprehensive set of environmental variables that might have influenced ancient settlement patterns. The project focuses on spatial patterns of archaeological sites as well as Bronze Age communication paths in Central Crete by applying a multi-method approach (surveying, remote sensing, DEM analysis, least-cost analysis, candidate site detection, predictive modelling, etc.). In contrast to conventional archaeological GIS applications this enhanced strategy offers promising prospects regarding landscape and settlement modelling.  相似文献

A robust debate among coastal geomorphologists as to the processes by which beach‐ridge plains around Australia have formed was initiated by a former President of the Institute of Australian Geographers. This review gives special consideration to the work of Jack L. Davies, whose academic contributions to coastal geomorphology in Australia have not always been appropriately acknowledged when explaining how similar plains have evolved elsewhere in the world. Davies recognised that relatively steep storm waves caused erosion (cut) on beaches, whereas less steep long‐period swell waves returned sand (fill). He considered the beach berm to be the nucleus on which a beach ridge formed, which could subsequently develop into a foredune, in contrast to cobble ridges that were deposited during storms. Offshore conditions regulate supply of sand to the shoreline, partly through effects on wave refraction, with higher rates of supply where the nearshore is shallow. It was apparent to Davies that the elevation of successive ridges might, but not necessarily, provide evidence of past changes of sea level, despite adornment by variable amounts of windblown dune sand. Morphodynamic understanding of long‐term coastal evolution, based on radiocarbon dating chronologies, has demonstrated that Australian coastal plains formed over the past ~6,000 years when sea level has been close to its present level, in contrast to several documented locations in the northern hemisphere where the sea has been rising for the past few millennia. Particularly insightful were observations by Davies that ridge formation could be influenced by a range of factors including changes in sea level, storminess, or sediment supply. These factors acting singly or in combination seem likely to change in the future. Understanding such responses remains a high priority and can be addressed by new technologies, such as light detection and ranging, optically stimulated luminescence dating, ground‐penetrating radar, and computer simulation.  相似文献

A New Zealand example illustrates the potential of foraging efficiency (FE) measures to inform not only on human-prey dynamics, but also to help identify situations where mobility is constrained or stimulated. Marked declines in Māori molluscan FE, coupled with increased shellfish usage, are identified over a ca. 450-year period at the coastal locality of Harataonga Beach, New Zealand. The potential effects of climate change are considered using newly available southwest Pacific multi-proxy records and temperature sensitive species, but correlations are lacking. The molluscan results signal possible restrictions on logistic and/or residential mobility in late prehistory, while evidence from the broader cultural landscape points to increasing agricultural investments and marked social competition. The Ideal Free Distribution model (IFD) is used to consider regional-scale interactions between foraging efficiency, agricultural developments, and competition, and their effects on mobility. Geographic and temporal variation in the patterning and causes of population movements is highlighted through this model, particularly differences between large game foragers in the south and populations with mixed economies in the north. In late prehistory, many northern areas including Harataonga apparently experienced reductions in the geographic scale of population movements, coupled with intensified intra-territorial mobility. The latter was an outcome of labour being widely dispatched across tribal territories, quasi-specialisation in subsistence tasks, and pooling and exchange of resources through a variety of social mechanisms which often involved population movements.  相似文献

Despite being a major site of recent population growth and, arguably, a key arena for sustainability concerns, the rural‐urban fringe has received relatively little attention in the literature concerning Australian cities and urban policy. To address this shortcoming the authors review post‐World War II efforts to plan the rural‐urban fringes of Sydney and Adelaide and find a number of issues for contemporary policy‐makers. First, the fringe is becoming increasingly complex due to multi‐faceted demographic change, a broadening economic base and demands for better environmental management, all within the context of an evolving understanding of sustainability. Second, water resource management, partly under the auspices of integrated natural resource management, is assuming a much higher priority than in early fringe planning endeavours, which emphasised urban containment, agricultural land protection and landscape conservation. Third, and partly as a consequence of this shift of priorities, there is also evidence of changes to the nature and focus of policy tools used in the fringe, with land management concerns now cutting across traditional land use planning. Finally, and fundamentally, these observations raise questions about how future governance of the fringe should be organised. Together these four themes pose an enthralling series of challenges for policy‐makers for which much more research and discussion are needed.  相似文献

A young adult male, context [825], exhibiting a suite of proliferative and erosive skeletal changes, was excavated from the old burial ground of St Marylebone, London, in 2005 by the Museum of London Archaeology Service (MoLAS). Although pathognomonic rhinomaxillary changes were absent, a number of lesions were of a type previously recorded in individuals suffering from lepromatous leprosy, including resorption of the alveolar process of the maxillae and the digits of the right hand, osteomyelitis in the left ulna and collapse of the left ankle. Whilst this infectious disease was widespread in medieval Britain, it had declined by the 19th century, and has been identified in only one other post‐medieval archaeological context. The right leg of [825] had been surgically amputated. This form of intervention was a recognised treatment for the complications of the disease, where neuropathic damage of limbs led to life‐threatening infection. The healing of the amputation demonstrates the success of the operation, and the skill of the surgeon. Although the identity of the affected individual is unknown, burial within St Marylebone cemetery implies a level of status not frequently associated with leprosy sufferers in the past.

For the Métis Nation in Canada, self‐government remains the ‘essence of the struggle’ for which their political leader, Louis Riel, sacrificed his life in 1885. As one of Canada's founding peoples, the Métis have sought to reclaim their Indigenous right to self‐government by establishing democratic governance bodies, enhancing their economic capacity and pursuing state recognition of their rights. In addition to these efforts, the Métis have been developing a national constitution, which is anticipated to form the basis of a government to government relationship between the Métis Nation and the Canadian state. Through a case study of the Métis, this article explores the role of contemporary constitution‐building in rebuilding Indigenous nations from within and reclaiming self‐government in settler societies. We conclude that the Métis Nation's pursuit of these goals through constitutionalism will depend on its ability to build legitimacy internally amongst its citizens and externally with state decision‐makers.  相似文献
