Expanding the research parameters of geoarchaeology: case studies from Aksum in Ethiopia and Haryana in India

A wide-ranging geoarchaeological approach is put forward using two case studies in northern highland Ethiopia at Aksum and in Haryana province of northwestern India where the authors are part of collaborative archaeological research projects. Geoarchaeological approaches are well placed to underpin archaeological project design and contribute to the understanding and modelling of the human ecosystem legacy. There is also the potential to use that data to both inform wider audiences of the importance of long-term land-use dynamics in shaping our landscapes today and influencing modern land-use policy and implementation.     

Using Airborne LiDAR Survey to explore Historic-era archaeological landscapes of Montserrat in the Eastern Caribbean

Abstract

This article describes what appears to be the first archaeological application of airborne LiDAR survey to historic-era landscapes in the Caribbean archipelago, on the island of Montserrat. LiDAR is proving invaluable in extending the reach of traditional pedestrian survey into less favorable areas, such as those covered by dense neotropical forest and by ashfall from the past two decades of active eruptions by the Soufrière Hills volcano, and to sites in localities that are inaccessible on account of volcanic dangers. Emphasis is placed on two aspects of the research: first, the importance of ongoing, real-time interaction between the LiDAR analyst and the archaeological team in the field; and second, the advantages of exploiting the full potential of the three-dimensional LiDAR point cloud data for purposes of the visualization of archaeological sites and features.     

Assessing the effects of geomorphological processes on archaeological densities: a GIS case study on Zakynthos Island,Greece

While geomorphological processes are considered key factors in the distribution of archaeological surface finds, few studies have attempted to quantify the relationship between artefact dispersal and erosional/depositional patterns. This paper compares Unit Stream Power Erosion Deposition model (USPED) and Revised Universal Soil Loss Equation (RUSLE) and integrates the results in the archaeological finds’ density map of Zakynthos Archaeological Project. The study area (Palaiokastro), with artefacts dated from middle Paleolithic to medieval times, includes a steep terrain with a surrounding plain area, where the downslope erosion has considerably modified the distribution of archaeological remains. Through this study, it is possible to identify relationships between high artefact densities and stable/non-eroded surfaces, and on the other hand, low densities and eroded surfaces. However, the results indicate a degree of spatial variability, which modifies the predicted relationship. The consideration of the effects of these temporal and spatial patterns is crucial for developing effective sampling methods and accurately interpreting the archaeological record.     

Archaeology and roman society: Integrating textual and archaeological data

Although the collection of new data and the development of an enduring interest in theoretical concerns characterize much current work in Roman archaeology, the field continues to experience, tension between traditional classical archaeological approaches and practices borrowed from other branches of archaeology. This tension is most clearly visible with the integration of textual and archaeological data. How the dynamic between these provenances plays out in Roman archaeology can be seen in theoretical and methodological applications, the use of field survey, and the adoption of an Annaliste perspective by some Roman archaeologists. Text and archaeology are crucial contributors to the the study of early Rome and its origins, investigations in the capital for all periods, the study of Pompeii, and attempts to illuminate the chief characteristics of the Roman economy. Many advances in Roman archaeology have occurred largely as a result of a conscious attempt on the part of Roman archaeologists to properly contextualize textual data in light of the archaeological data, thereby providing a better balance between the two sets of information and liberating archeeology from being the “handmaid of history.”     

Unmanned Aerial Vehicle (UAV) Survey with Commercial-Grade Instruments: A Case Study from the Eastern Ḫabur Archaeological Survey,Iraq

Low-altitude photography in archaeology is now common practice at the scale of excavations; however, landscape-scale applications are a relatively new endeavor with promising analytical potential. From 2014–2016, an unmanned aerial vehicle (UAV) with a mounted camera was used to document sites recorded as part of the Eastern ?abur Archaeological Survey (E?AS), an archaeological reconnaissance project in western Dohuk Province, Iraqi Kurdistan. The E?AS team documented over 70 archaeological sites with the UAV, from single-phase artifact scatters, to archaeological remains with standing architecture, to tells that cover more than 30 hectares. Representative examples from this survey are presented here to outline the project workflow and primary output data layers, including digital orthomosaics and digital elevation models. The quality and utility of results are then assessed in relationship to available satellite-based data. Methods for analysis and interpretation are then considered to demonstrate applications in landscape archaeology.

The longitudinal study of land-use at Acconia: Placing the fieldwork of the survey archaeologist in time

Abstract

This article presents the results of the longitudinal study of land-use conducted at Acconia in southern Italy between 1980 and 2007. This is the first of several articles planned on the landscape dynamics that took place there over a span of 27 years. Here we trace the sequence of the steps in the work of the Acconia Survey and the evolution in our thinking that led to the start of the longitudinal study, outline the fieldwork conducted at Acconia in 2007 and 2008, and present the changes in land-use that took place between the first mapping in 1980 and the fourth one in 2007. The final section considers some of the implications of what we have observed for the development of method and theory in survey archaeology. One of the main conclusions to emerge from the longitudinal study is that the work of the survey archaeologist should be seen as situated in time.

The Integration of VHR Satellite Imagery,GPR Survey and Boring for Archaeological Prospection at the Longcheng Site in Anhui Province,China

This paper is focused on the joint use of non‐invasive and minimal intervention techniques for supporting archaeological prospection. Very high resolution (VHR) satellite imagery analysis and ground‐penetrating radar (GPR) and boring surveys were integrated for the study of the Longcheng site, located near Hefei city in Anhui Province, China, to test their effectiveness and efficiency in prospecting archaeological remains and evaluating their degree of preservation. First, target locations of potential archaeological structures were identified on a WorldView‐2 (WV‐2) satellite image through spatial and radiometric enhancement, interpretation and object‐oriented classification. Second, archaeological features extracted from the WV‐2 imagery were further investigated by a GPR survey that provided detailed cross‐checking information about buried remains. Finally, a subsequent boring survey was conducted across those prospective archaeological structures in order to map the stratigraphic sequences on the basis of colour, compactness and the inclusions contained in the soil, and then to test their correspondence with the GPR data. The boring led to detailed confirmation of the results produced by the remote sensing analyses and GPR surveys, as well as the discovery of datable artefacts. On the basis of all the integrated data, the preliminary layout and structure of the Longcheng site was reconstructed in GIS. Furthermore, the widths, lengths, heights and burial depths of these buried archaeological structures were estimated in detail.     

A Regional Approach to Ancient Urban Studies in Greece Through Multi-Settlement Geophysical Survey

The systematic exploration of large archaeological sites in the Mediterranean has evolved considerably since the “big dig” excavations. Pedestrian field surveying and remote sensing applications, including satellite and airborne image analysis, are now practical and relatively cost-efficient methods of characterizing large and diachronically diverse landscapes on regional scales. However, the use of geophysical techniques as a means for exploring manifold archaeological contexts is still in its infancy. In this paper, we highlight the advantages of archaeological geophysics to conduct regional surveys in the Mediterranean. Through a multi-site geophysical fieldwork campaign to investigate the patterns and dynamics of ancient cities in Greece, we show how geophysics offer new opportunities for characterizing the spatial attributes and regional dynamics of urban landscapes, and, in doing so, we make an argument for its wider adoption on regional survey projects.     

Using Sector‐Scan Sonar for the Survey and Management of Submerged Archaeological Sites

This article reports the results of using a sector‐scan sonar to record diverse submerged archaeological sites in shallow and deep water. The Kongsberg MS1000 sector‐scan sonar was developed for commercial applications, typically underwater inspections of bridges, dams, ports and harbours. The ability of the device to rapidly generate high‐quality, geometrically accurate scans of submerged features, coupled with its ease of use and deployment make it a potentially important, yet largely overlooked, tool for survey and management of underwater archaeological sites. As one of several technologies available, the paper examines its advantages and limitations, and considers, through case studies, under which conditions it is most effectively deployed.     

现代中国环境考古研究模式的分析

本文将1987年以来的中国环境考古研究称为"现代中国环境考古研究",并将之归纳为"考古地理的环境考古研究模式"、"文化历史环境考古研究模式"和"资源环境考古研究模式"。本文对这三种研究模式的合理性进行了分析。接下来,从考古学的基本理论假设出发,指出环境考古学、文化历史考古学之间并没有严格的继承关系,中国环境考古研究的最大问题是核心概念的不匹配。最后,通过考察西方环境考古研究和考古学史,本文提出应该用文化适应,即"考古学中的文化"取代考古学文化而将之作为核心概念进行环境考古研究,让中国环境考古摆脱文化历史考古学概念体系的束缚。     

Project SAMPHIRE: Crowd Sourcing Maritime Archaeology data off Scotland's West Coast

Perhaps the greatest barrier to effective management of underwater cultural heritage is the lack of data on the nature and location of offshore archaeological resources. This is a problem shared with terrestrial archaeology, but is particularly acute due to the limitations of survey techniques in the underwater environment. In Scotland <15% of known ship losses from the last 200 years have been located and the record is far less comprehensive for earlier periods, verging on a near total data gap. Most known archaeological sites in Scottish waters have been discovered through large-scale sonar survey of relatively low resolution and a considerable bias has been introduced in the archaeological record; this has favored the discovery and documentation of larger and more recent, often upstanding, metal shipwrecks. This article presents the methods and results from a three-year project designed to reduce this bias by demonstrating large-scale prospecting for maritime archaeology through a community-based crowd-sourcing approach. Project SAMPHIRE (the Scottish Atlantic Maritime Past: Heritage, Investigation, Research and Education Project) was geographically focused on the west coast of the Scottish mainland and was undertaken between 2013 and 2015, resulting in a large number of new archaeological discoveries, including shipwrecks, aircraft, and other material of a much more varied nature than what is typically found through large-scale hydrographic surveys.     

Developing a Landscape History as Part of a Survey Strategy: A Critique of Current Settlement System Approaches based on Case Studies from Western New South Wales,Australia

In Australia, geomorphological change since the late nineteenth century ensures surface artifact visibility but the contribution of full coverage regional survey to an understanding of past landscape use is limited by the lack of easily datable artifacts. Here, we describe a multi-stage survey strategy based around intensive archaeological, geomorphological and chronological studies as an alternative to traditional site-based approaches. We view the formation of the archaeological record as a sedimentary process and use a geomorphological approach to understand the history of landscape use from surface artifact scatters. We pay particular attention to recording datasets with reference to the timescales over which they have accumulated, and we discuss the types of behavioral inferences that can be drawn from the results of intensive survey, illustrated using the results from our western New South Wales research.     

Modelling spatial heterogeneity and nonstationarity in artifact-rich landscapes

In this paper we consider a crucial issue for survey archaeology: how we identify and make sense of the heterogeneous and often inter-dependent behaviours and processes responsible for apparent archaeological patterns across the landscape. We apply two spatial statistical tools, kriging and geographically weighted regression, to develop a model that addresses the spatial heterogeneity and spatial nonstationarity present in the pottery distributions identified by our intensive survey of the Greek island of Antikythera. Our modelling results highlight a clear spatial structure underlying different scales of pottery density as well as locally varying relationships between pottery densities and several environmental variables. This allows us to develop further testable hypotheses about long-term settlement and land-use patterns on Antikythera, including more explicit models of community organisation, and of the relationship between the island's geomorphological structure and its history of past human activity.

Detecting Late Holocene cultural landscape modifications using LiDAR imagery in the Boreal Forest,Susitna Valley,Southcentral Alaska

The subarctic boreal forest, or taiga, is the largest biome in the world but has received minimal archaeological research because of its remoteness and difficult working conditions. In Southcentral Alaska the most common archaeological sites are surface manifestations of proto-historic semi-subterranean caches once used for food storage and living structures. However, in dense summer vegetation, these small-scale features are difficult to locate without high intensity pedestrian survey. To test the usefulness of LiDAR data for archaeological prospection in the taiga, we compare LiDAR imagery to the known distribution of small-scale semi-subterranean cultural features. The use of LiDAR, when complemented with Sky-View Factor, has proven valuable in identifying relatively small semi-subterranean features though it does not replace on-the-ground investigation. Nevertheless, the application of LiDAR to locate low density and small-scale cultural features is widely applicable across the subarctic in densely vegetated contexts and may assist in significantly expanding our current knowledge of land-use patterns and site distributions in logistically challenging places.     

Making a Mountain Out of a Molehill? A Low-Cost and Time-Efficient Molehill Survey of the Lost Medieval Harbor Site of Monnikerede,Belgium

Grasslands pose a particular problem for archaeological survey involving artifact assessment, as no material is plowed up to the surface. Although finds in molehills are often the only source of information available on sites with such low visibility, an archaeology of molehills has thus far been largely disregarded. Yet, by applying a low-cost and time-efficient methodology, both the potential and the pitfalls of molehill archaeology come to the forefront. At the medieval harbor site of Monnikerede, it was possible to assess material culture and to locate certain structural elements. However, when artifact densities were compared with the underlying geophysical anomalies, a more complex relationship appeared at the level of individual features.     

Thoughts on new approaches to combining the archaeological and historical records

For decades, archaeologists have looked for an appropriate means to integrate archaeological findings with the textual record. Often, in the past, the written word has been privileged over material remains. In this summary, which draws in part from the individual papers in this special issue, a new, more balanced approach that gives increased weight and greater independence to archaeological data is proposed. A series of implications and suggestions for current theoretical development in archaeology are advanced.     

Archaeological Ethnography,Heritage Management,and Community Archaeology: A Pragmatic Approach from Crete

This article examines the introduction of archaeological ethnography as an approach to establish positioned research and bring context-specific and reflexive considerations into community archaeology projects. It considers recent critiques of heritage management in archaeology and the role of archaeologists as experts in it, contending that smaller and less prominent sites exist in different contexts and pose different problems than large-scale projects usually addressed in the literature. We describe how the ‘Three Peak Sanctuaries of Central Crete’ project, investigating prehistoric Minoan ritual sites, involves communities and stakeholders and what demands the latter pose on experts in the field. Archaeological work is always already implicated in local development projects which create and reproduce power hierarchies. It is therefore important that archaeologists maintain their critical distance from official heritage discourses, as they are materialized in development programmes, while at the same time engaging with local expectations and power struggles; they also have to critically address and position their own assumptions. We use examples from our community archaeology project to propose that these goals can be reached through archaeological ethnographic fieldwork that should precede any archaeological project to inform its methodological decisions, engage stakeholders, and collaboratively shape heritage management strategies.
