Applications of satellite remote sensing for research and heritage management in Indian prehistory

Multidisciplinary spatial studies are relatively limited in Indian archaeology, despite their potential for research and heritage management. This paper discusses applications of satellite remote sensing, field studies and GIS, in the context of Palaeolithic archaeology. The study region covers an area of around 8000 km², in the state of Tamil Nadu, South India, and is characterized by a rich and diverse Palaeolithic record. Satellite images of varied spatial resolutions were interpreted to address both regional and site-specific research questions. Thematic maps were generated from satellite data and refined with intensive field investigations. These were used for demarcating sources of raw material, and in investigating variability in the distribution of sites through time in relation to a range of geological and geomorphological features. Satellite data and field studies also aided in mapping impacts on sites resulting from modern landuse patterns. The paper also discusses the development and testing of a model to detect potential areas where new sites may be rapidly located.     

Techniques for Integrating Macrobotanical and Microbotanical Datasets: Examples from Pre-Hispanic Northwestern Honduras

What are useful quantitative approaches in situations with highly variable data quantities, contexts, and sampling strategies? How can paleoethnobotanical findings be interpreted without over-representing data or selling results short? Described here are several major issues and potential solutions. The four sites of the study are located northwestern Honduras, a region with fairly hostile environments for paleoethnobotanical preservation. For this reason, several types of botanical residues are combined to provide a more holistic picture of past ethnobotanical practices. In some cases, these data prove to be complementary, while in others, they are corroborative. This article includes tactics for integrating multiple sample protocols, multiple and overlapping diagnostic elements, multiple and overlapping clade categories, multiple and overlapping samples in a single locus, multiple and overlapping formation processes, and multiple and overlapping cultural practices. In each section, the issue, sampling strategies, quantitative approaches, and a few results are described.     

Geographies of everyday nationhood: experiencing multiculturalism in Melbourne

In this article, we explore the geographies of nationhood manifest in everyday life, arguing that our quotidian surroundings continually reproduce the nation as we engage with them. We show that nationhood is obvious and ubiquitous in the lives of people when they are asked to attune to it, and that even when not in the forefront of attention, it partly informs how we make sense of our daily experiences. This is not to claim that nationhood is fully formed or coherent, a separate substratum waiting to be tapped into or closely defined by an identifiable symbolic repertoire, if only we pay attention. Instead, we demonstrate that nationhood is emergent in everyday life, is reproduced continuously and intimately entangled with the sensations, routines, material environments, public encounters, everyday competencies, memories, aspirations and a range of other affective and embodied qualities that comprise how we understand and inhabit our worlds. This mundane experience involves shifting between reflexive and unreflexive states, and the method we deploy ‐ photo‐elicitation ‐ is devised to draw out these oscillations and heighten the attunement of participants to the usually unreflexively apprehended taken‐for‐granted national qualities of everyday space. Here, we aim to empirically foreground the neglected spatial dimensions that characterize the experience of banal nationalism.     

A rock magnetic record of Pleistocene rainfall variations at the Palaeolithic site of Attirampakkam,Southeastern India

Attirampakkam, an open-air stratified Palaeolithic site in southeastern India is the focus of ongoing studies to investigate the nature of Lower and Middle Palaeolithic occupation in relation to changing Pleistocene environments. The paucity of faunal or palaeobotanical remains at the site required the use of rock magnetic properties (χ_lf, χ_fd, χ_fd %, χ_ARM, SIRM, χ_ARM/SIRM, SIRM/χ_lf, χ_ARM/χ_lf, χ_ARM/χ_fd, S-ratio, HIRM and HIRM/IRM_300mT) as proxies for deciphering the palaeoenvironments and palaeoclimates of the region. Rock magnetic data from stratified deposits within excavated trenches show that the bulk of the sedimentation was intermittent with no subaerial exposure of sediments for long periods, and points to fluctuating wetter and drier climates associated with the Acheulian to Late Middle Palaeolithic levels. There is a general trend towards a wetter climate from Layer 5 upwards. Layer 7 offers evidence of bacterial magnetite (χ_ARM/χ_lf > 40 and χ_ARM/χ_fd > 1000), suggesting the onset of micro-anaerobic environments as a result of floods. Greigite is indicated in Layer 5 (SIRM/χ_lf > 30 × 10³ A m^?1), which indicates a reducing environment. Layer 2 represents an arid climate (higher proportion of haematite and a coarser magnetic grain size). Layer 1a again is indicative of an arid climate (presence of calcrete, magnetically “hard” minerals and coarser magnetic grain size). Results indicate that the southeast coast of India experienced a mostly dry tropical climate during the Pleistocene. The detected occurrence of a few notably more arid intervals did not disrupt occupation of the site by successive groups of hominins.
