  • Environmental archaeological investigation of samples from the Kaupang 2000 excavations
  • 2001
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • The Environmental Archaeology Lab was contracted in June 2000 to carry out palaeoenvironmental analyses on samples from the Kaupang excavation in Southern Norway. Excavation was carried out during that summer, and Pat Wagner (Sheffield University) was employed by the excavators to supervise initial sampling and teach the sampling and field processing methods. The sampled features included waterlogged deposits interpreted as wells and latrines, and deposits from pits ofunknown function. Fossil preservation varied considerably, being both a function of modern conditions and the hydrological history of the deposit, and one cannot guarantee that all material sare equally preserved.A total of 15 soil samples were submitted to the lab, all of which were to undergo macrofossil analysis, and 6 of which were, in addition, to be analysed with respect to their fossil insect assemblages. As a matter of routine all samples underwent rudimentary soil chemistry analyses. Table 1 summarises the samples and the analyses performed upon them. In addition to the soilsamples received, several jars of test material floated on site were included, these were cursorily examined as a control to the soil samples, i.e. their faunas were checked against the appropriate sample to see whether any extra species were present in the jars. These samples are not listed in the results as the faunas were too small to be of real analytical value.

  • Integrating human dimensions of Arctic palaeoenvironmental science : SEAD – the strategic environmental archaeology database
  • 2011
  • Ingår i: Journal of Archaeological Science. - : Elsevier. - 0305-4403 .- 1095-9238. ; 38:2, s. 345-351
  • Tidskriftsartikel (refereegranskat)abstract
    • Environmental change has a human dimension, and has had so for at least the last 10 000 years. The prehistoric impact of people on the Arctic landscape has occasionally left visible traces, such as house and field structures. More often than not, however, the only evidence available is at the microscopic or geochemical level, such as fossil insect and seed assemblages or changes in the physical and chemical properties of soils and sediments. These records are the subject of SEAD, a multidisciplinary database and software project currently underway at Umeå University, Sweden, which aims to create an online database and set of tools for investigating these traces, as part of an international research infrastructure for palaeoecology and environmental archaeology.

  • SEAD : Strategic Environmental Archaeology Database, planning report
  • 2006
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This document lays out a strategy for the development of SEAD – A Strategic Environmental Archaeology Database, which will facilitate the digitisation and accessibility augmentation of MAL’s existing data from nearly thirty years of work in the fields of archaeology and environmental science. SEAD will also provide a framework for the entry of data from all future research and consultancy work at MAL, and allow guest researchers and external partners to contribute to, and work with the same data. The planned system will be implemented at both local and internet levels, and be designed with an aim towards broadening its scope with external partners in the future. SEAD will be made available online in order to increase the ease of access to environmental archaeology data and encourage an expansion of both the discipline and Sweden’s role in it. This is inline with current EU strategies on enhancing research infrastructure, and providing a greater insight into human-environment interactions for long term planning.

  • The development and implementation of software for palaeoenvironmental and palaeoclimatological research : the Bugs Coleopteran Ecology Package (BugsCEP)
  • 2007
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis documents the development and application of a unique database orientated software package, BugsCEP, for environmental and climatic reconstruction from fossil beetle (Coleoptera) assemblages. The software tools are described, and the incorporated statistical methods discussed and evaluated with respect to both published modern and fossil data, as well as the author’s own investigations. BugsCEP consists of a reference database of ecology and distribution data for over 5 800 taxa, and includes temperature tolerance data for 436 species. It also contains abundance and summary data for almost 700 sites - the majority of the known Quaternary fossil coleopteran record of Europe. Sample based dating evidence is stored for a large number of these sites, and the data are supported by a bibliography of over 3 300 sources. Through the use of built in statistical methods, employing a specially developed habitat classification system (Bugs EcoCodes), semi-quantitative environmental reconstructions can be undertaken, and output graphically, to aid in the interpretation of sites. A number of built in searching and reporting functions also increase the efficiency with which analyses can be undertaken, including the facility to list the fossil record of species found by searching the ecology and distribution data. The existing Mutual Climatic Range (MCR) climate reconstruction method is implemented and improved upon in BugsCEP, as BugsMCR, which includes predictive modelling and the output of graphs and climate space maps. The evaluation of the software demonstrates good performance when compared to existing interpretations. The standardization method employed in habitat reconstructions, designed to enable the inter-comparison of samples and sites without the interference of differing numbers of species and individuals, also appears to be robust and effective. Quantitative climate reconstructions can be easily undertaken from within the software, as well as an amount of predictive modelling. The use of jackknifing variants as an aid to the interpretation of climate reconstructions is discussed, and suggested as a potential indicator of reliability. The combination of the BugStats statistical system with an enhanced MCR facility could be extremely useful in increasing our understanding of not only past environmental and climate change, but also the biogeography and ecology of insect populations in general. BugsCEP is the only available software package integrating modern and fossil coleopteran data, and the included reconstruction and analysis tools provide a powerful resource for research and teaching in palaeo-environmental science. The use of modern reference data also makes the package potentially useful in the study of present day insect faunas, and the effects of climate and environmental change on their distributions. The reconstruction methods could thus be inverted, and used as predictive tools in the study of biodiversity and the implications of sustainable development policies on present day habitats.
