State-of-the-art of Ground-Based Geophysics for Archaeological Prospection and Paleo-landscape studies in Denmark

Sammendrag

This paper presents the current status of geophysical methods in Denmark and outlines the state-of-the-art approach based on recent case studies. As recent developments in hardware and real-time-corrected positioning have made fast and accurate geophysical data acquisition feasible, this provides interesting, new venues for archaeological pros-pecting and paleo-landscape understanding. In Denmark, however, the lack of in-house equipment, expertise and experience has hampered a proper application and acceptance for integrating geophysical data in archae-ological projects. Still, within the last decade, some exciting results and development have led to new and promising applications (Stamnes et al., In press). The presented cases are as follows: Utilizing elctromagnetic induction through dedicated processing and inversion schemes to ensure non-biased soil structures can improve inter-pretation of the geological settings around archaeological sites. This scheme has been used to resolve palaeo channels (Christiansen et al., 2016), in situ preservation manage-ment solutions (Tjellden et al., 2016), and Viking Age fortification mapping (Kristiansen et al., 2022). Better integration of geophysics into research, curatorial and developer funded practice, has recently been achieved using fluxgate gradiometry with an emphasis on intensive small-scale investigations in areas inaccessible to motorised arrays such as woodland, pro-tected cultural and natural heritage sites. Successful examples include surveys of megatli-hic tombs funerary cairns and fortifications in woodland.Towed magnetometer arrays provide a rapid and effective means of identifying both fer-rous objects such as tools or weapons, as well as earth materials such as clays that have been fired in a kiln. These instruments, specifically the 8-gradiometer array system tMag from Aarhus University, have been successfully applied in a variety of locations such as Ørregård (Kass et al. 2021) and Fæsted. Unfortunately, the lack of accessible software for detailed interpretation often prevents the full use of the available information in the data.As part of the research project PastCoast (Stamnes 2022), a series of Danish coastal sites known from histrorical investigations and metal detecting finds only have been investigat-ed with large-scale, high-resolution ground penetrating radar and magnetometer surveys. These involve the sites of Lundeborg and Strandby on Fyn, as well as the sites of Langelands gaarde and Vester Vandet in northern Jutland. One of the aims is better to understand the deposition history of the archaeological objects and investigate if subsoil features detect-able by geophysical methods can explain their spatial distribution. In addition, the data will be used to understand the palaeotopography and landscape formation better. Finally, based on these cases we discusses how the recent developments of hardware and software, and dedicated data processing, for archaeo-geophysics prospection can make some or all the discussed instruments acceptable as standard methods within Danish cul-tural heritage management.
