Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection
Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment echosounder systems. We apply electronical beam steering on a parametric sediment echosounder. Using seis…
Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)
Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited due to the lack of survey methodologies adapted to dynamic intertidal environments. In this study, we prese…
Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia
Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos. Olympia is situated on the northern fringe of the Makrisia Basin. Due to its position between the two rivers, the sanctuary was covered by several metres of sediment (…
Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments
Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and geoarchaeological methods in a near coastal, lagoonal surrounding, posing questions about its connection to the sanctuar…
The Lake of Olympia: Sedimentary evidence of a mid- to late Holocene lake environment in the vicinity of ancient Olympia (western Peloponnese, Greece)
Olympia (western Peloponnese, Greece) is known as venue for the Panhellenic Games in ancient times. The wider region is located within a complex tectonic setting and was affected by crustal uplift up to 30 m since the mid-Holocene. Our study consists of a comprehensive investigation of the Basin of Makrisia and the adjacent Basin of Ladiko in the vicinity of ancient Olympia aiming to reconstruct the Holocene landscape development. In addition to …
A Previously Unknown Building Structure in Ancient Olympia (Western Peloponnese, Greece) Revealed by Geoarchaeological Investigations and Its Interpretation as a Possible Harbor
The ancient site of Olympia is located on the northern fringe of the Basin of Makrisia at the confluence of the Kladeos and Alpheios rivers (western Peloponnese, Greece) and was used as a venue for the Panhellenic Games from Archaic times until the 4th century AD. Geophysical prospection (frequency domain electromagnetic induction and electrical resistivity tomography) was carried out as a basis for detailed geoarchaeological investigations. In d…

Structure of the Multiphase Chalcolithic Tell Chiselet–Grădiștea Fundeanca (Romania) From SH‐Wave Full‐Waveform Inversion, Borehole Geophysics and Coring
The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small‐scale heterogeneities and pronounced topography constitute challenging conditions for noninvasive geophysical…
Multi‐Method Structural Investigation of the Schneiderberg–Baalberge Burial Mound (Saxony‐Anhalt, Germany) Including Seismic Full‐Waveform Inversion (FWI)
The construction history and subsequent usage of burial mounds are an important testimony for socio‐economic transformation in prehistoric societies. The Baalberge–Schneiderberg burial mound, subject of the presented study, falls in this category as it is considered as an important monument that indicates the emergence of early social stratification during the Chalcolithic period in central Europe. This hypothesis relies on the chronological deve…
A novel seismic full waveform inversion approach for assessing the internal structure of a medieval sea dike
Coastal protection in the form of dike constructions has a long history at the German North Frisian coast dating back to the High Middle Ages. As the vast majority of the dikes built prior to the devastating storm surges of the Middle Ages have been irretrievably destroyed, mostly sparse remains and only a few well preserved of these medieval dikes are found along the German North Frisian coast and within the Wadden Sea. Not all details of their …

What over 100 drillings tell us: A new method for determining the Koenigsberger ratio of soils from magnetic mapping and susceptibility logging
We investigate the relative fractions of remanent and induced magnetization of the fillings of neolithic long pits in order to develop remanent magnetization as an additional parameter for the archaeological interpretation of magnetic maps. We determine the Koenigsberger ratio – the ratio between induced and remanent magnetization intensities – for key targets by combining magnetic mapping with downhole measurements of susceptibility, numerical m…
Reconstructing the palaeoenvironment at the early Mesolithic site of Lake Duvensee: Ground-penetrating radar and geoarchaeology for 3D facies mapping
We investigate the landscape development of the early Mesolithic hunter-gatherer sites of Duvensee (10000–6500 cal. BCE). Based on ground-penetrating radar (GPR) and geoarchaeological drillings, we present for the first time a three-dimensional (3D) reconstruction of the palaeoenvironment of 63 ha covering subarea of the former lake during the Mesolithic. The archaeological aims were (1) to detect the location of former islands possibly hosting h…
Deciphering archeological contexts from the magnetic map: Determination of daub distribution and mass of Chalcolithic house remains
The unique size and development of prehistoric megasites of the north Pontic Cucuteni-Tripolye Chalcolithic groups (4100–3600 BCE) challenge modern archeology and paleoecology. The extremely large number of houses (approximately 3000, mostly burned) necessitates the development of multidisciplinary technologies to gain a holistic understanding of such sites. In this contribution, we introduce a novel geophysical methodology and a detailed analysi…
Imaging a medieval shipwreck with the new PingPong 3D marine reflection seismic system
We present a new three‐dimensional (3D) marine seismic data acquisition system, named PingPong , developed for archaeological prospection in shallow water. Prospection targets for the system are ancient harbour sites and sedimented remains of shipwrecks. The prospection of such targets often means working at the transition from land to water, in areas of only a few meters of water depth and hardly accessible waters. An acquisition system for such…
Adaptations and transformations of hunter-gatherers in forest environments: New archaeological and anthropological insights
Like any other living being, humans constantly influence their environment, be it intentionally or unintentionally. By extracting natural resources, they shape their environment and also that of plants and other animals. A great difference setting people apart from all other living beings is the ability to construct and develop their own niche intentionally, and the unique tool for this is cultural behaviour. Here, we discuss anthropogenic enviro…
On the Ability of Geophysical Methods to Image Medieval Turf Buildings in Iceland
Structures in Iceland were traditionally built of turf, earth and, to a lesser extent, stone. As turf was the primary construction material, the contrast in geophysical parameters between building ruins and surrounding soil is expected to be low. To investigate the extent to which the remains of turf buildings can be detected by geophysical measurements, we applied several geophysical techniques to a known turf ruin in southwestern Iceland. The m…

Detection and localization of chamber tombs in the environs of ancient Olympia, Peloponnese, Greece, based on a combination of archaeological survey and geophysical prospection
Mycenaean chamber tombs are composed of air‐filled burial cavities and, therefore, can be detected by non‐invasive geophysical methods. In this study, an electrical resistivity tomography (ERT)‐based approach was used to detect graves at three different sites in the area surrounding ancient Olympia. We collected ERT data at the necropolis of Mageiras‐Kioupia, where a number of chamber tombs had already been located and partly excavated in order t…

Rayleigh‐wave Resonance Analysis: A Methodological Test on a Viking Age Pit House
Seismic surface‐waves may show amplitude resonances at certain frequencies depending on the thickness and elastic parameters of near‐surface layers. We investigate if resonance frequencies of Rayleigh‐waves, (seismic surface‐waves polarized in the vertical plane) can be used to prospect archaeological remains of small‐scale buildings such as pit houses. Our test site is a newly detected Viking age village on the island of Föhr (north Germany) whe…
