KNV01623 Kalvehavegård
No full textBeretning for forundersøgelse af et 16.760 m2 stort areal forud for anlæggelse af arbejdsareal i forbindelse med kloakseparering i Kalvehave. Desuden overvågning af traceer, fortrinsvis i den sydlige, kystnære del af byen, hvor der var risiko for at støde på stenalder lokaliteter og befæstning. Der blev på arbejdsarealet fundet enkelte stolpehuller og gruber, der blev snittet og registreret. Yderligere undersøgelser var dog ikke nødvendige, og arealet blev frigivet kort efter forundersøgelsen
The reproduction of fire-born soot for comparative cleaning tests on heritage objects
No full textThis work describes the design of reproducible mock-ups with controlled soot deposition, created to support comparative cleaning tests within the EU Horizon MOXY project. The latter develops atmospheric, plasma-generated, monoatomic oxygen as a cleaning method to remove (amongst others) fire-born soot from heritage objects. A literature review highlights the complexity of soot while revealing a lack of focus on the representativeness of artificial soot in previous studies. We benchmarked two approaches: (I) indirect/cold application of pre-fabricated soot and (II) direct/hot application via ongoing combustion. The results demonstrate that direct combustion yields soot with markedly different physical and chemical characteristics. Chemical analysis (Raman, XRPD, TGA, EGA-MS, XPS) and microscopic imaging (3D optical, SEM) revealed differences in composition, morphology, and deposition behaviour on substrates like paper, silk, paint and plaster. We selected the ‘smoke drum’ method as the most practical and reproducible approach for mimicking fire-born soot in heritage cleaning research

PastCoast – Using Ground Penetrating Radar data for high resolution chronological investigations of landscape change
No full textStudying land use, transportation, and settlement patterns impacted by isostatic uplift, flash floods, and coastal erosion is essential for understanding past human activities, especially in the face of ongoing climate change. Non-intrusive geophysical methods, particularly 3D ground-penetrating radar (GPR) and digital elevation models (LiDAR), provide valuable insights into the relationship between past human activities and environmental changes. This paper presents examples from coastal Iron Age sites in Norway, demonstrating how geophysical methods and remote sensing can help to understand slow coastal landscape development and prehistoric human responses to shoreline changes. Large-scale datasets collected in Denmark and Norway provide data on palaeohydrography, palaeotopography, and geomorphological processes, with an emphasis on palaeo beach ridges and sea level changes
New investigations of the Hjortspring boat: Dating and analysis of the cordage and caulking materials used in a pre-Roman iron age plank boat
No full textThe Hjortspring boat is the only intact example of a prehistoric sewn plank boat ever found in Scandinavia. Built from lime wood planks lashed together with cordage, the boat represents the maritime technology used by some of Northern Europe’s earliest seafarers. This article reports new analysis of the cordage and caulking material used in the construction of the Hjortspring boat. We provide the first ever direct date for the boat based on materials from the original excavation finds, with lime bast cordage from the boat carbon dated to between 381 and 161 BCE. We report the results of GC-MS analysis of the material used to caulk the boat, which shows that it was made from a mixture of animal fat and pine pitch. We argue that the use of pine pitch in the boat’s construction indicates that the boat was not built on the Jutland peninsula and instead came from a region with more abundant pine forests. Based on the dispersal of pine forests in Northern Europe during the first millennium BCE, we propose the Baltic Sea Region east of Rügen and Scania as a likely source for the boat and its crew. We also analyze intact cordage fragments and imprints of cordage on caulking material in order to describe the sewing and rope-making techniques that were used to construct the boat. Finally, we report on the discovery of a partial human fingerprint found on a fragment of caulking material. This remarkable fingerprint provides a direct link to the ancient seafarers who used this boat. Together, these results shed new light on methods and materials used to build Scandinavia’s first plank boats and raise new questions regarding our understanding of early maritime societies in Northern Europe.The Hjortspring boat is the only intact example of a prehistoric sewn plank boat ever found in Scandinavia.
