Archaeology and waterlogged wood

Museum International, 1987
The authors describe several methods of preserving waterlogged wood used by Swiss archaeologists since the 19th century to treat finds from lakeside settlements. Large dugout canoes discovered in the second half of the 19th century were unsuccessfully treated with natural substances such as beeswax, linseed oil, resins or glues.

Non-destructive preservation state estimation of waterlogged archaeological wooden artifacts

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2023
Non-destructive preservation state estimation is an essential prerequisite for the preservation and conservation of waterlogged archaeological wooden artifacts. Herein, Near Infrared (NIR) spectroscopy coupled with orthogonal partial least squares discriminant analysis (OPLS-DA) were applied to assess sixty-four waterlogged archaeological woods ...

Microbial degradation of waterlogged archaeological wood

Journal of Cultural Heritage, 2012
Abstract Waterlogged archaeological wood is degraded very slowly compared to wood decay above ground. The special environmental conditions below ground, results in a prolonged decay process that under extremely low oxygen concentration only allow bacterial degradation of wood.

Waterlogged archaeological wood—chemical changes by conservation and degradation

Journal of Raman Spectroscopy, 2006
AbstractConservation of waterlogged archaeological wooden artefacts from the Nydam Bog in the southern part of Denmark was investigated by Raman spectroscopy. Two different conservation methods were used: the cellosolve/petroleum method and the polyethylene glycol (PEG)/freeze‐drying method.

Preliminary ¹H NMR Study on Archaeological Waterlogged Wood

Annali di Chimica, 2005
AbstractMagnetic Resonance Relaxation (MRR) and Magnetic Resonance Imaging (MRI) are powerful tools to obtain detailed information on the pore space structure that one is unlikely to obtain in other ways. These techniques are particularly suitable for Cultural Heritage materials, because they use water 1H nuclei as a probe.

Bacteria as Important Degraders in Waterlogged Archaeological Woods

hfsg, 1996
An electron microscopic study of archaeological woods from different sites and of different ages revealed that the woods had been attacked by erosion bacteria, tunneling bacteria and soft rot fungi. Bacterial erosion appeared to be most widespread and was present independently as well as together with tunneling and soft rot attacks.

Physico-Chemical Characteristics of Waterlogged Archaeological Wood

hfsg, 1997
Waterlogged wood samples 300 to 100.000 years old of Picea abies, Pinus sylvestris and Quercus sp. from northern Europe (Norway, Sweden) that had been preserved in a glacier, burial grounds, house settlements, harbour installations and sunken ships in the sea were examined for changes in physico-chemical characteristics as compared to recent wood.
