Degradation of Archaeological Wood Under Freezing and Thawing Conditions—Effects of Permafrost and Climate Change
The degradation of archaeological wood at freezing and thawing temperatures is studied at the site of Q ajaa in W est G reenland through a combination of environmental monitoring, measurement of oxygen consumption and microscopy of wood samples. Permanently frozen wood is still very well preserved a...
