Timber supply through time - Copenhagen waterfronts under scrutiny.

Dendrochronology is not a new method for attaining high-precision dates for archaeological and historic remains of timber. But the extent to which dendrochronology is utilized to attain detailed precision of the dating of complex wooden structures can suffer from the fact that the method is often applied in commercial archaeology, where the extent of analysis is severely limited by cost constraints. Instead of lamenting the potentially lost levels of detail that might have slipped through over the years, it is hoped that by presenting the potential of high chronological precision, that necessitates extensive sampling of timber and wood remains on archaeological sites, a new future will be promoted, in which new wide-ranging sampling strategies will become a more normal practice in archaeology, in both the research and commercial spheres. In this paper, I present some case studies where extensive tree-ring analysis of well-preserved wood remains have resulted in annual chronological detail, allowing an insight into the processes of building, and into the duration of structures that comprised the built environment of past peoples' lives. In addition, we should not discuss precision dating for urban archaeological study without also touching on the subject of timber trade and timber provenance. Tree-ring studies are increasingly providing us with high precision provenance identification, not just for shipwrecks, barrels and other 'portable' objects. It is also allowing us to map trade in bulk structural timber. These analyses are providing us with insights into links between territories.
