Turku-QUSP (QUB)

Jump to: navigation, search

Turku-QUSP (QUB) consists of recent oak samples found in the QUB collection[1] and covers the timespan 1719-1984. It is supposed to be from the Turku area in southwestern Finland, according to available information. This assumption is at least not contradicted by checking towards available Scandinavian and Baltic Oak references. It may be a good idea to remove the very oldest part when creating a master of this collection.

  1. QUB:Q5423 to QUB:Q5467, but three of them were excluded because of probable errors, QUB:Q5447 (duplicated ring at 1805) and QUB:Q5449 (low corr in a segment). Also a few "multi-radii" samples were excluded when a mean value sample was present.
