is the dating and study of annual rings in trees.
raises questions about the nature of the AD 536 dust-veil event.
This invitation to tender relates to the conclusion of a framework agreement with a consultant to carry out assistance in macro fossil analysis, dendrochronology
Tomorrow's topic is dendrochronology
, a method used to date buildings looking at tree rings/wood cores.
Dietrich Hakelberg from the Institute of Forest Growth of the University of Freiburg has succeeded in precisely dating four water wells built by the first Central European agricultural civilization with the help of dendrochronology
or growth ring dating.
The texts are very well written, documented, and referenced by the authors --all leading experts in the field--and everyone raises crucial questions about the operational aspects of the construction process, the limitations scholars are confronted with in their efforts to sharpen the dating of the different parts of a building, and what the new methods of analysis involving laser techniques, for instance, can reveal of the sub-surfaces (non-visible parts) of a Gothic building when combined with a more traditional method such as dendrochronology
In addition to the historical research there is a detailed technical investigation into Rembrandt's methods and materials, using infrared reflectography, polynomial texture mapping, dendrochronology
and x-radiography, allowing a clearer path for the interpretation of the painting, in whose 'making' there were evidently a number of stages.
Advanced classes can get into the details of wood structure or explore dendrochronology
(see "Extensions" at end of article).
EXPLORING THE URBAN OLD-GROWTH: DENDROCHRONOLOGY
OF THE FERNBANK FOREST, Megan Chapman *, M.
Well-illustrated with color and b&w photos, drawings, maps, and tables, the study presents analysis of the excavation and finds, the archaeological sequence, and specialist reports on coins, pottery, inscriptions and graffiti, timber, dendrochronology
, and environmental analysis.
is a precise science of using annual growth rings of trees to understand climate in the past.
