Dendro dating service
Dendrochronology (or tree-ring dating ) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed in order to analyze atmospheric conditions during different periods in history.
Dendrochronology is useful for determining the timing of events and rates of change in the environment (most prominently climate) and also in works of art and architecture, such as old panel paintings on wood, buildings, etc.
What impact does the use of residual biomass have on seedlings?
Boreal forest: a tool to predict regeneration after fire.
Douglass sought to better understand cycles of sunspot activity and reasoned that changes in solar activity would affect climate patterns on earth, which would subsequently be recorded by tree-ring growth patterns ( i.e. The rings are more visible in temperate zones , where the seasons differ more markedly.
The inner portion of a growth ring is formed early in the growing season, when growth is comparatively rapid (hence the wood is less dense) and is known as "early wood" (or "spring wood", or "late-spring wood"  ); the outer portion is the "late wood" (and has sometimes been termed "summer wood", often being produced in the summer, though sometimes in the autumn) and is denser.
These results challenge extant interpretations of Scandinavian Bronze Age textile provenance, and demonstrate the complexity of exchange networks in wool textiles during this period.Data and study description information can be contributed by emailing decadal format data files to [email protected] the data files do not include header information, please also complete the metadata portion of our data contribution template (available at the link below) and email template along with the decadal format data files.The cal prefix indicates that the dates are the result of radiocarbon calibration using tree ring data.Calibrated radiocarbon date should be expressed in terms of cal BP/BC/AD.
