This article describes two web-based tools for teaching dendrochronology, the scientific study of tree rings, and presents quantitative evaluations of their value in a large class. Because of its wide scientific applicability, dendrochronology is appropriate for teaching in a wide array of courses, including those in the fields of natural resources and life sciences. Until recently, professors ...
This paper provides a brief overview of certain issues related to climate modeling and the role that dendrochronology can play, and has already played, in this context. Modeling is an essential approach to investigating the future evolution of the climate system in response to human activities. Tree-ring chronologies, on the other hand, have the capability of providing key parameters for model ...
Existing data and theory do not support a recent assertion that upwelling of old carbon has led to systematically 100–300 yr too old radiocarbon ages for the Mediterranean region. Similarly, the prehistoric tree-ring record produced over 3 decades by the Aegean Dendrochronology Project is shown to provide robust, well-replicated data, contrary to a recent unfounded assertion. 14C and dendrochro...
The distinction is drawn in this paper between true dendrochronological studies (using crossdating) and studies using tree-ring counts to age trees or date events. The advantages of the former approach are emphasized. We summarize the main methods used in dendrochronology, concentrating on new approaches and techniques important in the New Zealand context, present a review of recent dendrochron...
Barry, Devin, "Refining dendrochronology to evaluate the relationship between age and diameter for dominant riparian trees in the Redwood Creek watershed" (2014). Master's Projects. Paper 27.
The Giant Sequoia played several crucial roles in the founding of the modern science of tree -ring dating. These included at least two central theoretical constructs and at least two minor ones; however, historical studies of dendrochronology are actively continuing and this list is expected to expand. Second only to the importance of the ponderosa pine (Pinus ponderosa) in the earliest days of...
