A new article by researchers at the WTRL describing a bit about the history of tree-ring dating in Ohio is now out in
The Ohio Woodland Journal. A pdf can be found here.
WTRL is Involved in a New Study on Cosmic Events
The Wooster Tree Ring Lab is part of the international tree-ring community, that investigated the global extent and seasonal timing of the rapid increase in atmospheric 14C concentrations from the two largest cosmogenic events in 774 and 993 CE. The initiative named “COSMIC” is lead by Ulf Büntgen (Cambridge University), Lukas Wacker, and J. Diego Galván (Swiss Federal Research Institute WSL) and measured these two cosmogenic events in 44 of the world’s longest tree-ring chronologies. These events are now key marker years and a powerful dating tool. The study was published in Nature Communication and can be found here.
New Publication Detects Cosmic Events in Tree Rings Worldwide
A recent publication that includes the Wooster Tree Ring Lab was published in Nature Communications. See this press release from Cambridge University who lead the effort. 
A Field Blog from A Recent National Geographic Grant
Results of fieldwork in Glacier Bay National Park and Preserve by collaborators from Lamont-Doherty Earth Observatory and University of Alaska – Fairbanks are described here in this excellent blog. This narrative is written by scientist, author and collaborator on the project Lauren Oakes. Lauren is also author of a forthcoming book on Alaska Cedar Decline and Climate.
Tree Corps visits the WTRL
Community Forestry group and Tree Corps – a new program run out of the Holden Arboretum visited the Tree Ring Lab to learn a bit about tree-sampling and the information contained in the tree records.
Coring a white oak that is slated for removal – we learned a lot from the group. For example, Volcano munching was a topic of conversation a concept we which were not aware.
More coring – Nick then took the group to the wood shop and lab.
Mounting the cores – we look forward to working with the group next year. The Tree Corp Program in its inaugural year seemed a major success – congratulations.
