Laboratory of Tree Ring Research Archive

Whilst visiting Laboratory of Tree Ring Research at the University of Arizona last week, Garry Armstrong visited the LTTR’s archive, home to the world’s largest and most diverse collection of tree-ring specimens, available to dendrochronology researchers internationally. Garry was accompanied by Steve Guilfoyle from Isotopx and Lucas Smith from Teledyne Photon Machines, who had also attended the Winter Plasma Conference in Tuscon.

Housed in the dedicated Tree-Ring Archive Building adjoining the Bryant Bannister Tree-Ring Building, the repository has two environmentally controlled floors containing 4.4km of shelving as well as a separate curation work area. The repository is the only facility for the storage of tree-ring specimens with a formal federal repository agreement, and contains many samples from federally protected lands.
