Dr. Mark Abbott and his graduate students Cole and Adeel visited the Wooster Tree Ring Lab with portions of white oak beams from a historic cabin in Pittsburgh. The mission was to tree ring date the outer ring of the samples to determine which calendar year the timber was cut for the structure. Here the Pitt team in the sample prep. lab with the two samples where they polished them for analysis.
Nick Wiesenberg oversaw the dating, which started with a tour in the west wing of the Wooster Tree Ring Lab.
Adeel measured one of the samples – understandably he is amazed with the anatomy of the white oak rings.
Cole measured the other sample measuring ring widths from the screen using CooRecorder. The Pitt group are exports in lake core analysis and both Adeel and Cole are analyzing lake varves, they are also thinking about using this measuring setup for varve analyses (see below).
Nick takes the controls and analyzes the measurement data against our tree-ring database and reveals the date of cutting for the cabin.
The crossdating with our master series shows that the outer ring of the samples were both 1834, at least for the two samples both were cut in the
