Guest Blogger: Lynnsey Delio, The Keck Geology 2025 team has been working in the Wooster dendrochronology lab for the first week of research. The team cored the oak tree in front of Scovel on day 1 for some practice coring. They also made use of the woodshop in Scovel Hall and practiced sanding and mounting cores.

The team has also been working with programs COFECHA and CooRecorder in the computer lab to mark the tree rings on red cedars from Southeast Alaska. They have been working to create an optimized red cedar tree ring series for the area, dating back centuries. This data can be used to compare to other tree ring series and look for climate signals and responses. These climate responses can be analyzed from a global climate perspective to understand the correlation between dendrochronology and global climate phenomena.
To accurately date the cedar cores, the team used cores from previously dated red cedars in Southeast Alaska to correlate them to the undated samples. Some of these previously dated cores included logged trees that were intended for use in totem poles.
