The course will cover equipment required, field techniques, how to `choose' study trees, increment core collection and transport, core mounting and sanding, skeleton plotting and crossdating, and the use of computer programs for quality control and chronology development. The first day of the workshop will cover all items through sanding procedures in the morning. The afternoon will be spent in the field collecting cores and beginning core preparation in the lab. The second day of the workshop will be devoted to skeleton plotting and crossdating cores, measuring ring widths, and running COFECHA (a program designed to verify/assist with crossdating accuracy). The final portion of the workshop will consist of running ARSTAN ( a program designed to develop a species/site chronology from the collection of individual cores). Workshop participants will need to bring clothes appropriate for field activities, including sturdy boots and raingear. If you are interested in this workshop let me know.
