Gans Creek, Missouri - MO049 Additional Site Information Steven Voelker Cores Stored at: Oregon State University Reference: Voelker, Steven L., Paul-Emile Noirot-Cosson, Michael C. Stambaugh, Erin R. McMurry, Frederick C. Meinzer, Barbara Lachenbruch, and Richard P. Guyette 2012. Spring temperature responses of oaks are synchronous with North Atlantic conditions during the last deglaciation. Ecological Monographs 82:169-187 Notes: These cores were taken to measure growth rates, wood anatomy and stable isotope measurements from dominant and co-dominant trees across tree ages. Two cores were taken for each tree but in most cases only one was measured for ring-widths. The other was destructively sampled for stable isotope measurements.
