Kuparuk Upland, Alaska - AK152 Additional Site Information D. Ackerman D. Griffin S.E. Hobbie J.C. Finlay Measurement type: Total ring width Reference: Daniel Ackerman, Daniel Griffin, Sarah E. Hobbie and Jacques C. Finlay. 2017. Arctic shrub growth trajectories differ across soil moisture levels. Global Change Biology, DOI: 10.1111/gcb.13677 Notes: Each sample represents mean of 4 radii measured throughout the stem of the individual. Measurements in raw ring width (units = 0.01 mm). Samples were collected during the 2015 growing season, so the 2015 ring only represents partial growth for that year.
