Finlay Measurement type: Total ring width Reference: Daniel E. Ackerman, Daniel Griffin, Sarah E. Hobbie, Kelly Popham, Erin Jones, Jacques C. Finlay. 2018. Uniform shrub growth response to June temperature across the North Slope of Alaska. Environmental Research Letters, Vol. 13 (4) 44013. DOI: 10.1088/1748-9326/aab326 Notes: Measurements in raw ring width (units = 0.01 mm). Samples were collected during the 2016 growing season, so the 2016 ring only represents partial growth for that year.
