Salix leaf tissue carbon (C) and nitrogen (N) and isotopes thereof in various plots representing high snow deposition and ambient snow in response to a snow fence. Snow fence was installed in 2003, gas exchange measured in 2012. Deep snow plots had approximately 74 cm of snow covering them. Ambient snow plots were 23 cm deep. Analyzed by IRMS, U. Alaska-Anchorage. Samples were collected six days during 2012. Samples are leaves of Salix arctica, ground to a fine powder using a bead-beater. Known mass of sample was loaded into tin capsules, combusted to CO2, and the gas passed to the mass spec. csv, comma-delimited text. Data columns are: 15N of tissue, 13C of tissue, N content of tissue (%), C content of tissue (%C), species, day of year sample was collected, treatment - +snow or ambient snow depth.
