Arctic LTER 1988: del 13C and del 15N ratios measurement for Eriophorum, Carex and lichen species in water tracks at Toolik and Imnavait Creek

del 13C and del 15N ratios were measured for plant and lichen in watertracks in the Toolik Lake drainage and the east facing slope of the Imnavait Creek area. Sampling locations for each species for a specific date were chosen across an elevation gradient starting from the lakeside and leading to ridge crest. The vegetation was dried and analyzed for stable isotopes.
