Index of LTER lakes Isotope data files

Isotopes

Isotopic values for carbon and nitrogen in biotic and abiotic samples from lakes. The files containing isotopic values for carbon and nitrogen have is as the seventh and eight characters in the file name.

• 1988-2005_Isotopes_Kling - Composite file describing plant, animal, water, and sediment samples collected at various sites near Toolik Research Station (68 38'N, 149 36'W). Sample site descriptors include an assigned number specific to the file, a number that relates the samples to other samples collected on the same date and time (sortchem), site, date, time, and depth. Samples are identified by type, category, and a short description. Data include isotope values, carbon and nitrogen concentrations, and C:N ratios of samples.

• 88klltis - Carbon and nitrogen stable isotope values for lake trout from 6 different Arctic lakes near Toolik. Also included is fish length, weight, and age.
