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.
Zooplankton density,were taken with a 30 cm diameter plankton net with 156 um mesh plankton netting, for all samples collected from Toolik Lake and lakes near the Toolik Field Station, Arctic LTER from 2003 - 2010
This file contains the fish number, recap number, species, lengths, weights, sex and a list of tissues sampled of fish captured in lakes near the Toolik Lake Arctic LTER site during summers from 1986 to present. The file also contains information from gill-netted fish (if any), sacrificed fish, and accidentally killed fish. All dead fish are included, and if their stomachs and otoliths were taken, that is noted also.
Zooplankton density in number per liter for all samples collected from arctic lakes near Toolik Lake Field Station (Arctic LTER) in summer from 1983 to 1992 (inclusive).
NOTE: The dates for 1992 are WRONG in versions 1 and 2.
The original dates were entered in several date formats which resulted in conversion errors.
