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.
Decadal file describing the physical/chemical values recorded at various lakes near Toolik Research Station during summers from 1990 to 1999. Sample site descriptors include site, date, time, depth. Depth profiles of physical measures collected in situ with Hydrolab Datasonde in the field include temperature, conductivity, pH, dissolved oxygen in both percent saturation and mg/l, SCUFA chlorophyll-a values in both volts and µg/l, and PAR.
Decadal file describing the chlorophyll a and primary production in various lakes near Toolik Research Station (68 38'N, 149 36'W) during summers from 1990 to 1999. Sample site descriptors include an assigned number (sortchem), site, date of analysis (incubation), time, depth and rates of primary production. The amount of chlorophyll a and pheophytin were also measured.
Decadal file describing the water chemistry in various lakes near Toolik Research Station (68 38'N, 149 36'W) during summers from 1990 to 1999. Chemical analyses were conducted on samples from various depths in the sample lakes either once, or multiple times during the spring, summer and fall months (May to September).
