Identification of taxa, counts, biomass and carbon biomass calculations for phytoplankton and ciliates from artic lakes near Toolik Lake LTER in summer 1998.
Data Set Results
Number of cyanobacteria in Toolik Lake at 1 meter depth during June, July and August 1996. Samples were transported to the Dept. of Fisheries and Oceans in West Vancouver, British Columbia, Canada for analysis.
Number of bacteria (using of DAPI for identifying and counting) in Toolik Lake water column and other lakes sample throught the summer from 1992-2000. There is no data for 2006.
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.
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 - 2017.
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 2021. 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, was taken with a 30 cm diameter plankton net with a 335 um mesh plankton netting. All samples were collected from Toolik Lake and the lakes near the Toolik Field Station, Arctic LTER from 1993-2002. NOTE: In versions pervious to 3 the dates for 1994 and 1995 were WRONG.

We used a fully factorial experiment to test effects of food availability and temperature (7.6, 12.7 and 17.4 degrees C; 50 days) on growth, consumption, respiration, and excretion of slimy sculpin (Cottus cognatus).
We tested effects of temperature (12 and 19.3 degrees C; 27 days) on habitat use, consumption, and growth of slimy sculpin (Cottus cognatus). To measure temperature selection by sculpin, we connected two 5.7 L tanks with a PVC pipe that was passable by sculpin (n = 12 tanks). We heated one side of the tank to 12 °C and the other to 19.3 °C using aquarium heaters.
