RESEARCH LOCATION:
Geographic Description	Toolik Lake (Site code 100) was sampled weekly at the mainstation situated in about 20 m of water in the southern part of the lake. (9) EXPERIMENTAL DESIGNS AND METHODS: The samples were taken with a 30 cm diameter plankton net with 335 um mesh plankton netting. In almost all cases replicate vertical tows were taken with the length varying on the depth of the lake. The samples were preserved in an alcohol/formalin solution and stored in 250 ml Nalgene bottles. The samples were counted by taking a subsample of 1 or 02 mL from the bottle and enumerating all zooplankton by species using a M-5 stereomicroscope. All samples were counted and enumerated by Suzanne Baines and Cody Johnson
