Abstract: This file contains total numbers of the 22 different types of critters (depending on species, size, maturity, or all three) caught from the two drift distance experiments on the Kuparuk River in 1989. One experiment was on 7 July 1989 at the -500m station, the other was on 10 July 1989 at the 1.7km station.

Organisms studied

Drift samples were taken at
2m, 4m, 8m, 16m, and 32m distances downstream from an arbitrary
point in the river. After those samples were retrieved and
prepared for storage, a very large Nitex net was positioned at
the "arbitrary" point and all invertevrate drift flow was
stopped. Now, a new set of 2m, 4m, 8m, 16m, and 32m drift
distances were taken downstream from the net. The data file
calls these samples "2m before, 2m after, ...".
