Abstract: This is Oksrukuyuk Creek drift. The files simply list the length of each insect measured, as well as when and where along the creek it was captured. Only the actual measurements of the insects are listed, for example, if there wasn't a paticular insect found at a replicate at a station, then that station isn't listed either. This file lists captured brachycentrus.

Organisms studied

A 15 minute drift-sampling technique was used to
collect samples at eight (or sometimes nine) different stations (-550m,
-320m, -267m, -136m, (sometimes also 233m), 482m, 1056m, 1370m, and 1800m)
with two replicates at each station. Two different dates were sampled for
drift, the same procedure was used for both dates. The stations were measured
relative to the future site of the new dripper.
The samples were preserved in ethanol then picked, sorted,
counted, and measured in Duluth using a digitizing pad.
