Organisms studied

A rock-scrubbing technique was used to collect bottom samples at six different stations (-400m, -320m,
-200m, -100m, 727m, and 950m) with three replicates at each station in the Oksrukuyik River. The
stations are measured relative to the future placement of the New Oxy Dripper. One sampling date is
represented here (10 July 1989). (This is the first date analyzed, others are top priority at the time of this
The samples were preserved in ethanol then picked, sorted, counted, and measured in Duluth using a
NIKON MICRO-PLAN II digitizing pad.
