TAXONOMIC COVERAGE:
Organisms studied

Methods:	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 submission.) The samples were preserved in ethanol then picked, sorted, counted, and measured in Duluth using a NIKON MICRO-PLAN II digitizing pad. Sampling Description. None
