RESEARCH LOCATION:
Geographic Description	Kuparuk River. Solute injection was made under the Dalton highway bridge (+1.610km). Samples were collected at +2.475km and +5.550km.

TAXONOMIC COVERAGE:
Organisms studied

Methods:	The channel locations were instrumented with Orion bromide selective electrodes to monitor instream bromide concentrations and guide the collection of physical samples. Physical samples were collected at irregular time intervals weighted to cover the rising and falling limbs more intensively than other time periods. Upon return, the physical samples were analyzed by HPLC on a Dionex AS4A Anion column with detection of 10 ug/L. The table below contains the solute injection parameters. Injection Start: 0 minutes Injection End: 353 minutes Stock Concentration: 439874.85 mg/L Injection Rate: 401 mL/min Notes: There was a loss of power to the injecting pump mid-way through the addition. All distances are relative to the established river markings. (11) VARIABLE DESCRIPTIONS: Precis. Coded?
