For discharge measurement protocol, see the Land-Water protocol accessible from the Land-Water mainpage on the Arctic LTER web page or at http://www-personal.umich.edu/~gwk and clicking on the protocol link at the bottom of the page.
Water level was recorded continuously with with a Stevens PGIII Pulse Generator connected to a Campbell Scientific CR510 datalogger. Additionally, we deployed a Campbell Scientific Model 247 Conductivity (EC) and Temperature probe which also recorded to the CR510.
Discharge measurements were taken throughout each season to determine the stage-discharge relationship. When the stage heights exceed our range from the study year's rating curve, we apply a standardized composite rating curve (from 1991-2006) for Toolik Inlet to solve for stream discharge.

Version Changes:
Adjusted discharge measurements based on two rating curves, the Yearly and Composite. See Methods.
Version 2: Updated units to current standards. Updated metadata form to newer version (without site sheet). CH 4Feb2013 Updated to newer metadata form (with sites sheet) Ch March 2013.
Version 3: Checked keywords against the LTER network preferred list and replaced non-preferred terms. Jim L 15Jan14
Changed Distrubution URL since the LTER network DAS system is being discontinued. JimL 9Apr2015
February 2016. Changed file with Dataset ID *.01 to Dataset ID *.02. The discharge measurements were corrected based on updated rating curves, removed the variable "stage height" because this is a relative measure not comparable across years, rounded Temp, cond, and Discharge. See Methods.
