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, deployed near bottom opf stream, 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 1996-2013) for Toolik Inlet to solve for stream discharge.
Temperature data were rounded to nearest tenth of a degC, in accordance with sensor manufacturer's specifications
Conductivity data were rounded to nearest uS/cm, in accordance with sensor manufacturer's specifications
Discharge data were rounded to 3 significant digits

Version Changes:
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
2 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.
Sites sampled.
