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.

Quality Assurance:
[node:field_quality_assurance]
Discharge values were corrected based on updated rating curves. Changed the variable units for conductivity. JAD March2016
Version Changes:
Entered metadata into new metadata form.
Version 3: Data URL was changed to point to the LTERNET Data Access server
Version 4: LTERNET Data Access server proxy changed from das.lternet.edu to metacat.lternet.edu.
Version 5: Added LTERNET Data Access server proxy for Excel files.
Version 6: Edited LTERNET Data Access server proxy for Excel and comma delimited data files. Changed knb to das.
Adjusted discharge measurements based on two rating curves, the Yearly and Composite. See Methods.
