Stream discharge, temperature, and conductivity of Toolik Inlet during the 2004 study season. Discharge measurements were taken throughout each season to determine the stage-discharge relationship.

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