Stream discharge, temperature, and conductivity of Toolik Inlet during the 2010, 2012, 2013 study season. Data from 2011 still has problems and will be added later.

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 tenth of uS/cm, in accordance with sensor manufacturer's specifications
Discharge data were rounded to 3 significant digits
