Methods: 

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.
