Data for: Gas Transfer Velocities Evaluated Using Carbon Dioxide as a Tracer Show High Streamflow to Be a Major Driver of Total CO2 Evasion Flux for a Headwater Stream McDowell, Mollie; Johnson, Mark
This dataset contains direct in-situ measurements and modeled values of stream properties and air temperature of a steep, turbulent headwater stream in southwestern British Columbia, Canada, between November 2016 and June 2017. The dataset is associated with a study of CO2 evasion from experimental stream G-H in the University of British Columbia Malcolm Knapp Research Forest, which estimated gas transfer velocities of CO2 (kCO2) and CO2 evasion using an automated in situ CO2 tracer technique.
McDowellJohnson2018_continuousdata.tab contains continuous half-hourly stream data for the duration of the study period.
McDowellJohnson2018_injectiondata.tab contains averaged values of stream data associated with 38 one-hour injections of CO2.
Continuous data variables: date-time, CO2 concentration, pH, water temperature, electrical conductivity, air temperature, stream discharge, stream depth, water velocity, modeled gas transfer velocity of CO2, modeled gas transfer velocity of CO2 normalized to a Schmidt number of 600, dissolved oxygen concentration
Injection data variables: date-time, stream depth, gas transfer velocity of CO2, gas transfer velocity of CO2 normalized to a Schmidt number of 600, stream discharge, water temperature, water velocity
This work was conducted on the unceded, ancestral territories of the xʷməθkʷəy̓əm (Musqueam) and Katzie peoples.
