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

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 (<i>k</i>_CO2) and CO₂ evasion using an automated in situ CO₂ tracer technique.

<i>McDowellJohnson2018_continuousdata.tab</i> contains continuous half-hourly stream data for the duration of the study period.

<i>McDowellJohnson2018_injectiondata.tab</i> contains averaged values of stream data associated with 38 one-hour injections of CO₂.

<b>Continuous data variables:</b> 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

<b>Injection data variables:</b> 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.
