Description:

Please see the associated paper for detailed methods: Distinct concentration-discharge dynamics in temperate streams and rivers: CO2 exhibits chemostasis while CH4 exhibits source limitation due to temperature control in Limnology and Oceanography by Kelly S. Aho, Jennifer H. Fair, Jacob D. Hosen, Ethan D. Kyzivat, Laura A. Logozzo, Gerard Rocher-Ros, Lisa C. Weber, Bryan Yoon, and Peter A. Raymond.

Briefly, dissolved gas samples were collected via headspace equilibration method: 80 ml of water and 20 ml of N2 gas were equilibrated in a 140-ml syringe for 2 min and headspace samples were analyzed on a Shimadzu GC2014 or an SRI Model 8610C GC. The post processing calculations are available at https://github.com/kellyaho/headspace_calcs.git.
