Kahmark, K., N. Millar, and G. P. Robertson. 2020. Static chamber method for measuring greenhouse gas fluxes. KBS LTER Special Publication. Zenodo, http://doi.org/10.5281/zenodo.4630396..
This protocol covers the design, construction, deployment, and gas sampling procedures for the static (closed cover) stainless steel chambers used to measure soil greenhouse gas (GHG) fluxes at Michigan State University’s W.K. Kellogg Biological Station (KBS) in southwest Michigan. The sampling procedure is appropriate for soil nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) fluxes. Detailed instructions on the design and construction of our cylindrical static chamber are covered in part one of this document; field deployment and gas sampling procedures are covered in part two.
Many reviews and publications discuss sampling protocols and procedures for determining soil gas fluxes using various chamber designs and systems, and readers are encouraged to conduct their own review and research on these. The design described herein is compliant with those used by national and international networks. We have successfully used this design (or a close variant) for several decades and share it with the notion that others might benefit from our experience and save some time and effort when deploying their own chambers. Modifications should be straightforward as needs dictate.
