A practical introduction to soil greenhouse gas flux measurement. Covers what flux means, how CO2, CH4, and N2O are produced in soil, gas transport mechanisms, chamber methods, and the basics of flux calculation.

Abstract: Trace gas fluxes, including carbon dioxide, methane, and nitrous oxide, are key components of ecosystem greenhouse gas budgets. Accurate and cross comparable measurement of these fluxes at soil and canopy scales has often been constrained by the lack of standardized systems, historically r...

We are a Canadian company built by scientists who understand the value of good data. It’s our mission to develop gas monitoring instruments that enable scientists and engineers to measure environmental gas flux and concentration - wherever their field sites may be. With equipment deployed all over the world, from the rain-forests of Puerto Rico to the dry valleys of Antarctica, we’re helping researchers extend the reach of their investigations.

Introduction Rice is a staple crop throughout much of the world, and its cultivation in flooded paddies contributes significant amounts of methane to the global budget. However, the exact magnitude of this contribution is still uncertain, necessitating ongoing improvement and development of measurement techniques. This, paired with advancements in the ways rice is grown, represents […]

Why a Base Extension? Automated chamber systems enable researchers to examine and understand temporal and spatial variation in GHG fluxes and their driving mechanisms. However, every field site and investigation is different and no single chamber design is perfectly suited to all studies.  That’s why Eosense developed two base extension options for our eosAC-LT/LO chambers […]
