The eosFD is branching out to measure tree stem flux!

Stem Respiration Forests store a lot of carbon both aboveground in vegetation, and belowground in the soil. To implement effective forest management policy, policy makers must understand the forest’s carbon budget, including whether it is a net source or sink. There is currently a good understanding of carbon efflux rates from soils and leaves, but […]

How Similar Should my Soil Respiration Measurements Be? – A Look at Field Site Spatial Variability

How Similar Should my Soil Respiration Measurements Be? – A Look at Field Site Spatial Variability

Introduction Measuring greenhouse gas emissions in natural and controlled ecosystems can be notoriously tricky, both because of spatial heterogeneity and the highly dynamic systems which are responding to drivers (temperature, moisture, sunlight, etc.) on multiple time scales. This often makes direct comparison between measurement locations and across differing flux measurement instruments and methodologies impractical, if […]

Total Greenhouse Gas Exchange from a Beef Cattle Farm Using Direct Whole Farm Measurements

Total Greenhouse Gas Exchange from a Beef Cattle Farm Using Direct Whole Farm Measurements

Many anthropogenic activities are significant sources of greenhouse gasses, however not all emissions are as easy to quantify as the direct burning of fossil fuels (e.g. for transportation or electricity). Other significant sources of greenhouse gasses including agriculture can be harder to quantify due to the increased number of variables involved. In Canada, this sector […]

Testing Novel CO2 Soil Flux Measuring Equipment and its Use in Monitoring Permafrost Activity

Testing Novel CO2 Soil Flux Measuring Equipment and its Use in Monitoring Permafrost Activity

The International Symposium on The Cryosphere in a Changing Climate was hosted by Victoria University of Wellington from February 12 to 17, 2017, in Wellington, New Zealand. Ronald Layden from the Aurora Research Institute at Aurora College in Yellowknife, NT attended and presented his poster on “Testing Novel CO2 Soil Flux Measuring Equipment and its Use in Monitoring Permafrost Activity.” […]

Closed Chamber Systems for Continued Research of Greenhouse Gas Fluxes from Permafrost Zones

Closed Chamber Systems for Continued Research of Greenhouse Gas Fluxes from Permafrost Zones

Understanding greenhouse gas emissions from stored organic carbon is an increasingly important area in gas flux science. Melt of permafrost layers, caused by rising global temperatures, threatens to contribute more to atmospheric CO2 concentrations than previously thought. These large permafrost melt driven emissions of greenhouse gases also have the potential to cause accelerated global warming […]

Heat Wave Effects on Greenhouse Gas Flux in Shallow Lakes

Heat Wave Effects on Greenhouse Gas Flux in Shallow Lakes

Freshwater systems are an important component on global carbon and nutrient cycles; having a disproportionally large impact given their small global surface area (Davidson et al., 2015). Generally, inland aquatic systems are considered to be carbon sources on an annual basis, however, their output can vary significantly (Tangen et al., 2016). The size of water […]

Reduced Tillage Practices: Are they really a “climate-friendly” alternative?

Reduced Tillage Practices: Are they really a “climate-friendly” alternative?

Conservation Tillage: The Search for Sustainable Agriculture With both the global population and temperatures on the rise, there is an ever-growing need for the development of ways to help feed the masses while reducing greenhouse gas emissions. Conservation tillage appeared to be the answer to both, however, a recent study by Lognoul et al. (2016) […]

Extensive Green Roof Carbon Dioxide and Methane Fluxes

Extensive Green Roof Carbon Dioxide and Methane Fluxes

Recap On October 6th, Eosense and the Lundholm Lab set up 4 eosAC automated soil flux chambers with a Los Gatos Research Ultraportable Greenhouse Gas Analyzer (UGGA) on the Atrium Green Roof at Saint Marys University in Halifax, Nova Scotia. Using the eosAC/UGGA system, carbon dioxide and methane fluxes were monitored during a week-long period […]
