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 […]

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 […]

Comparing Chambers for Measuring Greenhouse Gas Emissions from Reservoirs

Comparing Chambers for Measuring Greenhouse Gas Emissions from Reservoirs

The action of damming waterways has altered the natural courses of water, resulting in large volumes help up in reservoirs. Previous studies (1, 2) have shown that these reservoirs, along with other inland water sources, are greenhouse gas (GHG) contributors; specifically CO2 and CH4. Precise methods for quantifying reservoir fluxes are not well-documented, though it is […]

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 […]

Running your Picarro GasScouter and eosAC Off-Grid – Part 3

Running your Picarro GasScouter and eosAC Off-Grid – Part 3

Introduction We deployed the GasScouter and eosAC system at Dalhousie University’s Bio-Environmental Engineering Centre (BEEC).  BEEC is a research and demonstration site operated jointly by the Faculty of Agriculture’s Engineering Department and Dalhousie University’s Department of Biological Engineering. We set up the system on a constructed wetland at the BEEC site (normally used for studying […]

Wildfires and the Global Carbon Cycle

Wildfires and the Global Carbon Cycle

This year marks the first time that there have been three consecutive years of record-breaking hottest temperatures on Earth. You don’t need to look any further than a quick google search to find headlines such as “99 Percent Chance 2016 Will Be the Hottest Year on Record” (Scientific American) or “We Just Broke the Record […]
