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 […]

Comparing Results of High and Low Frequency Measurements of Greenhouse Gas Fluxes

Comparing Results of High and Low Frequency Measurements of Greenhouse Gas Fluxes

The emission of greenhouse gasses from soils is caused by dynamic factors such as temperature and moisture. These two factors are also influenced by a multitude of external factors such as diel cycles, land management, wetting/drying events and seasonality; which all lead to a high level of variability in greenhouse gasses emitted (Savage et al., […]

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.” […]

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) […]

AGU 2016

AGU 2016

AGU 2016 HIGHLIGHTS  With a poster in one hand and coffee in the other, four of us from Eosense hopped on a flight to San Francisco, California in the wee hours of the morning on Sunday December 11, 2016.   We were among 25,000 other eager scientists heading to the 2016 American Geophysical Union Meeting (AGU16).  While […]

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 […]

Leave No Flux Undetected Webinar Recap

Leave No Flux Undetected Webinar Recap

Flux Webinar! Last week, Dr. Nick (Nick Nickerson, our chief scientist) co-presented a webinar with Dr. Jesper Christiansen (University of Copenhagen) and Dr. Nabil Saad (Picarro) on all things soil flux! Dr. Christiansen discussed his research on comparing gas flux measurements between static chambers and cavity ring-down spectroscopy (CRDS), or discrete versus continuous flux measurements, respectively. […]
