Running your Picarro GasScouter and eosAC Off-Grid – Part 1

Running your Picarro GasScouter and eosAC Off-Grid – Part 1

Running your Picarro GasScouter and eosAC Off-Grid – Part 1 Introduction to the Picarro Gas Scouter and eosAC Automated Soil Flux Chambers Gas analyzers have become increasingly more precise over the past 10 years with the adoption of laser-based sources and ultra-long path length optical cells. However, usually this has been at the cost of power […]

Greetings from ESA 2016 in sunny Florida!

Greetings from ESA 2016 in sunny Florida!

I headed down to sunny Ft. Lauderdale last week in blistering heat, poster tube in hand, excited to attend the 101st Ecological Society of America conference. The theme, Novel Ecosystems in the Anthropocene, is critical to understand at this point in human history. Overall, the sessions focused on the impacts of human activity on ecosystems, […]

Hedgerow Management as a Viable GHG Mitigation Strategy: Does it work?

Hedgerow Management as a Viable GHG Mitigation Strategy: Does it work?

Hedgerow Management Strategies as Viable GHG Mitigation: Does it work? Hedgerows have been important parts of managed farmlands for centuries in Europe, traditionally used to mark land boundaries, preventing soil loss from wind erosion, and used for fuels if managed properly. Today they still offer these same benefits, however their ecological importance is highlighted as […]

Infrared Gas Analyzers vs. Gas Chromatography in Coastal Ecosystems

Infrared Gas Analyzers vs. Gas Chromatography in Coastal Ecosystems

Out with the old, in with the new? A recent study by Brannon and colleagues (2016) out of the Moseman-Valtierra Lab aimed to compare ye olde gas chromatograph (Shimadzu GC-2014) with the newer technologies of a cavity ring down spectroscopy (CRDS) gas analyzer (Picarro, Model G2508) and an off-axis integrated cavity output spectroscopy (OA-ICOS) analyzer […]

Is your seal affecting your chamber closure and flux measurements?

Is your seal affecting your chamber closure and flux measurements?

Is your chamber seal affecting your flux measurements? Manual and automated chambers provide invaluable data about greenhouse gas fluxes that can be used for applications ranging from understanding basic biological processes to evaluating feedbacks and impacts of climate change. As greenhouse gas analyzers become more precise and offer highly resolved temporal data, methods used for […]

Combining Multiple Measurement Techniques

Combining Multiple Measurement Techniques

Combining Multiple Techniques: Benefits of Unified Measurements Researchers are no strangers to using multiple measurement techniques to cover the many scales of spatial and temporal variation experienced in the field. On the Eosense blog, we’ve surveyed a number of publications by scientists who need multiple measurement techniques to answer their core research questions, ranging from […]

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. […]

Powering the eosAC-MX and Gas Analyzer Using a Generator

Powering the eosAC-MX and Gas Analyzer Using a Generator

Considerations for Seting Up a Generator to Power Your Gas Flux System Eosense’s eosAC and eosMX/MX-P are designed to be deployed in remote and challenging environments alongside Picarro and LGR analyzers. As a result, many of these field deployments won’t allow users the convenience of grid power, and may be situated in areas unsuitable or difficult […]

Spatio-temporal variability of N2O

Spatio-temporal variability of N<sub>2</sub>O

Spatio-temporal variability of N2O: Spatial, temporal and methodological biases Soil flux of nitrous oxide (N2O) is unpredictable to measure under natural circumstances and becomes even more difficult when looking at agricultural sites. One reason for this is the temporal uncertainty associated with agricultural soils where fertilizer application, animal voiding and intense rainfall can increase fluxes […]

Minimum Detectable (Soil) Flux: Part 3

Minimum Detectable (Soil) Flux: Part 3

Part three of the three part series. Here are Part 1 and Part 2. Download the complete article (PDF). Extending minimum detectable flux to high-frequency measurements As discussed previously, the MDF metric provides a useful experimental design and quality control criteria for flux measurements. However, it can be extended from the original formulation to show […]
