Tricks, Tips & Ticks: A spotlight on fieldwork Spring has finally arrived and its brought new life to our gardens and renewed excitement to researchers and fieldworkers around the globe.  Fieldwork can come in many different forms and can range across various disciplines, yet many field-related activities often entail similar preparation and processes regardless of the […]

Carbon Monitoring in Polygonal Ponds

Carbon Monitoring in Polygonal Ponds

This blog post was co-authored by Dr. Julia Boike and her team and Zhila Rashidi (Eosense) Hot Spots in a cold land The Lena River Delta in northern Yakutia, northeast Siberia, Russia, is one of the largest catchment areas (2,430,000 km2) in the Arctic. Polygonal structures, which are common components of arctic Siberian wetlands, are […]

This blog post was co-authored by Dr. Julia Boike and her team (AWI) and Zhila Rashidi (Eosense) Polygonal ponds in Siberian permafrost and their effect on CO2 emissions The Lena River Delta in northern Yakutia, northeast Siberia, Russia, is one of the largest catchment areas (2,430,000 km2) in the Arctic. The bed of Lena Delta […]

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 […]

Greenhouse Gas Emissions from Reservoir Water Surfaces: A New Global Synthesis

Greenhouse Gas Emissions from Reservoir Water Surfaces: A New Global Synthesis

When we think of greenhouse gases, the first thing that comes to mind is the pollution caused by our activities; emissions from cars, factories and landfills. But lower in our consciousness is the impact of a structure typically seen as green and eco-friendly, the reservoir. Dams are helpful, whether it’s for hydropower, flood control, water supplies, […]

Automated Soil Flux Chamber System for Measuring Wetland GHG Emissions.

Automated Soil Flux Chamber System for Measuring Wetland GHG Emissions.

SSSA 2016 Eosense and Picarro Poster: A Portable, Low-Power Cavity Ring-Down Analyzer and Automated Soil Flux Chamber System for Measuring Wetland GHG Emissions. Last week Eosense attended the annual American Society of Agronomy, Crop Science Society of America, Soil Science Society of America’s 2016 Fall Meeting in Phoenix, AZ.  Every year we are amazed with all the […]

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 […]

News Release: Rugged Portability from New Greenhouse Gas Soil Flux System for Field Research

News Release: Rugged Portability from New Greenhouse Gas Soil Flux System for Field Research

December 10, 2015 – Dartmouth, NS, Canada Eosense, a specialist in environmental gas monitoring devices, today announces the new eosMX-P portable recirculating multiplexer alongside of the updated eosAC soil flux chamber. Both devices now offer support for the Los Gatos Research (LGR) Ultraportable Greenhouse Gas Analyzers (http://bit.ly/1IRPS0m). “Eosense’s support for our ultraportable gas analyzers comes […]

Biases of Temporally Sparse Data and Measurement Scheduling on Flux Estimates: Part 3

Part three of the three part series. Here are Part 1 and Part 2. Download the complete article (PDF). EVENT-DRIVEN EMISSIONS Some gas species such as N2O typically follow low emission seasonal baselines with occasional dramatic pulses due to strong rain or treatment effects (Millar and Robertson, 2014; Butterbach-Bahl et al., 2004). Often the non-event sections […]

Biases of Temporally Sparse Data and Measurement Scheduling on Flux Estimates: Part 2

Biases of Temporally Sparse Data and Measurement Scheduling on Flux Estimates: Part 2

Part two of the three part series. Here is Part 1. Periodic Emissions with Events The discussion so far has focused on how measurement scheduling can influence the observation of a periodic and (relatively) predictable flux time-series, driven almost entirely by diurnal temperature variation. We will now look at how these measurement effects can change […]
