Continuous CO2 fluxes in the Cassiope heath

Continuous CO2 fluxes in the Cassiope heath

This blog post was co-authored by Dr. Magnus Lund, Gillian Simpson and Zhila Rashidi (Eosense) BACKGROUND: This summer, researchers from the GeoBasis team at Aarhus University (Denmark) took six eosFD soil CO2 flux sensors to the Zackenberg Research Station in north-eastern Greenland to conduct continuous measurements of soil CO2 fluxes in the Cassiope heath. The […]

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 […]

2017 ICOS Nordic Symposium

2017 ICOS Nordic Symposium

Last week Nick Nickerson, Chief Scientist at Eosense, attended the 1st annual ICOS Nordic Symposium at the Technical University of Denmark in Copenhagen. Over 60 researchers united in Denmark to represent ICOS stations in Norway, Sweden, Denmark and Finland. The latest updates from the ICOS Ocean, Atmosphere and Ecological themes were covered during the three-day conference […]

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 […]

Hot Spots in a Cold Land

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 […]

Peat and Whiskey

Peat and Whiskey

Despite covering only 3% of the Earth’s surface, boreal and subarctic peatlands contain between 270 – 320 Tg of carbon, or about 34-46% of the carbon currently present in atmosphere – dominantly as CO2 (IPCC, 2007). Many of these peatlands began their lives after the last glacial maximum, following the retreat of glaciers from the […]

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 […]
