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 […]

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 […]

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, […]

eosFD chambers now measuring soil CO2 flux at Howland Forest

eosFD chambers now measuring soil CO<sub>2</sub> flux at Howland Forest

A set of eosFD chambers are enjoying their new home as part of a Mitacs-funded graduate internship, co-installed alongside existing automated soil respiration chambers at the Howland Forest in central Maine (See insert for more details about the amazing Howland Forest). Two weeks ago, I headed down to the forest, a tidy 7.5 hour drive […]
