Diel, seasonal, and inter-annual variation in carbon dioxide effluxes from lakes and reservoirs
Accounting for temporal changes in carbon dioxide (CO 2 ) effluxes from freshwaters remains a challenge for global and regional carbon budgets. Here, we synthesize 171 site-months of flux measurements of CO 2 based on the eddy covariance method from 13 lakes and reservoirs in the Northern Hemisphere, and quantify dynamics at multiple temporal scales. We found pronounced sub-annual variability in CO 2 flux at all sites. By accounting for diel vari…
The biophysical climate mitigation potential of boreal peatlands during the growing season
Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland conservation and restoration. To assess the bioph…
Prompt active restoration of peatlands substantially reduces climate impact
Restoration of peatlands after peat extraction could be a benefit to the climate system. However a multi-year ecosystem-scale assessment of net carbon (C) sequestration is needed. We investigate the climate impact of active peatland restoration (rewetting and revegetating) using a chronosequence of C gas exchange measurements across post-extraction Canadian peatlands. An atmospheric perturbation model computed the instantaneous change in radiativ…
Carbon dioxide and methane exchange at a cool-temperate freshwater marsh
Freshwater marshes have been shown to be strong sinks for carbon dioxide (CO _2 ) on an annual basis relative to other wetland types; however it is likely that these ecosystems are also strong emitters of methane (CH _4 ), reducing their carbon (C) sequestration potential. Multiyear C balances in these ecosystems are necessary therefore to determine their contribution to the global C cycle. Despite this, the number of multiyear studies in marshes…
Can boreal peatlands with pools be net sinks for CO 2
Peatland open-water pools, a common feature on temperate to subarctic peatlands, are sources of carbon (C) to the atmosphere but their contribution to the net ecosystem carbon dioxide exchange (NEE-CO _2 ) is poorly known; there is a question as to whether peatlands with pools are smaller sinks of atmospheric C, or even C-neutral, compared to other peatlands. We present growing season NEE-CO _2 measurements using the eddy covariance technique in …
Empirical Post Keynesian Economics
Peer and self assessment of group work
In order to manage increased enrolment in a third‐year course in microclimatology, group work was introduced with seminar presentations and term papers. A peer‐ and self‐assessment strategy was developed that provided individual group members the opportunity to appraise their own and partners’ performance. The course instructor worked with an adviser from the university's educational development unit throughout the term to develop and critique th…
