A model-data comparison of gross primary productivity: Results from the North American Carbon Program site synthesis
Download2012
Anderson, R., Poulter, B., Matamala, R., Lokipitiya, E., Chen, J.M., Verbeeck, H., Davis, K.J., Weng, E., Curtis, P.S., Tonitto, C., Munger, J.W., Ricciuto, D., Chen, J., Gu, L., Humphreys, E., Desai, A.R., Price, D.T., Raczka, B.M., Zhou, X., Peng, C., Torn, M., Hollinger, D.Y., Riley, W.J., Roulet, N., Black, A., Bolstad, P., Baker, I., Thornton, P., Monson, R., Jain, A., Law, B., Gough, C., Margolis, H.A., Dimitrov, D., Grant, R.F., Liu, S., McCaughey, J.H., Hilton, T.W., Sahoo, A., Dietze, M., Schaefer, K., Williams, C., Dragoni, D., Tian, H., Vargas, R., Schwalm, C.R., Richardson, A.D., Oechel, W., Kucharik, C., Barr, A., Altaf Arain, M.
Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against...

Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, Canada
DownloadFall 2010
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...

This report describes the inventory system developed to provide a comprehensive data base for emission of materials to the atmosphere which are judged to be of environmental concern in the AOSERP study area. A detailed evaluation of man-related activities and natural processes within the area was...

Boxed-in: Comparing Algorithms for Box-flight Mass-Balance Greenhouse Gas Flux Measurements from Mineable and In Situ Oil Sands Developments
DownloadSpring 2022
To combat global warming, Canada has committed to reducing greenhouse gases (GHGs) 40-45% below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. GHGs can be measured at a small scale, often using ground measurements which...

Rankin, Robert , Degeling, Alex W., Watt, Clare E.
We introduce a new methodology that allows the construction of wave frequency distributions due to growing incoherent whistler-mode waves in the magnetosphere. The technique combines the equations of geometric optics (i.e., raytracing) with the equation of transfer of radiation in an anisotropic...

Developing a Functional Approach to Assessment of Land Capability: Utilizing Ecosystem Water and Carbon Nutrient Fluxes as Integrated Measures of Reclamation Performance
Download2019-02-14
Straker, Justin R., Carey, Sean K., Petrone, Richard M., Baker, Trevor D., Strilesky, Stacey L.
This report synthesizes over 15 years of research (and 64 site-years of data) on water use, carbon assimilation, and associated ecosystem development on reclaimed oil-sands-mine sites and on non-mine reference sites. A key feature of this research is the use of eddy-covariance methods to make...

This work aims to conduct a techno-economic feasibility analysis of adopting a hybrid approach to hydrogen generation. This includes grey hydrogen sourced from natural gas using Steam Methane Reforming (SMR) and green hydrogen from renewable energy. The key focus is on assessing the environmental...

Development and Applications of an Emissions Micro-Simulation Tool for Transportation Infrastructure Design
DownloadFall 2014
Transportation emissions constitute a significant portion of overall emissions inventories, and contribute to air quality health concerns. Reductions in transportation emissions can be achieved through efficient design of infrastructure, effective policy and regulation, and informed planning...

GHG Emissions from Oil Sands Tailings Ponds: Overview and Modelling Based on Fermentable Substrates
Download2014-11-28
Burkus, Z., Pletcher, S., Wheler, J.
Surface mining of Alberta bitumen is probably the biggest mining operation in the world. It has a significant environmental footprint with about 840 km2 total active footprint in 2012 and 895 km2 in 2013 (Fig 1) (AESRD 2014). Of this area, tailings ponds covered 239.3 km2 in 2013...

Hydrogen as a fuel has the potential to reduce tailpipe carbon dioxide emissions of vehicles to near-zero, while also allowing for the generation of a hydrogen-based economy and lowering humanity's dependence upon oil. Hydrogen-diesel dual fuel combustion, where hydrogen and diesel are combusted...
