Zinc in Precambrian iron formations: The record, partitioning, diagenetic effects and implications for eukaryotic metallome evolution
DownloadFall 2013
Zinc is amongst the most important trace elements for eukaryotes. Previous work has suggested it to have been at biolimiting concentrations for much of the Precambrian, thereby limiting eukaryotic evolution. Yet, the iron formation (IF) record, a critical proxy for paleomarine conditions, has...

This research used a qualitative community-based case study to examine characteristics of Peavine Métis Settlement that have encouraged residents’ support of wildfire mitigation by the settlement. The specific objectives were to: (1) Identify wildfire risk perceptions at Peavine Métis Settlement,...

Wildfire Evacuation and Emergency Management in Remote First Nations: The Case of Sandy Lake First Nation, Northern Ontario
DownloadSpring 2018
Many decades of successful wildfire suppression in Ontario have resulted in very few losses of life or property. However, the evacuations that often accompany wildfire suppression have continued to disrupt many remote First Nations in the province. Sandy Lake First Nation in Northern Ontario was...

Water and Fine-grained Sediment Assessment in the Capital Region (Edmonton) of the North Saskatchewan River (Canada)
DownloadFall 2022
Purpose: To better understand the behaviors of sediment-associated metals (Cu, Ni, Cd, Mn, Cr, Pb, Fe, Sr, Mo, and Co), an evaluation of physicochemical parameters and metal speciation on suspended and bedload sediment collected from the North Saskatchewan River was conducted in 2018. Sampling...

Volcanic Influence on Atmospheric Sulfur Cycle in 2.7 Ga inferred from Multiple Sulfur Isotope Record of Pyrite Nodules in Black Shales from Nimbus, Western Australia
DownloadSpring 2018
Sulfur isotope compositions of Archean sulfide and sulfate minerals show mass-independent fractionation (S-MIF) signatures, which are characterized by non-zero Î33S and Î36S values. Producing the Archean S-MIF signal requires an O2-free atmosphere where broad-band UV radiation can penetrate to...

We simulated three heavy summer precipitation events in Alberta, Canada, using the Weather Research and Forecasting (WRF) model and compared the output precipitation data with observations to determine model accuracy. Each storm was simulated multiple times, using five different cumulus...
