Application of Ichnology Towards a Geological Understanding of the Ferron Sandstone in Central UtahDownload
Ichnology has long been used as a tool to aid in environmental interpretation, but has rarely been used as an ethological assessment tool in the Cretaceous Ferron Sandstone of central Utah. This study focuses on using trace fossils with detailed sedimentological analyses to describe continental,...
Zinc in Precambrian iron formations: The record, partitioning, diagenetic effects and implications for eukaryotic metallome evolution
Zinc in Precambrian iron formations: The record, partitioning, diagenetic effects and implications for eukaryotic metallome evolutionDownload
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 OntarioDownload
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...
International law guarantees every person the highest attainable standard of health, and this should include protection from the health risks of environmental tobacco smoke. As knowledge of these risks has increased, there has been an incremental expansion of smoking bans in public space. Since...
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 AustraliaDownload
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...
Tidewater outlet glaciers drain approximately 47% of the ~105,000 km^2 covered by ice caps in the Queen Elizabeth Islands of Nunavut, Canada, suggesting that iceberg discharge may be an important process in the mass balance of these ice caps. Seasonal and inter-annual velocity changes of...
Variations in climatic conditions from the Cayman Islands through stable isotope and element analysis from corals and sediment cores; a 500,000 year recordDownload
The Caribbean region is particularly important to understanding global climate change and feedback systems because the tropics are the primary source of heat and water vapor for the atmosphere. The Caribbean region, however, is a relatively understudied area in terms of tracking climate change...
