Wildfire risk and response in Jasper National Park, Alberta: Application of an adaptation readiness framework
Download2021-06-23
Halabut, Rechelle, Birchall, S. Jeff
Environmental change associated with warmer temperatures is creating unprecedented conditions in natural regions and ecosystems. In Jasper National Park, Alberta, climate change, historical fire management practices, and the mountain pine beetle infestation are combining to increase the risk of a...

We address the missing analog of vague convergence in the weak-converge large-deviations analogy. Specifically, we introduce the weak Laplace principle and show it implies both the well-known weak LDP and the Laplace principle lower bound. Both the weak LDP and weak Laplace principle hold in...

Thinning Sea Ice and Thawing Permafrost: Climate Change Adaptation Planning in Nome, Alaska
Download2019-07-02
Birchall, Jeff S., Bonnett, Nicole
Climate change is among the most critical challenges facing local government decision-makers in the north. Yet while risk is clear, with climate impacts occurring there more rapidly than many regions on Earth, integrated policy and planning for climate adaptation often remains a low priority for...

Bonnett, Nicole, Birchall, S. Jeff
This study examines extent and quality of climate adaptation integration within strategic plans of local governments in British Columbia, Canada. Strategic plans (n=39) were assessed using plan content analysis in order to understand whether regional planning leads to adaptation action by...

The Built Environment in a Winter Climate: Improving University Campus Design for Student Wellbeing
Download2021-07-01
McDonald-Yale, Eden, Birchall, S. Jeff
Like urban environments, the campus built environment can influence general wellbeing of students. At the same time, campuses are their own unique form and need to be analyzed in their own way. This study identifies elements of the campus built environment that contribute to student wellbeing,...

Social vulnerability and climate change adaptation: The critical importance of moving beyond technocratic policy approaches
Download2021-10-01
Kehler, Sarah, Birchall, S. Jeff
Planning policy can play a key role in effective, equitable climate change adaptation; however, its capacity remains undermined by technocratic approaches reliant on hard measures, discounting significant research on addressing sources of social vulnerability for successful adaptation policy. Not...

Rhenium-osmium systematics and major and trace element chemistry of cobaltite (CoAsS): Evidence for Late Mesoproterozoic sediment-hosted Co-Cu sulfide mineralization with Grenvillian and Cretaceous remobilization in the Idaho Cobalt Belt, Belt-Purcell Basin, USA
Download2019-01-07
NJ Saintilan, RA Creaser, AA Bookstrom
We report the first study of the Re-Os systematics of cobaltite (CoAsS) using disseminated andmassively mineralized samples from two breccia-type and two stratabound deposits from the Co-Cu-Au Idaho Cobalt Belt, Lehmi Sub-basin to the Belt-Purcell Basin, Idaho, USA. Using a 185Re+190Os spike...

Recommendations for offline combustion-based nitrogen isotopic analysis of silicate minerals and rocks
Download2021-03-01
Li, Long, Li, Kan, Li, Yingzhou, Du, Yifan, Labbe, Mark
Rationale Due to isotope fractionations during partial nitrogen release from minerals and rocks, the complete extraction of nitrogen for analysis is crucial to ensure high-quality nitrogen isotopic data. However, the appropriate nitrogen extraction conditions (e.g. temperature, duration) have not...

Re-Os SYSTEMATICS OF LOELLINGITE AND ARSENOPYRITE IN GRANULITE-FACIES GARNET ROCKS: INSIGHTS INTO THE METAMORPHIC HISTORY AND THERMAL EVOLUTION OF THE BROKEN HILL BLOCK DURING THE EARLY MESOPROTEROZOIC (NEW SOUTH WALES, AUSTRALIA)
Download2019-01-09
NJ Saintilan, RA Creaser, PG Spry
Loellingite and arsenopyrite aggregates occur in spessartine-almandine garnet rocks (garnetite) metamorphosed to granulite facies, which are spatially associated with Pb-Zn-Ag mineralization in the giant Broken Hill deposit, southern Curnamona Province, New South Wales, Australia. Sulfarsenide...

Paleozoic reactivation structures in the Appalachian-Ouachita-Marathon foreland: Far-field deformation across Pangea
Download2017-04-03
Porter, Ryan, Malone, David H., Day, James E., Craddock, John P., Luczaj, John, Konstantinou, Alex, Johnston, Stephen T., Compton, John
The Proterozoic Grenville orogeny (~ 1300–980 Ma) reactivated the Archean-hosted Kapuskasing suture in Laurentia which then propagated west and south initiating the Keweenaw rift (1141–1085 Ma) which closed by thrust shortening at 1060 Ma. Late Proterozoic-Paleozoic sediments were then deformed...
