Using a novel approach to precisely measure the sedimentation velocity of a (bio)chemical sediment: cyanobacteria-ferrihydrite aggregates
DownloadFall 2020
Banded iron formations (BIF) are iron-rich (~20-40% Fe), siliceous (~40-50% SiO2), and organic-lean (<0.5 wt.%) sedimentary deposits that precipitated widely during the late Archean (2.7-2.5 Ga) and Paleoproterozoic (2.5-1.8 Ga). As cyanobacteria evolved, the reaction between dissolved Fe(II) and...

50,000 years of paleoenvironmental change recorded in meteoric waters and coeval paleoecological and cryostratigraphic indicators from the Klondike goldfields, Yukon, Canada
DownloadFall 2015
A 50,000 year record of meteoric water isotopes (δ2H/δ18O) and paleoenvironmental conditions is presented from syngenetic ice-rich permafrost and macrofossils from eight sites in the Klondike area of central Yukon. Four sedimentary units are recognized based on cryostratigraphy, paleoecological...

The Maritimes Basin is a sedimentary basin covering onshore and offshore Atlantic Canada with late Paleozoic strata. The basin comprises a series of partially-connected and isolated fault-bounded subbasins trending generally northeast. Two subbasins are chosen for detailed analysis: the...

Clay minerals are ubiquitous at the Earth’s surface and they impart a significant influence on numerous geochemical cycles due to their high surface reactivity. Aqueous pH and ionic strength (hereafter IS) are two major factors that affect clay surface reactivity and subsequently govern trace...

Assessing Ecosystem Productivity Through the Integration of Micrometeorology and Optical Remote Sensing
DownloadSpring 2020
The main goal of this thesis is to contribute to the growing body of scientific work by exploring mechanisms of ecosystem productivity through the integration of remote sensing and micrometeorological data. This was done throughout by (i) identifying the environmental mechanisms affecting...

Crowdsourcing Edmonton's Ribbon of Green: A Case Study of Neogeography in Edmonton's River Valley
DownloadFall 2012
Public Participation Geographic Information Systems (PPGIS) has defined a process to support public expression of place-based knowledge. The central weakness of this approach stems from a lack of collaboration support for groups of citizens. Recent GeoWeb advances are challenging PPGIS in this...

Time lapse imagery, an audio recorder and geophones were used to detect iceberg calving events on the Belcher Glacier, Devon Island, in the Canadian High Arctic, in order to identify the major controls on the rate and style of calving. Eleven calving events were identified between June 4th and...

This thesis examines the Housing First (HF) approach to ending homelessness in Alberta, with a focus on how it has been constrained by shortages of affordable housing. It reports on qualitative multiple case study research centred on three cities that have adopted the Ten Year Plan to End...
