Functional morphology is an important tool for paleoecology. However, functional interpretations which are based on tenuous logic without a proper test or which rely on circular reasoning can be problematic. Biomechanical tests can help to provide structured and absolute assessments of...

This thesis investigates the processes and evolution of the sub-oceanic lithospheric mantle beneath the Southwest (SW) Pacific region via two direct sampling methods: 1) basalt-hosted peridotite xenoliths erupted by volcanic eruptions from Koro Island in eastern Fiji, and 2) tectonically exposed...

Jurassic-Cretaceous rifting within Arctic North America that eventually resulted in the formation of the Arctic Ocean greatly affected deposition within nearshore terrestrial basins in surrounding areas, such as the Brooks-Mackenzie Basin and the Sverdrup Basin. In this thesis, measured...

Diamonds, due to their inert and robust nature, encapsulate and preserve minerals, recording the mantle substrate in which they form. Forming in the subcontinental lithospheric mantle over a protracted period, diamonds provide snapshots of craton formation and mantle evolution over much of...

The Greenland Ice Sheet (GrIS) is the largest freshwater reservoir in the Northern Hemisphere and continues to discharge large amounts of meltwater and icebergs into the ocean. The ice sheet has the potential to raise the sea-level by over 7 metres and impact ocean circulations. Greenland’s...

Lianas are woody thick-stemmed climbers that use host trees to reach the forest canopy. Studies have shown a remarkable increase in liana abundance in the last two decades, while others have shown that liana abundance is associated with detrimental effects on forest dynamics. Liana abundance...

Little is known about how and why Indigenous peoples are engaged in wildland fire management particularly in the areas of wildfire prevention, mitigation, preparedness, response, and recovery abilities in the event of a threatening wildfire. This qualitative study explored how and why Indigenous...

Increased mass loss from the Canadian Arctic ice caps is associated with regional increases in the summer mean glacier surface temperature and the annual number of melt days. As a result of these changes , snow and ice melt are likely to occur at higher elevations and become more widespread,...

The ~143 martian meteorites serve as the only rock samples from Mars that are presently available for study in a laboratory setting. These predominantly igneous samples are sourced from the near-surface units adjacent to craters formed during random, hypervelocity impacts of asteroids on the...

The increased development of unconventional resources recovery has dramatically changed the global energy landscape over the past two decades. Hydraulic fracturing combined with horizontal drilling, a key technology in recovering these resources, requires large freshwater volumes to fracture the...
