The McMurdo Dry Valleys (MDV) are a frigid, hyperarid desert of Antarctica with a landscape dominated by ice-rich permafrost. This research focuses on using two ice-rich permafrost cores collected from the MDV to study chemical processes (Beacon Valley core) and the timing of MD…
Glacial isostatic adjustment (GIA) is the ongoing response of the viscoelastic solid Earth, oceans and the gravitational field to the previous burden of the ice loads. The Earth’s surface was once covered with massive ice sheets, and melting of these ice sheets is still reshapin…
This interdisciplinary thesis aims to elucidate processes responsible for sea-level changes during climate events spanning the Miocene to present day, using the tools of numerical geodynamics and theoretical geophysics. Understanding critical events in Earth’s climate history pr…
Postglacial rivers are part of the relatively young low-relief landscape system left behind by glaciers. Over time, postglacial rivers are susceptible to both minor and major channel planform changes as the Earth and its newly exposed rivers adjust to new isostatic and geomorphi…
Glaciers are an integral part of polar and alpine landscapes, providing water, inorganic, and organic material subsidies to downstream ecosystems. These subsides regulate downstream temperature, streamflow, and sediment supplies. Warming in high altitude and high latitude enviro…
Iceberg calving is an efficient ablation process which introduces mechanical instability to glacier systems and can cause non-linear climatic response. This thesis uses glaciological and limnological data to examine the relative contributions of calving and melting to mass loss …
Our realisation of how profoundly glaciers and ice sheets respond to climate change and impact sea level and the environment has propelled their study to the forefront of Earth system science. Aspects of this multidisciplinary endeavour now constitute major areas of research. Th…

This book provides a comprehensive approach to the field of Glaciology.
"Set in the high-altitude Himalayan region of Ladakh, in northwest India, Caring for Glaciers looks at the causes and consequences of a transformation in people's relationship with the environment. It illuminates how relations of care and reciprocity-learned through everyday lif…

The Upper Ordovician Neda Formation, Midwest, USA, is composed of hematitic dolostone and ironstone that rest conformably on crinoid and bryozoan wackestone to packstone of the underlying Maquoketa Formation. Deposition occurred within the Maquoketa Sea south of the Transcontine…
Understanding the global pattern of glaciation can aid interpretation of what caused late-Pleistocene glacial cycles. Here I investigate the glacial history of the Khumbu Glacier of the Mount Everest region of Nepal. Prominent hypotheses for Himalayan glaciation suggest importan…
