Emotional Evidence of Change: Highlanders Experiences with Glacial Retreat in Peru
Global climate change is a phenomenon studied by some, but experienced by many. Communities in various places across the globe live with the physical and social effects of that phenomenon each day, with the most highly vulnerable residing in developing countries, especially those in mountainous …

Divergence of Threespine Stickleback That Differ in Nuptial Coloration
… occurred in several locations following glacial retreat. We measured phenotypic variation in a suite of traits and used next generation sequencing to characterize within-species and among-morph genetic variation between the two morphs. We found substantial phenotypic and genetic …

Biogeochemical investigations of methane-rich groundwaters in high Arctic glacial catchments
… fast as the average for the Arctic, glaciers are retreating and leaving behind exposed forefields that enable rapid methane escape. Through an extensive spatial study of proglacial groundwater springs on Svalbard, groundwater systems within glaciated catchments are found to be bringing to the …

Confronting Glacial Hazards: A Study of Disaster Impact and Community Adaptation to Glacial Lake Outburst Floods in Hunza, Pakistan
As climate change hastens glacial retreat across the world, high mountain communities face increasing risks from glacial lake outburst floods (GLOFs) with limited capacity to mitigate their impact and recover from repeated cycles of losses. This thesis looks at the Hassanabad settlement in Hunza, …

Modeling Subglacial Hydrology in the Himalayas
… which provide water to over a billion people. Glacial retreat, glacial lake outburst flooding (GLOFs), surge behavior, and glacial ice mass balance are all likely strongly affected by subglacial hydrology. Unfortunately, little is known about Himalayan glaciers due to their remoteness and the …

Impact assessment of hydroclimatic change on water stress in the Indus Basin
… River flows, primarily fed by snow and glacial melt, are highly seasonal and fluctuate between intense floods and droughts. Built storage is relatively small, with withdrawals averaging at 70% of annual availability. Climate change, growth in sectoral water demands, and changes in water …

The Response of High Elevation Wetlands to Past Climate Change, and Implications for the Future
… the kettle lake formed shortly after the Last Glacial Maximum, at least 16,201 cal yr BP and that peat began accumulating in Whiskey Fen 12,347 cal yr BP. The timing of the formation of this kettle lake provides new details towards the timing of glacial retreat after the Last Glacial Maximum. …

Late Devensian ice sheet dynamics and the deglaciation of the Hebridean shelf, western Scotland, UK
… shelf to the shelf-break during the last glacial cycle and drained a large portion of the northern sector of the British Irish-Ice Sheet (BIIS). This area has not received much attention in past studies.<br/>This thesis aims to examine how the HIS evolved and interacted with the changing …

Late Pleistocene Stratigraphy And Events In The Asbestos-valcourt Region, Southeastern Quebec
… of the Asbestos-Valcourt region indicates that glacial sediment deposite during at least two regional glacial advances underlie Late Wisconsinan ice-contact and glaciolacustrine sediments. Glaciolacustrine sediments (unit B), which underlie surface till (drift unit C), were deposited during a …

Plant Successional Patterns at Sperry Glacier Foreland, Glacier National Park, MT, USA
… changes in the climate have been driving rapid glacial retreat in many glaciers since the Little Ice Age. This retreat provides a unique opportunity to study succession across the chronosequences of glacier forelands. Patterns of plant colonization and succession on terrain exposed by retreating …

Föhn winds on South Georgia and their impact on regional climate
… with this has been an increase in the rate of glacial retreat throughout the last century, with glaciers on the northeast leeside of the island retreating at a faster rate than those on the southwest side. These asymmetrical changes are thought to be linked with the strengthening of the …

The resilience of Polar Collembola to climate change
… colonisation patterns of new habitat exposed by glacial retreat. This review illustrated that polar Collembola exhibit a suite of traits that have enabled their survival in extreme conditions and may serve as pre-adaptations to changing conditions. However, if resistance capacities are …

Utilisation of remote sensing for the study of debris-covered glaciers: development and testing of techniques on Miage Glacier, Italian Alps
… many present glaciological studies. Since future glacial monitoring will increasingly have to consider supraglacial debris cover as a common occurrence, due to climate warming impacts of glacial retreat and permafrost melting. This contribution is achieved through the successful application of …

Tectonic and climatic control on the evolution of the Himalayan mountain front
… (ISM). During strengthened ISMs sand post-LGM glacial retreat, aggradation occurred in the Kangra Basin, likely due to high sediment flux, whereas periods of a weakened ISM coupled with lower sediment supply coincided with renewed re-incision. However, the evolution of fluvial terraces along …
