Regional Scale Modeling of Climate, Cryosphere, and Freshwater Discharge in Changing Coastal Mountain Environments

Creator:: Beamer, Jordan P.
Abstract:: The glaciated coastal mountain watersheds that drain into the Gulf of Alaska (GOA) provide a model laboratory to explore the challenges of hydrological modeling and study the impact of climate and glacier cover change on regional hydrology. The region is data-sparse and contains a complex assemblage of topography and land...

Understanding Drivers of Glacier Length Variability Over the Last Millennium

Creator:: Huston, Alan C.
Abstract:: Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation, but when do such changes indicate forced climate change, and when do they indicate natural variability? In this study, we simulate the past ~1000 years of glacier length variability across the globe using the 3-stage...

Atmospheric and Sea Ice Circulation Patterns During Lead Formation at Point Barrow

Creator:: Jewell, MacKenzie E.
Abstract:: In winter and spring, ice-coast interactions driven by winds and ocean currents cause sea ice fractures (leads) to form repeatedly along Arctic coastlines. These events are often associated with rapid and expansive changes in sea ice drift and state that are challenging to predict and represent in models. We investigate...

Measuring Bubble Pressure in Glacier Ice

Creator:: Clonch, Cameron E.
Abstract:: Recent observations of tidewater glaciers find that the currently accepted model for predicting ice melt vastly underestimates observed melt rates. The release of pressurized air bubbles into the ocean from pores in the ice is one process that can amplify glacier melt. To incorporate this process into models, we need...

Mapping Wildlife-Relevant Snow Properties in Arctic-Boreal North America; Novel Modelling, Remote-Sensing, and Ground Observation Approaches

Creator:: Cosgrove, Christopher Liam
Abstract:: Arctic-boreal regions are exhibiting the symptoms of profound ecological shifts as they experience pronounced warming. Wildlife in high-latitudes are one such harbinger of change, and their populations are undergoing range-shifts, declines, and extinctions in response to their rapidly altering habitats. As the circumpolar and boreal north is snow-covered for up...

Advancing Understanding of Changes in the Cryosphere of the Western United States and Alaska: A Case for the Importance of Spatial and Temporal Scaling

Creator:: Roberts-Pierel, Benjamin M.
Abstract:: The global cryosphere, defined as the world’s ice and snow covered regions, is a crucial water source for society and ecosystem functions, as well as an important regulator of the earth’s energy budget. Melt from glaciers and seasonal snow cover provides water for more than a sixth of the world’s...

A Case Study of Solar Warming and Subsequent Mixing in the Arctic Upper Ocean for the 2011 Spring-Summer Transition

Creator:: Lee, Ara
Abstract:: Autonomous buoys were deployed in 2011 in the central Arctic: An Ice-Tethered Profiler (ITP) and Ice Mass Balance (IMB) buoys were deployed in the Makarov basin; a Polar Ocean Profiling System (POPS) and Ice Thickness (Ice-T) buoy were deployed on the Eurasian Basin. The two different sites were approximately 70km...

Estimating basal glacier conditions using internal layer slopes

Creator:: Carroll, Georgia
Abstract:: Ice-penetrating radar produces detailed images of the internal ice layers in a glacier. Because the layers form from each year's snowfall, the curving of the internal layers is a record of the climate conditions that the glacier experienced as it flowed throughout the millennia. The Hiawatha Glacier lies on top...

New Metrics, Modeling Applications, and Observational Strategies for Snowpacks in Remote, Data-Limited, Mountain Environments

Creator:: Crumley, Ryan L.
Abstract:: The topics in this dissertation center on the snow processes that dominate mountain environments in the Western U.S. and Alaska, particularly in locations lacking long-term observational datasets or locales that are difficult to access in-person. Some are currently glacierized or have been glaciated in the recent past. Each of the...

Exploring the Relationships Between Stable Water Isotope Ratios and Large Scale Atmospheric Circulation in Paleoclimate Settings Using an Isotope-Enabled General Circulation Model

Creator:: Niezgoda, Kyle
Abstract:: Climate model simulations and paleoclimate proxies are two tools that enable an understanding of the climate history of the Earth. When utilized together, they form a powerful paradigm for understanding past changes. Proxies are the only physical link to the past conditions on Earth, and models “fill in the gaps”...
