Using reanalysis data to characterize Arctic and Sub-Arctic glaciers

Creator:: Ourada, Quin
Abstract:: The net mass balance fluctuations of Arctic and Sub-Arctic glaciers, north of 47.5° North latitude, are described over a 45-year period from 1957 to 2002 using two parameters derived from a gridded climatology reanalysis. Variability among 185 measured glaciers was represented according to two main components. The first component represents...

Recent periglacial debris flows from Mount Rainier, Washington

Creator:: Copeland, Elizabeth A.
Abstract:: Debris flow initiation is controlled by a complex interaction of geology, geomorphology, climate, and weather. In the Cascade Range of Pacific Northwest and mountainous areas globally, patterns of temperature and precipitation are being altered by climate change, which may in turn impact debris flow initiation. Temperature has increased and patterns...

Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...

The changing glaciers of Mt. Hood, Oregon and Mt. Rainier, Washington : implications for periglacial debris flows

Creator:: Ellinger, Jonathan R.
Abstract:: Mountain glaciers are receding worldwide with numerous consequences including changing hydrology and geomorphology. This study focuses on changes in glacier area on Mt. Hood, Oregon and Mt. Rainier, Washington where damaging debris flows have occurred in glaciated basins. Landsat imagery is used to map debris-free ice on a decadal time...

A method for remotely monitoring glaciers with regional application to the Pacific Northwest

Creator:: Medley, Brooke
Abstract:: An integrative method for monitoring glacier geometry change and mass balance is presented and applied to the Pacific Northwest, USA. Acting as a baseline for interpretation of future changes in glacier size and shape, we first derive a new inventory of regional glacier cover using remotely sensed data. To investigate...

Changing Storms and Snowpack Fate in the Western United States

Creator:: Hu, Jyun-Yi Michelle
Abstract:: Cold-season storms are responsible for generating most of the snow that accumulates in mountainous watersheds across the western United States, but with overwhelming evidence of warming temperature trends, this seasonal snowpack is at risk for melt, The vast majority of snow trend studies utilize undifferentiated air temperature records – these...

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...

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...

Canopy Effects on the Snow Hydrology of a Forested Mountain Environment in the Pacific Northwest, USA

Creator:: Roth, Travis R.
Abstract:: Rising global temperatures are having lasting effects on mountain snow environments in the form of diminishing snowpacks, shorter accumulation seasons, and shifts in meltwater timing. Seasonal snowpack is a vital source of water for natural and human systems. In the forested mountain landscapes of the Pacific Northwest seasonal snowmelt feeds...

Snow Grain Evolution in Forested and Open Regions – Implications for Remote Sensing

Creator:: Weiss, Sydney G.
Abstract:: Snow water equivalent (SWE) is a critical measurement in hydrology and water resources management. Microwave remote sensing can estimate snow water equivalent (SWE). However, the algorithms used to estimate SWE require snow grain size information. Thus, determining snow grain size is pertinent to estimate SWE. Currently, there are several models...
