Internal Composition, Structure, And Hydrological Significance Of Rock Glaciers In The Eastern Cascades, Washington, Adam Riffle
Internal Composition, Structure, And Hydrological Significance Of Rock Glaciers In The Eastern Cascades, Washington, Adam Riffle
All Master's Theses
Low summer river base flow places a strain on natural and economic resources of the Eastern Cascades. A major contributor to stream flow in this region is snow pack which has declined over the past few decades because of a warming climate. In addition, glacial runoff, which contributes significantly to base flow in summer dry periods, will diminish from glacial recession. However, rock glaciers, because their internal ice (i.e., permafrost) is insulated by an outer debris layer, react slowly to climate change, thus acting as sinks for ice and liquid water storage in mountain environments. This study utilized ground penetrating …
Advances In The Hyperspectral Imaging Microscope Spectrometer Method, And Application For Measuring The Spectral Reflectance Of Light Absorbing Aerosols From The South Cascades, Colorado Rockies, And Iceland, Melanie Swick
All Master's Theses
Snow and glaciers are receding at a global scale. Warming temperatures are often identified as the dominant cause of this decline; however, deposition of light absorbing aerosols (LAA), including black carbon, mineral dust and organics onto snow and glacier surfaces can be an even larger driver of melt in some regions (Skiles et al., 2012). Attempts to partition the relative contribution of different types of LAA to snow and glacier melt has been limited by the uncertainties in the LAA optical properties (Kaspari et al., 2014). A new hyperspectral imaging microscope spectrometer (HIMS) method was recently developed to measure LAA …
