10Be exposure ages of erratic boulders in southern Norway and implications for the history of the Fennoscandian Ice Sheet

Creator:: Goehring, Brent M.
Abstract:: This thesis focuses on the application of the cosmogenic nuclide Beryllium-10 (10Be) in an effort to better constrain the thickness history of the Fennoscandian Ice Sheet (FIS) at the Last Glacial Maximum (LGM) and into the Holocene, as well as begin to answer the long-standing question regarding the age and...

Modeling and dating glacier fluctuations and their relation to Pacific Ocean climate

Creator:: Anslow, Faron S.
Abstract:: This thesis presents the results of an investigation into the interactions between the present-day South Cascade Glacier and the former Mauna Kea ice cap at short (annual to centennial) and long (millennial and multimillennial) time scales. To quantify the response of South Cascade Glacier to atmospheric conditions, a surface energy...

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...

Development of continental magmatic systems : insights from amphibole chemistry of the Altiplano Puna Volcanic Complex, Central Andes

Creator:: Abot, Manggon
Abstract:: The pressure history of a continental magmatic system can be deciphered by analyzing the composition of amphiboles in the eruptive products where the pressure of equilibration correlates with the depth of the magmatic system. This can reveal vertical evolution of the magma as amphibole composition varies significantly with temperature and...

Past climate variability in southwestern Oregon and relationships with regional and hemispheric climate

Creator:: Ersek, Vasile
Abstract:: This dissertation presents the results of three studies that assessed climate variability on short and long timescales in western United States. The growth of carbonate formations in caves (speleothems) is used to infer the timing and amplitude of past climate variability. We first assess the controls on speleothem growth for...

The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

Creator:: Roberts, Jed T.
Abstract:: The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

Interpreting geology in Yosemite National Park, California : a monument to strong granite, powerful glaciers, and the perseverance of life

Creator:: Dunham, Sarah E.
Abstract:: This thesis develops a thematic, geology-based interpretive training manual for the interpretive staff at Yosemite National Park (YNP), California. The manual will help staff understand and convey geologic principles to park visitors who are all experiencing a dynamic landscape comprised of glacially-sculpted igneous rocks. Basic geology and the results of...

Dynamics of the Laurentide Ice Sheet

Creator:: Carlson, Anders Eskil
Abstract:: This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...

A preliminary assessment of hydrogeologic suitability for Aquifer Storage and Recovery (ASR) in Oregon

Creator:: Woody, Jen
Abstract:: An ASR metric and site rating index applied to over 120 municipal and agricultural locations across Oregon, combined with comparison to case study data from existing ASR sites, indicate that more than 50% of selected sites are hydrogeologically suitable for ASR. The ASR metric is a ratio of aquifer storage...

A study of hyporheic characteristics along a longitudinal profile of Lookout Creek, Oregon

Creator:: Ninnemann, Jeffery J.
Abstract:: The primary goal of this research project is to quantitatively measure the temporal scales of hyporheic exchange along a stream network. Our goal is to examine how hyporheic exchange varies with increasing stream size. Many previous studies focus on single stream reaches or on several reaches of similar sized streams,...
