Resurgent Uplift of Samosir Island in Toba Caldera, Indonesia : Insights from Lake Sediment Paleomagnetism and C-14 Age Determination

Creator:: Solada, Katharine
Abstract:: Around 74 ka, a supervolcano, Toba Caldera in Sumatra, Indonesia erupted, producing the Youngest Toba Tuff and its associated caldera. After this catastrophic eruption, a lake filled the caldera, sedimentation within the lake occurred, and the process known as resurgence began. Today, the resurgent dome, Samosir Island, is uplifted 700...

A Paleomagnetic and Environmental Magnetic Record from the Eastern South Pacific Sector of the Southern Ocean (0-1.7 Ma): IODP Site U1543

Creator:: Monito, Lindsey
Abstract:: This research presents a u-channel based study of the natural remanent magnetization (NRM), the laboratory magnetization, Anhysteretic Remanent Magnetization (ARM), and magnetic susceptibility (k), from the upper 100 m of International Ocean Discovery Program (IODP) Expedition 383 Site U1543 in the eastern South Pacific sector of the Southern Ocean. Alternating...

The use of surface energy balance models as a means to quantify changes in glacier mass balance : an application to the Collier Glacier

Creator:: Beedlow, Andrew Cody
Abstract:: This thesis presents the results of an investigation into the measured and modeled mass balance of the Collier Glacier, a small (0.70 km²), valley glacier located in the Oregon Cascade Range (44° 10' N, 121° 47' W). Here we present mass-balance measurements conducted for the 2009 and 2010 balance years...

Late Pleistocene and Holocene glacier and climate change

Creator:: Marcott, Shaun Andrew
Abstract:: This dissertation presents results from three studies that address major scientific questions in glacial geology and paleoclimatology for the late Pleistocene and Holocene using relatively new geochemical and statistical techniques. Each of the studies attempts to answer a longstanding question in the respective field using geochemical or statistical methods that...

Commissioning of ADAC Pinnacle for IMRT utilizing solid compensators

Creator:: Brumley, Willis E.
Abstract:: Use of solid compensators is a very effective means of implementing IMRT on any linear accelerator. The standard practice has been IMRT delivery using accelerators equipped with multi-leaf collimators (MLC’s). Truth is the addition of MLC’s to an accelerator is quite expensive. Previous studies have shown solid compensators to have...

Evaluating a Zonal-mean Hydrologic Model Against a Water Tag-enabled Global Simulation

Creator:: Mandovi, Andrew
Abstract:: The hydrologic cycle on Earth comprises the transitions among the solid, liquid, and gaseous phases of water. Understanding the hydrologic cycle is of course important for climate science, but also for agricultural, drinking water, and disaster preparedness purposes. Improvements in satellite observations and general circulation models (GCMs) have led to...

The Influence of Glacial Isostatic Adjustment on Marine Stratigraphic Correlation

Creator:: King, Meghan E.
Abstract:: Glacial isostatic adjustment (GIA) alters the amplitude and timing of ‘glacioeustatic’ sea level maxima and minima around the globe. No study has examined the intrinsic distance that one can correlate marine stratigraphic records of glacial–interglacial sedimentation across continental shelves subject to varying amounts of GIA. Here, we seek to model...

The Ocean Circulation and Carbon Cycle during the Last Glacial Maximum

Creator:: Muglia, Juan
Abstract:: During the Last Glacial Maximum (LGM, ∼ 21 ky before present) the atmospheric CO2 concentration was about 100 ppm lower than its pre-industrial (PI)value. The missing carbon from the atmosphere must have been stored in thedeep ocean during this period, but the mechanisms driving such re-distribution ofthe carbon cycle are...

Geochemical and Geostatisical Analyses of Quaternary Climate Variability over Millennial-to-Orbital Timescales

Creator:: Barth, Aaron M.
Abstract:: The goal of dissertation research was to use geochemical, statistical and geological methods to constrain and understand climate variability over several different time scales. Specifically, I have addressed three questions regarding past climate change: (1) how does the record of Irish cirque glaciers constrain the dimensions of the Irish Ice...

Application of Cosmogenic Nuclides and Argon Geochronology to Paleoclimate, Paleomagnetism, and Paleohydrology

Creator:: Balbas, Andrea M.
Abstract:: This dissertation uses argon geochronology and cosmogenic nuclide surface exposure dating methods to address three research questions. The first question concerns a geomagnetic instability recorded in lava flows on the island of Floreana in the Galapagos Archipelago. Changes in the Earth’s magnetic field (intensity and orientation) occur frequently throughout geologic...
