Creator:: Alder, Jay R.
Abstract:: The El Niño/Southern Oscillation (ENSO) affects millions of people via global teleconnections in the form of drought and torrential rainfall that impact agriculture and food production in many countries. Yet how ENSO will respond to a warming world is uncertain and a greatly debated topic. The Intergovernmental Panel on Climate...
Resource Type:: Capstone Project

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...
Resource Type:: Masters Thesis

Creator:: Alder, Jay R.
Abstract:: This thesis presents the results of a formal evaluation of a new AOGCM, GENMOM, demonstrating its ability to simulate present-day climate and ENSO dynamics. The model is applied to simulate climate for the Last Glacial Maximum, deglacial, and Holocene time periods. The model output is evaluated against the best available...

Full Text:: Jones for constantly reinforcing that climate modeling is geography. To Andreas Schmittner for being

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...
Resource Type:: Dissertation

Creator:: Schmittner, Andreas, Galbraith, Eric D., Hostetler, Steven W., Pedersen, Thomas F., and Zhang, Rong
Abstract:: Paleoclimate records from glacial Indian and Pacific oceans sediments document millennial-scale fluctuations of subsurface dissolved oxygen levels and denitrification coherent with North Atlantic temperature oscillations. Yet the mechanism of this teleconnection between the remote ocean basins remains elusive. Here we present model simulations of the oxygen and nitrogen cycles that...

Creator:: Ahn, Jinho and Brook, Edward J.
Abstract:: Using new and existing ice core CO₂ data from 65 ∼ 30 ka a new chronology for CO₂ is established and synchronized with Greenland ice core records to study how high latitude climate change and the carbon cycle were linked during the last glacial period. Atmospheric CO₂ rose several thousand...

Full Text:: with us. We also thank Peter Clark, Andreas Schmittner, and Joseph Stoner at Oregon State University

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...
