The late holocene atmospheric methane budget reconstructed from ice cores

Creator:: Mitchell, Logan E.
Abstract:: Ice cores are considered the gold standard for recording past climate and biogeochemical changes. However, gas records derived from ice core analysis have until now been largely limited to centennial and longer timescales because sufficient temporal resolution and analytical precision have been lacking, except during rare times when atmospheric concentrations...

Analyzing large paleoclimate datasets : implications for past and future climate change

Creator:: Shakun, Jeremy D.
Abstract:: This dissertation presents the results of statistical analyses of large climate datasets from two time intervals – the 20th century instrumental record and the proxy record of the last deglaciation – in order to understand the forcings and mechanisms of past climate variability. A longstanding question in climate dynamics concerns...

Ocean Temperature Variability during the Late Pleistocene

Creator:: Hoffman, Jeremy Scott
Abstract:: This dissertation explores one overarching question relevant to the paleoclimate of the latest Pleistocene glacial cycle (approximately the last 130,000 years): “How did spatial and temporal evolution of ocean temperature, both at the surface and interior, relate to other parts of the climate system in the late Pleistocene?” Results from...

Paleoclimate, paleoventilation, and paleomagnetism as recorded in a 17kyr marine sediment record from the SE Alaska margin

Creator:: Davies, Maureen Helen
Abstract:: The deglacial behavior of the sub-Arctic North Pacific is poorly constrained, with many published records suffering from limited age control due to extensive post- depositional biogenic carbonate dissolution. Potential alternative dating methods could include the correlation of stable-isotopic and/or paleomagnetic secular variation records to an independently-dated regional template, however no...

Carbon cycle variability during the last millennium and last deglaciation

Creator:: Bauska, Thomas K.
Abstract:: The exchange of carbon on earth is one of the fundamental processes that sustains life and regulates climate. Since the onset of the Industrial Revolution, the burning of fossil fuels and anthropogenic land conversion have altered the carbon cycle, increasing carbon dioxide in the atmosphere to levels that are unprecedented...

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...

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...

Exploring perceptions and experiences of the U.S. West Coast shellfish industry dealing with ocean acidification

Creator:: Mabardy, Rebecca Anne
Abstract:: Nearshore and estuarine environments along the U.S West Coast are ocean acidification (OA) "hotspots". Carbon dioxide-enriched water has been correlated with production losses of Pacific oyster (Crassostrea gigas) larvae at hatcheries in the Pacific Northwest. Limited and unreliable supply of larval seed has implications for the economic well-being of commercial...

Late Cenozoic Climate, Ice-sheet and Earth-surface Evolution Derived from Terrestrial and Marine Sedimentary Archives

Creator:: Bill, Nicholas S.
Abstract:: The goals of this dissertation are centered on understanding changes in Earth surface and climate systems through the use of geologic proxies as records of past changes in these systems. Specifically, this dissertation (1) establishes a new chronology for retreat of the Ross Sea sector of the West Antarctic Ice...

Changing landscape, climate, and life during the age of mammals: interpreting paleontology, evolving ecosystems, and climate change in the Cenozoic fossil parks

Creator:: Kenworthy, Jason P.
Abstract:: This thesis develops a manual for interpreters at six National Park Service areas established to preserve and interpret fossils of the Cenozoic Era: Fossil Butte National Monument (Wyoming), John Day Fossil Beds National Monument (Oregon), Badlands National Park (South Dakota), Florissant Fossil Beds National Monument (Colorado), Agate Fossil Beds National...
