Structural geology of the Mount Polley Cu-Au district, south-central British Columbia

Creator:: Wafforn, Stephanie R.
Abstract:: The Mount Polley copper-gold deposit is one of a series of porphyry copper deposits that occur in a belt of accreted Mesozoic age island arc terranes in the Canadian Cordillera. The deposit comprises three breccia-hosted Cu-Au ore zones that are associated with a series of monzodiorite to monzonite intrusions emplaced...

Settling velocities of planktonic Foraminifera : density variations and shape effects

Creator:: Fok-Pun, Luis
Resource Type:: Masters Thesis

Hazards of inequality : comparing two neighborhoods in San Francisco in the 1989 Loma Prieta Earthquake

Creator:: Moore, Monika Z.
Abstract:: This study examined two neighborhoods in San Francisco with similar earthquake-induced ground failure history -- the Marina District and the South of Market Area (SoMa) -- in the aftermath of the 1989 Loma Prieta earthquake. The earthquake struck shortly after 5 pm on October 17th, 1989 and registered 6.9 in...

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...

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...

Analyzing the present and future Pacific-North American teleconnection using global and regional climate models

Creator:: Allan, Andrea M.
Abstract:: In this thesis I present the results of a comprehensive assessment of the Pacific-North American (PNA) teleconnection pattern in general circulation models (GCMs) and a regional climate model (RCM). The PNA teleconnection pattern is a quasi-stationary wave field over the North Pacific and North America that has long been recognized...

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...

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...

Do vigorous young forests reduce streamflow? Results from up to 54 years of streamflow records in eight paired-watershed experiments in the H. J. Andrews and South Umpqua Experimental Forests

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...

Late Quaternary paleoceanography of the Northeast Pacific and Atlantic Oceans based on diatom transfer functions

Creator:: Lopes, Cristina Isabel Coelho Dias
Abstract:: Modern upwelling conditions and corresponding oceanographic properties are investigated and reconstructed for the Late Quaternary. The oceanographic conditions considered influence diatom ecology and the record of fossil diatom frustules in the sediments. Diatoms from modern sediments are evaluated as paleoceanographic proxies and transfer functions (TFs) are calibrated using the Imbrie...
