3D vs. conventional volcanic hazard maps : a user study at Mount Hood

Creator:: Preppernau, Charles A.
Abstract:: Volcanic hazard maps inform the public on the nature and extent of the hazards that threaten them, but these maps are often challenging for those who are not trained in map use or geology. The maps in this study focus on lahars, a dangerous, fast, and far-reaching volcanic hazard that...

A characterization of early-summer terrestrial fauna and flora associated with acid mine drainage areas in the vicinity of Iron Mountain, Redding, California.

Creator:: Adamus, Paul R.
Abstract:: Surveys of flora and fauna were conducted in riparian areas of six streams in the general vicinity of the Iron Mountain mine near Redding, California. The surveys were intended to provide part of the information needed for a natural resource damage assessment (NRDA), should such an assessment be desired at...

A springtime source of toxic Pseudo-nitzschia cells on razor clam beaches in the Pacific Northwest

Creator:: Hickey, Barbara M., Trainer, Vera L., Kosro, P. Michael, Adams, Nicolaus G., Connolly, Thomas P., Kachel, Nancy B., and Geier, Susan L.
Abstract:: Concentrations of domoic acid (DA) above the regulatory limit in Washington coast razor clams are usually higher on northern beaches from summer to fall. Recent field studies have confirmed that the primary source of toxic Pseudo-nitzschia (PN) cells in those seasons is a semi-retentive topographically trapped seasonal eddy located offshore...

An Interdisciplinary approach towards understanding late Pleistocene ice sheet change

Creator:: Cuzzone, Joshua K.
Abstract:: The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...

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...

Applying economic benefit transfer to improve the transfer of ecological estimates in ecosystem services research & policy

Creator:: Errend, Melissa N.
Abstract:: The goal of this thesis is to advance the methodology and thought regarding the transferability of ecological estimates of ecosystem services. Conceptually and in practice, ecological estimate transfer parallels economic benefit transfer in ecosystem services research and policy, yet the literature for benefit transfer predates ecological estimate transfer by several...

Autonomous in situ measurements of estuarine surface PCO₂ : instrument development and initial estuarine observations

Creator:: Wall, Colleen McKay
Abstract:: A novel, low-cost instrument capable of measuring surface water PCO₂ was designed for use in dynamic, shallow-water environments. The instrument was tested in the Yaquina River Estuary, a macrotidal estuary known to experience a wide range of conditions ranging from dominance by the coastal ocean during summer upwelling to substantial...

Change in Oregon’s Nearshore Groundfish Trawl Fishery: Perspectives from Science and Industry Data

Creator:: Howard, Rebecca A.
Abstract:: The commercial groundfish fishing industry and groundfish research have a long concurrent history of activity on the Oregon continental margin. Within the non-whiting groundfish fishery, the target species are primarily flatfishes, sablefish, lingcod, and rockfishes, though landings of each have fluctuated over time. Recent work shows that over the past...

Citizen Science Research : A Focus on Historical Whaling Data and a Current Marine Mammal Citizen Science Project, Whale mAPP

Creator:: Hann, Courtney
Abstract:: Citizen science work has built the foundation of much of our knowledge on regional-scale large cetacean spatial patterns through historical whaling data. Historical whaling data on sperm whales was used as an example to show the type of ecological questions large-scale, long-term citizen science datasets can address. Results from the...

Climate and streamflow trends in the Columbia River basin: evidence for ecological and engineering resilience to climate change

Creator:: Hatcher, Kendra L. and Jones, Julia A.
Abstract:: Large river basins integrate the signal of water from atmospheres to oceans. Climate change is widely expected to alter streamflow and potentially disrupt water management systems. We tested the ecological resilience -- capacity of headwater ecosystems to sustain streamflow under climate change – and the engineering resilience – capacity of...
