A community-based approach for evaluating tradeoffs across marine ecosystem services in Oregon

Creator:: Freeman, Peter M.
Abstract:: As competing uses of our coastlines increase, natural resource agencies are employing marine spatial planning (MSP) to designate areas for different uses or activities in order to reduce conflicts while achieving ecological, economic and social objectives. A central challenge of implementing MSP is development of a rigorous approach for analyzing...

A Genetic Algorithm Approach to Imaging the Internal Southern San Andreas Fault Zone

Creator:: Reinhard, Hannah R.
Abstract:: The southern San Andreas fault (SSAF) is the fault segment with the highest 30-year probability of causing a moderate to large magnitude earthquake in California, yet key structural characteristics of the fault remain unconstrained, particularly in the Coachella Valley where the fault splits into the Banning (BF) and Mission Creek...

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...

A stratigraphic approach to characterize the deposition and storage of organic matter in reservoir sediments

Creator:: Stratton Garvin, Laurel E.
Abstract:: The relationship between carbon burial and sedimentation in reservoirs is unknown, exposing gaps in our fundamental understanding of the transport, processing, and deposition of sediment and organic matter in fluvial and lacustrine systems and contributing to uncertainty in our understanding of the net impact of dams to the global carbon...

Advancements in the Monitoring of Forests and Quantification of Live Aboveground Biomass Using Moderate Resolution Spaceborne Multispectral Imagery and Synthetic Aperture Radar Data

Creator:: Kilbride, John B.
Abstract:: The objective of this dissertation is to enhance the monitoring of forest ecosystems through the utilization of remotely sensed data to address the exigencies posed by the Anthropocene. On a global scale, rising temperatures and fluctuating precipitation patterns have strained forests and produced shifts in natural disturbance regimes. Additionally, the...

An evaluation of a water, sanitation, and hygiene (WASH) program for rural communities in northern Afghanistan

Creator:: Costello, Denise H.
Abstract:: The Water, Sanitation and Hygiene (WASH) sector of international development works to increase access to sustainable, safe water and improved sanitation. Currently, at least 780 million people live without clean drinking water and 2.5 billion without access to improved sanitation (UNICEF & World Health Organization, 2012). Lack of access to...

An Exploration of Climate Change, Conservation, and Cooperation, in Three Essays

Creator:: Johnson, Steven Mana'oakamai
Abstract:: The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

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...

Best Available Science for Wetlands of Island County, Washington : Review of Published Literature : A Report Prepared in Response to Critical Areas Ordinance Updating Requirements for Wetlands

Creator:: Adamus, Paul R.
Abstract:: This document is primarily a review of Best Available Science applicable to Island County wetlands, as needed for categorizing wetlands for regulatory actions and determining widths for buffers (setbacks) that protect the functions of wetlands. The number of technical papers and reports published on these topics is enormous, and none...
