Indicators for Monitoring Biological Integrity of Inland, Freshwater Wetlands : A Survey of North American Technical Literature (1990-2000)

Creator:: Adamus, Paul R.
Abstract:: Potentially relevant literature for the years 1990-1999 was identified by (a) conducting keyword searches of computerized bibliographic databases, especially CAB Abstracts and Aquatic Sciences and Fisheries Abstracts, (b) reading through the tables of contents of a few especially relevant journals, (c) searching the internet for pertinent bibliographies, and (d) to...

Application of Cosmogenic Nuclides and Argon Geochronology to Paleoclimate, Paleomagnetism, and Paleohydrology

Creator:: Balbas, Andrea M.
Abstract:: This dissertation uses argon geochronology and cosmogenic nuclide surface exposure dating methods to address three research questions. The first question concerns a geomagnetic instability recorded in lava flows on the island of Floreana in the Galapagos Archipelago. Changes in the Earth’s magnetic field (intensity and orientation) occur frequently throughout geologic...

Oregon's Fishing Community Adapting to Change in Policy, Management, and Markets : Documenting Women's Roles and Adaptive Capacity in an Evolving Industry

Creator:: Calhoun, Sarah M.
Abstract:: Commercial fishing research often focuses on ecological (gear, stock assessment, traceability) or economic factors. Truly understanding the social-ecological system requires considering the entire "human dimension" and this includes the social, cultural, and legal/policy aspects as well. An understudied yet important factor is women's contribution to fishing at the family and...

Decoding DOM Degradation with Metatranscriptomics : How Do Sunlight and Microbial Communities Interact to Degrade Dissolved Organic Matter in Arctic Freshwaters?

Creator:: Nalven, Sarah G.
Abstract:: Arctic soils are warming, making vast stores of organic carbon available for conversion to CO₂. This could create a positive feedback loop and accelerate global warming, but the processes that convert this carbon into CO₂ are not well understood. We investigated how the combined activities of sunlight and microbes degrade...

Distribution of Western Pond Turtle Populations in the Willamette River Basin, Oregon : Project Report to the Western Pond Turtle Working Group

Creator:: Adamus, Paul R.
Abstract:: This is the second of two new reports sponsored by a consortium of public groups and focusing on the Western Pond Turtle (Emys marmorata marmorata). The first report (Adamus 2003) provided an updated perspective on the distribution of the species in the Willamette River Basin, based on new field surveys,...

Exploring the Relationship Between 𝛿13Ccarb Signal Preservation and Algorithmic Chemostratigraphic Alignment Accuracy

Creator:: Reynolds, Paige J.
Abstract:: Changes in the stable carbon isotope composition of carbonate rocks (𝛿13Ccarb) are used to establish the relative temporal framework for geological events, such as evolutionary extinction or radiation, between two or more locations. As every local stratigraphic record is intermittent, aligning 𝛿13Ccarb records from two or more locations, a process...

Management Applications of Remotely Sensed Dynamic Seascapes: Two Case Studies

Creator:: Klajbor, Willem C.
Abstract:: Dynamic seascapes, which are classified using a combination of remotely sensed data and model output, represent a potential tool for dynamic ecosystem-based management in marine systems. This work explores the utility of seascape classification in the context of marine resource management by examining two case studies: one involving biological relationships...

Evidence for Strengthening Hadley Cells and a Westward Expansion of the Walker Circulation from Assimilation of Paleoclimate Proxy Data

Creator:: Horlick, Kaleb A.
Abstract:: A synthesis of over 2000 paleoclimate proxy records is performed via a data assimilation framework that expands upon previous efforts by implementing a suite of physically-based proxy system models, and which provides the first example of an observationally independent, multi-seasonal (DJFM, JJAS) paleoclimate reanalysis. This methodology is contrasted against previous...

Unrealized Economic Benefits in the West Coast Non-Whiting Groundfish Trawl Fishery

Creator:: Gann, Aaron K.
Abstract:: In Oregon, commercial fishing is estimated to contribute $544 million in income and 10,000 jobs per year to coastal communities. However not all fisheries are reaching their allocated quotas for catch. In 2017, 187.6 million pounds of non-whiting groundfish trawl quota worth $67 million was not attained, nearly three times...

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...
