  • An evaluation of criteria proposed to reauthorize the cleanup of superfund sites : case studies from EPA's Region X

    Creator:
    Williamson, Gina Denise
    Abstract:
    The United States Congress is currently debating a bill to reauthorize the 1980 Superfund Hazardous Waste Cleanup Law. If this bill is not reauthorized by the end of 1995, the program will either continue in its present form or be eliminated altogether.' As currently administered, the Superfund program sets out...

  • Geoarchaeology at Tseriadun (35CU7), Curry County, Oregon

    Creator:
    Anderson, Frederick C.
    Abstract:
    The continuation of geoarchaeological investigations at Tseriadun (35CU7) contributes to the understanding of the site's depositional history and the associated environments, thereby identifying the long term geomorphic change in the area and providing the environmental context for local human activity as it is reflected in the archaeological record. Meeting this...

  • Aging in place : a contemporary social phenomenon

    Creator:
    Lee, Megan
    Abstract:
    Most aging individuals prefer to remain in a self-determined home environment, and generally aging adults want to remain in the same home or same community. The benefits of remaining in a self-determined private home environment while aging have been established. Because individuals present a diversity of needs, it takes interdisciplinary...

  • Identification of optimal broodstock for Pacific Northwest oysters

    Creator:
    Stick, David A.
    Abstract:
    The United States Pacific Northwest is well known for its shellfish farming. Historically, commercial harvests were dominated by the native Olympia oyster, Ostrea lurida, but over-exploitation, habitat degradation, and competition and predation by non-native species has drastically depleted their densities and extirpated many local populations. As a result, shellfish aquaculture...

  • Preliminary framework for the run-ahead predictive simulation software (RAPSS)

    Creator:
    Makinson, Kevin A.
    Abstract:
    The Run-Ahead Predictive Simulation Software (RAPSS) is an architecture designed for faster-than-real-time decision support for operators of complex networks. To enable further development of the RAPSS methodology, the necessary proof of principle is illustrated in two applications: decision support for shift technical advisors in nuclear power plant control rooms (RAPSS-STA),...

  • Assessment of the accuracy of forested classifications within two broad-scale remotely-sensed vegetation databases in eastern Oregon

    Creator:
    Langhoff, Cory A.
    Abstract:
    An accuracy assessment of two broad-scale vegetation databases for eastern Oregon, both developed from satellite imagery, was performed to assess the usefulness of the databases for forest landscape planning and assessment efforts. The two databases were the Oregon Department of Forestry (ODF) vegetation database and the U.S. Geological Survey National...

  • Living with earthquakes in the Pacific Northwest

    Creator:
    Yeats, Robert S.
    Abstract:
    In this expanded new edition of Living with Earthquakes, Robert Yeats, a leading authority on earthquakes in California and the Pacific Northwest, describes the threat posed by the Cascadia Subduction Zone, a great earthquake fault which runs for hundreds of miles offshore from British Columbia to northern California. New research...

  • Improving Projections of Tidal Marsh Persistence under Climate Change with Remote Sensing and Site-Specific Data

    Creator:
    Buffington, Kevin J.
    Abstract:
    Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...

  • Evaluating the Efficacy of Predicting Bycatch Mortality Using Reflex Impairment through an Assessment of Crab Discards

    Creator:
    Yochum, Noëlle
    Abstract:
    All animals that interact with fishing gear are not necessarily captured, and all animals that are captured are not necessarily retained. Fishing practices and gear configuration, management regulations, and markets dictate which animals ultimately are retained or discarded. The impact of a fishery and the efficacy of management regulations can...

    Creator:
    Galapita Pallayapelage, Sudeera Wickramarathna
    Abstract:
    Natural resources are essential to humanity. With the increase in global development in recent decades, people must monitor the state of the environment, whose disturbance has a more significant impact on society than before. However, conventional environmental monitoring is challenged in highly dynamic ecosystems and large areas. As a solution,...
