  • The effect of river discharge and wind forcing on the Oregon coastal ocean during fall and winter

    Creator:
    Mazzini, Piero Luigi Fernandes
    Abstract:
    Freshwater provided from river discharge influences the dynamics and circulation of most continental shelves around the world. It has profound effects on the transport and fate of materials and substances originated from rivers and estuaries, as well as on the ocean biogeochemistry and marine ecosystems. The effect of buoyancy forcing...

  • Interactions of wind-driven and tidally-driven circulation in the Oregon coastal ocean

    Creator:
    Osborne, John J.
    Abstract:
    Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...

  • Evaluating Coastal Protection Services Associated with Restoration Management of an Endangered Shorebird in Oregon, U.S.A.

    Creator:
    Carroll, Lindsay J.
    Abstract:
    Coastal sand dunes and beaches offer a variety of ecosystem services such as coastal protection, sand stabilization, species conservation, and recreation. However, the management and balance of ecosystem services offered by dunes and beaches is challenging when ecosystem services interact across the landscape. Management focusing only on one ecosystem service...

  • Influence of upwelling-season coastal currents on near-bottom dissolved oxygen concentrations over a submarine bank

    Creator:
    Adams, Katherine A.
    Abstract:
    Wind-driven coastal upwelling brings subsurface water onto the central-Oregon shelf after the spring transition each year. This cold and salty source water is oxygen-poor, yet above the hypoxic threshold, dissolved oxygen < 1.4 ml l⁻¹. Once on the shelf, dissolved oxygen (DO) concentrations of upwelled near-bottom waters are modified by...

  • Cooperative product development between researchers and commercial fishermen to find applications for ocean condition forecasting technology

    Creator:
    Duncan, Colin
    Abstract:
    This is a case study of the cooperative development of an ocean condition forecasting tool by Oregon commercial fishermen, Oregon State University (OSU) scientists, and OSU student software engineers. Ocean condition forecasting models developed by OSU scientists were used to create an online tool to assist decision-making for fishermen. This...

  • A cooperative effort to track Humboldt squid invasions in Oregon

    Creator:
    Chesney, Tanya A.
    Abstract:
    Interannual variability of Humboldt squid (Dosidicus gigas) occurrence in the northern California Current System is largely unknown. In Oregon, the distribution of this versatile predator and what is influencing their range expansion from Mexico is poorly understood due to the recent nature of their "invasion" and a lack of monitoring....

  • Regional scale sandbar variability : observations from the U.S. Pacific Northwest

    Creator:
    Di Leonardo, Diana R.
    Abstract:
    Understanding sandbar dynamics and variability is integral to developing a predictive capacity for nearshore flows, sediment transport, morphological change, and ultimately for determining coastline exposure to damaging storm waves. Along the high-energy U.S. Pacific Northwest (PNW) coast, sandbars typically dominate the bathymetry of the active zone. Here we report on...

  • Above and Below : Oregon Coastal Phytoplankton Bloom Dynamics from Sea and Space

    Creator:
    McKibben, S. Morgaine
    Abstract:
    Phytoplankton are a sentinel class of organisms in the marine environment. Through their photosynthetic activity in sunlit waters worldwide, phytoplankton shape the health and productivity of marine ecosystems and impact the global climate. In this work a range of ocean sensing technologies (via ships, surf zone sampling, moorings, gliders, and...

  • Tidal-band and high-frequency internal variability on the central Oregon inner shelf

    Creator:
    Suanda, Sutara H.
    Abstract:
    Analogous to ocean surface waves, waves in the ocean interior also experience steepening, breaking, and dissipation as they approach the coastline. Much less is known about this internal beach. In this work, extensive moored Acoustic Doppler Current Profiler and temperature/salinity data together with optical remote sensing are combined to describe...

  • 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...
