  • 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...

  • Numerical model investigations of wind-driven coastal circulation

    Creator:
    Cervantes, Brandy T.
    Abstract:
    The effects of wind forcing on coastal ocean circulation are studied using a numerical modeling approach. The first region of interest is on the North Carolina shelf, where the Coastal Ocean Processes (CoOP) Inner Shelf Study (ISS) took place during August - November 1994. ISS observations are used to initialize,...

  • Diurnal wind-driven processes on the northern Monterey Bay inner shelf

    Creator:
    Suanda, Sutara H.
    Abstract:
    In the summer of 2007, a biophysical experiment was conducted to identify physical processes that determine the delivery of invertebrate larvae and juvenile rockfish to rocky intertidal and kelp forest communities in northern Monterey Bay, California. The experiment was sponsored by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO)...

  • Detection of Physical and Biological Fronts in the Northern California Current System and the Drivers Behind Their Seasonal to Interannual Variability

    Creator:
    Jamil, Aliya L.
    Abstract:
    Oceanic fronts mark the boundary between two water masses and are often sites of complex bio-physical processes and multi-trophic level interactions, making them particularly important features in marine ecosystems. As global climate change induces multi-scale shifts in the driving physical mechanisms of fronts, spatiotemporal tracking of frontal variability can aid...

  • Insights into Centennial-Scale Salt Marsh Morphodynamics from the Oregon Coast

    Creator:
    Peck, Erin K.
    Abstract:
    Quantification and comparison of morphological changes over the last ~300 y in Oregon salt marshes provide valuable insights into the tectonic, hydroclimatic, and anthropogenic processes shaping this important intertidal zone. Understanding of the rates and drivers of salt marsh change contextualizes intertidal habitats within the sediment routing system (i.e., source...

  • Optics, structure and variability of the offshore Columbia River plume

    Creator:
    Saldías, Gonzalo
    Abstract:
    The Columbia River delivers the greatest amount of freshwater to the coastal ocean along the U.S. Pacific coast. This freshwater forms the Columbia River plume, a mesoscale plume with significant implications on coastal ocean physical, biological, chemical, and geological processes. The plume is transported south and offshore during the upwelling...

  • Ensemble-variational data assimilation for dynamically challenging coastal ocean circulation

    Creator:
    Pasmans, Ivo
    Abstract:
    Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...
