  • Un Paseo encantado

    Creator:
    Joyner, Taylor B.
    Abstract:
    Un Paseo Encantado, an enchanted walk, is a collection of my observations and experiences in a study abroad program in Oviedo, Spain. My commentary on Spanish culture is based on reading I did prior my departure, in combination with my observations while in Spain. In six chapters, I explore the...

  • Water, energy, and ecosystem services : a study of businesses in Oregon's Willamette Valley

    Creator:
    Hunter, Maria Lewis
    Abstract:
    This study uses interviews with 18 businesses in Oregon's Willamette Valley to explore business investment in the environment, and how this relates to ecosystem services, payment for ecosystem services programs, and the water-energy nexus. Our research led us to outline 5 factors that influence business investment in the environment, those...

  • Electron Diffraction of Neutral and Cationic Clusters Doped into Superfluid Helium Droplets

    Creator:
    Lei, Lei
    Abstract:
    In this dissertation, I describe the experimental investigation of electron diffraction of neutral and ionic clusters doped into superfluid helium droplets. The project is aimed at contributing to the development of an overall approach called ‘serial single molecule electron diffraction imaging (ss-EDI), a potential approach to solve macromolecule structures bypassing...

  • The South Atlantic Ocean response to local and remote forcings

    Creator:
    Fetter Filho, Antonio F. H.
    Abstract:
    The local and remote sources of variability of the South Atlantic Ocean are investigated using a set of numerical experiments and satellite data. A global, eddy-permitting, numerical simulation is analyzed to investigate the dynamical links between the Antarctic Circumpolar Current (ACC) and the Malvinas Current (MC). The model results indicate...

  • Processes Contributing to Bering Sea Temperature Variability in the Late 20th and Early 21st Century

    Creator:
    Hayden, Emily E. and O'Neal, Larry W.
    Abstract:
    Over recent decades, the Bering Sea has experienced oceanic and atmospheric climate extremes, including record warm ocean temperature anomalies and marine heatwaves (MHWs), and increasingly variable air-sea heat fluxes. In this work, we assess the relative roles of surface forcing and ocean dynamical processes on mixed layer temperature (MLT) tendency...

  • Simulating past, present, and future changes in ENSO : a model evaluation and data-model comparison

    Creator:
    Alder, Jay R.
    Abstract:
    This thesis presents the results of a formal evaluation of a new AOGCM, GENMOM, demonstrating its ability to simulate present-day climate and ENSO dynamics. The model is applied to simulate climate for the Last Glacial Maximum, deglacial, and Holocene time periods. The model output is evaluated against the best available...

  • Three Topics on Coastal Hazards : Propagation, Transformation, and Impact

    Creator:
    Ko, Harrison T.
    Abstract:
    An understanding of natural coastal hazards is essential for improving resilience of coastal communities. Effective management of coastal hazards relies on prediction tools and mitigation structures that have been designed to handle the dynamic coastal system. This dissertation is a collection of manuscripts that cover a diverse range of fundamental...

  • A Study of Vegetation Change Over Time in the Salt Marshes of the Salmon River Estuary, Oregon

    Creator:
    Schrank, Keaton A.
    Abstract:
    The salt marshes of the Salmon River Estuary, Oregon have been of interest for decades due to their disturbance and restoration history, as well as the presence of long-term vegetation transects that were established as early as the 1970s. Vegetation abundance data have been gathered in the four sites of...

  • Surface wind modification near mid-latitude ocean fronts : observational and dynamical analysis

    Creator:
    O'Neill, Larry W.
    Abstract:
    Interactions between surface winds and meanders in mid-latitude sea surface temperature (SST) fronts with horizontal length scales of 100-1000 km are investigated from satellite observations and numerical simulations. Observations from the Sea- Winds scatterometer on the QuikSCAT satellite show that the magnitude, direction, curl, and divergence of the surface wind...

  • Spatial relationships for vegetation in restored and reference salt marshes in the Salmon River Estuary, Oregon

    Creator:
    Chellew, Megan
    Abstract:
    In this thesis, the spatial patterns of vegetation and soils of reference and restored tidal marshes were compared to determine the extent to which restored sites differ from the reference site after 40 years of restoration. Vegetation surveys of 1m x 1m plots were conducted along previously-established transects of salt...
