  • Satellite observations of the influence of mesoscale ocean eddies on near-surface temperature, phytoplankton and surface stress

    Creator:
    Gaube, Peter
    Abstract:
    The influence of mesoscale ocean eddies on near-surface ocean temperature, surface stress and phytoplankton communities is investigated by collocating numerous satellite measurements along with vertical profiles of oceanic temperature and salinity to the interiors of eddies identified and tracked in altimetric sea surface height maps. The surface currents associated with...

  • Ocean Temperature Variability during the Late Pleistocene

    Creator:
    Hoffman, Jeremy Scott
    Abstract:
    This dissertation explores one overarching question relevant to the paleoclimate of the latest Pleistocene glacial cycle (approximately the last 130,000 years): “How did spatial and temporal evolution of ocean temperature, both at the surface and interior, relate to other parts of the climate system in the late Pleistocene?” Results from...

  • Hydrodynamic and Morphologic Controls on Extreme Coastal Total Water Levels Across Regional and Local Scales

    Creator:
    Serafin, Katherine A.
    Abstract:
    Coastal and estuarine flooding and erosion events are usually driven by the cumulative effect of multiple individual processes like waves, streamflow, storm surge, and/or tides. This dissertation focuses on separating the influence of the regional and local-scale geomorphologic and hydrodynamic processes driving variability in the magnitude and impacts of extreme...

  • From the Shoreface to the Foredunes : Coastal Morphodynamics Across the Land-Sea Interface

    Creator:
    Cohn, Nicholas T.
    Abstract:
    Coastal flooding and erosion are major concerns for low lying coastal communities -- particularly in light of accelerated sea level rise and climate change. To improve quantitative understanding of the physical drivers of both flooding and coastal landscape change, this dissertation explores coastal morphodynamics bridging the land-sea interface on modally...

  • Simulating extreme total water levels using a time-dependent, extreme value approach

    Creator:
    Serafin, Katherine A.
    Abstract:
    Coastal flood hazard zones and the design of coastal defenses are often devised using either the maximum recorded total water level (TWL) or a 'design' event such as the 100-year return-level flood, usually projected from observed extreme events. Despite technological advances driving more consistent instrumental records of wave heights and...

  • An Interdisciplinary approach towards understanding late Pleistocene ice sheet change

    Creator:
    Cuzzone, Joshua K.
    Abstract:
    The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...

  • Quantifying dune ecomorphodynamics using UAV-based structure from motion photogrammetry

    Creator:
    Edgell, Rebecca
    Abstract:
    Oregon’s foredunes are part of a dynamic coastal environment that constantly evolves in response to both ecological and physical forces. Invasive beachgrasses have outcompeted native dune grass in the region and have influenced the shape of Oregon’s foredunes via species-specific biophysical feedback mechanisms. As climate change induced sea-level rise will...

  • A Tale of Two Counties : Exploring Co-Produced Coastal Adaptation Strategies in Tillamook County, OR and Grays Harbor County, WA

    Creator:
    Evans-Wilent, Janan K.
    Abstract:
    Coastal communities throughout the US West Coast and elsewhere are facing the daunting task of preparing for climate change impacts, particularly the hazards from increased flooding and erosion. With sea-level rise, changing storminess patterns, and possible changes to the frequency and severity of major El Niño events, communities are already...

  • Assessing Coastal Community Adaptation Scenarios in the Face of Climate Change : A Tillamook County, Oregon Example

    Creator:
    Lipiec, Eva
    Abstract:
    Recent coastal disasters (e.g., Hurricane Sandy, Typhoon Haiyan) and chronic issues (e.g., Florida's "nuisance flooding") provide numerous examples of coastal communities struggling to adapt in the face of climate change impacts. Decision-makers and the public alike must reconcile the lack of "fit" between a rapidly changing environment and the effects...

  • 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...
