  • A Direction-Sensitive Radiation Detector for Low-Altitude, UAV-based Radiological Source Search

    Creator:
    Becker, Eric M. (Eric Matthew)
    Abstract:
    Many devices and methods for radiological searches are currently being developed, including scanning using simple detectors, mapping using large-volume detectors, and Compton imaging using 3-D position sensitive detectors. However, these devices are typically expensive and the methods used require long periods of time to generate a direction or location. The...

  • Microwave scattering from surf zone waves

    Creator:
    Catalán Mondaca, Patricio A.
    Abstract:
    Wave breaking in the surf zone is an important forcing mechanism on the generation of nearshore currents and in the driving of sediment transport. At the same time, wave breaking can have significant spatial and temporal variability that needs to be accounted for in the description of nearshore processes. Remote...

  • Bright air : geoprocessing thermal imagery to map the nocturnal dynamics of the boundary layer in a mountain valley

    Creator:
    Johnson, Christopher
    Abstract:
    A thermal infrared (TIR) camera is used to remotely sense the foliage temperature in a mountain valley. The foliage temperature is used as a proxy for air temperature and can be used to study and map the dynamics of the nocturnal, weak-wind boundary layer in this valley. All radiative flux...

  • Estimating the in situ Stratification via Remotely-sensed Internal Wave Speeds

    Creator:
    Fang, Chufan
    Abstract:
    This work investigates a methodology for estimating the ocean stratification gradient based on high-resolution, in space and time, remote sensing observations of internal wave propagation speeds. The internal wave speed observations were collected using a shore-based, X-band marine radar and the ocean vertical density profiles were collected simultaneously from an...

  • Using Satellite Imagery to Count Nesting Albatross from Space

    Creator:
    Dolliver, Jane E.
    Abstract:
    One fundamental concern in conservation biology is species abundance. For many taxa, however, these data are costly to obtain via direct observation and thus limited in geographic or temporal scope. Very high-resolution satellite imagery provides a means to address these limitations and provide remotely-sensed counts of large, colonial species. We...

  • Remote sensing of radiation stress gradients from optical imagery

    Creator:
    Killian, Jason R.
    Abstract:
    Wave-induced circulation is the defining characteristic of the nearshore. Within this region, the constant feedback cycle between incoming waves, wave-generated currents, and the mobile sediment bed is responsible for the evolution of complex patterns in nearshore and beach morphology. Central to our understanding of this system is knowledge of the...

  • Depth estimation and frontal imaging via X-band marine radar

    Creator:
    Honegger, David Andrew
    Abstract:
    This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...

  • Quantification of landslide movement in a forested environment

    Creator:
    Conner, Jeremy C.
    Abstract:
    Landslides are an insidious natural hazard, which can result in significant damage to public infrastructure. Limited monitoring tools are available, particularly tools suitable for use in forested environments. These tools often only allow a few locations across the slide to be monitored. Terrestrial Laser Scanning (TLS) shows promise as a...

  • Hybrid approach to estimating nearshore bathymetry using remote sensing

    Creator:
    Catalán Mondaca, Patricio A.
    Abstract:
    The characterization of bathymetry and its time evolution is very important for both oceanographic science applications, and for societal reasons relating to coastal engineering and development. Historically, the process of depth surveying has been costly and labor-intensive. This is especially true in nearshore regions, hence a method that is both...

  • Remote measurements of waves and currents over complex bathymetry

    Creator:
    Chickadel, Carmine C. (Carmine Christopher)
    Abstract:
    Waves are the primary input of energy in the nearshore region, and together with the currents forced through the transfer of momentum that occurs during the wave breaking process they are the principal mechanism for sediment transport in the nearshore. The basic physics of waves and currents are thought to...
