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...

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...

Properties of low-level marine clouds as deduced from advanced very high resolution radiometer satellite observations

Creator:: Chang, Fu-Lung
Abstract:: A radiation model was developed for retrieving cloud visible optical depth, droplet effective radius, and cloud top emission temperature using AVHRR satellite observations at 0.63, 3.7, and 11 μm. The model was used to determine the sensitivity of the retrieved properties to various approximations often employed in such retrievals. Droplet...

Identification of layered cloud occurrences from the Lidar In-Space Technology Experiment and advanced very high resolution radiometer imagery

Creator:: Stevermer, Amy J.
Abstract:: Realistic assessment of the vertical distribution of clouds, particularly the occurrence of multi-layered systems, is critical for accurate calculations of radiative transfer in general circulation models. Such information is also useful in the design and improvement of satellite retrieval techniques. Current methods for retrieving cloud properties from satellite data assume...

Properties of semitransparent upper-level clouds deduced from multispectral imagery data

Creator:: Lin, Xijian
Abstract:: A multispectral retrieval method is developed on the 100 km regional scale to extract the temperature, particle size, fractional cover and 11-μm emissivity of clouds which may be semitransparent in the infrared based on emitted radiances. The scheme utilizes the nonlinear relationship between emitted radiances when clouds are semitransparent and...

Biases in droplet radii and optical depths of marine stratocumulus retrieved from MODIS imagery

Creator:: Boeke, Robyn C.
Abstract:: The 2007 Intergovernmental Panel on Climate Change assessment established that the effect of clouds on climate contributes the largest uncertainty in predicting the future climate. Satellite observations provide an opportunity for learning about the behavior of clouds. This thesis seeks to assess the accuracy of cloud properties retrieved from multispectral...

Properties of marine stratus and stratocumulus derived using collocated MODIS and CALIPSO observations

Creator:: Hayes, Christopher R.
Abstract:: Adiabatic parcel models suggest specific relationships between cloud thickness and cloud properties. Such relationships govern cloud radiative forcing and thus cloud feedbacks in the climate system. Current remote sensing techniques work well at measuring these properties in low-level cloud systems that are overcast. Significant biases exist, however, when measuring cloud...

Development of 2D models to estimate nearshore bathymetry and sediment transport

Creator:: Splinter, Kristen D.
Abstract:: We examine the interactions and feedbacks between bathymetry, waves, currents, and sediment transport. The ﬁrst two pro jects focus on the use of remote sensing techniques to expand our knowledge of the nearshore. Due to the plethora of snap-shot data that is available from satellites and their distribution via Google...

A comparison of seafloor sonar classification methods through the use of error matrices and 3 dimensional GIS visualization : a multibeam sonar investigation of Nehalem Bank, Oregon

Creator:: Lanier, Andrew S.
Abstract:: Multibeam sonar data was collected on Nehalem Bank, off of the Oregon Coast with the purpose of increasing the spatial resolution of our knowledge of the area and delineating seafloor habitats. The system used was the Kongsberg Simrad EM-300 operating at 30 kHz. The data set collected includes both topographic...

Benefits of Geographic Information Systems for State and Regional Ocean Management

Creator:: Sowers, Derek C.
Abstract:: The current and potential benefits of using geographic information systems (GIS) to support state-level and regional-scale ocean management in the United States are evaluated. Specifically, the role of GIS in facilitating improved integration of management strategies for a variety of resource use issues across multiple management jurisdictions is examined, along...
