Genetic Structure, Diversity, and Mating System of Leptasterias: Potential for Local Adaptation?

Creator:: Boring, Emily L.
Abstract:: Understanding of gene flow, connectivity, and diversity is critical to predict the stability of key marine species. The Oregon coast of the U.S.A. shows fine-scale levels of geographic variation in environmental stressors such as temperature, pH, and oxygen levels, prompting questions about the potential for local adaptation. In this thesis,...

Mapping semi-regular autonomous underwater vehicle glider observations onto a cross-shelf section

Creator:: Peery, Andrew Tristan
Abstract:: Two Autonomous Underwater Vehicle Gliders have alternated continuous sampling of a 45-nautical mile transect line (the Newport Hydrographic Line) across the Oregon continental shelf since April, 2006. Strong currents (>25cm/s) push the gliders off their trajectories as they survey this transect line, preventing them from sampling the historically occupied stations...

Sea surface height and geostrophic velocity variability in the California current system as observed from the TOPEX altimeter

Creator:: Righi, Dylan D.
Abstract:: Eight years (1994-2000) of data from the TOPEX/Poseidon satellite altimeter are used to investigate the variability of the sea surface height and geostrophic velocity of the California Current system. The TOPEX/Posiedon satellite measures SSH along an exact-repeat set of groundtracks with a 10-day repeat cycle. In the domain studied here...

Database development and application to characterize juvenile Douglas-fir (Pseudotsuga menziesii [Mirb] and understory vegetation in the Oregon and Washington Coast Range Mountains

Creator:: Shula, Robert G.
Abstract:: The Regional Vegetation Management Model (RVMM) predicts the effects of associated vegetation on the growth and yield of young Douglas-fir (age [less than or equal to] 20 years) in the Pacific Northwest, and is a 'front-end' growth model for existing rotation-age growth models. Objectives of this thesis are to: (a)...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

Scratch Explorer : a tool for assisting end-user program comprehension of animation scripts

Creator:: Zhang, Yan
Abstract:: Visual programming languages (VPLs) have been widely used to support end-user programming. However, end users are still not able to reuse code as actively as professional programmers, even when given abundant resources such as a large VPL program repository. One reason may be that current VPL development environments lack features...

Absolute water velocity profiles from glider-mounted acoustic doppler current profilers

Creator:: Ordonez, Christopher Edward
Abstract:: This paper details a method to compute absolute water velocity profiles from glider-based acoustic Doppler current profiler (ADCP) measurements based on the "shear method" developed for lowered ADCPs. The instrument is a 614-kHz Teledyne RDI ADCP integrated into the body of a Teledyne Webb Research Slocum Glider. Shear is calculated...

Assessing the Link Between Large Wood Restoration and Groundwater Recharge and Storage: An Investigation of Indian Creek in Washington State

Creator:: Boylan, Nora C.
Abstract:: With decreasing snowpacks and changing precipitation patterns, Washington State seeks ways to conserve, protect, and enhance its water supply. Stream restoration has been viewed as a means to utilize alluvial aquifers for groundwater storage and augment late-season streamflow. However, the relationship between stream restoration and groundwater dynamics is still under...
