Individual Transferable Quotas (ITQ) in the Pacific Halibut Fishery : Applications to the Magnuson Act

Creator:: Reisenweber, John W.
Abstract:: The Pacific halibut has supported a major commercial fishery on the West coast of the United States for over 100 years. In the past, the halibut fishery was managed by a policy of open access which led to an overcapitalized fishery and raised concerns about overfishing, fishing safety, and deteriorating...

Impact of tropical instability waves on nutrient and chlorophyll distributions in the equatorial Pacific

Creator:: Evans, William Wiley
Abstract:: Tropical instability waves (TIWs) are prominent seasonal features in both the equatorial Pacific and Atlantic Oceans. This work quantifies their role in modulating the distributions of nutrients and phytoplankton biomass. Using an eight year record of biannual ship observations along the Tropical Atmosphere Ocean (TAO) buoy array, cruise sections crossing...

Evaluation of data-poor and age-structure management strategies for west coast rockfish

Creator:: Arnold, Linsey M.
Abstract:: Management strategies to prevent overfishing while achieving optimum yield vary according to the available data and life history of the fished stock. I evaluated two sets of management strategies for Pacific coast rockfish: strategies to set harvest limits for data-poor stocks, and strategies intended to protect the age structure of...

Phosphorus control of nitrogen fixation

Creator:: Watkins-Brandt, Katie S.
Abstract:: Under conditions of fixed N-limitation, as with most oligotrophic systems, the process of biological N₂ fixation (diazotrophy) is favored, provided the necessary trace elements and vitamins are sufficient. Despite the well understood contributions of N₂ fixation in oligotrophic regions, the nutritional and ecological controls of marine diazotrophs have not been...

Diffuse deformation patterns along the North American plate boundary zone, offshore western United States

Creator:: Chaytor, Jason D.
Abstract:: Plate boundaries are commonly regions of complex, diffuse deformation with the motion across the boundary accommodated by numerous structural systems, rather than being narrow, discrete zones of deformation. One such boundary occurs where the North American plate makes contact with Juan de Fuca, Gorda, and Pacific plates along the west...

Exploring the potential for using deep-sea bamboo corals (Isidella sp.) for paleoceanographic reconstructions

Creator:: Hornung, Jonathan P.
Abstract:: Deep-sea bamboo coral (Isidella sp.) SE000901A from the southern Oregon coast (water depth 1048m) provides a high-resolution record of variability of North Pacific Intermediate Water (NPIW) and carbon rain to the sea floor, related to coastal upwelling, from 1808 to 2000AD. Counting of annual layers in magnesium to calcium (Mg/Ca)...

The leading edge of a tropical instability wave : interpretation as a gravity current

Creator:: McHugh, Elizabeth Helen
Abstract:: A sharp temperature front, oriented along the south-west corner of the leading edge of a Tropical Instability Wave (TIW) warm trough, was encountered at 0°N, 140°W on November 2, 2008 and detected by a 0.45°C increase in SST that occurred over 7 s. The distinct SST signal was observed at...

Numerical and assimilative studies of the equatorial Pacific cold tongue

Creator:: Perez, Renellys Christine
Abstract:: Numerical model and assimilation experiments were conducted in the tropical Pacific Ocean to obtain a better understanding of the processes that control the cold tongue surface mixed layer temperature balance during August 1999 to July 2004. The numerical model was first applied to test two hypotheses (asymmetric background currents and...

Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

Creator:: Kavanaugh, Maria T.
Abstract:: Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

Correlations of sea surface height and solid earth tides with seismicity in the equatorial Pacific Ocean : a GIS approach

Creator:: Zennaro, Barbara
Abstract:: In the equatorial Pacific Ocean, earthquakes are used as an indicator of tectonic stress for normal faults in the Galapagos Spreading Center, transform faults along the East Pacific Rise and thrust faults in the Middle American subduction zone. Linkages between seafloor tectonic processes and oceanographic and lunar conditions were explored...
