Development of the fisheries of the Eastern North Pacific : a natural-cultural systems perspective

Creator:: Deimling, Elisabeth A.
Abstract:: The eastern margin of the Eastern North Pacific Ocean was classified into physiographic regions based on a suite of physical characteristics. Information on cultural and biological characteristics of this area was meshed with this classification. The result was a classification of the Eastern North Pacific into natural-cultural systems whose boundaries...

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...

Integrating fleets, markets and ocean dynamics : a bioeconomic analysis of the Oregon ocean shrimp fishery

Creator:: Gallagher, Charmaine Marie
Abstract:: Questions relating to economic performance, biological conservation and variation in resource abundance and harvest of ocean shrimp have led to increasing pressure for management action. Developing effective management policies for this highly variable resource requires a comprehensive understanding of the fishery and marine processes. Important factors in understanding the fishery...

Using ship tracks to characterize the effects of haze on cloud properties

Creator:: Segrin, Matthew S.
Abstract:: 1-km MODIS observations of ship tracks off the west coast of the U.S. are used to characterize changes in cloud visible optical depths, cloud droplet radii, cloud cover fraction, and column cloud liquid water amount as low-level marine clouds respond to particle pollution from underlying ships. This study re-examines the...

Are there two subgroups of albacore, Thunnus alalunga, in the North Pacific? Evidence from variability in catch, seasonal migrations, and length composition for two subgroups in the coastal fishery of North America

Creator:: Barr, Charles M.
Abstract:: North Pacific albacore (Thunnus alalunga) is a highly migratory and commercially valuable species of tuna. All stock assessments and management decisions for North Pacific albacore are presently based on the assumption of a single, uniform stock. However, a growing body of evidence from diverse sources suggests that there are two...

Effects of solar heating on the indirect effect of aerosols as deduced from observations of ship tracks

Creator:: Christensen, Matthew W.
Abstract:: One kilometer Moderate Resolution Imaging Spectroradiometer (MODIS) observations for Terra (morning) and Aqua (afternoon) satellites were used to follow the morning to afternoon evolution of marine stratocumulus clouds that were affected by ship stack exhaust. The observations covered the summer months of 2002-2003 and August 2007 for marine layers off...

Albacore tuna catches in the Northeast Pacific during summer 1969 as related to selected ocean conditions

Creator:: Panshin, Daniel Alexis
Abstract:: Oregon's commercial fishery for albacore tuna (Thunnus alalunga) is large, valuable, and variable. Little is known, however, about the oceanographic factors which determine abundance and distribution of albacore. Primarily using logbook data contributed by fishermen, this study compares albacore catches with selected ocean conditions. The study is limited to troll-caught...

Biogeography of nonindigenous species: from description to prediction

Creator:: Reusser, Deborah A.
Abstract:: Nonindigenous species are a major threat to the ecological integrity and biodiversity of marine and estuarine ecosystems. To become a successful invader, species must pass through four phases: (1) survive transport, (2) survive release, (3) establish a population, and (4) expand their range. To better understand these processes, an integrated...

Genetic patterns of demography and diversity in eastern North Pacific rockfishes (genus Sebastes)

Creator:: Johansson, Mattias L.
Abstract:: The 100 North Pacific rockfish species in the genus Sebastes are highly diverse. Rockfishes fertilize their eggs internally and release swimming larvae. Complex courting behaviors may allow female rockfish to be selective about their mates and may promote and maintain speciation. In this study, I applied genetic techniques to survey...
