An experimental investigation of the effects of temperature and dissolved oxygen on the growth of juvenile English sole and juvenile Dungeness crab

Creator:: Bancroft, Morgan P.
Abstract:: In the past two decades, occurrences of summertime upwelling-driven low dissolved oxygen (DO) events, or hypoxia, have increased along the northeast Pacific coast. If hypoxic events are severe enough to cause marine species mortality, the areas affected are often called "dead zones." In 2002 and again in 2006, the events...

Physical factors affecting the spatial distribution of infaunal bivalve assemblages and species along the continental shelf of the Pacific Northwest

Creator:: Labou, Stephanie Grace
Abstract:: The spatial distribution and abundance patterns of benthic infauna result from interactions with a host of environmental variables including sediment characteristics (percent silt-clay, grain size, total organic carbon), depth, temperature, and dissolved oxygen. This thesis focuses on the association of bivalve assemblages and species with potentially influential environmental variables along...

A Study of Participant Perspectives Regarding Cooperative Fisheries Research on the US West Coast

Creator:: Moore, Jedidiah J.
Abstract:: Cooperative marine fisheries research—the practice of involving the expertise of fishermen and scientists in conducting studies of ocean fishes—has increased gradually over the past 50 years on the US west coast. However, few studies have systematically collected and analyzed the experiences and perceptions of numerous cooperative marine fisheries research project...

Identification of representative west coast areas for manganese nodule processing activities

Creator:: Henderson, James A.
Abstract:: Manganese nodules are concretions which are widely distributed on the bottom of marine waters as well as on the bottom of some lakes. They vary in size, abundance, and to some extent composition, with location. The nodules are of potential economic value because of the nickel, copper, cobalt and manganese...

Irrigation choices for major West Coast crops : water scarcity and climatic determinants

Creator:: Olen, Beau
Abstract:: Recent climate change forecasts have aroused growing interest in the influence of water scarcity and climate on agricultural production and irrigation practice. However, it is common in the economic literature to aggregate disparate crops when modeling irrigation choices. That approach confounds the crop-specific effects of climate and water scarcity that...

Educational needs assessment of designers in west coast states : architects and engineers on the topic of wood products

Creator:: Roth, Travis J.
Abstract:: Architects and engineers are two key types of design professionals who influence the use of wood products in construction. Eighty to ninety percent by volume of all residential structures in the U.S. are wood (Gupta, 2005). In 2010, the non-residential market was made up by 10% wood, 60% steel and...

Response of marine stratus to successive polluting events by ships

Creator:: Sechrist, B.
Abstract:: Ship tracks have proven to be an ideal laboratory for studying the response of marine stratocumulus to an increase in aerosol pollution. Here the response of already polluted marine stratocumulus to further pollution was examined by studying the clouds where two ship tracks cross. 78 crossings of ship tracks were...

Stakeholder evaluation of market based approaches towards managing the adverse impacts of commercial fishing on the marine environment

Creator:: Swart, Brycen
Abstract:: Over fishing, by-catch of non-target fish species, marine mammals, seabirds, and damage to benthic habitats remain serious problems in fisheries management. Management methods based on traditional command and control (CAC) approaches may meet with initial successes yet additional progress is often marginal, requiring managers to implement additional regulations to achieve...

Using an indicator model to rank relative stock status of minor West Coast rockfish species

Creator:: Miller, Stacey D.
Abstract:: Quantitative assessments of many West coast rockfish stocks of both major and minor importance to commercial fisheries have shown varying declines in abundances. The population sizes of less-abundant, co-occurring unassessed species may also be declining. However, determining stock status of the many non-targeted, minor species with high levels of certainty...

Abstract:: Nearshore and estuarine environments along the U.S West Coast are ocean acidification (OA) "hotspots". Carbon dioxide-enriched water has been correlated with production losses of Pacific oyster (Crassostrea gigas) larvae at hatcheries in the Pacific Northwest. Limited and unreliable supply of larval seed has implications for the economic well-being of commercial...
