Variability in mesoscale circulation and its effects on zooplankton distribution in the Northern California Current

Creator:: Keister, Julie Eileen
Abstract:: In eastern boundary current upwelling ecosystems, mesoscale circulation features such as eddies and upwelling filaments play a prominent role in the transfer of water and the associated plankton from the productive nearshore to the oligotrophic deep sea. The relationship between mesoscale circulation, zooplankton distributions, and the across-shelf transport of coastal...

Upper ocean water properties and currents along paired sections in the Northern California current, spring 1998-2003

Creator:: Fleischbein, Jane H., Huyer, Adriana, 1945-, Kosro, P. Michael, 1951-, Smith, Robert L. (Robert Lloyd), 1935-, Wetz, Jennifer Jarrell, and Wheeler, Patricia A.
Abstract:: As part of the U. S. GLOBEC NorthEast Pacific Program we made repeated seasonal hydrographic surveys in the northern California Current system (Figure 1) between July 1997 and September 2003. These surveys included early spring sampling along a pair of hydrographic sections, one north (at 44.6ºN) and one south (at...

Tsunami and hurricane wave loads on bridge superstructures

Creator:: Azadbakht, Mohsen
Abstract:: This dissertation examines tsunami and hurricane wave loads on bridge superstructures. Tsunamis have caused significant damage to coastal communities in recent years. For example, the 2011 Great East Japan Earthquake and resulting Tohoku Tsunami destroyed infrastructure along the east coast of Japan including bridge superstructures. Recent hurricanes have also caused...

Trophically transmitted parasites as ecosystem indicators : relationships among parasite community structure, juvenile salmon diet composition, and ocean conditions

Creator:: Losee, James P.
Abstract:: Recent research conducted throughout the Northern California Current (NCC) on the ecology of Pacific salmon (Oncorhynchus spp.) indicates that variable ocean conditions affect the community composition of zooplankton in the nearshore environment which, in turn, can affect the quality of prey for fish, sea birds and mammals. Interannual variability in...

Trophic dynamics of marine nekton and zooplankton in the Northern California Current ecosystem

Creator:: Miller, Todd William
Abstract:: The Northern California Current (NCC) ecosystem exhibits extreme seasonal, interannual and interdecadal shifts in the abiotic environment and shifts in primary and higher production. This variability is also apparent in the spatial structure of the ecosystem with nearshore-shelf waters (<150 m isobath) being highly productive and having a different community...

The role of oxygen and other environmental variables on survivorship, abundance, and community structure of invertebrate meroplankton of Oregon nearshore coastal waters

Creator:: Eerkes-Medrano, Dafne I.
Abstract:: The high productivity of Eastern Boundary Upwelling Ecosystems (EBUE), some of the most productive ecosystems in the globe, is attributed to the nutrient rich waters brought up through upwelling. Climate change scenarios for coastal upwelling systems, predict an intensification of coastal upwelling winds. Associated with intensification in upwelling are biogeochemical...

The ecology of ocean acidification : integrating the effects of pH variation among other environmental stressors on biogeography and organismal performance in rocky intertidal communities

Creator:: Rose, Jeremy M.
Abstract:: Ocean Acidification (OA) has emerged as a major threat to marine ecosystems, particularly regarding calcifying organisms. A growing body of literature describing laboratory investigations into pH stress indicates broadly deleterious effects for calcifiers, but responses vary greatly across taxa and can be influenced by variations in other environmental characteristics. Scaling...

Tags Versus Genetics : Identifying Which Tool Provides the Best Information about Chinook Salmon (Oncorhynchus tshawytscha) Distributions in the California Current

Creator:: Flaherty, Ryan James
Abstract:: The movement of Chinook salmon through space and time, across political boundaries, and through fisheries, creates one of the most complex marine resource management problems in the world. Information garnered from the recovery of coded-wire tags (CWTs) has been used since the 1970s to direct management decisions. Growing concern surrounding...

Seasonal variability of zooplankton off the California coast : box model approach

Creator:: Barnard, Andrew Heath
Abstract:: In an effort to elucidate the mechanism responsible for large-scale zooplankton variability in the California Current, zooplankton biomass and hydrographic data from the California Cooperative Fisheries Investigation data set and wind data from Fleet Numerical Oceanography Center model analyses have been used to construct a box model biomass budget. The...
