Applied Fisheries Oceanography: Ecosystem Indicators of Ocean Conditions Inform Fisheries Management in the California Current

Creator:: Peterson, William T., Fisher, Jennifer L., Peterson, Jay O., Morgan, Cheryl A., Burke, Brian J., and Fresh, Kurt L.
Abstract:: Fisheries oceanography is the study of ecological relationships between fishes and the dynamics of their marine environments and aims to characterize the physical, chemical, and biological factors that affect the recruitment and abundance of harvested species. A recent push within the fisheries management community is toward ecosystem-based management. Here, we...

The impact of El Niño events on the pelagic food chain in the northern California Current

Creator:: Fisher, Jennifer L., Peterson, William T., and Rykaczewski, Ryan R.
Abstract:: The zooplankton of the northern California Current are typically characterized by an abundance of lipid-rich copepods that support rapid growth and survival of ecologically, commercially, and recreationally valued fish, birds, and mammals. Disruption of this food chain and reduced ecosystem productivity are often associated with climatic variability such as El...

Climate shifts the interaction web of a marine plankton community

Creator:: Francis, Tessa B., Scheuerell, Mark D., Brodeur, Richard D., Levin, Phillip S., Ruzicka, James J., Tolimieri, Nick, and Peterson, William T.
Abstract:: Climatic effects in the ocean at the community level are poorly described, yet accurate predictions about ecosystem responses to changing environmental conditions rely on understanding biotic responses in a food-web context to support knowledge about direct biotic responses to the physical environment. Here we conduct time-series analyses with multivariate autoregressive...

The state of California, 2003 - 2004 : still cool?

Creator:: Goericke, Ralf, Venrick, Elizabeth, Mantyla, Arnold W., Hooff, Rian, Collins, Curtis A., Gaxiola-Castro, Gilberto, Bograd, Steven J., Schwing, Franklin B., Peterson, William T., Marinovic, Baldo, Durazo, Reginaldo, Huyer, Adriana, 1945-, Smith, Robert L. (Robert Lloyd), 1935-, Wheeler, Patricia A., Chavez, Francisco, Lo, Nancy, Hyrenbach, K. David, and Sydeman, William J.
Abstract:: This report summarizes the recent state of the California Current System (CCS), primarily during the period of April 2004 to January 2005. The report is based on observations made between Oregon and Baja California by various ocean observing programs. The CCS was not forced by any coherent basin-wide processes during...

Biological indicators of the timing and direction of warm-water advection during the 1997/1998 El Niño off the central Oregon coast, USA

Creator:: Keister, Julie E., Johnson, Travis B., Morgan, Cheryl A., and Peterson, William T.
Abstract:: Unusual collections of several euphausiid, chaetognath, and copepod species help elucidate the effects of the strong 1997/1998 El Niño off the central Oregon, USA, coast. Furcilia of Nyctiphanes simplex, a euphausiid typically found only as far north as central California, were collected in bi-weekly nearshore samples between December 1997 and...

Seasonal Cycle of Phytoplankton Community Composition in the Coastal Upwelling System Off Central Oregon in 2009

Creator:: Du, Xiuning and Peterson, William T.
Abstract:: Coastal upwelling in the northern California Current varies seasonally, with downwelling in winter and upwelling in summer, resulting in pronounced variability in hydrography, nutrients, phytoplankton biomass, and species composition. Winter was characterized by moderate concentrations of nitrate and silicate (averages of 10 and 18 μM, respectively) and low concentrations of...

Linking predators to seasonality of upwelling: Using food web indicators and path analysis to infer trophic connections

Creator:: Thompson, Sarah Ann, Sydeman, William J., Santora, Jarrod A., Black, Bryan A., Suryan, Robert M., Calambokidis, John, Peterson, William T., and Bograd, Steven J.
Abstract:: Upwelling in eastern boundary current systems is a primary driver of ecosystem productivity. Typically, peak upwelling occurs during spring and summer, but winter upwelling may also be important to ecosystem functions. In this study, we investigated the hypothesis that winter and spring/summer upwelling, operating through indirect trophic interactions, are important...

Multivariate Models of Adult Pacific Salmon Returns

Creator:: Burke, Brian J., Peterson, William T., Beckman, Brian R., Morgan, Cheryl, Daly, Elizabeth A., and Litz, Marisa
Abstract:: Most modeling and statistical approaches encourage simplicity, yet ecological processes are often complex, as they are influenced by numerous dynamic environmental and biological factors. Pacific salmon abundance has been highly variable over the last few decades and most forecasting models have proven inadequate, primarily because of a lack of understanding...

Biological and physical ocean indicators predict the success of an invasive crab, Carcinus maenas, in the northern California Current

Creator:: Yamada, Sylvia Behrens, Peterson, William T., and Kosro, P. Michael
Abstract:: An introduced population of European green crabs Carcinus maenas was established in San Francisco Bay (California, USA) prior to 1989. Subsequently, their larvae were likely carried northward into the embayments of Oregon, Washington (USA), and British Columbia (Canada) by the unusually strong Davidson Current during the winter of the El...

Influence of ocean ecosystem variation on trophic interactions and survival of juvenile coho and Chinook salmon

Creator:: Losee, James P., Miller, Jessica A., Peterson, William T., Teel, David J., and Jacobson, Kym C.
Abstract:: The community of trophically transmitted marine parasites of juvenile coho (Oncorhynchus kisutch) and Chinook (Oncorhynchus tshawytscha) salmon across 8 years (2002–2009) was related to indices of physical and biological ocean conditions and adult returns. When the biomass of lipid-poor, southern origin copepods in the coastal ocean was high during juvenile...
