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...

Larval development of Euphausia pacifica in the laboratory: variability in developmental pathways

Creator:: Feinberg, Leah R., Shaw, C. Tracy, and Peterson, William T.
Abstract:: Gravid adult female Euphausia pacifica were collected off Newport, Oregon, USA and transferred to the laboratory, where females spawned eggs, eggs hatched, and larvae were reared at 10.5 degrees C. We fed 4 cohorts of larvae to excess with a combination of phytoplankton species and monitored them daily until they...

Relationship between oceanic mesozooplankton and energy of eddy fields

Creator:: Piontkovski, S. A., Williams, R., Peterson, William T., and Kosnirev, V. K.
Abstract:: The impact of mesoscale eddies on the spatial distribution of zooplankton biomass was analysed using data from the Arabian Sea and the Black Sea. The highest values of spatial variance of zooplankton biomass in the upper 100 to 150 m were found in regions with maximum available potential energy of...

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...

The mitochondrial genomes of Euphausia pacifica and Thysanoessa raschii sequenced using 454 next-generation sequencing, with a phylogenetic analysis of their position in the Malacostracan family tree

Creator:: Johansson, Mattias L., Sremba, Angela L., Feinberg, Leah R., Banks, Michael A., and Peterson, William T.
Abstract:: Euphausiid krill play a critical role in coastal and oceanic food webs, linking primary producers to upper trophic levels. In addition, some species support commercial fisheries worldwide. Despite their ecological importance, the genetics of these important species remain poorly described. To improve our understanding of the genetics of these ecological...

Variability in brood size and female length of Euphausia pacifica among three populations in the North Pacific

Creator:: Gomez-Gutierrez, Jaime, Feinberg, Leah R., Shaw, Tracy, and Peterson, William T.
Abstract:: We compared brood sizes among adult female Euphausia pacifica Hansen, 1911 from 3 populations in the North Pacific: Puget Sound, Washington, USA; Toyama Bay, Japan; and the Oregon coast, USA. Additionally, we used multiple linear regression models to compare the interspecific brood size as a function of female length and...

Physical versus biological spring transition: 2005

Creator:: Kosro, P. Michael, 1951-, Peterson, William T., Hickey, Barbara M., Shearman, R. Kipp, and Pierce, Stephen D.
Abstract:: In 2005, the onset of spring conditions in the physics of the coastal ocean (lowered sea level, spin-up of vertically-sheared equatorward coastal jet) came about 50 days later than average off Newport Oregon, on May 24. There was a further delay of 50 days before the subsurface upwelled water penetrated...

Abstract:: Resource managers at the state, federal, and tribal levels make decisions on a weekly to quarterly basis, and fishers operate on a similar timeframe. To determine the potential of a support tool for these efforts, a seasonal forecast system is experimented with here. JISAO’s Seasonal Coastal Ocean Prediction of the...
