FisherJenniferHMSCDoesLarvalAdvection.pdf

Creator:: Fisher, Jennifer L., Peterson, William T., and Morgan, Steven G.
Abstract:: Larval supply determines year-class strength of fisheries and complex ecological interactions among adults of benthic marine species. In upwelling regions, a latitudinal cline in the intensity and persistence of upwelling is thought to affect larval advection and recruitment, thereby regulating the intensity of interactions in adult populations and communities. We...

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...

Seasonal and interannual variation in the extent of hypoxia in the northern California Current from 1998–2012

Creator:: Peterson, Jay O., Morgan, Cheryl A., Peterson, William T., and Di Lorenzo, Emanuele
Abstract:: This study addresses the occurrence, severity, and extent of hypoxia over the continental shelf of the northern California Current (40–48.5°N latitude) from 1998 to 2012. Clear seasonal trends exist in the timing and duration of hypoxia. The highest bottom-water dissolved oxygen concentrations occurred from November to March, and levels below...

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...

A comparative analysis of coastal and shelf-slope copepod communities in the northern California Current system: Synchronized response to large-scale forcing?

Creator:: Bi, Hongsheng, Peterson, William T., Peterson, Jay O., and Fisher, Jennifer L.
Abstract:: The synchrony between coastal and shelf-slope copepod communities was investigated in the northern California Current (NCC) system, a strong upwelling zone, using time series of zooplankton sampled from a nearshore station (9 km offshore, water depth 62 m) and a shelf-slope station (46 km offshore, water depth 297 m). Long-term...

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...

Abstract:: In 2014, the California Current (~28˚–48˚N) saw average, or below average, coastal upwelling and relatively low productivity in most locations, except from 38˚–43˚N during June and July. Chlorophyll-a levels were low throughout spring and summer at most locations, except in a small region around 39˚N. Catches of juvenile rockfish (an...

State of the California Current 2011–2012: Ecosystems Respond To Local Forcing as La Nina Wavers and Wanes

Abstract:: The state of the California Current System (CCS) since spring 2011 has evolved in response to dissipation of La Niña through spring and summer, resurgence of cooler La Niña conditions in fall and winter, and finally a transition towards ENSO-neutral conditions in spring 2012. The resurgence of La Niña was...
