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...

Synthesis of Pacific Ocean Climate and Ecosystem Dynamics

Creator:: Di Lorenzo, Emanuele, Combes, Vincent, Keister, Julie E., Strub, P. Ted, Thomas, Andrew C., Franks, Peter J. S., Ohman, Mark D., Furtado, Jason C., Bracco, Annalisa, Bograd, Steven J., Peterson, William T., Schwing, Franklin B., Chiba, Sanae, Taguchi, Bunmei, Hormazabal, Samuel, and Parada, Carolina
Abstract:: The goal of the Pacific Ocean Boundary Ecosystem and Climate Study (POBEX) was to diagnose the large-scale climate controls on regional transport dynamics and lower trophic marine ecosystem variability in Pacific Ocean boundary systems. An international team of collaborators shared observational and eddy-resolving modeling data sets collected in the Northeast...

Creator:: Batchelder, Harold P., Daly, Kendra L., Davis, Cabell S., Ji, Rubao, Ohman, Mark D., Peterson, William T., and Runge, Jeffrey A.
Abstract:: The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental controls on zooplankton vital rates, especially the timing and magnitude of reproduction, growth, life-cycle progression, and mortality, determine species population dynamics, seasonal and spatial distributions,...

Transport and coastal zooplankton communities in the northern California Current system

Creator:: Bi, Hongsheng, Peterson, William T., and Strub, Paul T.
Abstract:: Alongshore transport was estimated from the gridded AVISO altimeter data and water level data from NOAA tide gauges (1993–2010) for the northern California Current (NCC) system. The biomass of the cold neritic copepods including Calanus marshallae, Pseudocalanus mimus and Acartia longiremis (dominants in the eastern Bering Sea, coastal Gulf of...

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...

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...

Environmental drivers and reproductive consequences of variation in the diet of a marine predator

Creator:: Gladics, Amanda J., Suryan, Robert M., Parrish, Julia K., Horton, Cheryl A., Daly, Elizabeth A., and Peterson, William T.
Abstract:: Ocean conditions can greatly impact lower trophic level prey assemblages in marine ecosystems, with effects of ocean state propagating to higher trophic levels. In many regions throughout their range, common murre (Uria aalge) exhibit narrow dietary breadth in feeding chicks and therefore are vulnerable to recruitment failures of dominant prey...

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...

Marine environment-based forecasting of coho salmon (Oncorhynchus kisutch) adult recruitment

Creator:: Rupp, David E., Wainwright, Thomas C., Lawson, Peter W., and Peterson, William T.
Abstract:: Generalized additive models (GAMs) were used to investigate the relationships between annual recruitment of natural coho salmon (Oncorhynchus kisutch) from Oregon coastal rivers and indices of the physical ocean environment. Nine indices were examined, ranging from large-scale ocean indicators, e.g., Pacific Decadal Oscillation (PDO), to indicators of the local ecosystem...
