Figure 3. Anomaly time-series of selected biological observations in the California Current System for the period 1980-2001. The base period for calculating mean biomass, abundance or survival is noted in each panel. Panels a-b show biomass of boreal copepods and southern copepods off the west coast of Vancouver Island, British Columbia. Panels c-d show numerical abundance of boreal and southern copepods off Newport, Oregon. Panels e-f show biomass for the euphausiids, Thysanoessa spinifera (a northern species) and Nyctiphanes simplex (a southern species) from off Southern California. Panel g shows the ocean survival rate (ocean entry to spawning return) for coho salmon from the Oregon Production Index (OPI) area from California to Willapa Bay, WA. Panel h shows the annual mean Pacific Decadal Oscillation (PDO) Anomaly, which is an index of sea surface temperature variability poleward of 10ºN. Anomalies for panels a-f are in log units (e.g., an anomaly of 1.0 equals a factor of 10 difference from the base mean). Anomaly for panel g is percent survival (0.05 is a 5% higher survival rate than the base mean). Data are courtesy of David Mackas (a,b), Bill Peterson (c,d), Ed Brinton and Mark Ohman (e,f), and Ric Brodeur (g).
