California Coastal Upwelling Onset Variability: Cross-Shore and Bottom-Up Propagation in the Planktonic Ecosystem
The variability of the California Current System (CCS) is primarily driven by variability in regional wind forcing. In particular, the timing of the spring transition, i.e., the onset of upwelling-favorable winds, varies considerably in the CCS with changes in the North Pacific Gyre Oscillation. Using a coupled physical-biogeochemical model, this study examines the sensitivity of the ecosystem ...
متن کاملPlankton dynamics in a cyclonic eddy in the Southern California Current System
The California Current System is an eastern boundary upwelling system (EBUS) with high biological production along the coast. Oligotrophic offshore waters create cross-shore gradients of biological and physical properties, which are affected by intense mesoscale eddy activity. The influence of eddies on ecosystem dynamics in EBUS is still in debate. To elucidate the mechanisms that influence th...
متن کاملCross-shelf phytoplankton pigment variability in the California Current
Five years (1979–83) of satellite ocean color data from the coastal zone color scanner (CZCS) data are used to calculate cross-shelf transects of phytoplankton pigment concentrations in the California Current and quantify their seasonal and interannual variability. Alongshore means over six regions, Washington– northern Oregon (48.4–42.88N), Cape Blanco to Cape Mendocino (42.8–40.48N), northern...
متن کاملRecord Coastal Upwelling in the California Current in 1999
An extremely unusual level of coastal upwelling in the spring and summer of 1999 over much of the California Current system (CCS) is described, based on direct and indrect observations. Wind and ocean anomalies in 1999, a period characterized by an equatorial La Niiia, are compared to climate trends for the previous several years, and specifically contrasted with the extremes associated with th...
متن کاملPhytoplankton scales of variability in the California Current System: 1. Interannual and cross-shelf variability
[1] In the California Current System, strong mesoscale variability associated with eddies and meanders of the coastal jet play an important role in the biological productivity of the area. To assess the dominant timescales of variability, a wavelet analysis is applied to almost nine years (October 1997 to July 2006) of 1-km-resolution, 5-day-averaged, Seaviewing Wide Field-of-view Sensor (SeaWi...
