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. Usi...
