Updraft cells (yellow/white) drovestrong convergent surface winds(white arrows) resulting in
strong (2-3 m/s) surface currents.
Surface height (color slice)variations of a half-meter over 20 km were observed, and wavespropagate along the thermocline(shown in blue).

Inverse Modeling in the California Current System
Deterministic fits of the physical (and biological) observations(inverse method strategy :allows the models to reach a dynamical consistent state, analysis of dynamical balances, eddies, transports …)

Data Assimilation(assimilation to combine different data sources: CTD’s, ADCP, Satellite and others … to aid general studies of the California Current System)

Predictability of physics and biology(dynamical theory :investigate thelimits of predictability timescale and the dynamical basis for predictability)
Ecosystem response to physical forcing(ecosystem model analysis : to what degree is the biology dependent on the physics? What level of compexity is needed in the ecosystem?)Impacts of climate variability : El Niño(sensitivity model experiments : investigate the system response to changes of the mean state (eg. El Niños, Climate shifts …)
