Abstract : A series of repeated surveys off northern California during 1987, and 1988 provided the platform for using nutrients, chlorophyl and phytoplankton species as tools to understand the chemical and biological consequences of the energetic jets and eddies of the Coastal Transition Zone (CTZ). Our results from 1987 and 1988, show that the spatial distribution of nutrients and phytoplankton in the California Current system is determined by mesoscale jets and eddies that recur predictably at similar locations every year. Horizontal distribution of nutrients and phytoplankton, while coherent with the advective regime, was not as predicted; strong offshore jets transport water relatively low in nutrients and phytoplankton. These observations suggest that there are processes, for example upwelling along the southern side of the jets, that supply nutrients to the surface. The early model which suggested the strong jets in the CTZ transported by our observations.
